To create a server with SIM800L, use GPRS to get a dynamic IP from your carrier. Enable TCP listening with AT+CIPSERVER=1,80. Forward incoming data to your M5Stack via serial. Since the IP is dynamic, use a DDNS service or periodically send the IP via SMS/email. Alternatively, have the M5Stack poll a cloud server for commands. SIM800L has limited capabilities, so keep the website simple (raw HTTP requests). Check the SIM800L AT command manual for TCP/IP setup details.

I have no idea. So i just force disconnect if the RSSI of the WiFi is too low.

Hi

Anyone knows what happened? thank you

@lukasmaximus

Thank you. I will try it again after buying the wire

The gpsmodul is from Navspark and the output is not equal NMEA .
Sample: $GNRMC but not $RMC.
The libraries TinyGPS++ and TinyGPS can not work with the output.
