GoFlight GF166 display blank - but only for PMDG737NGXu

Hi Steve, firstly, a happy new year to you and yours. I am loving your software with P3D v5.3HF2 but have recently encountered a strange problem I can't resolve.

I was flying the PMDG737-800 when the sim froze and I had to terminate the process. During this the display turned into a rainbow of strange colours but once closed the desktop colours were fine.

The next time I launched P3D with that aircraft the two GF166 units both display fine. But once the profile for the 737 has been loaded by GIT the COM unit was blank. The NAV one was fine.

If I press any of the buttons on the COM unit the display comes to life and is fine thereafter. I've looked through the various files GIT uses but I can't see anything different to both 166 unit settings.

This problem only happens with the PMDG. My other aircraft are fine.

Do you have any idea how this can be fixed please? Happy to provide files you require.
Cheers,
Ray (Cheshire, England)

  • I’ve finally resolved this but it was far from straightforward. It seems this release can support 0.025 frequencies on COM. I don’t really need this but thought the process might be editable. I opened GIT and selected the 166 tab. Then selected device 0 and chose enable.

    When I pressed COM a message appeared saying to press OK to revert to default settings. Having done so I discovered I now had Com frequencies to 0.025. But these weren’t being displayed properly and changing frequencies was a nightmare.

    I searched for an option to undo this action. Couldn’t find one. I had a backup from a few months back and checked what settings I had for GF166 in PMDG.xml. The entries were all blank and very different to the current PMDG.xml.

    Having made a copy of the current file I copied and pasted the GF166 values from my backed up file into the current one.

    That worked and I now have 0.05 frequency values and the GF166 COM display remains on when the PMDG737 has stabilised.

    It would have been a lot easier with instructions or an option to toggle between 0.025 and 0.05.

    Still no sign of Steve. I hope he’s okay.

  • Agreed. I will do that, but people were pressing me for a quick change as its now required for VATSIM.

    I'm OK. Took a long xmas break and then was sick for a while.

  • Hi Steve. It’s a relief to hear from you. I was hoping it was just a long holiday or perhaps illness and nothing more serious.

    I do have one issue when starting things manually as opposed to using SimStarterNG. That program is just a way of launching multiple executables to ease the workload.

    GIT connects fine and shows my current aircraft (so all programmed buttons and switches work) with SimStarterNG.

    However, if I start P3D manually, wait until the aircraft is at a parking position and then launch GIT I get the three green LEDs but the aircraft name just says Default and doesn’t display its name.

    The log just says Waiting for SimConnect…

    But the SimConnect LED is lit. Can you reproduce this? I can’t understand why it’s fine via SimStarterNG but not manually.
    Cheers,
    Ray (Cheshire, England)
  • Can you post your GIT log when this happens.

    Thx
    Steve
  • Will do Steve, thanks. I’ll do it tomorrow since it’s easily reproduced.
    Cheers,

  • Mornin' Steve.

    Here's the log. I started P3D manually with the PMDG737-800 selected at the Scenario screen. Then with P3D fully loaded I manually launched GIT.

    Then I launch SimStarterNG which loads P3D and other executables including GIT.

    GIT is set to be launched only when P3D is fully established in the sim. Here's that log. I should explain that I don't have P3Dv4 installed. A Registry entry is present to fool the installer for the Vertx DA62 which requires v4 to install.

    It's interesting there's no entry for the P3Dv5 SDK when launched manually. Sigificant?

  • You need the to be in the virtual cockpit before GIT will connect with the aircraft. The scenerio screen will not trigger the correct notification to GIT.

    Best wishes
    Steve
  • I am Steve. What made you think I wasn't? Just tried a manual start of GIT with the PC12. No go. GIT just says GENERIC for MODE and None for aircraft despite entries for the PC12 existing in Setttings.xml.

    Can you do a more detailed log showing why the aircraft is not being picked up? What's with the FSUIPC Connection Fail?

    Here's a log including a restart of GIT...

  • Okay Steve, I may have discovered the problem. Because I wanted to keep core 0 free for the OS I used core 6 for the MainThreadSchedule in the cfg file.

    I've now changed it back to 0 and launched P3D manually, waited until I was in the VC and then launched GIT.
    It connected first time and as I changed to two different aircraft it updated GIT.

    Looks like SimConnect doesn't agree with using that core 6.
    Cheers,
    Ray (Cheshire, England)
  • I spoke too soon Steve. Another manual start with the Lear 25 selected resulted in no connection. I logged SimConnect and the results are attached. Once the aircraft was loaded and I was inside the VC I started GIT. Can you deduce anything from the log?

    When I terminated P3D it hung so I had to terminate the process via Task Manager.
    Cheers,
    Ray (Cheshire, England)
  • There is a fix for FSUIPC in your account downloads. FSUIPC 64 bit never implemented a TCP/IP sockets server which GIT uses. The fix provides a 64bit server for FSUIPC.

    I will check at my end and see if I can replicate the issue.

    Best wishes
    Steve
  • Thanks Steve. I’ll install the fix tomorrow. Look forward to hearing how you got on. Would it help if I zipped up my DLL.xml and exe.xml files plus any others you feel might be relevant?

    I couldn’t get SODE to show a successful test from within P3D add-on menu. Then I discovered it was v1.80 which can cause issues with GSX. So I uninstalled it and reverted to 1.7.1 which is fine.

    Simconnect has always been a mystery to me. If ASP3D, ChasePlane both connect successfully it’s baffling why GIT won’t on a consistent level. Fine when launched by SimStarterNG but not when done manually.
    Cheers,
    Ray (Cheshire, England)
  • I extracted the files to the P3Dv5\Modules folder but the error message persisted. I then moved them to the folder containing FSUIPC6.dll and that fixed the FSUIPC problem.
    Cheers,
    Ray (Cheshire, England)
  • Hi Steve. Have you had any thoughts why GIT will not perform a handshake with my chosen aircraft in P3D when launched manually?

