RAK5010模块sim卡调试，sim卡位电信卡

at+set_config=cellular:(at+cops?)//查看注网

at+set_config=cellular:(at+cfun=?)//查询

at+set_config=cellular:(at+cfun=0)//关sim卡，关射频

at+set_config=cellular:(at+cfun=1)

at+set_config=cellular:(at+cfun=1,1)//重启

如果发送at+cops？返回0则执行以下指令操作
at+set_config=cellular:(at+qcfg="iotopmode",2)

at+set_config=cellular:(at+qcfg="nwscanmode",0)

(执行完就重启，重启后at+cops?还没有返回1就 再次重启，重复上述1命令)
