So I have a pi zero W that I loaded with raspbian and then installed the piaware packages to. It will connect to flightaware but will only be up for a few seconds then be down for a few minutes. This had been going on since setup. It will also trigger the automatic 12 hr downtime warning once every other day. At which point I reboot and it continues to work for a few seconds then down for a few minutes. Anyone have any ideas on how to get this to be more reliable?
Most of these issues turn out to be a power supply problem. Try a different one and a different cable as well.
Maybe try a USB phone charger?
(might also be the OTG USB cable being not too good at supplying the dongle with power, i suppose you could try connecting the dongle to an USB hub and the hub to the OTG cable)
Yeah that’s typical for power supply problems, maybe your micro-USB cable or the OTG USB-cable aren’t capable.
I would recommend either the Canakit power supply or “Official Raspberry Pi 3B+ power supply”
They provide 5.2 V instead of 5 V and often solve those problems.
If you want a bandaid that will automatically restart dump1090-fa you can try the following script:
#!/bin/bash
exec &>>/tmp/wedge
sleep 20
journalctl -b -0 -f -n0 | grep 'No data received from the SDR for a long time' --line-buffered | {
while read line
do
date
systemctl kill -s 9 dump1090-fa
sleep .3
systemctl restart dump1090-fa
done
}
First you open a new textfile with an editor, paste the above script, save and exit
nano /home/pi/wedge.sh
COPY/PASTE
CTRL-O
press enter
CTRL-X
sudo crontab -e
Add the following line
@reboot /bin/bash /home/pi/wedge.sh
save and exit.
After the next reboot dump1090-fa will be automatically killed and restarted after wedging.

Those are single quotation marks but those with direction, not even simple single quotation marks
Depending on localisation/language on a mobile phone there will be different symbols on the keyboard.
Anyway make sure you didn’t miss my post above yours just in case you want to use that workaround.
