@Karteek-Gandiboyina Also, for reference: https://forum.modalai.com/topic/4403/starling-2-max-with-ublox-f9p-ultralight/7?_=1772217162290

@Karteek-Gandiboyina Unfortunately, we don't have any experience with that unit. It looks like it is hooked up correctly since you get a response from it. What baud rate did you change it to? You can try running the latest version of px4 but we have spent very little time testing it so use with extreme caution: http://voxl-packages.modalai.com/dists/qrb5165/dev/binary-arm64/voxl-mainline-px4_1.17.0-1.0.2-202602240859_arm64.deb. Perhaps load that, remove the propellers, and just verify that it can properly see the GPS? And what if you just remove the baud rate option on the start command, does that change anything?

@Sarika-Sharma We have a variety of parameters sets available in the voxl-px4-params repo https://gitlab.com/voxl-public/voxl-sdk/utilities/voxl-px4-params/ However, they are mostly for either indoor or outdoor use. Older versions of PX4, like what our fork is based off of, had a hard time with external vision based navigation coexisting with GPS based navigation. Newer versions of PX4, supposedly, are much better at this but we have not spent the time to prepare a parameter set for that yet. You are free to experiment with our mainline PX4 build here: http://voxl-packages.modalai.com/dists/qrb5165/dev/binary-arm64/voxl-mainline-px4_1.17.0-1.0.2-202602240859_arm64.deb. However, if you decide to use the mainline build, be aware that it is considered "experimental" at this point and has very little testing on voxl2 so use extreme caution.

@joshuagaus Sorry, but SBUS is not supported. That option will be hidden in future SDK releases to prevent confusion.

@Myles-Levine You should see an actuators tab. Do you have our standard VOXL SDK loaded on the drone?

@jameskuesel Thanks! Merged

@jameskuesel Feel free to make the change and submit a PR

@Eric-Katzfey And this is also handy: https://www.sparkfun.com/breadboard-to-jst-ghr-04v-cable-4-pin-x-1-25mm-pitch.html

@Gad-Levin We generally use HITL. There is some documentation here: https://docs.modalai.com/voxl2-PX4-hitl/. This is the repo with the most up to date HITL driver for VOXL: https://github.com/modalai/px4-firmware/tree/voxl-fpv-dev. There is some more info in the HITL driver README: https://github.com/modalai/px4-firmware/blob/voxl-fpv-dev/boards/modalai/voxl2-slpi/src/drivers/dsp_hitl/README.md. I'm sure there's some outdated / incomplete information in those documents but it should give you a pretty good starting spot. This is the cable I use: https://www.sparkfun.com/usb-to-ttl-serial-cable.html

@Myles-Levine Have you tried with the QGroundControl motor (actuator) spin tab?

@jon For MONOTONIC the apps side uses the slpi version so that they are in sync. Your application should use apps MONOTONIC. PX4 will convert it using timesync.

@Nitin-Varma-Vegesna Well, that's why I asked you to do the full SDK installation. If you install the SDK and set it up as we do from the factory then it should be working like when you first got it. If it doesn't then that potentially points to some damage caused by the crash and not some configuration change you have made since then.

@Nitin-Varma-Vegesna You can set parameters via voxl-configure-px4-params.

@kgn-mdlai Unfortunately, the April Tag code is quite outdated and hasn't been tested on any of our latest hardware. As it is now it is provided as reference code and if you are able to get things working correctly on your own we are happy to accept PRs to the repo. We do plan an update of this in a future revision of the SDK but there is no scheduled date that we can provide right now.

@tejasram The source code is here: https://gitlab.com/voxl-public/voxl-sdk/services/voxl-tag-detector. Perhaps try changing #define MAX_TAG_LOCATIONS 64 in locations.h.

@cbay That driver is not part of the build nor has it ever been tested on VOXL 2. You would have to add it to the build (e.g. in https://github.com/modalai/px4-firmware/blob/voxl-dev/boards/modalai/voxl2-slpi/default.px4board)

@taiwohazeez This is what most people use: https://qgroundcontrol.com/

@ggangmi What was the flight mode on takeoff and what did it unexpectedly change to? There should be logs in /data/px4/log. They may be incomplete or maybe even corrupted if the drone lost power in the crash but there should be something there. The logging starts when the drone is armed.

@Nitin-Varma-Vegesna If you re-install or update your SDK to the latest it will properly set all of the parameters.

@brandon You'll need to load SDK v1.6.x to get it.
