Application Note

Bluetooth Audio Transceiver is an application developed based on Common SDK. It has the capability of Bluetooth, Bluetooth Low Energy, and audio. The host (External MCU) can communicate with Bluetooth Audio Transceiver through the UART interface. Before introducing the functions of the application, a few terms will first be defined:

  • ACI: Application Controller Interface, the communication interface between the ACI Host and Device.

  • ACI Device: Application Controller Interface Device, the chip that runs the Bluetooth Audio Transceiver application.

  • ACI Host: Application Controller Interface Host, the host can be an external MCU chip or PC, which must support the UART interface.

Bluetooth Audio Transceiver ACI

The objective of this ACI UART Transport Layer is to enable the use of the RTK Vendor Command set over a serial interface between two UARTs. The ACI Device provides common functions, such as power on, power off, factory reset, recording from the local MIC, local playback audio from ACI Host, HFP AG/HF, A2DP Source/Sink, etc.

These features are demonstrated in four different types of demo applications: Bluetooth Audio Transmitter, Bluetooth Audio Receiver, Bluetooth Audio Transceiver, Bluetooth Audio Transmitter MP3, and Bluetooth Audio Integrated Transceiver. Later sections will detail the features supported by each scenario type and the flowcharts for implementing these features.

Bluetooth Audio Transmitter

The system block diagram shown below consists of 4 parts: Phone, ACI Host, ACI Device, Headset. Different modules use various interfaces to communicate with each other:

  • Phone <-> ACI Device: Communication with Bluetooth/Bluetooth Low Energy.

  • ACI Host <-> ACI Device: Communication with UART.

  • ACI Device <-> Headset: Communication with Bluetooth/Bluetooth Low Energy.

  • MIC is connected to the internal codec.

../../../_images/bt_audio_transmitter.png

Bluetooth Audio Transmitter

The ACI Host connects with the ACI Device via the UART interface. Through the RTK Command set, the ACI Host controls the ACI Device into pairing mode, as well as active scanning and pairing with the Headset. In this application, the ACI Device acts as a Bluetooth Low Energy Peripheral. It will advertise and accept Bluetooth Low Energy connect requests from the mobile phone, and the phone can control the ACI Device through the Bluetooth Low Energy connection. The audio data flow is identified by the blue line with arrows.

For the Bluetooth link with the Headset, the ACI Device acts as the Source of A2DP or AG of HFP and can play the audio data from MIC, Line-in, or I2S to the Headset through the A2DP or SCO link.

Bluetooth Audio Receiver

The system block diagram is shown as follows, consisting of 3 parts: Phone, ACI Host, ACI Device, different modules use various interfaces to communicate with each other:

  • Phone <-> ACI Device: Communication with Bluetooth/Bluetooth Low Energy.

  • ACI Host <-> ACI Device: Communication with UART.

  • ACI Device <-> Headset: Communication with Bluetooth.

  • MIC and SPK are connected to the internal codec.

../../../_images/bt_audio_receiver.png

Bluetooth Audio Receiver

In this application, ACI Device acts as Bluetooth Low Energy Peripheral, it will advertise and accept Bluetooth Low Energy connect requests from the mobile phone, and the phone can control ACI Device through Bluetooth Low Energy connection. The audio data flow is identified by the blue line with arrows.

For the Bluetooth link with the cell phone, ACI Device acts as the HF role of HFP and A2DP Sink role of A2DP, which can play music and handle phone calls.

Bluetooth Audio Transceiver

The system block diagram is shown as follows, which consists of 5 parts: Phone, ACI Host, ACI Device 1, ACI Device 2, Headset, different modules use various interfaces to communicate with each other:

  • Phone <-> ACI Device 1: Communication with Bluetooth/Bluetooth Low Energy.

  • ACI Host <-> ACI Device 1: Communication with UART.

  • ACI Host <-> ACI Device 2: Communication with UART.

  • ACI Device 1 <-> ACI Device 2: Communication with SPI and GPIO.

  • ACI Device 2 <-> Headset: Communication with Bluetooth/Bluetooth Low Energy.

../../../_images/bt_audio_transceiver.png

Bluetooth Audio Transceiver

ACI Device 1 supports A2DP Sink and HFP HF; ACI Device 2 supports A2DP Source and HFP AG. The audio data flow is identified by the blue line with arrows:

  • In A2DP scenario:

    • Audio data are routed as follows: Phone -> ACI Device 1 -> ACI Device 2 -> Headset.

  • In SCO scenario:

    • Downstream voice data are routed as follows: Phone -> ACI Device 1 -> ACI Device 2 -> Headset SPK.

    • Upstream voice data are routed as follows: Headset MIC -> ACI Device 2 -> ACI Device 1 -> Phone.

Bluetooth Audio Transmitter MP3

The system block diagram is shown as follows in the figure below:

../../../_images/bt_audio_transmitter_mp3.png

Bluetooth Audio Transmitter MP3

The system block diagram is the same as bt_audio_transmitter. The only difference is that the audio data is from ACI Host CLI Tool. The audio data flow is identified by the blue line with arrows:

  • For the ACI Device itself, the audio data received from the ACI Host can not only be played out through the A2DP Source to the Headset but also through the local SPK, similarly, audio data sampled through the ACI Device’s MIC can also be sent to the ACI Host through the ACI.

  • For the Bluetooth link with the Headset, the ACI Device acts as the Source of A2DP and can play the audio data from ACI Host to the Headset through the A2DP link.

Bluetooth Audio Integrated Transceiver

The system block diagram is shown as follows, which consists of 4 parts: Phone, ACI Host, ACI Device, Headset. Different modules use various interfaces to communicate with each other:

  • Phone <-> ACI Device: Communication with Bluetooth.

  • ACI Host <-> ACI Device: Communication with UART.

  • ACI Device <-> Headset: Communication with Bluetooth.

../../../_images/bt_audio_transceiver_single_chip.png

Bluetooth Audio Integrated Transceiver

ACI Device supports both A2DP Sink/Source role and HFP HF/AG role. As a feature of this application, ACI Device needs to be connected to Phone and Headset at the same time. The audio data flow is identified by the blue line with arrows.

Experimental Verification

After programming the application bin to the EVB board, testing can be done with a Bluetooth headset or a mobile phone, depending on the specific application type of the bin. The following sections introduce the message sequence charts and implementation steps of each application demo bin, which are divided into:

Message Sequence Charts

This chapter shows typical interactions between Application Controller Interface (ACI) commands and events. It focuses on the message sequence charts (MSCs) for the procedures specified in Design Specification. This chapter illustrates only the most useful scenarios; it does not cover all possible alternatives. In all message sequence charts, it is assumed that all events are not masked, so the Controller will not filter out any events.

The sequence of messages in these message sequence charts is for illustrative purposes. The messages may be sent in a different order where allowed by the ACI. If any of these charts differ from the text in the ACI Parts, the text in those Parts overrides these charts.

Notation

The notation used in the message sequence charts consists of ovals, elongated hexagons, boxes, lines, and arrows. The vertical lines terminated on the top by a shadow box and at the bottom by a solid oval indicate a protocol entity that resides in a device. MSCs describe interactions between these entities and the states those entities may be in.

The following notations represent interactions and states.

Notations

Notation

Description

Oval

Defines the context for the message sequence chart.

Hexagon

Indicates a condition needed to start the transaction below this hexagon. The location and width of the Hexagon indicate which entity or entities make this decision.

Box

Replaces a group of transactions. May indicate a user action, or a procedure in the link layer.

Note

Gives an explanation of an element.

Alt/Else

Performs the appropriate action based on the alternative condition.

Loop

Repeats the loop to perform some behavior.

Control Flow

Some message sequences are split into several charts. In these charts, numbers indicate normal or required ordering, and letters represent alternative paths. For example, Step 4 is after Step 3, and Step 5a could be executed instead of Step 5b.

Example MSC

The protocol entities represented in the example illustrate the interactions of two devices named A and B, each device includes a Host and a link layer entity in this example. Other MSCs in this chapter may show the interactions of more than two devices.

Forward Compatibility

Many of the message sequences in this part use ACI Commands or events that have enhanced or extended variants that were added to the specification later than the relevant sequence. Such variants can be related commands or events with different names or commands or events with multiple versions. In some instances, a Host is required to use the new variant rather than the one shown in the MSC. Even when this is not a requirement, Host implementers may prefer to use the newer variants.

In these circumstances, the MSCs have not been rewritten to use newer features but have been left unchanged. In general, the new commands and events will directly replace the old ones, but this is not always the case and readers should not assume it.

Basic Functions

This chapter introduces some basic features, which are supported in various application scenarios. This chapter describes how to use these functions and the flow for testing them, including the MSCs of the ACI Device and ACI Host interaction, and the commands used.

Power On/Off and Factory Reset

Power on, power off, and factory reset functions are introduced in this chapter:

  • Power on state: The execution of any function must ensure that the system is in the power on state.

  • Power off state: The APP layer will do the corresponding processing to make DSP enter a power off state. Since the power on state will enter DLPS mode automatically, the power off state cannot be set.

  • Factory reset: This function can clear Bluetooth pairing information and reset FTL information. This command needs to be executed once after downloading.

Power On

The chip needs to execute the power on command after downloading.

Note

Using ACI Host CLI test may require sending the mmi pwron command multiple times to wake up the chip. This problem will not exist when the ACI Host wakes up the chip through GPIO. When there is no task, the chip in power on state will enter DLPS mode automatically.

The ACI Host CLI CMD for power on is mmi pwron, the corresponding UART CMD packet and tool log are as follows.

Factory Reset

Note

Before executing the factory reset command, it is necessary to ensure that the device is in a power on state. Only after the factory reset is executed, the device can enter DLPS mode. As a result, it needs to be executed once after downloading.

