Issue: I got my SIM card activated (Things Mobile), inserted the card into the slot, tried (“at_scan=cellular”) but it gives me an error like this:
Could you help set up the cellular network with the SIM card please?
Also, I am trying to create a function where it tells the current battery level, and once it reaches a certain level, alert the user to recharge. Are there any documents or examples to read the battery level?
Setup: Battery Voltage is stable (the chip is connected to the USB port)
