【xG24 Matter开发套件试用体验】蓝牙mesh基本功能开发调试

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：

mesh相关配置

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。
