MP 1.3.16, Windows 7 64 bit, USB link to APM 2.6 with separate compass/GPS (generic brand).
I can no longer connect to my APM using the terminal function. This used to work with older versions of MP. I get a lot of gibberish on the screen (see attached file). I also can no longer download logs, the screen also fills up with gibberish and beeps.
Everything else seems to work as before: mavlink connect, flight plan, flight data, firmware update, compass calibration… I am able to see the status of the APM in the flight data window (GPS status, orientation, compass…).
What could be the problem? I checked similar threads and the issue seemed to vary: bad APM, wrong speed setting on COM port, etc. I checked all these as best I could and everything seems correct. Your help will be appreciated by this newcomer to quadcopters (old radio control modeler from the 70’s).
