RE: [BPQ32] Re: 04-27-13 RASPBERRY PI SERIAL PORT CONFIGURATION
- Dave,First make sure there isn't a getty attached to /dev/ttyAMA0 - ps ax | grep gettyTry a bit of elimination. Loop the serial port (either on the pi connector or the converter output).See if BPQ receives it's own packets. If so, the serial port and BPQ are OK. Check that the BPQ port speed matches the KPC speed..If not, try a terminal program instead of BPQ (I use putty, but there are others). set to /dev/ttyAMA0, and see if you receive what is typed. If so, the serial port is ok, and you can check the BPQ config.You can also connect a terminal program with the KPC attached. You should see data as packets are received, though the headers will look odd as they are KISS format.73, John

I had already completed the steps included in the article.The problem is that the KPC is not responding/receiving the BPQ data. I believe it may be a configuration problem on either the RasPI or BPQ.73, DaveWA7RYV

I think you are trying to connect the TNC to the PI serial pins at GPIO.
- They are at 3,3V level, so you have to use 3,3V TTL to RS232 adapter.
- You have to disable serial port login:
Hope this helps