After executing the factory reset command, the device will enter the power off state first, and then enter the power on state automatically.

The ACI Host CLI CMD for factory reset is mmi freset, the corresponding UART CMD packet and tool log are as follows.

ACI Host CLI CMD for Factory Reset

Parameters

ACI Host CLI CMD

CMD_MMI = 0x0004

action = MMI_DEV_FACTORY_RESET(0x58)

mmi freset

After the factory reset, the chip will restore from the device state before the factory reset executes.

ACI Host CLI Test: Scan Devices

The ACI Device currently supports two scan commands: CMD_LE_START_SCAN and CMD_LEA_SCAN. These are used to scan all LE devices and devices that support LE Audio respectively. This chapter introduces the CMD_LE_START_SCAN command. For information on the CMD_LEA_SCAN command, please refer to chapter Initiator General ACI Host CLI Test. Please note, after scanning the devices, both commands report information through the EVENT_LE_AUDIO_SCAN_INFO event.

ACI Host CLI Test: Initiate Connection

By entering the le conn_idx command, it is possible to list all scanned devices on the ACI Host CLI Tool. After entering the index of the device to connect with, the ACI Device will initiate a connection with that device, as well as automatically pair and discover services. The initiation of a connection is actually triggered through the CMD_LE_CREATE_CONN command.

ACI Host CLI Test: Operate White List

Using the white list, the ACI Device can only receive broadcasts from devices in the white list, or only establish connections with devices in the white list. The CMD_LE_MODIFY_WHITELIST command allows adding or removing specific devices to and from the white list, and to clear the white list. The CMD_LE_MODIFY_WHITELIST_BY_IDX command allows adding the device with the specified index in the bond list to the white list, or removing it from the white list.

Note

These commands shall not be used when: Any advertising filter policy uses the white list and advertising is enabled, the scanning filter policy uses the white list and scanning is enabled, or the initiator filter policy uses the white list and an HCI_LE_Create_Connection or HCI_LE_Extended_Create_Connection command is outstanding.

ACI Host CLI Test: Operate Resolving List

Similar to the white list, if the device needs to use the link layer privacy mechanism, a resolving list needs to be stored on the Controller. Using CMD_LE_MODIFY_RESOLVELIST_BY_IDX, device with specified index in the bond list can be added to or removed from the resolving list, and the entire resolving list can be cleared.

To enable/disable resolution of resolvable private addresses in the Controller, please use the command CMD_LE_SET_RESOLUTION.

Note

These commands shall not be used when:

  • Advertising (Other than periodic advertising) is enabled.

  • Scanning is enabled.

  • HCI_LE_Create_Connection, HCI_LE_Extended_Create_Connection, or HCI_LE_Periodic_Advertising_Create_Sync command is outstanding.

LE Audio Function

The current version of Bluetooth Audio Transceiver application includes support for LE Audio functionality. LE Audio typically utilizes BIS or CIS to transmit audio data. In the present version, BIS has been implemented. Please note that the LE Audio module only offers protocol and data pathway. Users need to supply data to the LE Audio module by either the transparent transmission module A2DP Transparent Transmission (BIS Output) or the recording module, enabling the transmission of ISO audio data to external devices.

LE Audio Initiator

Initiator, which is described in CAP specification, always operates in BAP Unicast Client role, BAP Broadcast Source role, BAP Scan Assistant role, or CCP Call Control Server role.

Initiator General ACI Host CLI Test

For CIS, it is necessary to establish an LE link, whereas for BIS, it is not mandatory. This chapter delineates the process of establishing an LE link with devices supporting LE Audio Acceptor.

To scan nearby devices supporting LE Audio, ACI Host sends the CMD_LEA_SCAN to enable the scan procedure. The current scan results can be displayed by entering the le conn_idx command. If the device expected to be connected is a stereo headset, directly input the serial number of the headset to establish the connection and complete the pairing. If the device to be connected is a pair of RWS BUDS, input the serial number of either the left or right BUD, and Bluetooth Audio Transceiver application will establish connections for both BUDS simultaneously. Upon completion of the LE Audio-related service discovery, Bluetooth Audio Transceiver application will report the EVENT_LE_AUDIO_BAP_DISCOVERY_DONE event.

BIS Initiator Introduction

BIS, which stands for Broadcast Isochronous Channel, is a communication channel utilized in the context of LE Audio. It is responsible for transmitting audio data wirelessly. BIS is designed to support high-quality audio streaming, allowing the transfer of synchronized audio content from a source device (as broadcast source role) to multiple recipient devices simultaneously.

bsrcstop hold

The ACI Host CLI CMD for BIS are CMD_LEA_BSRC_INIT, CMD_LEA_BSRC_START, and CMD_LEA_BSRC_STOP. CMD_LEA_BSRC_INIT is used to initialize the parameters related to BIS, including codec type, BIS number, encryption mode, ULL mode (Ultra Low Latency mode), and PD (Presentation Delay). The PD parameter is only effective when ULL mode is enabled. When ULL mode is activated, the following parameters are specifically used when creating BIG: Packing = Interleaved, Max Transport Latency = 10 ms, RTN = 2. Additionally, the DSP would periodically fetch the anchor point to capture data at more precise time intervals, aiming for lower and more stable latency. CMD_LEA_BSRC_START is used to activate BIS, while CMD_LEA_BSRC_STOP is used to stop BIS.

