P3D v4.4 - FSUIPC5 and Ivap Mode C

Recommended Posts

Hallo, 

After several similar issues reported FSX/FSUIPC4 I m facing the same in P3D v4. Communication between MASTER and CLIENT (IVAP 2.0.2) use Offset $7B91 for change Ivap squawk box from STNBY to MODE C which is not working. Other offsets are linked and functional, so I guess there is no issue with firewall or any data flow restrictions

Reading several articles tried to implemented fixes in FSUIPC.ini like NoActionOn7B91=Yes. Unfortunately still without success.

Installed / FSUIPC5 5.14, WideFs 7.15, P3D v4.4

Hardware in cockpit / ATC Transporder by Opencockpit, SIOC 6

After 2 weeks of investigation I m in the end of ideas. No problem occurs in FSX and FSUIPC used several years before my change to P3D... 

Thank you very much for the direction and any support

Best regards, Roman

I don't know IVap at all I'm afraid, but there's no change whatsoever in what FSUIPC does for anything involving offset 7B91.

Is that way of operating the Transponder mode supported by iVap, for P3D4? It was a Squawkbo thing.

Is iVap interfacing to FSUIPC?  Ifso , is it an EXE or a DLL? Does it say it is connecting?

Or is it using the SimConnect Client data named "Squawkbox Data"?  Is iVap using that?

Use FSUIPC's logging to show changes in 7B91 -- Logging tab, right-hand side. enter it there as yype U8 and check "normal log" before. Then the log will show what it does. Does it changes correctly?

Then you will probably need iVap's help.

Pete
