I have a PI Teensy TNC G8BPQ K2MJM v4 I am trying to get working with a Raspberry Pi 3B+ . This board has a Teensy 3.6. I have been able to use the firmware loader to install Pi9K Raspberry Pi Firmware Tennsy36 0416202.hex. Once attached to the RPI I am unable to communicate with the PI TNC via the serial port using pitnc_getparms. Has anyone else worked with this board?
Thanks
