Lumenier RID & M10Q GPS Module compatibility
-
@Alex-May It really looks like there is no communication going on between the GPS and the VOXL 2. Can you attach an oscilloscope to the rx and tx lines to look for activity? Usually the M10 units come up and start sending NMEA strings at 9600 so you would be able to detect that on the scope.
@Eric-Katzfey I don't believe we have a scope available for at least a few more days. But I do have other M10 GPS units I could try.

@Eric-Katzfey I am Alex's co-worker and helping with the building the magnetometer's driver into PX4.
I am following instructions outlined here: https://gitlab.com/voxl-public/rb5-flight/rb5-flight-px4-build-docker#install-qualcomm-package-manager
I am having hard time downloading the hexagon SDK from qualcomm. I see v3.1 is available on your website. Am I going to need 4.X or I can use 3.1

@psafi Yes, unfortunately it is a real pain to get the SDK from Qualcomm and you need that version.

@Alex-May The driver for that magnetometer has not been built into the image so it won't work without adding that driver. As for GPS it seems like it isn't communicating with the receiver. Can you run this experiment: Stop PX4 with
systemctl stop voxl-px4, wait a couple of seconds, then start px4 from the command line withvoxl-px4 -dand post the output from that? -
@psafi Yes, unfortunately it is a real pain to get the SDK from Qualcomm and you need that version.
@Eric-Katzfey I am able to build voxl-px4 now.
I am following instructions outlined here to add this magnetometer:
https://forum.modalai.com/post/16770I am adding following line:

@psafi Those should only be there on the Nuttx platform.

Sill not detecting lis3mdl module on the px4 side.
I tried adding the following to /usr/bin/voxl-px4-start
qshell lis3mdl start -R 10 -X -b 1but I think that causes px4 service fail to start. Not sure if that means the module has not been successfully added to voxl-px4 or some other issue.
Are there any steps I need to take besides adding sensor name to default.px4board file?

@psafi If you disable the px4 service (
systemctl stop voxl-px4) and then start it from the command line (voxl-px4 -d) what output do you get? And if you disconnect the magnetometer from the system how does that change things? Remove the start command from voxl-px4-start and enter it after px4 starts from the command prompt to see what happens. -

@psafi And how did you load your updated build to the VOXL 2?

@psafi I just built voxl-px4 with the lis3mdl driver and when I run it the command fails because it fails the probe (I don't have that magnetometer) but otherwise runs normally.

@Eric-Katzfey by installing debian package and I got output similar to this after installation:
https://gitlab.com/voxl-public/voxl-sdk/services/voxl-px4#deployment -

systemctl stop voxl-px4) and then start it from the command line (voxl-px4 -d) what output do you get? And if you disconnect the magnetometer from the system how does that change things?

I guess rebooting the board earlier did not have the same effect. The compass calibration in Q is working now (no more "no mag found" error) which I guess it means the mag is working now and our gps is working too.
here is the output of voxl-p4 -d by the way:
