UART on BG95-M3 Zero EVB

Hi everyone,

I have the BG95-M3 Zero EVB. After I flashed the firmware BG95M3LAR02A03 the UART pins are don’t seem to work anymore. Could you guys tell me what I would need to do to get UART working again?

Many thanks in advance!

Please measure whether the voltage of VDD_EXT (PIN29) is normal, which is 1.8V.

Hi, I just measured it, it is showing 3.3V (also for the other GPIO pins). Is that correct? When I plug in over the usbc port and turn on the USB switch, the AT commands work, but when I want to connect UART over the Pins it doesn´t work anymore.

Thanks in advance!