CIS Acceptor Introduction

CIS, which stands for Unicast Isochronous Channel, is a logical transport for connected devices that allows sending and receiving isochronous data. For a CIS, an acknowledgment protocol is available to increase packet delivery dependability. This chapter describes how to use the CIS Acceptor and can be connected to remote devices. Actually, the CIS Acceptor can control the remote device’s music player and telephone call by MCP and CCP profiles. It will notify VCS audio volume to Initiator when local volume or SPK mute/unmute changes.

The ACI Host CLI CMD for CIS Acceptor is CMD_LEA_CCP_CALL_CP, CMD_LEA_MCP_MEDIA_CP and CMD_LEA_VCS_SET:

  • CMD_LEA_CCP_CALL_CP is used to control the remote device’s telephone call when they are connected to LE Audio. And it can send accept, terminate, local hold, local retrieve, originate and join commands by CCP profile.

  • CMD_LEA_MCP_MEDIA_CP is used to control the remote device’s active music player when they are connected to LE Audio. And it can send play, pause, stop, fast rewind, fast forward, previous track, and next track commands by the MCP profile.

  • CMD_LEA_VCS_SET is used to change the volume of the local device’s audio and the CIS Acceptor will notify the VCS audio volume state to the remote device.

Bluetooth Audio Transmitter

This chapter introduces the functionality of the bt_audio_transmitter application scenario. This functionality is enabled by opening the macro definition F_APP_BT_AUDIO_TRANSMITTER_DEMO_SUPPORT in app_flags.h. This chapter describes how to use these functions and the flow of how to test them, including the MSCs of the ACI Device and ACI Host interaction, and the commands used by ACI Host CLI Tool.

Source Play Function

Based on the scenario introduced at the beginning of the article, the Bluetooth Audio Transceiver application supports source play function, which can transmit MIC, Line-in, USB, SD card signal to BUDs through HFP, A2DP or BIS/CIS. These input and output methods can be combined in various ways by set_route_in CMD and set_route_out CMD. This chapter presents three combinations as examples:

MIC Source Play

Before using, configure MIC 1 on the EVB and connect an external MIC. After connecting the MIC and starting the recording, the recorded data will be sent to the connected BUD via HFP. The MIC source playback process is:

../../../_images/bt_audio_trx_mic_src_play.png

ACI Host CLI Test: MIC Source Play
ACI Host CLI CMD for MIC Source Play

Command

Parameters

ACI Host CLI CMD

CMD_SRC_PLAY_SET_SRC_ROUTE(0x3300)

action = mic(0x01, 0x00)

set_route_in mic

CMD_SRC_PLAY_SET_PLAY_ROUTE(0x3302)

action = hfp_ag(0x02)

set_route_out hfp_ag

CMD_SRC_PLAY_ROUTE_IN_START(0x3304)

None

route_in start

CMD_SRC_PLAY_ROUTE_IN_STOP(0x3305)

None

route_in stop

CMD_SRC_PLAY_ROUTE_OUT_START(0x3306)

None

route_out start

CMD_SRC_PLAY_ROUTE_OUT_STOP(0x3307)

None

route_out stop

The ACI Host sends CMD_SRC_PLAY_SET_SRC_ROUTE to ACI Device to set the MIC input route, sends CMD_SRC_PLAY_SET_PLAY_ROUTE to set HFP output route, sends CMD_SRC_PLAY_ROUTE_IN_START or CMD_SRC_PLAY_ROUTE_IN_STOP to start or stop the MIC input route, and sends CMD_SRC_PLAY_ROUTE_OUT_START or CMD_SRC_PLAY_ROUTE_OUT_STOP to start or stop the HFP output route.

Line-in Source Play (BIS Output)

Before using, please configure MIC 2 on the EVB and connect to PC through Line-in. After Line-in is connected and music on the PC is started, the music data could be sent to the BUD(s) through BIS.

BIS supports configuring codec type (48k/16k), BIS number (1 BIS containing dual-channel data or 2 BIS containing separate L and R channel data), ULL mode (E2E Latency < 30ms), and other parameters. For details, please refer to ACI_CMD_LEA_BSRC_INIT.

ACI Host CLI Test: Line-in Source Play (BIS Output)

When using BIS as output path, it is necessary to initialize BIS first through CMD_LEA_BSRC_INIT. The ACI Host sends CMD_SRC_PLAY_SET_SRC_ROUTE to ACI Device to set the Line-in input route, sends CMD_SRC_PLAY_SET_PLAY_ROUTE to set BIS output route, sends CMD_SRC_PLAY_ROUTE_IN_START/STOP to start or stop the Line-in input route, and sends CMD_SRC_PLAY_ROUTE_OUT_START/STOP (Other than CMD_LEA_BSRC_START/STOP) to start or stop the BIS output route.

