Hello, I'm Chris from Berlin and I just wanted to kind of just introduce myself and say hi and wave over and all. Because I'm likely to ask questions here in the near future but I'm not at the point yet where I have all the information I need to ask the right specific questions you know?
I'm mostly whirling about MAVLINK errors atm but am personally more on the PX4 flying-side, like I know my way around flight controllers and drones and stuff. =P

@modaltb said in GPS/Mag - Connection woes and Firmware versions:

OK OK, I see what you are talking about.

Yes J1009 is a UART... but not configured for TELEM, this is where we map MAVLINK instances to UARTs:

https://github.com/PX4/PX4-Autopilot/blob/master/boards/modalai/fc-v1/default.cmake#L12

There is/was a max MAVLINK instance count (at least in 1.10/1.11) that prevented enabling another instance.

Are you setup to compile PX4? It might be you just need to add another instance after the line called out above.

For the UART instances, this is what we have by default, and you could mess around by changing these to fit your need.

		GPS1:/dev/ttyS0 # UART1  / J1012
		TEL1:/dev/ttyS6 # UART7  / J1010
		TEL2:/dev/ttyS4 # UART5  / (internally routed)
		TEL3:/dev/ttyS1 # USART2 / J1002

The form factor is off of a "racer" style, where we don't have all the interfaces like PX4IO etc, so you might find some limitations if comparing to other flight controllers with more IO.

Hey man, just wanted to let you know that against all odds this actually worked.
I put in the line describing TELEM4 and built the firmware myself and - tadaa!
Thanks again.

Hey everyone,
just wanted to let you know that my fix got merged into master so it should work for everyone now...

I'd have loved to change the title of this to something a little more descriptive but it's too late now I guess.
anyway, cheers everyone, happy flying.

@tom yes, will try and do so tomorrow.

actually it might not be feasible for me to snap actual photos I just made an image showing the basic concept
