Help with Voxl2 PID Tune problem

[Eric Katzfey]

@bensusana Can you provide some more information to help us rule out any obvious configuration issues? For example, a px4 log from journalctl -b -u voxl-px4 --no-pager on voxl2?

hi eric , i uploaded the log here (too many characters )

if you guys can support us through email it will be much faster .
thanks.

@Eric-Katzfey I don't see anything obviously wrong in either the flight log or the startup log. The log of the input_rc topic doesn't show any obvious dropouts or other problems but it is not logged at full rate so it's possible that it didn't capture something bad.

hi guys,
we about to build 4 more drones with same setup ( 8 total) and we have to be sure about the hardware, how can you help us to work this through?
can one of the dev team can give us support through emails? its hard to support this with one massage a day ( we have time zone problem )

@bensusana Hi Ben, Eric is our head of software so you are getting the best support we can offer at this point. Do you have developers you work with who can help debug PX4?

We are working on a new firmware for that VOXL 2 IO board that we hope to help resolve some of your issues. We are a few weeks away though from the release.

For the direct CSRF connection, are you using the latest SDK or is it still the older version?

@Moderator Sdk 0.9.5
Crossfire nano rx connected to j19 ,using mavlink mode.
For unknown reasons in this mode I can control the drone but a lot of mavlink massages disappear, no battery status system status almost half of the tabs in mavlink inspector on qgc are gone .

What I’m doing wrong?
Can I use csrf raw on that Sdk?or should I move to v1.0?

should I try use spectrum receiver?

[Eric Katzfey]

@bensusana Using the TBS Crossfire receiver in mavlink mode shouldn't have any affect on the mavlink messages you get at QGC. The TBS Crossfire driver runs on the DSP and communicates to the receiver using UART. It uses the Mavlink protocol over that UART. The Mavlink module is a completely separate thing that runs on the applications processor and communicates to QGC via the network. So it is unclear to me how one would influence the other in any way. You can certainly try it in CRSF mode. You can also switch to Spektrum. For full M0065 support of both RC and PWM we would recommend waiting for the upcoming 1.0.x release that supports that combination.

@Eric-Katzfey how to start the system with crsf raw mode?
i didnt found it on the modalAi portal .
for mavlink mode i tracked open topic that says use voxl-px4 -r for mavlink...
this link : https://docs.modalai.com/voxl2-rc-configs/#crsf leading to "page not found"

thanks for the support !

[Eric Katzfey]

@bensusana Use -c instead of -r. Baudrate will be 250000 for CRSF (It's 115200 for Mavlink mode).

hi guys ,
quick update , after a lot of testing and after we take out the IO board and still got some wobbling from the drone , we re-calibrate the f55 esc we got diffrent results from the last calibration , after updated the last resullts we did a flight test and the drone fly smoothly .

thanks for the support ,
i hope that this topic will help others

@Eric-Katzfey

only 420000 work for me for CRSF RAW
