Issue

Hello Wingflex team. I am using Xplane 11. I only use Toliss airbus A320 and A321 (with the ceo and NEO versions, latest updates). Like mentioned above, none of the v3.x.x.x versions of the wingflex software wings-bridge are working with XP11. When starting the application it does nothing, it even does not create a folder in the plugin folder of XP11. Bridge V2.5.1.13 is working in XP11 although with some issues. The RMP cube in the combo works but it sometimes disconnects and when I push buttons on the RMP it does nothing. After several pushes it wakes up again but after a bit it goes back sleeping again (A320 and A321). This happens with all the cubes in the stand, so also with the EFIS and FCU. They freeze, not all at the same time with sometimes the backlighting still working on the cube and sometimes the backlighting goes off but if you turn a knob or push a button it does nothing and after some time, sometimes 30 sec or more it works again. It happens during the whole flight about every 5 minutes, I also found a strange issue with the RMP in the A321. The knobs (TCAS) (Stby/auto/on) and (stby/ta/tara) are switched (dataref?). If i turn the knob on the RMP cube (stby/auto/on) it triggers and moves the (stby/ta/tara) switch in the sim and the same happens when i turn the knob on the RMP cube (stby/ta/tara) it moves the (stby/auto/on) switch in the simulator. I can't move the switch further to the right in the simulator(stby/ta/tara) because it returns to the position that the RMP cube gives. I use the EFIS FCU and RMP in the cube stand. I also use the OVH and the MCDU. On the OVH the 'align' text is not written when starting the ADIRS, there is written 'OFF' until the ADIRS are aligned.

Steps to Reproduce

I re installed the wings-bridge V2.5.1.3. I opened wings-bridge to test the equipment and even there the cubes don't respond with some time in between. Sometimes they freeze like in the simulator. No response at all when pushing/pulling or turning a knob and after +- 30 seconds, after that they respond for a little time and then it stops again. This is with the EFIS FCU and RMP, not with the mcdu and OVH panel.

Expected Result

I expect that the cubes should work without freezing. I don't know if it are the cubes or if it is the stand that maybe has a malfunction with the 3 usb wires

Actual Result

The result is that there could be or a software problem or a hardware problem within the cube stand electronics.

Workaround

No confirmed workaround at this time.

Notes

If I look in the Log.txt from Xplane 11, I can see the following line. I don't know if this is relevant information. For your information, i updated the C++ and followed the steps on the wingflex site.
Hereby the line of the log.txt:
XPluginReceiveMessage : Error Code = 127 : Kan opgegeven procedure niet vinden.(can't find the given procedure)
Loaded: D:\X-Plane 11/Resources/plugins/Wings-Bridge/win.xpl (com.wingflexsim.www).

Thank you for reporting. We will review this on Monday.

Hello Wingflex team,

Here is an update on the issue I mentioned above. Still using V2.5.1.3. V3.x.x.x not working in Xplane 11.
The USB cable from the Cube Stand was connected to another USB cable (an extension cable), which in turn was connected to the PC. After doing some research, I connected the USB cable from the Cube Stand directly to a USB port on the PC. I then opened the Wings-Bridge app, and the Cube Stand, along with the EFIS, FCU and RMP, worked without any issues. I suspect the problem lay with the USB extension cable. Once this was removed and the Cube Stand was connected directly to the PC, the problem was sorted. I also completed a flight without any issues. This was with the Toliss A320.
I’ll try it again with the Toliss A321 to see if the problem has been resolved. I’ll also check on the A321 whether the buttons (stby/auto/on) and (stby/re/tara) are working correctly. After this test I will let you know.
A new folder has been added to the X-Plane 11 plugin folder: WFXplane alongside the folder wings-bridge that was already there.
The only issue still there is on the overhead ADIRS where the buttons read "OFF" when the ADIRS are aligning, but i suppose this is already a known issue.
However, the log.txt file for X-Plane 11 still contains this error message, as mentioned above:
XPluginReceiveMessage : Error Code = 127 : Cannot find the specified procedure.
Loaded: D:\X-Plane 11/Resources/plugins/Wings-Bridge/win.xpl (com.wingflexsim.www).

My apologies for the inconvenience
Kind Regards,

Hello Wingflex team,

I did the test with the Toliss A321 Xplane 11 with bridge version 2.5.1.3. The overhead works perfectly, the MCDU works perfectly. The combo stand with the EFIS, FCU and RMP are working normal EXCEPT the following:

If you turn the physical TCAS switch (STBY/TA/TARA), the bridge controls the transponder functions in the aircraft.
If you turn the physical transponder switch (STBY/AUTO/ON), the bridge controls the TCAS functions in the aircraft.

If the team could have a solution to this little issue, it would be wonderful.
Thanks in advance,

Stef

Hello Wingflex team,

Here is an update regarding the issues with the ATC and TCAS buttons on the RMP.
As previously mentioned, the ATC button on the RMP controls the TCAS in the Toliss A321 in X-Plane 11, and the TCAS button on the RMP controls the ATC button in the Toliss A321 in X-Plane 11.
After a three-hour discussion with an AI programme, a solution was found and a Lua script was created to resolve the issue, ensuring that the ATC and TCAS buttons on the RMP control the correct corresponding virtual buttons in the Toliss A321 and also set them to the correct positions
This works with WingBridge 2.5.1.13 in X-Plane 11 and only with the Toliss A321; the Toliss A320 works correctly.
As the latest version of WingBridge, 3.1.0.2, does not work – it only recognises X-Plane and not the Toliss aircraft – I am continuing to use version 2.5.1.3.
If you are interested in the Lua script to potentially analyse the error, I would be happy to share it with you.
Kind regards,
Stef
