      Hi ModalAI, ^^

      I'm encountering issues with a certain compass on your flight controller.
      I detailed the issue here link text
      but in general I wonder, do you guys have any specific experience with this mag unit?

      I'll try and keep you updated. Thanks for your work, guys!

      Ch.B.

        Hi @m4v3r ,

        I'm nearly positive I tested CONNECTIVITY on the "drotek" version of this with success (I mainly remember that I did fry one out of two by reversing GND and VDD...).

        I'll try to find this when back in the office and give it a go and report back.

          @modaltb Hello there, I just wanted to give a little update here:
          I managed to connect it in a way that it's now appearing on the I2C bus as 23 by putting a 10k resistor on vcc and the I2C-enable pin but it's still not being detected by PX4 as a magnetometer and I couldn't start it manually either.
          I do see it on the bus just like with another mag ("gy-85" board using the QMC5883L and two other IMUs which also appear on the bus when scanned) but can't get it to start and work in PX4.

          Ch.B.

            Hey, just giving some more information and a little bump since I'm still in desperate need of this compass working on my drone.
            Please try and have another look into this for me if you could... 😉
            thanks so much and a perfect weekend for everyone.
            cheers

            Tried starting it manually to no avail:

              @m4v3r , sorry for the lag. This mag is not in our office. What I would do myself is go into the driver and see what's happening. We don't re-sell this mag and I don't have one so I'm stuck a bit. Do you want to ship one to us and we put a debugger on PX4 and see what's up?

                @modaltb Hey hey know it's been forever but just right now I finally got it working. 🙂
                I adjusted the adress in the corresponding driver's .h file and now it's finally running.
                thanks again for going through this with me.
                cheers
