Hello,
First of all, thank you for DigiPi — excellent project.
I am currently running DigiPi on Raspberry Pi 4 with an RTL-SDR Blog V4 dongle.
RTL-SDR reception and Direwolf decoding are working correctly.
Digipeater and IGate are functioning properly.
However, when using RTL-SDR (via rtl_fm pipe or direct RTL mode), the OLED display no longer shows received callsigns or packet activity.
direwatch.py is running and reading /run/direwolf.log, but no APRS packets appear on the display, even though Direwolf clearly decodes them in the console.
Previously, when using a radio + USB soundcard, OLED display worked perfectly.
Could you please advise the correct way to integrate RTL-SDR reception with DigiPi so that OLED packet display works as expected?
Thank you very much for your support.
73,

rtl-sdr isn't explicitly supported on DigiPi (not an audio device), but you can
kind of get rtl-fm and direwatch.py to work together with these commands,
rtl_fm -s 22050 -g 49 -f 144.39M 2> /dev/null | direwolf -d o -t 0 -r 22050 - > direwolf.log &
./direwatch.py -o -l direwolf.log -t "APRS"
more info at my direwatch github page: https://github.com/craigerl/direwatch
best,