Line-in Source Play (CIS Output)

Before using, please configure MIC 2 on the EVB and connect to PC through Line-in. After Line-in is connected and music on PC is started, the music data can be sent to the connected BUD(s) through CIS.

In this scenario, CIS supports only the downlink direction of the datapath. The codec type is determined through negotiation (Refer to app_lea_ini_select_media_prefer_codec()). In ULL mode (Configured through the CMD_LEA_CIS_ULL_MODE command, and E2E Latency < 30ms), 48_1 is preferred, while in non-ULL mode, 48_6 takes precedence.

CIS connection process: Please refer to ACI Host CLI Test: Advertising.

USB Source Play (BIS Output)

Before using, please connect EVB to PC through USB, select EVB as the audio device. After USB cable is connected and music on PC is started, the music data could be sent to the BUD(s) through BIS.

BIS supports configuring codec type (48k/16k), BIS number (1 BIS containing dual-channel data or 2 BIS containing separate L and R channel data), ULL mode (E2E Latency < 30ms), and other parameters. For details, please refer to ACI_CMD_LEA_BSRC_INIT.

USB Source Play (BIS Output)

ACI Host CLI Test: USB Source Play (BIS Output)

When using BIS as the output path, it is necessary to initialize BIS firstly through CMD_LEA_BSRC_INIT. The ACI Host sends CMD_SRC_PLAY_SET_SRC_ROUTE to ACI Device to set the USB input route, sends CMD_SRC_PLAY_SET_PLAY_ROUTE to set BIS output route, sends CMD_SRC_PLAY_ROUTE_IN_START/STOP to start or stop the USB input route, and sends CMD_SRC_PLAY_ROUTE_OUT_START/STOP (Other than CMD_LEA_BSRC_START/STOP) to start or stop the BIS output route.

USB Source Play (CIS Output)

Before using, please connect EVB to PC through USB, select EVB as the audio device. After USB cable is connected and music on PC is started, the music data could be sent to the BUD(s) through CIS.

In this scenario, CIS only sets up the downlink direction of the datapath. The codec type is determined through negotiation (Refer to app_lea_ini_select_media_prefer_codec()). In ULL mode (Configured through the CMD_LEA_CIS_ULL_MODE command, and E2E Latency < 30ms), 48_1 is preferred, while in non-ULL mode, 48_6 takes precedence.

CIS connection process: Please refer to ACI Host CLI Test: Advertising.

USB Source Play (CIS Input and Output)

Before using, please connect the EVB and PC through USB and select the EVB as the audio device. Once the USB cable is connected, calls or simultaneous recording and playing of music can be initiated on the PC. The USB downstream data, transferred to the EVB, can be sent to BUD(s) through the CIS, and the data received from the BUD(s) through CIS can be transmitted upstream to the PC through USB.

In this scenario, CIS will set up both downlink and uplink directions of the datapaths. The codec type is determined through negotiation (Refer to app_lea_ini_select_conversation_prefer_codec()), and 16_2 is preferred.

CIS connection process: Please refer to ACI Host CLI Test: Advertising.

SD Card Source Play (BIS/CIS Output)

Before using, please make preparations as described in SD Card Source Play. The music data could be sent to the BUD(s) through BIS.

Note

DSP bin under release bin\DSP_Image\cs_leaaudio_pipe_stereo should be downloaded.

After SD card is inserted, the SD card source play can be started. SD card source play process:

SD Card Source Play (BIS/CIS Output)

ACI Host CLI Test: SD Card Source Play (BIS/CIS Output)

When using BIS as output path, it is necessary to initialize BIS firstly through CMD_LEA_BSRC_INIT. The ACI Host sends CMD_SRC_PLAY_SET_SRC_ROUTE to ACI Device to set the SD card input route, sends CMD_SRC_PLAY_SET_PLAY_ROUTE to set BIS/CIS output route, sends CMD_SRC_PLAY_ROUTE_IN_START/STOP to start or stop the SD card input route, and sends CMD_SRC_PLAY_ROUTE_OUT_START/STOP to start or stop the BIS output route.

Attach Feature to Source Play

The source play interface, in addition to providing basic audio stream configuration, also supports the attachment of additional features. Currently supported features include:

  • NREC: Noise reduction algorithm for audio recording.

  • Append LOCAL PLAY: Simultaneous play through the local speaker alongside the basic audio stream.

The CMD_SRC_PLAY_ATTACH_FEATURE command is used to configure the required features. Different features have different usage scenarios, and not all combinations of source routes and play routes support all features. Therefore, users must first configure the source route and play route before attaching the desired features. Additionally, the attachment of features must be completed before initiating CMD_SRC_PLAY_ROUTE_OUT_START or CMD_SRC_PLAY_ROUTE_IN_START.

