Using the board as 4G and WiFi router

[gittimotap]

Hi

Is it possible to use the board as a WiFi AP to provide connectivity to other devices, but use 4G on the board for the connection for the board itself? Lilygo->4G->Internet Devices->WiFi ->Lilygo->Internet

If yes, do you have any code samples?

This is not a high speed 4G internet board. The Sim7000 is an IOT board for low speed reliable data. Use the Sim7600G or other similar modem to achieve anything faster than 300kbps.

I am interested also in same thing. I do not need fast internet I need reliable connection. Not for mobile devices or computers, but for other IoT devices eg. other ESP32 module.

For sending data in general - yes this board will work. It is made for sending IoT device data. The board provides a stable and reliable connection but at slow speeds - 300Kbps(DL)/375Kbps(UL). See the spec for reference: https://www.simcom.com/product/SIM7000X.html

I am also interested, spesifically if there is any ready code or project that will make the ESP work as a NAT router and forward traffic from other IOT devices connected to a esp32 AP to the internet through a SIM module, be it SIM7000, SIM7006 or other. Speed is not required.

@Kagee not that I'm aware of. I write the code myself if I need specific features. You may be able to find examples that get you close to what you need.
