最近几日学习了蓝牙mesh SDK相关资料,尝试基于Bluetooth Mesh - SoC Light CTL demo来调试验证蓝牙mesh灯控应用的基本功能和使用。

使用原厂的Bluetooth Mesh手机APP来进行mesh组网和控制。
直接烧录运行Bluetooth Mesh - SoC Light CTL 程序,调试串口无反应,手机APP上也搜不到设备。
查看相关文档,有说mesh应用程序需要专用的boot程序:

先编译并烧录Bootloader - SoC Internal Storage (single image on 1536kB device) demo程序,然后再烧录mesh程序,可以正常运行,调试串口有调试信息输出了:

APP上可以扫码到设备了:

点击配网后,配网过程的调试信息如下:

配网后,如视频中,可以使用APP来控制LED的开关,亮度调节等操作。
配网后,按住BTN0然后上电,芯片会恢复出厂设置,即恢复未配网状态,可以进行重新配网:

尝试了使用nRF Mesh和ST的mesh测试APP,能搜索到设备,但配网失败,后续在继续调试研究具体原因,以及作为输入传感器应用的开发调试。
