Problem Receiving FLARM with Rosetta (in France)
« on: March 26, 2024, 04:35:21 pm »
Good evening
Is it possible to have an idea of how long it will take for the flarms to reappear on rosetta?
my latest version is 20230316 maybe I forgot to update...
Bonne soirée

AIUI it's not a Rosetta function - Rosetta gets FLARM traffic from the ATOM ground stations which do the decoding from FLARM and uplink as P3i(PilotAware protocol).

The ATOM stations are all automatically updated whenever PilotAware HQ releases new software to them - no one has to anything.

If you're not seeing FLARM on Rosetta, are you near ground stations?

Good evening
I fly in France and unfortunately there are very few ATOM stations, if any at all...
I think that the flarm signals are recovered via the OGN by the network of my GSM and transmitted by rs232 and wifi to the Dynon and aircrew screens.
In the last few days these signals have disappeared from the Rosetta, hence my question.

Rosetta doesn't use the OGN. Reasons are explained elsewhere. OGN derived FLARM signals aren't therefore a Rosetta issue.

There is a big issue with the OGN that until the stations are all manually updated, there will be a loss of functionality.

In order to receive FLARM via iGrid you'd need some way of injecting it into iGrid?

Hello
I'm still having problems receiving flarms with my rosetta, but the PAW tab has turned red with P3I red and the barometer red too (see attached photos).
I can't access the metars either, but there's a radar image on the radar page.
I'm in the 20230316 version and I've also tried the beta version 20240205 same thing ...
If you have any idea how to get the information .... thank you in advance

Red on P3i means no P3i is being received.

P3i will give you METARs, which is why there are no METARs.

Check the cable from the PAW to the P3i antenna. Are the antennas on the PAW itself, or are they internal/external ones? If the antenna is on the PAW, check it is seated properly.

Someone who knows the Rosetta better than I do will need to tell you how to check the P3i module itself...

Thank you Steveu for your feedback
it doesn't seem to come from the antenna,I crossed the 2 antennas and the large antenna the one for 869.5 mhz put in place of the 1090mhz allows to receive adsb the PAW tab remains red even with the small antenna connected to the 869.5 mhz
my skills stop here and indeed a help to see if the internal module PAW is functional would be welcome .... thank you for your help

It's not valid swap as the ADS-B signal is many, many times the size of the PAW one. You would probably get some ADS-B signal with no antenna at all.

However, my guess now is the P3i transceiver...

Time for a support email to PilotAware thremselves, or maybe they will post here.

Hi DY691,

While your antenna swap won't 'improve' reception, it does imply that there is no continuity issue with the longer 869.5MHz antenna - which should go back on the P3i connector.

I have just checked the PilotAware database and your aircraft (HexID 38533C) was certainly transmitting P3i on 20231123, 20231207 and 20240128 if that helps - all received at site LFLG2 at ranges up to 30Km. There are no more recent reports recorded, but that might just reflect some problems we have had with recent efforts to upgrade the PilotAware servers.

I see from the database, that apart from a couple of reports from Versoud in early 2021, all of your reported P3i transmissions are from LFLG2, which seems to be the only ATOM site you have been within range of. That of course reflects the lack of ATOM sites in France. I'm guessing therefore that in the past, most of the Flarm Traffic you have been receiving has been via SafeSky. That being the case, it might be in your interest to consider promoting further ATOM development in the areas you fly. If you are interested in helping to expand the network, please get in touch via atom@pilotaware.com and mention my name.

LFLG2 by the way is currently 'active' and running the updated 20240321 firmware, - which includes the updated Flarm Protocol, so you should see directly rebroadcast Flarm traffic, provided both it and yourself are in range of that site and provided the protocol has been updated in the relevant local Flarm Units.

If you continue to have problems please get back in touch.

Best Regards

Peter

Hello Peter
Thank you for your reply. I'm very pleased to learn that there is an ATOM station at LFLG.
Until recently I received the flarms via IGRID on my Dynon HDX wired link rs 232 and wifi on aircrew.
I don't use savefly in flight, it was just a check on the ground to see if it was working.
I have removed the Rosetta from my aircraft in order to check at home that it is working properly. I am at LFLE and there is a large glider centre 3km away,
 For the moment the weather doesn't allow us to see much traffic.
what I don't understand is that until now the P3I has been green
Is there a simple way of checking that the internal transmission module is working properly, given that my skills are limited?
I'll contact you on the ATOM address for the rest.
Thank you and good day
Guy

Bonne Apres-midi, Guy,

Hmm!

No PW  ATOM at LFLE unfortunately.

Looking again at your original post, together with the 'error' reports on the 'Logging Screen', and the fact that both the 'P3i' and the 'Barometer' are reporting as 'Unavailable' on the 'Home' screen, there could be a connection between these and your lack of Flarm uplinks via P3i - especially if you have been flying within range of LFLG.

The P3i transceiver and the barometric pressure cell are both mounted on the PilotAware 'Bridge' and if, for example, the unit isn't getting a '3D' GPS fix (which yours says it was - at least at the time you took the screenshots), or the GNSS altitude (GPS based altitude) doesn't match the reported barometric altitude within defined limits or no barometric altitude is available due for example to a software issue or a defective Baro Module - the Bridge won't transmit P3i, which in turn won't trigger the LFLG ATOM into 'Uplink Mode', so you won't get their Flarm data -except potentially via iGRID, though that still might not report if the system hasn't been able to calculate your altitude. That would certainly account for you not receiving Flarm Uplinks from LFLG.

Unfortunately, the only easy way to tell if your Rosetta is transmitting is to check it locally against another Pilotaware, or run it near a local ground station and get me to check the database afterwards to see if its transmissions have been received.

Although this could, as I have said, indicate a Bridge fault, the Bridge is usually extremely reliable and if it isn't working, it is much more likely to be due to a corruption of the software such as due to a defective microSD card, so before thinking about replacing the Bridge, it would be worth carrying out a few simple tests as follows...

Firstly, (with the unit powered down) check that the MicroSD card is fully seated in its slot (between the two antenna connectors). It is a simple slide out - and push carefully back in. If you can then connect your Rosetta to a monitor (or TV screen) via the Rosetta's HDMI socket, power up the Rosetta and check that it runs right through the 'boot' sequence without showing any obvious errors on the monitor. You don't need to read everything - just look for any obvious error messages. If the boot sequence gets to the point where the screen stops and reports 'Login' that is the sequence finished and the unit should now be running. You should now be able to 'log in' to the PAW WiFi and check if the P3i and Barometer are still reporting 'Unavailable' or if they have gone green.

If necessary repeat the test by rebooting the unit outside with a clear view of the sky so it can get a good view of GPS satellites -  then log in to the PAW WiFi with your phone or tablet and check again.

If there is still a problem, the next thing to try would be to load a new copy of the latest PAW software -available from https://pilotaware.lode.co.uk - and preferably loading it onto a new microSD card. If necessary, I can talk you through this process if we get to that point.

If the P3i and Barometer are still 'Unavailable' after loading new software, I would suggest returning your unit to PilotAware Support for full investigation, but try the simple tests first and let us see how we get on.

Best Regards

Peter

p.s. Let me know when you have read this, and I will split this discussion off into a new thread and leave Lee's original thread for issues directly related to the Flarm Protocol Update.
