Hi!
I have the Here 4 and I want to use it as a flight controller
I used the breakout board and FTDI but the MP does not recognize it
I thought maybe it needs an update with a cube but I don’t have the internet on my pc, there is a manual firmware that I can use?
Or any solution for my problem?

Get internet on your PC, all other solutions are too error prone and/or complicated.

I know, but still want to find a different solution
