my pixhawk can not connect to the QGC(v2.2.0) or MP with px4 firmware.And the main LED is always breathing blue, I'm not sure what does that mean.

QGC can find  the board and the bootload except the firmware .I reload the firmware as QGC's suggestion.but it doesn't work.The QGC suggest me to reload the Firmwar again.

Then i try the apm's firmware(v3.3) ,then my pixhawk can connect to both QGC and MP .

But i need the px4 firmwar, Does anyone know how to solve this problem or has the same problem?

the prints while connecting to the QGC with px4 firmware are as follows:

Link COM4 is unconnected. 

Opened port!
Link COM4 is connected.

  • Hi I had a problem with my px4 started to do firmware update then stopped after px4 rebooted so looked in device manager on pc
    Px4 shied up but no drivers so reinstalled drivers at that point and tried again and it worked
    Hope this helps

    • Thankyou for your post.

      I have fixed that problem.After I flashed my firmware , there is no response when I turning the pixhawk unless I choosed the frame type of the aerial vehicle.

  • anybody knows that ?
