Good afternoon. This is my first post on this forum. I hope it will prove efficient. Here is my problem that i could use some help on:
GSM SIM800L module, I want to connect it to either Arduino or ESP32 - i am working on both at the same time - arduino is for testing purposes.
End purpose is to send a message to my phone using the GSM SIM800L module.
I have tried quite a lot of wiring, most of the stuff on youtube i have watched.
I have made sure i have the right voltage ( using a variable power supply), I have made sure the SIM card is working - tested on my phone, the GSM SIM800L module is brand new + i have tried with Version 1 and 2 of the SIM800L.
I was told the code itself might be an issue, i have not explored that yet, i was under the impression that a SIM card connects automatically to a network when the module is powered on,
