<![CDATA[How to create a server with sim800l module?]]>I want to create a web server with my sim card. I search on the internet, but there is no example for sim800l. Most of the example are for WiFi or sim900, etc.

I want to command my M5stack (using SIM800) by sending a data from my computer with a simple website. So my M5Stack + Computer both can be connected to internet and my computer will be knowing the IP address of the Sim card.

Thank you

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.

When I run the code, it output lots of error.

Did anyone try GSM.h before?

Thank you
