I had been struggling with getting the Pi and TNC Pi-9k6 (Teensy 3.6) to talk with each other. I have researched this quite a bit and tried every combination I could find. BTW, I did enable serial ports on the Pi and they are listed, but they would not connect.
In desperation, I tried re-flashing the Teensy 3.6. I did it when it was in circuit with the Pi. I think that I may have completely stopped it from working by doing this. Is it possible to do this or am I just reduced to buying a new Teensy? I will remove the Teensy from the board to re-flash or to replace it with new board.
Any advice will be appreciated.
