Drone does not switch to Position mode indoors
We have just received a pair of Seeker drones. One of them works flawlessly indoors (w/ Vision enabled, w/o GPS); however, the other does not switch to the Position mode under the same circumstances, regardless of our efforts. It can switch to Manual, Altitude, and Stabilized modes, though. I made sure that the parameters were the same by exporting/importing; and made the calibrations as well. What else should be considered?
@Umut-John Sorry to hear you're having troubles with one of your Seekers. Let's see what we can do to remedy that.
First off, some questions to get a baseline where we're sittin.
Was any custom software loaded?
Have you configured MPA?
When I see that the Seeker doesn't go into Position mode, VIO hasn't started or didn't start properly.
Can you post the result of:
What software are you utilizing?
If you look at local position ned in QGC(Q Ground Control) What does the X and Y data show? If they're zeroed out, then you will have to restart VIO. To get to local position ned, open QGC, navigate to analyze, mavlink inspector, local position ned.

Hello Adrian, thanks for the prompt response. There is no custom software/hardware. Configuring MPA didn't seem to help either. And here is the output of "voxl-inspect-services" command:

And here is the output for "voxl-version":

Finally, there is no Local Position NED tab in the MAVlink Analyzer Tool in QGC.
By the way, "voxl-qvio-inspect" command gives the following output:

@Umut-John can you try restarting the voxl-vision-px4 service and qvio server?
systemctl restart voxl-vision-px4
systemctl restart voxl-qvio-server
Tried both multiple times, no changes, unfortunately. I'd like to add that in the VOXL Portal, there are no camera streams for the tracking cam and Qvio overlay channels (which are all black), although stereo cams and tof streams seem to work.
@Umut-John that's interesting. Do any of the other cameras come up in Portal?
Can you post the print out of
Which camera config do you have on your Seeker? Does it have the TOF or Hi-Res?
You may want to try configuring the cameras.
It's interesting that the tracking camera is not showing up. The Seekers are test flown and tested before shipping out.
Stereo cameras and Tof streams work, but not the tracking. "camera-test" returns the following:
num_cameras = 4 Testing camera id=0 camera-test: /opt/workspace/build/apq8096-le-1-0-1_ap_standard_oem.git/apps_proc/poky/build/tmp-glibc/work/armv7a-vfp-neon-oemllib32-linux-gnueabi/lib32-qmmf-sdk/git-r0/qmmf-sdk/recorder/src/client/qmmf_recorder.cc:326: qmmf::recorder::status_t qmmf::recorder::Recorder::DeleteVideoTrack(uint32_t, uint32_t): Assertion `recorder_client_ != __null' failed. Aborted
And this is what I see in the portal:
@Umut-John hmm. One more thing to check; is there a lens cap on the tracking camera?
It does look like the camera is detected
OMG! The protective cap on the camera
You're right! Just saw it minutes before checking it here. There was no cap on the first drone; it was probably dropped or something, so I did not even feel the need to look for it.
Thank you, Adrian; sorry for the trouble. Case closed!
