Planes but not feeding

Indeed. That thread has been an attractive nuisance for anybody trying to use an AirSpy.

For the most recent version (v1.37) of airspy_adsb very few commands are needed to feed ADS-B to a working Piaware[1].

This is all that is needed:

/home/pi/airspy/airspy_adsb -c (your_receiver_ip):30104:Beast -g 13 -x -f 1 &

Add in “-b” if you need bias-t. Adjust “-g” (gain) as needed. Add “-p” (bit packing) if needed. I believe that “-f” defaults to 1 anyway.

It’s also helpful to add in a “-v” and leave off the background “&” while debugging. Control-C will stop the program under that mode.

Ignore and skip any “-l” or “-m” (MLAT) commands. Piaware will handle the MLAT.

[1] A working piaware is defined as:

netstat -a | grep 30104

should produce a LISTEN line like this:

tcp 0 0 0.0.0.0:30104 0.0.0.0:* LISTEN

In fact, I would suggest solving any Piaware issues with not listening on port 30104 before trying anything with airspy_adsb.
