A useful feature of Direwolf is that it exposes an AGWPE port on your local network that you can connect to across your local network. I use this feature to run an APRS app on my laptop elsewhere in the house with Direwolf running on a Raspberry Pi beside my 2m radio in my office upstairs.
With the YACC APRS app, this is as easy as adding an AGWPE port in the app and pointing it to the IP and 8000 port of the Raspberry Pi where Direwolf is running:
This is a continuation of part 1 here. To summarize the required steps to setup ax25 and Direwolf for software based packet radio, here’s the minimum steps need to get up and running:
Configure ~/direwolf.conf – change ADEVICE to refer to the device number from the previous step:, and then set your call sign:
ADEVICE plughw:2,0
MYCALL KK6DCT-5
Run alsamixer, select your soundcard attached to your radio, and make sure playback and capture sound levels are around 70% and not muted:
Install ax25 apps and tools:
sudo apt-get install libax25 ax25-apps ax25-tools
Add 1 line in /etc/ax25/axports – the number in the first column is the port number, you’ll need this in the next steps:
1 KK6DCT-1 1200 255 2 2m packet
Run:
direwolf -t 0 -p
Look for the last line for /dev/pts:
Ready to accept KISS client application on port 8001 ...
Virtual KISS TNC is available on /dev/pts/0
WARNING - Dire Wolf will hang eventually if nothing is reading from it.
Created symlink /tmp/kisstnc -> /dev/pts/0
Run kissattach:
sudo kissattach [/dev/pts/value here] [ax25 port value here]
e.g.
sudo kissattach /dev/pts/0 1
You should see:
AX.25 port 1 bound to device ax0
Now you’ll set to use the ax tools to connect to other nodes, for example, run:
