Primary accelerometer not found - QGroundControl

So I was trying to calibrate my Aero RTF on QGC when I came accross this warning message: "Warning: Primary accelerometer not found".which won't let me go through the calibration process (accelerometer calibration fails). Is there any way to correct this?

Thanks in advance!

So... Apparently, this error only occurs when PX4 is flashed. Just flashed ardupilot and configuring the drone was a breeze...All sensors were detected normally except for GPS but I suspect this is because I'm configuring it indoors.

Hope this gets fixed, as I'd rather use PX4 over Ardupilot.

Hello Daniel,

 

 

Thank you for your patience.

 

Which software version, bios and fpga version are you using?

 

I would suggest doing a frame reset from Qgroundcontrol once you flash the latest software as mentioned in the wiki setup instructions.

 

https://github.com/intel-aero/meta-intel-aero/wiki/02-Initial-Setup# calibration-1 https://github.com/intel-aero/meta-intel-aero/wiki/02-Initial-Setup# calibration-1

 

 

Hope this helps.

Configurations are:

BIOS_VERSION = Aero-01.00.13

OS_VERSION = Poky Aero (Intel Aero linux distro) v1.6.1 (pyro)

AIRMAP_VERSION = 1.8

FPGA_VERSION = 0xc2

Aero FC Firmware Version = 3.5.3

About calibration, that's the whole point of this question actually.

I can't get past sensors calibrations 'cause QGC won't detect the accelerometer if I load the Aero with the PX4 as per wiki (in other words, run:

cd /etc/aerofc/px4/

aerofc-update.sh nuttx-aerofc-v1-default.px4

)

BUT! If I load the Ardupilot instead, strangely enough, it WILL detect the accelerometer and all setup procedures will run smoothly, allowing me to fly the drone normally.

Thanks again!

Hello Daniel,

 

 

Have you performed a frame reset as I suggested earlier?

 

 

You can find the steps in the wiki guide here: https://github.com/intel-aero/meta-intel-aero/wiki/02-Initial-Setup# calibration https://github.com/intel-aero/meta-intel-aero/wiki/02-Initial-Setup# calibration

 

Navigate to the Airframe menu and select "Reset" to reset the drone's airframe configuration. Select "Apply and Restart" and restart the drone.

I have indeed! As a matter of fact just switched back to PX4 to double check, but still no accelerometer response specifically when on PX4 firmware

Hello Daniel,

 

 

Could you please tell us what is the version of QgroundControl that you have installed? Also, please send us a screenshot where you get the error message.

Hi Octavian,

Here are some SS, QGC version is v3.2.5 (I can't get it to show the "Not found" message, though)

Thanks!

Daniel

edit:

Now it will tell me there is no MAG SENSOR 0

Hello Daniel,

 

 

Thank you for the screenshots.

 

I would suggest you try and calibrate the drone from another computer with Qgroundcontrol and see if the same issue appears.

 

If the same thing keeps happening you can also try to calibrate the accelerometer using a nuttx shell.

 

You can find in the following thread somebody who had the same issue and found a workaround with a nuttx shell: /thread/118277 https://communities.intel.com/thread/118277

Changing computers did not work... Tried to do it from 3 different computers with no success...

HOWEVER working from Terminal DID work!!!

Used QGC's Terminal with command:

commander calibrate accel

which resulted in this callibration process:

Thanks again!!!!
