Persistent "no robot controller found" error
We've had a sporadic error in the past few days. When we try to download any hex file to the robot with IFI Loader, we get the error "No robot contoller found," with the IFI_Loader error window that reminds us to check power is on, cable connected, and Program State LED orange.
We have doubly checked all of these things, and we've confirmed IFI_Loader is using port COM1 (our only COM port). We reinstalled IFI_Loader and restarted. We have charged the blue RC backup battery. We are running v.1.1.0 of IFI_Loader.
We tried using our computer with last year's RC, and we can verify the robot controller connection, which makes us think this may be an electronics problem?
We can't even download the default code, which makes us think this wouldn't be a programming error... We had this problem Saturday, and then things worked Monday, and then Tuesday the problem recurred.
