Functions

bool lls_set_parameter(T_LLS_PARAM_TYPE param_type, uint8_t length, void *p_value)

Set a link loss service parameter.

This function can be called with a link loss service parameter type and it will set the link loss service parameter. Link loss service parameters are defined in T_LLS_PARAM_TYPE. If the “length” field is set to the size of a “uint16_t”, the “p_value” field must point to data with the type “uint16_t”.

Parameters:

• param_type – [in] Link loss service parameter type: T_LLS_PARAM_TYPE.

• length – [in] Length of data to write.

• p_value – [in] Pointer to data to write. This is dependent on the parameter type and will be cast to the appropriate data type (For example: if the data type of param is uint16_t, p_value will be cast to pointer of uint16_t).

Return values:

• true – Operation success.

• false – Operation failure.

Returns:

Operation result.

T_SERVER_ID lls_add_service(void *p_func)

Add link loss service to the Bluetooth Host.

Example usage

void profile_init()
{
    server_init(service_num);
    lls_id = lls_add_service(app_handle_profile_message);
}

Parameters:

p_func – [in] Callback when service attribute was read, write or CCCD update.

Return values:

• 0xFF – Operation failure.

• others – Service ID assigned by Bluetooth Host.

Returns:

Service ID generated by the Bluetooth Host: T_SERVER_ID.
