For debugging purpose, I would like to access to Raspberry Pi serial terminal.
RAK Hat adapter for RAK831 - Raspberry Pi covers all the pins. There are a couple of PINs on Hat Adapter with no clear documentation. Those pins are located next to GPS Antenna connector. They have labels:
- GPIO15 - RXD0
- GPIO14 - TXD0
- GPIO15 is connected to TXD1
- GPIO14 is connected to RXD1
I wonder if I can use mentioned pins to access RaspberryPI serial console. If not, what would be the best way to access to Raspberry Pi Serial Console (with hat adapter and RAK831 gateway assembled)?
Raspberry Pi serial UART connection require physical access to
- Pin 6: Ground
- Pin 8: Tx
- Pin 10: Rx
With best regards
