FBW A320 & WebSocketServer LVAR conflict

[Toedde]

Hello John,

since my update to 7.501 i have an issue with the FBW Remote Tool that comes with a myOffsets.txt file. It says that "The Server reported a problem:
Any Uses the legacy LVAR Interface. This command is not supported."

Any is the WebSocketsServer, right?

Class Instance ID: 0
WebSockets Server:
Info:
Connected to: Any
Connection via Wideclient.exe? : No
FSUIPC Version 7.501

ws://localhost:2048/fsuipc/

Due to the 20 KB limitation i am unable to add the FSUIPC7.log

Can you give me a hint where else to look to solve this error?

Upload limits are restricted for new uses - your limit will increase the more you post. You can compress the file, but if still to large you will have to use one of the (free) file transfer services, such as https://filetransfer.io/.

Sorry, but I have no idea what that is - are you actually using the WebSocketServer? Does  the FBW Remote Tool use the WebSocketServer?

This is confusing...the myOffsets.txt file is for adding simvars to offsets, not lvars.  And I have no idea what the "legacy LVAR Interface" is. As this is from the "FBW Remote Tool ", you should contact them to see what this means and what you need to do to correct this.

Please post/update here if/when you have further information.

Hello John,

thank you for your support! I found the solution and what causes the issue. After FSUIPC starts from the EXE.xml the websocketserver connects not complete to the sim. So i stopped manually and restart it after the FBW was loaded  and everything works well as it should.

Thanks again for your assistance

Ah, ok - that is interesting.
Maybe the websocket server is expecting an FS version in offset 0x3308 when started, and that is now not populated until a simconnect connection is established.
You could check if this is an issue by adding
    Init3308=13
to the [General] section of your FSUIPC7.ini file, which will initialise that offset on start-up.

I could also delay the auto-start of the WebSocket server until a connection to MSFS is established, or until an aircraft is loaded?
Maybe @Paul Henty could advise on this?

Yes, that's what's happening. The WebSocketServer uses my DLL and that gets the version information when the connection to FSUIPC is opened.

Will 0x3308 be 0 before the SimConnection is made? I could check this in the socket server and retry until I get a proper version number.

Works!!! After adding

WebSocketServerAutoStart=Yes
Init3308=13

below the Autostart option it connects correctly. 

Great work, thank you so much!!!!

Yes

You could do that, but probably better if I delay the auto-start of the WebSocketServer until FSUIPC is connected to MSFS.
Your update would also help if/when the WebSocketServer is manually started before MSFS is running, but I could also disable the manual start until MSFS is available.

Great - thanks for the confirmation.

Note that you should set a value of 14 if/when using MSFS2024!
