2 months ago Hi, Seems the server is busy somehow the CANoe GUI got hanged, could you try closing the application and execute it once? Also make sure there is only one CANoe instance running.
Describe the bug I have a program to read data from an embedded system. I use this twice during my program, and the first time works fine every time. When it finishes that, it goes on to read some serial data and some other log data for a few seconds (I should mention that the CANoe simulation stays open in the background the entire time this is happening). When I return to CANoe to send more diagnostics requests at the end of my program, it gets stuck trying to send '10 03', and using the VSCode debugger I can see that it's stuck in the "while diag_req.pending" loop. I also get a warning from my OS saying "Server Busy" with options of "Switch to", "Retry", or "Quit". Upon clicking any of these buttons, either the CANoe GUI opens up and freezes, or it closes down and the Vector support app immediately opens, which usually breaks my program and closes it. Closing CANoe through the small icon on the windows taskbar also has the same effect.
To Reproduce Steps to reproduce the behavior:
Expected behavior I want the program to continue to send all diag requests without freezing.
Screenshots Cant paste for some reason so here are some logs:
The window I get says: "This action cannot be completed because the other program is busy. Choose 'Switch to' to activate the busy program and correct the problem"
Then with options of: "Switch to" "Retry" "Cancel"
