Need help debugging a controller issue

[aurel42]

Hello there!

I use this fancy force-feedback yoke (Brunner CLS-E NG) with P3D v4.5 and the latest FSUIPC. The yoke needs a software ("CLS2Sim") which is constantly running to talk to P3D.

When this software is running and I'm using an aircraft that has a Flight Director that can be toggled on and off (examples: Aerosoft Twotter, xTreme Prototypes LJ25D, RealAir Turbine Duke), the FD is constantly toggled on, off, on, off, about once per second. When I "disconnect" the Brunner software from the sim, this behaviour stops immediately. I reconnect the software and it starts again.

I am not sure whether it is a button, keyboard, or SimConnect event that toggles the FD. I don't have the FD control assigned in FSUIPC, so I suspect it's a SimConnect event, but I cannot be certain.

Is it possible (and, if so, how) to debug the issue using the FSUIPC logging feature, so I can tell the software developer what exactly is happening on my system?

I appreciate any advice!

Cheers,
Marc

Hi,

as far as I know Brunner uses SimConnect only you can check with Events from Logging tab. IPC writes would only show if they use FSUIPC. You can also use P3D SimConnect logging, described in their manual how to setup.

Thank you very much, Thomas! I ended up with a file with over half a million lines of raw SimConnect log data.

Just glancing over the data, I found this when (and only when) the CLS2Sim software was "connected":

< 494.85144 [63] >>>>>  EXCEPTION=2, SendID=199484, Index=0  <<<<<  Unrecognized Data Received. [63, 199484]

While this seems fishy, it doesn't seem to be related to my problem. But it could be an indicator that Brunner's SimConnect code has... well... issues. 😄

I think I also found the actual culprit:

Line 14377: > 72.63441 [63, 19]MapClientEventToSimEvent:EventID=9002, EventName="TOGGLE_FLIGHT_DIRECTOR"
Line 14378: > 72.63443 [63, 20]AddClientEventToNotificationGroup:GroupID=2, EventID=9002, bMaskable=0
Line 318595: > 324.31639 [63, 119422]TransmitClientEvent:ObjectID=0, EventID=9002, dwData=1, GroupID=2, Flags=0
Line 319814: > 325.31732 [63, 119898]TransmitClientEvent:ObjectID=0, EventID=9002, dwData=1, GroupID=2, Flags=0
Line 321003: > 326.31440 [63, 120369]TransmitClientEvent:ObjectID=0, EventID=9002, dwData=1, GroupID=2, Flags=0
Line 322239: > 327.31735 [63, 120845]TransmitClientEvent:ObjectID=0, EventID=9002, dwData=1, GroupID=2, Flags=0
Line 323525: > 328.33978 [63, 121321]TransmitClientEvent:ObjectID=0, EventID=9002, dwData=1, GroupID=2, Flags=0
...

This matches exactly what I'm seeing: about once per second the FD is toggled off. "Client" 63 is called "SimConnectWrapper" and it's clearly the CLS2Sim software. Armed with this, maybe I can get Brunner to finally acknowledge and maybe even fix the issue.

FSUIPC really is the swiss army knife of ESP flight simming.

Thanks again,
Marc

Hi,

seems an unwanted line of code has been left in their program. At least you know and can let them know to asap fix it.

Wish me luck. :) In the past couple of weeks I provided detailed information (of course including which version of P3D I'm using) and description, examples, CLS2Sim profiles, even video of the issue, and the only response I got was that they can't reproduce it in X-Plane (sic!). I can't even…
