Re: IRLP DTMF Failure

David Cameron - IRLP

The second "bit" is not reading. This is likely a logic issue, most likely caused by a wiring fault. 

If this is a Pi node, check the gpio cable, specifically the pins 10, 11, 12 ,13 and 15. I bet you'll find a wire loose. 

Otherwise, just check all the wiring.

Thanks so much.  I could not remember the command to see the dtmf decode.
It proves what I thought. Tones are not being decoded correctly.  Some are ok but
7 reads as 5
6 reads as 4
3 reads as 1
2 nothing

I dont know what would have happened all of a sudden.
Do you have any ideas?
Thank you so much fro your help

There are several things you can do to troubleshoot. Log in to the node and check the following.

1. Look at the IRLP log file /home/irlp/log/messages See what has happened on the past.

cat log/messages  or
less log/messages

2. Monitor DTMF operation with ‘readinput’ while you are dialing. see what is actually being decoded.

  [real time spill of all action on the radio port
Ctrl-C to quit readinput

3. Try your custom commands using ‘decode’ from the command line.

decode 9200 or
decode <custom-code>
