Re: Raspberry PI won¡¯t TX Direwolf
|
If it's not even attempting to trigger the gpio, there are a couple possibilities....
What does 'systemctl status direwolf' show you?? ?If it's not running as root, it may not have access to the gpio pins
Could also be an error in your config file.
I run mine as a non-priviledged user, and to I had to add an entry to my sisters file so it could access the gpio pins

Thanks for the response.
I have the input and output wired directly to each other with a Baofeng as the transceiver. I simply have two RCA plugs that go to a dismantled baofeng handheld microphone cable. The PTT works by applying the PTT line to ground, that's what's connected to the relay (I'll upgrade this). I certainly can improve the connection as you've suggested but it isn't attempting to output at all nor trying to trigger the GPIO. That's what's strange.
I have?an ICOM IC-7100 with Direwolf connected and it works flawlessly with reception, decoding, and transmission - but this won't attempt to transmit.

Hello Isaiah,
Thank you for closing that Direwolf Github issue and coming here
(or the Direwolf list).? Few things here:
?? 1. Don't use a relay for PTT as you will dramatically impact
your packet performance.? Just use a simple transistor circuit
like this one:
.? There are literally 100s of examples out there on the web:?
"PTT"+circuit
.? Just make you use one that uses a transistor for PTT and has
capacitors to isolate any microphone DC bias voltage.
?? 2. How else have you connected your radio to the soundcard??
It's worth mentioning that the above circuit is missing a
capacitor on the "Speaker out" line.

Good afternoon,
I¡¯m have Direwolf set up on my raspberry pi and it
will not tx audio. I have the PTT configured with a relay and
that will not fire either when I see the magenta text appear. It
IS receiving and decoding signals, and is indicating so on the
light I configured so I know GPIO is functional. Thoughts?
