移远AT指令笔记

# 测试
AT - 测试AT指令功能是否正常

# 模块相关
ATI - 查询模块信息
AT+CGMI - 查询模块制造商标识
AT+CGMM - 查询模块型号
AT+CGMR - 查询模块固件版本号

# 网络相关
AT+QCCID - 查询集成电路卡识别码（ICCID）
AT+GSN / AT+CGSN - 查询国际移动设备识别码（IMEI）
AT+CNUM - 查询手机号
AT+CPIN? - 查询SIM卡是否正常，返回ready则表示SIM卡正常
AT+COPS? - 查询当前注册的网络运营商
AT+CSQ - 查询模组的信号强度，第一个值为0-31则正常(99为无信号），数值越大表明信号质量越好（但是前提必须限定在0-31内）
AT+CGATT? - 查询是否成功注册网络，直到收到 +CGATT: 1；
AT+CREG? / AT+CGREG? - 查询模组是否注册上GSM网络，+CREG:0,1 表示已注册上本地网，+CREG:0,5表示注册上漫游网。

# 配置与激活PDP上下文
AT+CGDCONT=1,"IP","CMNET" - 配置PDP上下文参数（APN） 移动 CMNET，联通 UNINET
AT+CGACT=1,1 - 激活PDP
AT+CGPADDR=1 - 显示PDP地址
AT+QIOPEN=1,0,"TCP","134.175.123.194",6501,0,0 - 建立TCP连接
AT+QICLOSE=0 - 关闭连接
