    --- Enable NB-IOT</br>
|
||
    [\*] Quectel BC28 ---></br>
|
||
    [ ] Gosuncn ME3616</br>
|
||
        [ ] Enable initialize by thread</br>
|
||
        [\*] Enable sample ---> （是否编译测试例程）</br>
|
||
        (-1) Power pin ---> （电源引脚配置，与电路板相关，模块测试无需修改）</br>
|
||
        (-1) Power status pin ---> （电源状态引脚配置，与电路板相关，模块测试无需修改）</br>
|
||
        (uart3) AT client device name ---> （模块连接的UART名字，取决于模块和主板的连接方式）</br>
|