    It’s baffling why it fails to work when launched manually but is fine when launched via SimStarterNG.

    Another issue is P3D won’t close cleanly when I exit it on a manual start. No such problems via SimStarterNG. It has to be terminated via Task Manager. The P3D.cfg is identical for both situations.
    Cheers,
    Ray (Cheshire, England)
  • Yes, I think its when the sim is paused or the aircraft change triggers a pause and then the switch over is not detected. Can you confirm that's the case?
  • Steve, no, that not the situation. I manually launch P3D and at the scenario screen choose my aircraft. I have programmed actions for it created in GIT.

    I then hit OK and the sim continues loading and eventually is ready with my chosen aircraft on the runway.

    During that time the entries in add-ons.xml, exe.xml and dll.xml are loaded. These include ChasePlane but crucially not GIT.

    But the relevant GoFlight executable is loaded so my GF166s and MCP becomes alive. Frequencies are shown on both 166 units.

    I do nothing for 20-30 seconds to emulate how SimStarterNG behaves. GIT and other executables have not been started.

    I then launch GIT in admin mode and the three LEDs all turn to green. But crucially the aircraft name is not displayed so my switches are useless.

    It’s like SimConnect isn’t ready but the three LEDs suggest it is. The log says “Waiting for SimConnect…”. Why? It’s loaded according to the LEDs.

    There are three SimConnect versions. Which does GIT rely on?
    Cheers,
    Ray (Cheshire, England)
  • Steve,

    One thing that baffles me. If the green SimConnect LED is flashing green why does the log say "Waiting for SimConnect"?

    I have other programs that require SimConnect. SODE, ASP3D and ChasePlane. All are working correctly but GIT is the only one that isn't.

    Could you consider providing a facility to allow the user to manually select their aircraft rather than you detect it? Given all my GIT aircraft files are on the same computer I fail to understand why GIT cannot load the correct one.
    Cheers,
    Ray (Cheshire, England)
  • "But the relevant GoFlight executable is loaded so my GF166s and MCP becomes alive. Frequencies are shown on both 166 units."

    If GIT isn't running at the point, why are these lit up? The GIT module cannot do this that is loaded into P3D, so either GIT is running, or something else is driving them, like GoFlights own drivers maybe?
  • Ok, I can replicate what you are seeing. Its a very weird bug caused by the way you are running GIT. Usually GIT is started before P3D or during the scenerio screen and then the vehicle is selected etc.

    I will add it to my to do list to fix, but in the meantime, start GIT as above and all should be good.

    Also, address the issue I posted above and this may cause issues if two instances of software are trying to update the same hardware.

    Best wishes

    Hi Steve. Thanks for your replies. Being able to reproduce the problem is great. I don’t have my computer on at present but from memory the following files are loaded via dll.xml and exe.xml from the ones in myname\appdata\roaming\LM\Prepar3Dv5…

    GIT interface.dll and GoFlightP3Dv4.exe.

    I’m guessing the first is yours to communicate between P3D and GIT and the second is by GoFlight to provide a link for their hardware.

    It’s interesting you say to launch GIT before P3D. I will test that tomorrow and report back. Thanks for your ongoing support. :)

    Because I have a mixture of commands via GIT and others that use standard GoFlight commands I presumably need both GIT and GoFlight drivers running.
    Cheers,

  • Hi Steve,

    Here's the results of this morning's tests.

    1) I started GIT first.
    2) Then started P3D.

    GIT went through various LED stages but when I selected the Learjet in the Scenario window GIT loaded the aircraft profile.

    When P3D was fully running the engines were running and my switch settings weren't read. I checked SODE and no connection to SimConnect could be established. ChasePlane couldn't load my camera settings and ASP3D could not connect to P3D.

    So that sequence was not successful. When I exited P3D it didn't close fully and had to be "end tasked" in Task Manager.

    Next I started P3D and at the Scenario screen I started GIT. When I selected the Lear GIT immediately loaded the profile. When P3D was fully loaded SODE was okay and so was ChasePlane. ASP3D made the connection as well. When I exited P3D it closed correctly.

    So the sequence seems to be to delay loading GIT until the scenario screen is present. Hopefully you can resolve the bug so GIT can be loaded at any time. As things stand I can't load it via SimStarterNG and will have to load it manually at the correct time.

    Cheers,
    Ray (Cheshire, England)
  • Hi Steve, whilst I can workaround this problem by starting GIT manually at the Scenario screen a permanent resolution would be preferred allowing me to start GIT automatically via SimStarterNG.
    Cheers,
    Ray (Cheshire, England)
  • I'm working on this amongst some other things that people need/asked for.

    Steve
  • Thanks Steve. I'm never sure if you have a daytime job taking up your time or still recovering from illness.
    I'll bide my time. :)
    Cheers,
    Ray (Cheshire, England)
  • Hi Steve. How is the update going? Ready for release yet?
    Cheers,
    Ray (Cheshire, England)
  • No. I have had to delay it, while I work on updating the website and shop to the latest versions (offline of course) because support is ceasing soon for the versions I use. Its turned out to be a nightmare, but nearly there.

    Best wishes
    Steve
  • Understood Steve. Thanks for letting me know. :)
    Cheers,
    Ray (Cheshire, England)
  • Hi Steve. Are you getting close to releasing a new version that will allow me to launch GIT via SimStarterNG instead of manually?
    Cheers,
    Ray (Cheshire, England)
  • Are you there @admin_pps ?
    Cheers,
    Ray (Cheshire, England)
  • I am now. I will start working on it again, been really ill for a while.