Additionally, users can use the CMD_SRC_PLAY_DETACH_FEATURE command to disable any previously configured features. This command shall be executed before initiating CMD_SRC_PLAY_ROUTE_OUT_START or CMD_SRC_PLAY_ROUTE_IN_START.

  1. Scenarios for NREC The supported scenarios for NREC are as follows.

    Scenarios for NREC

    Route in (Source Route)

    Route out (Play Route)

    MIC

    CIS

    BIS

    Note

    The NREC algorithm only supports 16k and 32k sampling rates. Therefore, when NREC is attached, users shall ensure that BIS is initiated to 16k, while CIS will preferentially use 16k by default.

  2. Scenarios for Append LOCAL PLAY The supported scenarios for NREC are as follows.

Bluetooth Audio Receiver

This chapter introduces the functionality of the bt_audio_receiver application scenario. This functionality is enabled by opening the macro definition F_APP_BT_AUDIO_RECEIVER_DEMO_SUPPORT in app_flags.h. This chapter describes how to use these functions and the flow of how to test them, including the MSCs of the ACI Device and ACI Host interaction, and the commands used by ACI Host CLI Tool.

HFP Function

ACI Host CLI Test: HFP Function
ACI Host CLI CMD for HFP

Command

Parameters

ACI Host CLI CMD

Description

CMD_MMI = 0x0004

action = MMI_HF_ANSWER_CALL(0x0003)

mmi answer

Answer an incoming call.

CMD_MMI = 0x0004

action = MMI_HF_REJECT_CALL(0x0004)

MAP Function

Based on the scenario introduced in Connect to Phone, MAP can be used to combine the messaging capabilities of a messaging server device and the user interface capabilities of a client device for browsing, reading, and sending messages.

Before using the MAP function, it is necessary to enable Message access on Android devices, and enable Show Notifications on iOS devices.

MAP

../../../_images/bt_audio_trx_map_get_handle.png

MAP Get Handle

As introduced in the figure, after the MAP connection is established, the device will set a folder to root\telecom\msg. The parameters of CMD_MAP_GET_MESSAGE need to be set according to the handle value of the specific message in the message list.

ACI Host CLI Test: MAP Function

The ACI Host uses CMD_MAP_CONNECT with a status parameter to the ACI Device to establish a MAP connection, uses CMD_MAP_GET_FOLDER_LISTING, CMD_MAP_GET_MESSAGE_LISTING, and CMD_MAP_GET_MESSAGE to get folders and messages, and uses CMD_MAP_REG_MSG_NOTIFICATION to register message notifications.

BIS Acceptor Function

If an assistant exists, the sink could connect with an assistant and ask the assistant to assist it for scanning and get the extended advertising and periodic advertising information. If the assistant doesn’t exist, the sink needs to sync the source autonomously.

Bluetooth Audio Transceiver

This chapter introduces the functionality of the bt_audio_transceiver application scenario. This functionality is enabled by opening the macro definition F_APP_BT_AUDIO_TRANSCEIVER_DEMO_SUPPORT in app_flags.h. This chapter describes how to use these functions and the flow of how to test them, including the MSCs of the ACI Device and ACI Host interaction, and the commands used by ACI Host CLI Tool.

A2DP Transparent Transmission (A2DP Output)

Two typical application scenarios are introduced at the beginning of the article. Based on the A2DP scenario, A2DP data can be transferred from the Phone, through ACI Device 1 and ACI Device 2, to the Headset. This function is called A2DP Transparent Transmission.

A2DP Transparent Transmission process:

../../../_images/bt_audio_trx_a2dp_transfer.png

A2DP Transparent Transmission

ACI Device 1 and ACI Device 2 transmit data through SPI. The SPI role of ACI Device 1 is master and that of ACI Device 2 is the slave. Please set flag F_APP_SPI_ROLE_MASTER on ACI Device 1 and set flag F_APP_SPI_ROLE_SLAVE on ACI Device 2 to enable SPI before building the application.

The AVDTP data format between Phone and ACI Device 1 may be different from that between ACI Device 2 and Headset. To solve this mismatch, the Audio Pipe is introduced on ACI Device 2 to convert the format in the route of Phone -> ACI Device 1 to that in the route of ACI Device 2 -> Headset.

ACI Host CLI Test (A2DP Transfer)

Before using the function, the hardware environment needs to be configured:

  1. Bluetooth address modification: Use the MCUConfig Tool to modify the Bluetooth address of ACI Device 2 to make it different from ACI Device 1.

  2. SPI wiring preparation: The recommended connection is P0_0(SPI_SCK), P1_0(SPI_MOSI), P0_1(SPI_MISO), P1_1(SPI_CS), P2_1(PIN_GPIO) and GND of ACI Device 1 and ACI Device 2. Developers can connect according to the pin settings in board.h.

