APm 2.5 + Ublox LEA-6 3DR = bad compass ?

I am getting totally confused, working for hours on bad compass results

- I just purchased the 2.5 (no 2.6 in Europe)

- I just purchased the Module GPS uBlox LEA-6 3DR which I think has the compass integrated

- I have cut the trace as suggested on the board (now I realise this is not good for the 2.5...)

- I calibrated the compass like in youtube

- I have used latest firmware...

In mission planner,

If choose external compass, it gives me an error msg : Set COMPASS_ORIENT Failed !

If I select the onboard compass, and enter my own declination (South of France), I can see the compass showing new results in the flight data window, BUT  when as I turn the quad around,

- very slow to stabilise the results. I can stop moving the quad, then numbers are slowly going up or down but eventually showing wrong direction numbers

- turning around and stopping at the same point, it never shows the same results, sometimes wrong by as much as 90 degrees.

- obviously then, I obtain fly-aways for RTL...

So... Was I totally wrong to cut the trace on the 2.5 ? Would it work only on 2.6 ?

Anything else I could do ? I am having a true headache here...

Magfied reads 290. Is this too much ?

  • +++ I had used the "calibration dance" as per youtube example, with "standing-up-guy-and-dancing" the method.

    I had resutls as mentioned above.

    I have just now used the "quiet-guy-sitting-in-a-chair" way, and results are way better.and look correct.

    Now...

    When I select the "external compass" choice, then go to Flight data, then come back to check my compass choice, check has disappeared, and only shows "compass : enable". So I am still lost... Am I using the internal or external compass... How can I know please ?
