I tried to use encoder parameter in voxl-streamer to record h265 encoded videos from the tracking camera but looks like it was not implemented in this SDK version.

Is there any options to record h265 encoded videos from the tracking camera? Also, is the tracking camera video only grey or it is possible to configure it as coloured?

Thanks

After running "voxl-configure-px4-params --platform MRB-D0006" to configure RB5 PX4 parameters, I could perform an outdoors flight with RB5 using Position Flight Mode without GPS or motor problems: https://youtu.be/D8zP0hOx8wc

It seems that the issue was RB5 running with Sentinel PX4 parameters after SDK upgrade.

Thank you for your help

@Eric-Katzfey

Ok, thanks

Can I use the file:
https://gitlab.com/voxl-public/voxl-sdk/utilities/voxl-px4-params/-/blob/master/params/v1.14/ci_helpers/ci_sentinel.params

To configure RB5 px4 parameters using QGC?

I didn't find a specific file to RB5 in the folder

Hi @Alex-Kushleyev

I used the voxl esc spin tool a few times to each motor and all of them worked fine.

Here are one of the outputs: https://www.mediafire.com/file/bw31xds0j2ohlod/motors-spin-test.txt/file

I tried some flights using Position Flight Mode and had the same problem showed in the youtube video above. Here are the logs: https://www.mediafire.com/folder/jbuu2or25tjdr/position-flight-mode-logs

I don't know if the problem really is with the motors or if it could be related to the accelerometer or magnetometer due to the https://forum.modalai.com/topic/3612/outdoor-navigation-gps-problem/11?_=1720094809242 problem, for example, or it might be a misconfiguration of any of the PX4 parameters due to the SDK upgrade...

What are your suggestions?

Thanks!

Hi @Eric-Katzfey

As you said, QGC and PX4 were receiving GPS data from M8N, however, EKF2 couldn't estimate the global and local valid positions.

After changing EKF2_MAG_TYPE, which value was as None, to Automatic, EKF2 could finished the global and local valid positions estimation and the drone became Ready to Fly with no issues from QGC.

So, now, after changing EKF2_REQ_SACC to 0.8m/s and EKF2_MAG_TYPE to Automatic, the drone became Ready to Fly and I could arm it using GPS.

Which is curious though is that here https://gitlab.com/voxl-public/voxl-sdk/utilities/voxl-px4-params/-/blob/master/params/v1.14/EKF2_helpers/outdoor_gps_baro.params in the EKF2 helper file, which I used to first configure the drone's PX4 params after upgrading from VOXL SDK 0.9.5 to 1.1.2, it says to set EKF2_MAG_TYPE to 0, so I am not sure if setting EKF2_MAG_TYPE to Automatic is the right fix, what are your thoughts? Is 0 meaning Automatic?

After setting EKF2_MAG_TYPE to Automatic, I tried some flights in Position Flight Mode and had the same problems of when I had tried the Manual Flight Mode flights (The one showed in the youtube video above), which @Alex-Kushleyev is helping me to figure it out in the https://forum.modalai.com/topic/3634/rb5-can-t-leave-the-ground-properly-when-flying-in-manual-flight-mode/ topic. The logs can be seen here https://www.mediafire.com/folder/jbuu2or25tjdr/position-flight-mode-logs

Thanks!

No, I had never used the voxl-esc tool before.

The vehicle was running with VOXL SDK 0.9.5 (not sure if it had the voxl-esc tool) and PX4 1.12beta and we did have a few successful flights, so the motors were working properly.

After upgrading to VOXL SDK 1.1.2 and PX4 1.14 the issue started happening and we could not flight fine yet.

Thanks!

Hi @Eric-Katzfey

Yeah, I will try in another open field in a different location and experiment with the various GPS thresholds you mentioned. Thanks!

We did a site survey in the open field area we tried the flights and we got the results below:

We used an AARONIA AG HyperLOG Broadband Directional antenna and a Spectrum Analyzer.

It might help.

Hi,

When I tried a few outdoor flights with manual flight mode without GPS (EKF2_GPS_CHECK=1 && COM_ARM_WO_GPS=1), one of the drone's rotors seemed to not be working properly. You can see it in this video: https://www.youtube.com/watch?v=F7ug6u2W8Yw

It happened after upgrading from VOXL SDK 0.9.5 to 1.1.2 and during testing flights to the https://forum.modalai.com/topic/3612/outdoor-navigation-gps-problem/ problem.

Here are the logs of two of the outdoor flight attempts with manual flight mode: https://www.mediafire.com/folder/qhidipn0n1xng/RB5-outdoor-flight-logs

Is there any PX4 parameter I could change in order to try to fix it?

Thanks!

@Moderator Yes, how can I do that?

@Eric-Katzfey, yes I am trying outdoors. I am even waiting more than 10 minutes too see if the GPS locks but it doesnt

Thanks in advance!

I created a new topic about the GPS problem https://forum.modalai.com/topic/3612/outdoor-navigation-gps-problem

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?

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 files missing are:

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?

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?

@Moderator, thanks for your reply.

The px4 version is v1.12.31 (beta)

Do I need to upgrade it too?

Does the SDK upgrade process update px4 automatically?

Yes, @tom.

Thank you

Re: Calibrate IMU RB5

Hi,

We have a RB5 drone and its voxl-version is:

We didn't upgrade the build yet.

In relation to the problem, we did some flights and experienced it again.

Below are the flight logs, you can use: https://logs.px4.io/upload to visualize them.:

https://www.mediafire.com/folder/74yd2f8tdnjqq/RB5_flight_logs

In the flight with problem, we performed sensors calibrations using QGC.

The flight with no problem happened a couple of hours after the first flight with problem and no calibration was performed.

Can you find any indicators of the problem in the logs, such as high temperature, for example?
