General commands steps 2
- AT+CGDCONT=1,"IP","CMNET" //Set APN
- AT+CSQ //Query the quality of the network signal. The first parameter is the maximum network signal quality of 31. The larger the value, the stronger the network signal.
- AT+CREG? //Query the network registration status, where the second parameter is 1 to indicate that the registration has been successful.
- AT+CIPMODE=1 //Set TCP/IP mode
- AT+CSOCKSETPN=1 //Select TCP/IP application mode
- AT+CIPMODE=0 //Select TCP/IP application mode
- AT+NETOPEN //on mode
- AT+CIPOPEN=0,"TCP","113.81.233.65",2317 //Set the TCP, IP and port numbers to establish a TCP/IP connection
- AT+CIPSEND=0,9, //Send 9 characters for the specified data, return > to start sending 9 characters.
- AT+CIPCLOSE=0, //Close the TCP connection
- AT+NETCLOSE, //Close the network
Working with internet domain, and receive data
