描述 |
|---|---|---|
Mesh 1.0 |
Relay |
接收并通过 advertising bearer 重新传输 mesh message，以便扩展网络 |
Proxy |
接收并在 GATT 和 advertising bearer 之间重新传输 mesh message |
|
Low Power |
在 mesh 网络中可以大幅降低接收占空比，降低功耗运行，需要支持 Friend feature 的节点配合 |
|
Friend |
通过存储支持 Low Power feature 节点的消息，帮助其运行 |
|
Mesh 1.1 |

支持 Provisioning Protocol 中更多的算法 |
Remote Provisioning |
当 Provisioner 超出未 unprovisioned devices 的直接无线电范围时，仍可将其添加到 mesh 网络 |
|
Private Beacons |
提供 Secure Mesh Beacons 的隐私保护 |
|
Directed Forwarding |
通过选择一部分节点将消息从源点中继到目的地，以帮助提高多跳网络的性能 |
|
Subnet Bridge |
支持 mesh 网络的子网桥接 |
|
Binary Large Object Transfer |
使 mesh 设备之间能够传输大量数据 |
|
Device Firmware Update |
使 mesh 设备可以通过 mesh 网络完成固件升级 |
