1 功能概述
|
|||
|
|
-------------------------------------
|
|||
|
|
|
|||
|
|
本工程实现了mesh provisioner/provisionnee角色，主要功能有
|
|||
|
|
|
|||
|
|
| 1.作为provisioner发送unprov广播
|
|||
|
|
| 2.作为provisionee加入provisioner组网
|
|||
|
|
| 3.作为灯设备加入天猫精灵组网
|

3 测试过程
|
|||
|
|
-------------------------------------
|
|||
|
|
|
|||
|
|
3.1 多板组网收发
|
|||
|
|
,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,
|
|||
|
|
|
|||
|
|
|
|||
|
|
| 1.A板，输入 ``ble mesh provision init provisioner``
|
|||
|
|
| 2.其他板子输入 ``ble mesh provision init provisionee``，最多20块
|
|||
|
|
| 3.组网成功，A会有打印: ``user_prov_node_added:success, mac xxxxxxxx addr xxx i xxx``
|
|||
|
|
| ``do_add_appkey_cb:bind success, addr xxx appaddr xxx``
|
|||
|
|
| 5.A输入 ``ble mesh provision send_count xxx`` ，xxx为发送间隔(ms)
|
|||
|
|
| 6.正常情况，A会有打印， ``remote C8:47:8C:43:2C:A7 mesh 2, we send X, we recv Y, peer recv Z`` ，其中包括对方地址，mesh地址，X为A发送次数，Y为A接收（此对方）次数，Z为对端接收次数
|
|||
|
|
| 7.其他板子也会有打印 ``peer count X server recv count Y`` ，其中X为A发送次数，Y为本端接收次数。
|
|||
|
|
|
|||
|
|
|
|||
|
|
3.2 天猫精灵外设demo(灯)
|
|||
|
|
,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,
|
|||
|
|
|
|||
|
|
| 1.令天猫精灵进入配网模式
|
|||
|
|
| 2.开发板输入 ``ble_mesh tmall init <product_id> <device_secret>``，等待天猫精灵提示配网成功
|
|||
|
|
| 3.对着天猫精灵说出“开灯”或在手机天猫精灵app控制开关灯，可以看到开发板的led灯受到控制。
