Hello @tolesam I have a question. Does this PR intend to be used with the Ellipse Series, Ellipse 2 Micro Series, or both?

I'm interested in SBG products.

Hello @saengphet,
It's intended to be used with all SBG Systems' INS products.
Feel free to give us any feedback about it, we'll be happy to help you with our products' integration with this driver.

Hi @dagar ,

Can you take a look at this PR please?
I see you've already integrated another INS driver and we would be happy to have sbgecom driver available on PX4 firmware as well.

Moreover, it seems the job "Build and Push Container" doesn't work on PRs, do you have any idea why?
I tried to run it locally on ubuntu-latest and it worked well.

Thanks in advance.

I guess you didn't intended to commit this patch file

[tolesam]

It's on purpose.
I use FetchContent CMake method to get sbgECom public library only when the driver is enabled instead of getting it anyway with gitmodules.
And I apply this patch file to adapt sbgECom library to PX4 environment.
