Has anyone had any success getting the WaveShare SIM7600G-H-M2 4G HAT to communicate to an Arduino via Serial? I have connected RX and Tx pins of Arduino to pins on GPIO
Rx > Tx (pin 8)
Tx > Rx (pin 6)
Gnd > Gnd (pin 4)
I have also flicked on the Dip switches for Serial comms (Rx & Tx) as per the Waveshare Wiki.
I am also not seeing 5V on pins 2 or 4 as I would expect. Am I missing something?
Power to the Hat via Usb-A and separate power to Arduino. Although I would ideally like to power Arduino from the Hat via 5V.
I am using this library: sim7600/sim7600/Arduino/Waveshare_SIM7600X_Arduino_Library at master · aryaggg/sim7600 · GitHub
In serial monitor I just see repeated AT commands.
Any help or guidance would be appreciated.
