Unknown px4 firmware after SDK upgrade

[vjuliani]

Hi,

After I flashed VOXL SDK 1.1.2 on RB5, the firmware version is unknown in QGC.

This is voxl-version:

What should I do?

Also, I lost the calibration files of gyroscope, accelerometer, gps, etc. Can you send me them?

To flash VOXL SDK 1.12, I used an ubuntu 22.04 laptop and did run the install.sh script.

After that I had the error above in QGC.

Is there any more steps necessary to upgrade the SDK and PX4 firmware?

The files missing are:

@vjuliani Can you rerun those calibrations?

@vjuliani QGC may complain about our version of PX4 but that is okay. We have a forked version of PX4 and the parameter sets don't necessarily align perfectly with what QGC wants to see.

Hi, @Eric-Katzfey

Thanks for your reply!

I runned voxl-configure-mpa again and the problem was fixed.

Also, I did all the sensors calibration and it worked.

However, even after upgrading VOXL SDK from 0.9.5 to 1.1.2, I am still having the same issue when trying outdoor flight.

The issue is similar to the https://forum.modalai.com/topic/3410/outdoor-navigation-problem one.

When I try an outdoor flight in position mode using EKF2_GPS_CHECK to 245, QGC shows a lot of GPS Speed Accuracy too low failure messages. With that, the drone status remains in Not Ready and it can't fly.

If I try to set EKF2_GPS_CHECK to 1, I get Pre-flight check failure: GPS Position Required messages from QGC. So, the status remains in Not Ready and the drone can't fly.

The only manner I found the drone flight to work was to set COM_ARM_WO_GPS to 1 and use altitude or manual flight mode.

I think it might be a gps hardware issue, like the one in the topic linked above.

The GPS model I had is M8N and I already had this issue with VOXL SDK 0.9.5.

Any suggestions?