The play route of Device 2 should be configured to A2DP Source through CMD_A2DP_XMIT_SET_ROUTE_OUT. The ACI Host sends CMD_A2DP_XMIT_ROUTE_OUT_CTRL with status param to ACI Device 2 to start or stop processing and sending data to Headset. The corresponding UART CMD packet and tool log are as follows.

A2DP Transparent Transmission (BIS Output)

LE Audio is a new Bluetooth wireless standard for transmitting audio. LE Audio operates on the Bluetooth Low Energy radio, which is different from Classic Audio (like A2DP or HFP) that operates on the Bluetooth Classic radio. LE Audio transmits streams through BIS (Broadcast Isochronous Streams) or CIS (Connected Isochronous Streams). Currently, the Bluetooth Audio Transceiver application supports broadcasting audio through BIS.

As a broadcaster, the audio data for broadcasting is necessary. Based on the typical A2DP scenario (Refer to Bluetooth Audio Transceiver), we use the AVDTP data received from the Phone by ACI Device 1 as the raw data for ACI Device 2. The received AVDTP data would be converted to LC3 format supported by LE Audio through the Audio Pipe. On ACI Device 2, a BIG with 1 or 2 BIS would be set up and broadcast the converted LC3 data externally. The topology is shown in the figure below.

../../../_images/bt_audio_trx_broudcast_source_topology.png

Broadcast Source Topology

Before enabling the broadcast source feature, please ensure that the LE isochronous function and PA function are enabled in the MCUConfig Tool, and at least 1 BIG, 2 BIS, and 1 PA are set up.

ACI Host CLI Test (BIS Transfer)

The ACI Host sends CMD_LEA_BSRC_INIT to ACI Device 2 to configure the codec type, BIS number, and encryption mode. The play route of Device 2 should be configured to BIS through CMD_A2DP_XMIT_SET_ROUTE_OUT, and the ACI Host sends CMD_A2DP_XMIT_ROUTE_OUT_CTRL with status param to ACI Device 2 to start or stop processing and sending data to Headset.

HFP Transparent Transmission

Based on the SCO scenario introduced at the beginning of the article, HFP transparent transmission can be realized by transmitting SCO data from the Phone, through ACI Device 1 and ACI Device 2, to the Headset.

ACI Device 1 and ACI Device 2 transmit data through SPI. The SPI role of ACI Device 1 is master, and that of ACI Device 2 is the slave. Similar to 6.1.1, please set the flag F_APP_SPI_ROLE_MASTER on ACI Device 1 and set the flag F_APP_SPI_ROLE_SLAVE on ACI Device 2 before building.

HFP Transparent Transmission process:

../../../_images/bt_audio_trx_hfp_transfer.png

HFP Transparent Transmission

In addition, the operations of answering, hanging up, muting the MIC, and increasing or decreasing the speaker volume can be realized only by the host.

HFP Transparent Transmission Host Control

ACI Host CLI Test (HFP Transfer)

Before using the function, the hardware environment needs to be configured:

  • Bluetooth address modification: Use MCUConfig Tool to modify the Bluetooth address of ACI Device 2 to make it different from ACI Device 1.

  • SPI wiring preparation: The recommended connection is P0_0(SPI_SCK), P1_0(SPI_MOSI), P0_1(SPI_MISO), P1_1(SPI_CS), P2_1(PIN_GPIO), and GND of ACI Device 1 and ACI Device 2. Developers can connect according to the pin settings in board.h.

The ACI Host sends SPI_AG_SCO_CONNECT with status param to ACI Device 2 to connect the SCO link between ACI Device 2 and the Headset to send data. Correspondingly, the ACI Host sends SPI_AG_SCO_DISCONNECT to ACI Device 2 to disconnect the SCO link between ACI Device 2 and the Headset. The ACI Host CLI commands are hfpag conn and hfpag disconn. If the phone supports an outband ringtone, commands such as hfpag call_incoming, hfpag call_answer, and hfpag call_terminate are required to make the Headset simulate playing/stopping the ringtone and dropping calls.

The corresponding UART CMD packet and tool log are as follows.

HFP Integrated Transceiver Transmission

Based on the HFP transmission, SCO data can be transferred from the Phone, through ACI Device to the Headset. HFP integrated transceiver transmission process:

../../../_images/bt_audio_trx_single_chip_hfp_transfer.png

HFP Integrated Transceiver Transmission

ACI Host CLI Test: Integrated Transceiver (HFP Output)

ACI Host sends CMD_HFP_AG_CONNECT_SCO to ACI Device to connect the SCO link between ACI Device and Headset to send data. ACI Host sends CMD_HFP_AG_DISCONNECT_SCO to ACI Device to disconnect the SCO link between ACI Device and the Headset. ACI Host CLI commands are hfpag conn and hfpag disconn. Before using the function, inquiry and page scan should be set as disable. Since there are two SCO links in this scenario, CMD_SRC_PLAY_SET_MULTI_ESCO is used to support the coexistence of two links.

