I'm trying to implement a Mobile Network (only) for the ESP32 using Arduino IDE. So to be able to connect to website up/download files etc. I need to be able to handle various HTTP PUT/GET/POST requests. However, the available libraries seem to always rely on additional WiFi related libraries. I don't want to have to load those as well, as they are quire bloated and not needed for my use scenario.

What options do I have for minimalist HTTP request libraries that does not rely on WiFi or BT or ETH?

  • do you have some library over 'Mobile Network' or only AT commands? – Juraj Jul 5 at 12:04
  • Only AT commands. So now I have to manually construct the request/response with strings, which is a real PITA. – not2qubit Jul 5 at 12:13
  • I don't know about mobile network Arduino library with Server implementation. it would require a public IP address so not many would use it – Juraj Jul 5 at 14:05
  • I'm not implementing a server, just a connecting client to download files (to the ESP). – not2qubit Jul 5 at 15:30

    sorry. then you can use TinyGSM. github.com/vshymanskyy/TinyGSM – Juraj Jul 5 at 15:33

The TinyGSM library implements Arduino networking Client base class over GSM modem's AT commands. The library is available in Library Manager. enter image description here
