Technical Support / Re: Rosetta not working after software upgrade

Good news!  I bought a replacement 1090 dongle (Nooelec NESDR Nano 2 from Amazon next day delivery), and that does seem to have fixed the problem.  The 1090 status is now mostly green but occasionally orange as expected.  The power status is usually "volt=OK" and "Thro=OK" although I have seen "Warning" a couple of times.  I have tried the old and the new software and both seem the same.

The only odd thing is that when I first tried it, the GPS status seemed stuck on orange for at least 10 mins even though it could see satellites:
"RX=1455(+27) Fix="No fix" Mode="Not Available" Sat=0(use)/14(view)".  It did this over several reboots.  I then tried removing the 1090 dongle and the GPS then worked fine, and it was still fine when I put the new 1090 dongle back in (powering off each time).  Of course I had to remove the GPS dongle to get the 1090 dongle in and out so it could be just that it wasn't quite in right, although it seemed quite secure.

Anyway, it seems to be working solidly now, I just need to try it back in the aircraft next time I am able to fly.

Thanks for all your help.  I've certainly learned a few things about how Pilotaware works.

Hi Alan,

I think you may be on to something.  Yes the 1090 dongle is certainly plugged in. I had assumed that the 1090 red status was due to there being no traffic around to detect because of lockdown.  If the 1090 dongle was working OK but there was no traffic for it to detect, what status would you expect to see? Also, would it cause any harm to the dongle if I had powered it on with no antenna connected?

Today, I first tried the new Powercore 1300 battery pack, and with the old software (20190621) I saw the same behaviour.  Usually "Volt=Warning" and sometimes "Volt=Error", and it would eventually go to green GPS status but would take several minutes.  The 1090 satus was always red "Unavailable", as it has been throughout this testing.

After seeing your messgae, I tried unplugging the 1090 dongle, and then it got green GPS status much quicker, within about 1 minute, and always showed "Volt=OK".  After verifying this a few times I tried going back to the new software (20201101), still with the 1090 dongle unplugged, and that also worked fine with GPS green within 1 minute and Volt=OK.  Again I verified this a few times. 

When I plugged the 1090 dongle back in, with the new software, the status was solid "Volt=Error" although it did manage to get green GPS status, which it didn't yesterday.  I don't know why this is different from yesterday as I am back to the exact same configration, and I have tried it with both powercore battery packs.

Anyway it does look as if the 1090 dongle is causing extra current drain whch is giving me "Volt=Warning" with the old software and "Volt=Error" with the new software.  I don't know if this is because the dongle is faulty or just that the whole system is too marginal.  The best way to determine this would be to try a new 1090 dongle.  Do you know how I can get a replacement for that?

Thanks,

Martin.

Thanks again for the help.   I have tried reverting to the 20190621 version which is what I was using before.  With that version it appears to be working fine, albeit with a "Voltage=Warning" status.  I have attached a screenshot of the status.  This is with with Anker Powercore 20100 (with an LED light to stop it switching off), and the almost new 20awg USB cable (no no problems with a worn out cable).  I will try both versions of software with the new Anker Powercore 13000 when it arrives tomorrow, which I think will be a perfect "approved" setup.

However it is clear that exactly the same setup works with the old software but not with the latest. So the new software must be more demanding on the power supply than the old version.  If no one else is reporting these problems is it possible that my Rosetta is for some reason more power hungry that others?

If all else fails I will just stick with the old software which had been working fine, but it is a shame if I can't take advantage of any new features.

Martin.

Thanks for the quick replies.  I should have noticed the "Volt=Error" and "Thro=Throttled" status messages.  The unit is normally powered from a USB supply wired into the aircraft's 14V supply, using the original 20awg USB cable supplied when I bought it.  However that photo was taken after I had landed with the engine stopped so it was running off the aircraft battery which only give 12V compared to 14V when the alternator is running.  I don't normally use the PAW in that way and the problem showed up with the alternator running to.  I do sometimes see "Volt=Warning" but that does has never caused this problem before.

Anyway, I have now removed the unit from the aircraft.  I am running it with an Anker Powercore 20100 power bank.  This was the recommended power bank when I bought it, but that was just at the time that there started to be problems with it powering off when only the Rosetta is plugged into it.  I work around that issue by having an LED light plugged into the other USB socket which stops it switching off.  I am using a 1m Juicebitz 20awg USB cable.  I have also now replaced the original inernal GPS dongle and antennas, rather than the external ones as installed in the aircraft. With that setup it shows exactly the same behaviour.  With that power configuration I am also seet "Volt=Error" which sometimes reverts to "Volt=Warning" and on one occasion it stayed in "Warning" state long enough for the GPS to start working after it had been powered on for at least 15 mins.

So it does seem that the problem is casued by the voltage error, but this is now on a recommended power setup, which used to work fine.  So it seems very likely to me that the new software has made it even more sensitive to supply issues.  Am I really the only person to have experienced this?  I have ordered an Anker Powercore 13000 which is your current recommendation so I will see if that makes any difference and let you know.

I have also tried re-formatting the micro SD card and re-installing the latest software from scratch as suggested.  That made no difference.

What would really like is a way to downgrade to the previous version of software.  Is there really no way to do that?

Thanks,

I have had pilotaware rosetta in my aircraft semi-installed and working ok for over a year.  Have not been flying much due to Covid restrictions, but on Dec-30-2020 I flew and it all worked ok.  On 5-Jan-21 I updated the firmware to 20201101 using the PilotAware Updater App and the update seemed to work ok, but I did not fly or test it properly on that day.  Today (12-Feb-2021) I went flying and PilotAware was not working.  Connecting from Sky Demon it was stuck on "Looking for Satellites".  Looking at the PilotAware homepage is sais "GPS unavailable" (photo attached).  I am sure that this is related to the software update but I can't find a way to downgrade to the previous software to check.  Any ideas?
