My friend and I are doing a project and we're stuck on a problem. We tried looking stuff up but it looks like no one documented something similar before.
Basically, what we want to do is have one Arduino (we thought a MKR NB 1500) in a remote location without any available WiFi (or Ethernet) connection be able to host its own Wifi Network. We thought that giving it a SIM card would allow it to communicate to our webserver (API) and to our surprise, it does (yay)! However, we also want people near the Arduino to be able to access the internet. However, that's where we're stuck...
I know that hosting an access point on an Arduino with WiFi is possible. But is it possible for that access point to link the user to the real internet, itself provided by the SIM card?
P.S. : We are open to having two different Arduinos linked together (or more) in order to make this work. We just need to be able to transfer the SIM network to an access point (hotspot basically).
P.P.S : We are also open to using different technologies like ESP controllers... We're just not using a cellular hotspot because of the cost of these things and we want to make it with Arduino or different controllers.
