Hi all,

I have problem connecting the APM 2.5 to Mission Planner via USB.There is no problem in uploading firmware but when I try to connect to the board for example in "Flight data","Configuration",... it fails.

All of the tests in CLI are OK.

Several people have the same problem:

I tried the mentioned solutions in those threads but none of them couldn't solve the problem.please help me to resolve it.

Board: APM2.5

OS: Windows 7,32 bit

Mission planner: 1.2.43 mav1

Thanks

Stephan

  • I uploaded a video on YouTube that show my problem:

  • Finally I changed the firmware from hexa to quad, so I could connect to the board in "flight data" but now another problem:

    It's very slow in motion,I mean when I turn my frame to the left or right ,mission planner shows it 2 seconds later.

    Please help me on it?

  • I had the exact issue. Turned out to be a power problem.

    I my case, my USB port couldn't power the APM and my rx at the same time. I had to connect the APM by itself, no rx, no telemetry radio if the USB port was the supply.
