      @Eric-Katzfey Yes, manual and altitude modes work well,

      1. I started with GPS+Mag+baro but drones couldn't find the mag, sometimes finding the mag but suddenly losing it.
      2. I used VIO but sometimes lost the figures and lost the position.
      3. Yes, I loaded the specific parameters file for outdoor, and indoor, I tested all of them and checked all the scenarios, but drones outdoors can't fly in position mode without VIO, and with VIO is not stable.

      When I turned on the Mag, I had an error: No valid data from Compass 0

        @Amin-Bassiri I think the first thing is to figure out what has gone wrong with the mag. You need to get it flying nicely in position mode with GPS / Mag / baro first. VIO is trickier, especially outdoors. Since it relies on computer vision for it's tracking it can fail for quite a few different reasons and is more difficult to debug. VIO indoors where the environment can be controlled more closely is ideal. Outdoors VIO can be a lot more challenging and there will certainly be cases where VIO will fail. Outdoors it's probably best to use both GPS and VIO simultaneously and have PX4 fuse these measurements internally depending on the quality of each one at any particular time. Regardless, let's figure out what is going wrong with the mag first. Does the mag problem happen on all 7 drones? Are you able to calibrate the mag on any of them?

          @Eric-Katzfey Yesterday I tested seven drones with outdoor parameters. One of them could fly in position mode, and another could fly in position mode but was drifting. The remaining five drones couldn't enter position mode.

          The same drones, the same parameters, and the same environment, but different behaviour.

            @Amin-Bassiri So, does the mag problem happen on all 7 drones?

                @Eric-Katzfey We tested all seven drones and only two of them are working. However, when we swapped the GPS devices, the working drones also failed to work. This suggests that the issue might be with the GPS devices themselves.
                Specifically, two GPS devices work with different drones, but the remaining five GPS devices do not work with any of the drones.
                Also when we set the SYS_HAS_MAG to 1, the drones can not fly, so we set it to 0 (all the drones)
                it seems we have the hardware problem
                What we should do now?

                  @Amin-Bassiri On one of the non-working drones can you capture the output of journalctl -b --no-pager -u voxl-px4? I'd like to see the output that px4 is generating as it starts up.

                      @Amin-Bassiri Looks like lots of GPS accuracy checks failing. Can you set EKF2_GPS_CHECK to 1 and see how that works?

                        @Eric-Katzfey I changed, but it seems the problem is the GPS device, because when we change the GPS drone can go to position mode, but we still have a problem with MAG, we have to turn off the MAG, The drone can not go to position mode, and also we have too much drift.

                        when we set EKF2_GPS_CHECK to 1:

                          @Amin-Bassiri For some reason the journalctl output doesn't have all of the output from voxl-px4 startup. It should show the attempts to find the magnetometer that seem to be failing. The command in the startup script is qshell ist8310 start -R 10 -X -b 1. If you run that command from the px4 console you can see the output. Or from Linux shell px4-qshell ist8310 start -R 10 -X -b 1.

                              @Amin-Bassiri Shoot. With px4-qshell ist8310 start we don't see all of the output. That command needs to be run in the px4 shell to see the output (i.e. qshell ist8310 start -R 10 -X -b 1). When I have no magnetometer attached to my VOXL 2 and I run the command I can see that the probe fails. For example:

                                @Amin-Bassiri Regardless, based on your earlier log file it seems like the magnetometer is being detected and is providing data. But you are still seeing the No valid data from Compass error. The log you provided does show the error_count incrementing which indicates failed i2c transfers from the magnetometer. So I am also suspecting hardware failure of some sort. Let me discuss internally to figure out next steps.

                                  @Eric-Katzfey We can test a couple of GPS / Mag units with RB5 and send known working units to you and see if you can also replicate that success. If so, we can send you 5 more.

                                    @Eric-Katzfey Can you send a picture with both the GPS unit and cable? Just want to double check what unit(s) you have. I am currently testing with the mRo GPS / Mag unit on my RB5 running SDK 1.1.2 and it is working fine. I have 2 of them that seem to be fine so we can send those to you to try out on your drone(s).

                                        @Amin-Bassiri Really sorry that you guys are having so much trouble with the GPS units! We are now shipping with M10 GPS units so we can send you those and hopefully that will improve the situation.
