I have 2 Pi’s (version 3B) running the ADS-B Receiver Project setup / scrips. One aerial (after about 15m cable) goes into a habamp / filter and then gets split and goes to an original orange dongle on one Pi and a newer blue dangle on the other Pi.
Both of the Pi’s are powered by POE, for the orange dongle one I have a POE splitter at the Pi end, and the other end goes into the POE switch. For the blue dongle one I have a TPlink POE injector at the switch end (from a non POE port) and then a TPLink splitter at the Pi end.
Everything has been working fine for 5 months (and before that about 3 years before I was off-line for about 6 months due to a house move).
Anyway, the other week I got a email from Flight Aware saying that my system had been off-line for 6 hours. Looking into it and it turns out that the Blue dongle Pi was off. I tried power cycling it, and it came back up, but after a while it want off again. Power cycled it again and it came back up, I then looked at the performance graphs and saw that for about the previous week there had been may times when data was unavailable (but not longer then 6 hours so hence no email from Flight aware). I check all the cables etc and all looked ok, so I got a spare 5v power supply and managed to connect it up to the blue dongle Pi, and it booted up, and worked ok for several days. Assuming that something may have gone wrong with the TPlink injector / splitter (and now having a spare POE port) I brought a similar POE splinter to the one powering the other Pi.
When it arrived I powered down the Pi, and connected up the new splitter, the lights on the RJ45 end lit up to show power, but as soon as I plugged the micro usb connection into the Pi the lights dimmed / went off, and the Pi failed to power up. I decided to try again but with the blue dongle disconnected, and this time the Pi powered up, but once it was up as soon as I plugged the blue dongle back in it crashed with a lack of power. I also tried with the Blue dongle plugged in, but the aerial lead disconnected, and that powered up, but crashed as soon as the aerial was connected back in.
The other Pi works ok on a POE splitter and this Pi worked fine on the TPLink injector / splitter uptill 2 weeks ago, and with nothing else changing I am wondering if something has gone a bit wrong with the Blue dongle, and is maybe causing a power overload. The Pi / Dongle works fine with a proper power adapter, just not over (2 types) of POE.
Anyone else experience anything like this or a faulty (blue) dongle.
While I’m here, as I said I am running the ADS-B Receiver Project setup / scrips, however not sure that is the best solution now. I upgraded to the latest version when I re-set up my systems 5 months ago, but I notice that https://www.adsbreceiver.net/ doesn’t work, and the project scripts don’t seem to have been updated in quite a while.
I liked the extra graphs / stats and web page that the Receiver Project provided, as well as being able to run the script to find the best gain. Am I correct in that it seems that the performance graphs / stats can now be added to the standard Pi Aware build, and also a “improved” web page. If so, is it worth sticking with the Receiver Project setup, or re-freshing with the latest Pi Aware build and trying to add the graphs and web site.
With Thanks, Ian.
