Setting QNH with Mobiflight

[michael1508]

Hi guys,

have connected encoder to mobiflight to set QNH.
Encoder does work for com frequency, but not for QNH values (datapipe function).

Mobiflight debug tracker is indicating the impuls for left/right, but value stays unchanged.
I have entered $-1 or +1 for left/right. Is there any other aspect, I need to consider?

Thanks,
Michael

Nobody with a hint?

You need to input the absolute value, not a +/- 1 request (to circumvent FSUIPC high latency), and keep the value in memory in your own code.

What do you mean with "own code"?
I am using Mobiflight. There's only the option to enter what to do with the current value on turning the encoder.

I have no clue at what mobiflight even is. The way the QNH settings work using FSUIPC datapipe will not change anyway. What is required is sending an absolute QNH setting (1023mb or 29.84 inhg etc...). This means you cannot send +1/-1 using the datapipe offset.

You can however do that using the 78EB offset, read the FSUIPC offset doc provided with my software for further info.

Jeehell, thanks for your help.

I tried to send the value 25 for Cpt QNH decrease at the above offset. But in this case, Mobiflight shows an error message (wrong format). I guess, this I have to clarify in the Mobiflight forum....

Or anybody here with Mobiflight experience?

Thanks!
Michael

The Offset 78EB solution is working now.

There was a bug in the Mobiflight Software, which has now been fixed by the developer.

Thanks everyone!
