Running NanoVNA-QT, or other remote application, causes the S-A-A-2 to enter "USB MODE" with a white screen. After closing NanoVNA-QT or other remote application, the S-A-A-2 remains in "USB MODE" and cannot be manually used without cycling power. This is very in-elegant and some type of reset or exit mode command should be provided.
