- AT+CMEE=1 // Report UE Error
- ATE1 //Set Command Echo Mode 设置命令回显，就是你发送的指令内容会在串口助手中显示出来
- ATI //查看软件版本号
- AT+CGSN=1 // 查看IMEI号(International Mobile station Equipment Identity) 产品序列号 // +CGSN: 866971030547330
- AT+CESQ //查看信号强度，刚上电入网的时候一般获取信号会比较慢，可以不断的发送这个指令，实时刷新最新的信号状态，大概等30s左右或者更久一点（就像手机刚开机时获取网络信号一样）就能连上网络了。 // +CESQ: 43,99,255,255,30,69 //第一个数为43说明接收信号强度还不错
- AT+QSPCHSC? //查看置乱算法返回值 // +QSPCHSC: 1 //返回1可以入网，返回0的话是入不了网的，需要AT+QSPCHSC=1指令设置成1
