9.1.1 普通 TCP/TP 发送步骤  
  
AT+CGDCONT=1,“IP”,“CMNET” //设置 APN  
  
OK  
  
  
AT+CSQ //查询信号

OK  
  
  
AT+CGREG?  
  
\+CGREG: 0,1  
  
OK  
  
  
AT+CIPMODE=1 //设置 TCP/IP 模式  
  
OK  
  
  
AT+CSOCKSETPN=1  
  
OK  
  
  
AT+CIPMODE=0  
  
OK  
  
  
AT+NETOPEN  
  
OK  
  
\+NETOPEN: 0  
  
  
AT+CIPOPEN=0,“TCP”,“211.149.158.237”,8011 设置 TCP 、IP 和端口号  
  
OK  
  
\+CIPOPEN: 0,0  
  
  
AT+CIPSEND=0,5 //发数据数据 5 是数据格式 发送 HELLO  
  
>HELLO  
  
OK  
  
  
\+CIPSEND: 0,5,5  
  
RECV FROM:211.149.158.237:8011  
  
\+ IPD19  
  
HOE-7600CE-TCP-TEST //服务器发回的数据  
  
  
AT+CIPCLOSE=0//结束 TCP 连接  
  
OK  
  
CLOSED  
  
\+ CIPCLOSE: 0,0  
  
  
AT+NETCLOSE// Close socket  
  
OK  
  
\+NETCLOSE: 0  
  
  
  
9.1.2 TCP/IP 透传模式发送数据  
  
AT+CGDCONT=1,“IP”,“CMNET”  
  
OK  
  
  
AT+CIPMODE=1  
  
OK  
  
  
AT+NETOPEN  
  
OK  
  
\+NETOPEN: 0  
  
  
AT+CIPOPEN=0,“TCP”,“211.149.158.237”,8011  
  
CONNECT 115200  
  
进入串口透传模式，此时串发过来的任何数据均直接发到服务器上（除+++外）  
  
服务器发过来的数据：  
  
服务器返回数据 HOE-7600CE-TCP-TEST  
  
\+++ 退出透传指令不带回车，发过去串口返回 OK 表示退出透传  
  
OK  
  
  
ATO// 重新进入透传  
  
CONNECT 115200  
  
又可以发数据了

如果透传 TCPIP 连接 先发送+++返回 OK 后发送如下指令

AT+CIPCLOSE=0//结束 TCP 连接  
OK  
CLOSED  
\+CIPCLOSE: 0,0  
  
AT+NETCLOSE// Close socket  
OK

end  
>HELLO<Ctrl+Z>  
OK  
\+CIPSEND: 0,5,5  
AT+CIPCLOSE=0 // close by local  
OK  
\+CIPCLOSE: 0,0  
Note:  
if connection closed by remote server, following URC will return:  
\+IPCLOSE: 0, 1  
Here, the meaning of second parameter in this URC is as following,  
0 - closed by local, active  
1 - closed by remote, passive  
3 - Reset  
  
  
2.3.3 Extended Information  
Command AT+CIPHEAD is used to show IP head (data length) information, and command  
AT+CIPSRIP is used to show remote IP address and port once data are received.

AT+CIPSRIP=0  
AT+CIPOPEN=0,"TCP","116.236.221.75",8011

2.5 Switch between Data Mode and Command Mode  
Hardware flow control is recommended.  
Currently, USB->modem port, USB->AT port and UART port all support hardware flow control.  
Software switching: escape sequence +++. Please take care, this is a complete command, do not  
separate each character, also take care that the time delay before and after this sequence should be  
more than 1000 milliseconds, the interval of each character should not be more than 900  
milliseconds.  
Hardware switching: DTR pin could be used to trigger data mode and command mode.Command  
AT&D1 should be configured before application.  
  
  
2 查询模块网络注册状态  
AT+CPIN?  
\+CPIN: READY // 查询SIM 卡是否识别  
OK  
AT+CSQ  
\+CSQ: 27,99 // 查询信号强度  
OK  
AT+CNSMOD=1 // 设置模块网络制式状态自动上报功能  
OK  
AT+CNSMOD?  
\+CNSMOD: 0,8 // 查询模块注册网  
络制式。8 表示注册在LTE 网络模式  
OK  
AT+CEREG?  
\+CEREG: 0,1 // 此时，表示可以  
进行数据业务了。  
OK  
AT+CNSMOD?  
\+CNSMOD: 0,10 // 查询模块注册在非  
LTE 网络下  
OK  
AT+CGREG?  
\+CGREG: 0,1 // 此时，表示可以进  
行数据业务了。  
OK  
注意：在LTE 网络模式下，请使用AT+CEREG?判断模块数据是否可以使用。  
如果是在其它网络模式下, 请使用AT+CGREG 判断模块数据是否可以使用。  
参数2：返回1(或5)表示数据业务可以使用；返回2、3、4 表示数据业务不可  
用。
