GPRSH Command — Socket Disconnection

Forces the disconnection of the active UDP/TCP communication socket (cellular) and also triggers a reconnection of the WiFi module.

What is it for?

🔌 Main use cases:

⚙️ Apply changes to destination IP addresses
🔄 Force reconnection to server
📡 Network or carrier change
📶 Also reconnect the WiFi channel (not just cellular)
🔧 Resolve connection issues
🔁 Restart communication channel

Executing this command interrupts active communication. Use only when necessary to update destination configuration.

Commands

Operation	Syntax	Response
Disconnect	`SGPRSH`	`RGPRSHOK`

SGPRSH reconnects both channels: it forces the disconnection/reconnection of the cellular socket and also reconnects the WiFi module, not just the GPRS/cellular link.

Example


>SIP0"new.server.com",5000<       // Change destination IP
>SGPRSH<                          // Force reconnection with new IP
>RGPRSHOK...                      // Confirmation

Typical server change sequence


>SIP0192.168.1.200/5000<    // New primary IP
>SIP1192.168.1.201/5000<    // New redundant IP
>SGPRSH<                     // Apply changes (reconnection)
