Receive no traffic #1

Closed ubx closed 3 years ago

ubx commented 3 years ago

Installed version 0.0.7 following the Easy Installation instruction. I have a FLARM (version 7.01) and a OGNTP device nearby:

No traffic received
Receive periodic UDP debugging messages (in my case over address 192.168.1.200)

BTW very interesting project!

Hi Andreas!

You need GPS fix.In picture, i see GNSS zero. Wait for gps fix, gnss should show you the number of satellites.Then, decoding packets are possible and the groundstation is registering in ogn network.

At this point, you should see aprs messages in port 12000. Please let me know, if it works or not!

Thanks! Manu

Hi Andreas!

If i take a look at glider radar, i can see your station with last forwarded aircraft. Is your problem solved?

ubx commented 3 years ago

Hi Manu

I moved the ground station (Walpwil-M) outside and now it sees 7 satellites. I also turned off my other Raspi ground station (Walpwil), to avoid confusion. But still not traffic forwarded to the ogn network.

Hi Andreas!

Please test to change "Ignore track bit" and "Ignore stealth bit" to true.

Manu

ubx commented 3 years ago

Done, still not traffic forwarded.

roema commented 3 years ago

Your ogn or flarm transponder has gps? The second protocol is currently not supported. Only the first protocol is decoded.

roema commented 3 years ago

Ok, no i can see you traffic. But there is a bug in ARPS coding.

Error, This is not a valid APRS packet: FLRC424E4>APRS,qAS,Walpwil-M:/104147h4703.70N00713.70En000/000/A=001555 !W94! id3EC424E4 +000fpm +0.0rot 82.00dB 0e -0.0kH

I will fix this today evening.

Thanks Manu

FYI on UDP debugging I can now see these messages:

Hi Manu

Updated to the new firmware. No periodic UDP debugging messages anymore. Timestamp field doesn't change.

Have found a bug in aprs symbol table. Can you test this image?

Hallo Manu

Ich bin im Moment nicht im "Labor". Test heute Abend wieder.

version0.0.8 should fix this problem

ubx commented 3 years ago

Hi Manu

With the latest image it works! But I'm a little confused. I thought the legacy protocol is for FLARM only. If I set Protocol 1 to Legacy then both OGNTP and FLARM stations are forwarded to the ogn network.

Just in case: FLARM id: DD8C98 OGN id: C424E4

Andreas

roema commented 3 years ago

Hi Andreas!

C42464 is the id from your ogn basestation and used as callsign. If you see a packet like

Walpwil-M>APRS,TCPIP*,qAC,C42464:/203741h4703.67NI00713.70E&/A=001541
Walpwil-M>APRS,TCPIP*,qAC,C42464:/205125h4703.67NI00713.70E&/A=001541
Walpwil-M>APRS,TCPIP*,qAC,C42464:>205125h 0.0.8_ESP32 3.93V

its not an aircraft packet, that are status packets.

Are you sure that your station is sending OGNTP packets? If you've set legacy as protocol-1, that's actually impossible.

I will close the issue as the original problem has been resolved. However, I noticed a second problem in the APRS keepalive package which is fixed with version 0.0.9.

Let me know if your problem still exists !

Manu

ubx commented 3 years ago

Hi Manu

You're right, I completely forgot, the OGN's device protocol was set to legacy. It works as expected! Tested with version 0.0.9.
