What is your setup? (What kind of Pi, how did you install the packages, what packages did you install, what versions?)


raspberry pi2 +; and the packages download here

tried to update dump1090 but it show’s me version 1.09…

not familiar with Linux/Raspian so if you can tell me how to read the version’s installed

The daemon author would be the best to help, but I’ll see if I can give you some help. Can you SSH into the pi? \

If you can, try running ‘sudo piaware-config -status’ and ‘sudo piaware-config -show’ but delete out your password.

It looks like there is a problem in the piaware package which is where fa-mlat-client is called from. Also if you can run ‘ps aux |grep fa-mlat’ and see what the ‘–results’ line looks like? Mine is as follows:

/usr/bin/python3 /usr/sbin/fa-mlat-client --input-connect localhost:30005 --results beast,connect,localhost:30004 --udp-transport

Have you run piaware-config -mlatResultsFormat in the past? That’s the only way I could think of this breaking.

Try: sudo piaware-config -mlatResultsFormat default

DONE and after restart it works…hope no changes follows :stuck_out_tongue:
thx for help
