有时无线透传在无法布线时有很方便的效用，不妨试试蓝牙透传，效果如下： 具体是无线数据->串口数据，串口数据->无线数据，目前前者实现了，后者还有些问题未解决， 实现过程如下，基于工程demo/Bluetooth/peripheral_demo...改成peripheral_uart_demo，同时目录下peripheral_uart_demo/gcc/defconfig文件里工程名也改成peripheral_uart_demo，然后引入串口读写独立接口即把...demo/at_demo下的serial.c、serial.h、serial_debug.h复制到刚才peripheral_uart_demo工程下，由于要无线写以及串口写转无线，所以profile涉及到