UART DFU

Introduction

DFU (Device Firmware Upgrade) function allows for seamless firmware updates. Bluetooth Audio Transceiver has incorporated a comprehensive DFU system based on UART. This system enables users to upgrade devices effortlessly through the utilization of the ACI Host CLI Tool. By placing the designated upgrade package into a specified folder and configuring the file name and version number, users can execute the device update with a single command.

Prepare the Upgrade Package

In order to perform a DFU process, it is necessary to prepare an upgrade package. The creation of the upgrade package can be accomplished using the MPPG Tool. This involves two main steps:

  1. Generating the OTA header image. During this process, please ensure the appropriate version number is filled in (This version number will later need to be entered in the config.yml file in ACI Host CLI Tool). For detailed instructions, refer to Prepare the Image to Update.

  2. Packing the generated OTA header image with other images to be upgraded. For detailed instructions, refer to Pack Whole Image.

Once the upgrade package is prepared, place it in the sdk\tool\AciHostCLI-v1.x.x.xx-Common_SDK\dfu folder. Then, open the config.yml file and fill in the upgrade package’s file name and version number.

../../../_images/bt_audio_trx_uart_dfu_file.png

Upgrade Package Configuration

Upon completing the aforementioned steps, simply enter the command dfu start in the ACI Host to initiate the upgrade process for your device.

ACI Host CLI Test: UART DFU

The ACI Host sends CMD_UART_DFU with various opcodes to execute specific functions. This includes using the UART_DFU_START_REQ opcode to initiate the DFU, the UART_DFU_DATA_IND opcode to transmit data packets, the UART_DFU_REBOOT opcode to reboot the device, and the UART_DFU_ABORT opcode to terminate the DFU. The device side sends the EVENT_DFU_START_RSP event to confirm the initiation of the DFU, the EVENT_DFU_DATA_REQ event to request data packets, and the EVENT_DFU_RESULT event to notify the ACI Host of the upgrade result.

Auracast™

Introduction

Auracast™ is a breakthrough technology based on the Bluetooth LE Audio specification. It offers an efficient and convenient solution for public broadcasting and multi-device audio sharing, drastically transforming the way people interact with others and surrounding environment. This Bluetooth Audio Transceiver application provides a comprehensive solution that fully supports Auracast™ Transmitter, Receiver, and Assistant roles.

Auracast™ Role: Transmitter

The Auracast™ Transmitter is a Bluetooth device capable of transmitting an Auracast™ broadcast. In this application, the Bluetooth Audio Transmitter Demo has BAP_BROADCAST_SOURCE enabled in app_lea_flag.h by default to activate this feature. As a broadcast source, the Transmitter requires audio data for transmission. The Source Play module effectively fulfills this role by providing configurable audio paths. It facilitates the acquisition of audio from inputs such as USB, mic, and I2S, enabling transmission through the BIS.

Auracast™ Role: Receiver

The Auracast™ Receiver is a Bluetooth device capable of receiving an Auracast™ broadcast. In this application, the Bluetooth Audio Receiver Demo has F_APP_TMAP_BMR_SUPPORT enabled in app_lea_flag.h by default to activate this feature. This application supports synchronizing with a random broadcast source, synchronizing with a specified address broadcast source, and initializing as a Scan Delegator to synchronize broadcast sources via the Auracast™ Assistant. In this chapter, we will initialize as a Scan Delegator to demonstrate the Auracast™ functionality.

Auracast™ Role: Assistant

The Auracast™ Assistant is a Bluetooth device capable of assisting an Auracast™ Receiver in receiving an Auracast™ broadcast. In this application, the Bluetooth Audio Transmitter Demo has BAP_BROADCAST_ASSISTANT enabled in app_lea_flag.h by default to activate this feature. Typically, an Assistant has a UI interface (like on a mobile phone) to display all of the available Auracast™ transmitters within range, allowing users to select which broadcast source to synchronize with the Receiver. In this chapter’s demonstration, the ACI Host can display the scanned broadcast sources and allows selection through commands.

ACI Host CLI Test

Transmitter

In the demonstration of the source play module, we provide an example using line-in as input and BIS as output. Please refer to the section ACI Host CLI Test: Line-in Source Play (BIS Output).

Receiver

The Receiver shall use the bis_sync_init delegator command to initialize itself as a scan delegator device, and then broadcast advertisement while waiting for the Assistant to establish a BLE connection with it. When the Assistant selects the specified broadcast source, it will transfer the broadcast source information to the Receiver via broadcast adio scan service.

Assistant

The Auracast™ Assistant’s job is to look for all of the available Auracast™ Transmitters within range and then present them to the user in a way that lets them make a choice. Once the user has selected an available broadcast audio stream, the Auracast™ Assistant will synchronize with the specified broadcast source and transfer the sync information to the Receiver via the broadcast adio scan service.

Enter the command baas scan to scan nearby advertisements and filter out Auracast™ Transmitter devices. Then synchronize using the pa_sync command, and send the sync information to the Receiver using bst_start.
