Hi @TKuzmenko-EPS have you tested these to work with PX4?

fyi @hamishwillee

1. Do all of these really support CAN? If so they should be added to the list in https://docs.px4.io/main/en/dronecan/
2. If not, these should move to en/gps_compass/, and be renamed to match the convention there (rtk_gps_ardusimple_simplertk2b-budget.md.

Most important, there are no instructions on how to set this up with PX4. I can see your links, but they are to ArduPilot setup:

Please see https://docs.px4.io/main/en/dronecan/ark_rtk_gps#setting-up-moving-baseline-gps-heading for the kind of instructions we're looking for on usage if they do support CAN.

Please find our answers between the lines below:

1. Do all of these really support CAN? If so they should be added to the list in https://docs.px4.io/main/en/dronecan/
   **Yes, all these boards support DroneCAN via plugin CANBus GNSS Master https://www.ardusimple.com/product/canbus-gnss-master/ We have the standard dronecan connector (in addition to DB9) in the plugin since the last version, will be updated online shortly.
   Would it make sense to list these boards as "Supported via CANBus GNSS Master plugin" wiht link included to clarify that DroneCAN suppor at the table?

2. If not, these should move to en/gps_compass/, and be renamed to match the convention there (rtk_gps_ardusimple_simplertk2b-budget.md.
   Based on my reply above, I assume no need of changes. Please confirm.

Yes, all boards are Pixhawk4 compatible. you can find Pixhawk in the list on required hardware to follow the tutorial. this tutorial in particular is prepared with Holybro Pixhawk 6C , but it also works well with Pixhawk 4.

Please see https://docs.px4.io/main/en/dronecan/ark_rtk_gps#setting-up-moving-baseline-gps-heading for the kind of instructions we're looking for on usage if they do support CAN.
Thanks for sharing this example.
Documentation for our CAN support is currently under development, and we'll be happy to share it as soon as it's ready.
That said, I noticed there are already several boards listed in the PX4 documentation that link directly to external product pages without dedicated CAN setup documentation. Our proposal would therefore be at least as complete as some of the existing entries. Would it be possible to add our boards to the list now and improve the documentation over time as we publish our CAN setup guides?

Looking forward to receive your reply,

[TKuzmenko-EPS]

ve you tested these to work with PX4?

Yes, all boards are Pixhawk4 compatible

[mrpollo]

Did you test using a Pixhawk running the PX4 Autopilot firmware?

[TKuzmenko-EPS]

Did you test using a Pixhawk running the PX4 Autopilot firmware?
Yes, we tested it a while ago.

If repeating the tests with the latest PX4 Autopilot firmware would help get this pull request approved, we'd be happy to do so. in this case could you let us know what validation deliverability you'd like to see?

[mrpollo]

I don't know what tests you would be repeating and how you tested, but if its anything other than PX4-Autopilot your tests are meaningless.

What this codebase requires for testing is listed on our docs here, if you need help with the validate part, you can just upload a log to logs.px4.io and share a link here.
