RPi Direwolf packet station.
I've got Direwolf running on a Pi3b using a USB soundcard with good results.
Now I'd like to add TNC like functionality so that I can access the local packet services.
I had some great instructions on my Git hub journey using the Direwolf for APRS doc.
I'm looking for suggestions hoping the rest goes as well.

Re: Direwolf UDP socket input
This is direwolf on linux, the distro version for Ubuntu and Fedora (1.6) as well as built recently from dev branch (~1.7). I'm streaming gqrx to UDP port 7355 as in the tutorial. It seems to be working on the gqrx side as I can see the stream in netcat/netstat. And as mentioned, if I then pipe netcat into direwolf STDIN it is at least able to decode DTMF.
For direwolf I am just trying with the basic config for reading UDP socket: ADEVICE0 udp:7355 default
ARATE 48000
ACHANNELS 1
DTMF
I've also tried just running command-line `direwolf -n 1 -r 48000 -b 16 udp:7355`
As mentioned, adding -a10 to either of these doesn't show any output; it seems to hang on the recv() call in audio.c.

Direwolf UDP socket input
Hello all,
I'm trying to pipe gqrx to direwolf and not having luck with the udp:7355 socket input. It seems to hang on the recv() call; adding -a10 also gives no updates. I tried poking around the code a little but haven't found the issue yet. Any tips?
For now, a workaround is to use netcat to read the UDP port and then pipe that to direwolf STDIN.
Thanks!

Thanks Rob and Kevin for your replies. I immediately thought of Kevin's comment when I read Rob's reply, as I have been bit by that several times.
Your answers and some other things I ran into led me to first create .desktop files for direwolf and YAAC. Then I copied them into the .config/autostart folder and everything starts on boot and works great.
Thanks for your help,
Michael WA7SKG

Yes - that is VERY important when running from within a cron script.
Sorry for the confusion.? I copied a .desktop file and didn't think it through!

(btw, the suggestion is related to the ability to figure out the path, if it is being run as root in a crontab, or any of a number of other issues, the ~ path doesn't always point to where it 'should'. In root it points to /root/, and not to /home/<username>)

I believe most of the Linux distros have moved to using systemd startup files.?
?? It looks like you are trying to get Direwolf to run in the background (no display terminal).
?? Best to try and getting it working on boot within a terminal, then alter the startup to make it background.
?? I might suggest a less complicated startup script - no functions, just start direwolf with a defined configuration
Is your Quadra system running systemd?? If so, I suggest giving that a try.
?? If not,? you might want to create a more simplified script (as mentioned above)
Simplified script (assuming you don't need RTL_FM or other specialty application before Direwolf starts):
#! /usr/bin/env bash
/usr/local/bin/direwolf -c ~/direwolf/direwolf.conf
NOTE:? I have a direwolf directory in my home folder, where I keep different configuration files.? Just to explain the ~/direwolf/direwolf.conf
???????????? Also, removed any check if Direwolf is running.? You could add that later.

I have successfully (I think) installed direwolf on my Quadra. My issue now is starting it. If I try to run the startup script that came with the install it pops up a big error box that goes away before I can read it, then tells me it doesn't start with
========================================
quadra@inovato:~$ ./dw-start.sh
Direwolf in GUI mode start up
DISPLAY=:0
-----------------------
quadra@inovato:~$ ConfigBase::load: Unable to open /etc/xdg/terminator/config ([Errno 2] No such file or directory: '/etc/xdg/terminator/config')
quadra@inovato:~$
========================================
I have no idea where the stuff about "Unable to open /etc/xdg/terminator" is coming from. There is no reference to anything xdg in the script.
Most of the dw-start.sh script makes little sense to me.
I can go into the direwolf folder and simply type direwolf, and it seems to startup and run fine. But I have to leave a terminal window open to do this. Then I have to ctrl-C to stop it when I shut down the computer. Kind of a nuisance.
So, what is the best way to have direwolf start on boot?
I put the recommended crontab of
* * * * * /home/quadra/dw-start.sh >/dev/null 2>&1
but that does not seem to work. I am assuming it is due to the error shown above when I run dw-start.sh from the command line.
I appreciate your time.

Re: Cross Fix to ALSA-LIB and GPIO PTT issues
? Finally found the issue with using the GPIO pins on the Wandboard ARM machine. The GPIO pin I expected to use was muxed for use with a second SD drive. That they identified it in the diagrams for external use was the problem. Using a different external pin and re-designating it in the .conf file did the trick!? The 3.0v output drives an opto-isolator to run the PTT on a Yaesu FT-1800 with some current limiting resistors.
Curiously, I discovered I still have the KAM Plus and Yaesu FT270 I used in the 80's.

Re: New Quadra APRS Installation
Thanks for your reply, David.
The audio adapters I have look like a thumb drive with a couple jacks on the end. Other than that, I'll have to wait until I find them again to tell you more :-)
I've got two radio options for this project right now, a Radio Shack HTX-242 and an Icom IC-2350. Neither have data ports, so the connection will be via RJ-45 mic jack and external speaker jacks.
I found some info on using the CM108 devices. I just have to find the ones I have to figure out if they will work.
Thanks,
Michael WA7SKG

Hello Michael,
First, the audio interface. This is a no budget setup so something like Signalink is out of the question. I've got a couple cheap USB audio interfaces that have mic in and speaker out jacks. Will those work with direwolf? Can you give us some details of these "cheap devices"?? If they are what I think they are, they are CM108-based sound devices and should work for audio AND PTT with the addition of a few simple electronic components and some soldering.
Second is PTT. The Quadra has no I/O pins or serial port to trigger the PTT. The radio does not have VOX, which I would not use anyway. Can you tell us which radio you're planning on using?
Next, is direwolf usable with other digital modes than packet/APRS, like fldigi or WSJT-X? Direwolf only does AX.25 packet radio, AIS reception, and some DTMF stuff.? Fldigi, WSJT-X, etc are all entirely different programs supporting very different digital? modes.

Re: New Quadra APRS Installation
Direwolf has an option to use the GPIO of a CM108 sound card.? It requires taking the sound card apart and adding a resistor coming off a pin of the chip, and transistor to control the PTT.
Look up CM108 PTT and you should find some instructions.? I don't bother with SQL as the Direwolf is much better at checking if a signal is coming in.
Another option would be a cheaper interface than a SignaLink-USB.?
DINAH is at least half the price, and there may be others.

Re: Cross Fix to ALSA-LIB and GPIO PTT issues
Hi Dave, ? I went over the ptt.c file and compared the debug output I had for the Direwolf startup. There didn't seem to be any errors as it follows the libgpiod syntax completely. My guess right now is that the GPIO pins aren't identified in the dtb table for the kernel startup. I've translated three versions and see no reference in the dtc's for a simple GPIO I/O interface on the external pins. Most of the defined pins are used for chip-chip interaction. So now I have to "re-invent the wheel" and do a dtc blob for my GPIO-19 pin on gpio@209c000 (the first bank of GPIO modules) and a gpiopin@209c000 definition with the needed pinctrl and pin-gpios data. The iMX6 reference data from Technexion is forthcoming as I've hung on my access and login, TBD. Unfortunately the other iMX6 ARM users don't leave their dtc files lying around for me to plagiarize. Hasta, Dave KI6KPP
