I think I need your help....
I have a Blitz Mini F7 controller, a Crossfire Nano RX and the o3 air unit. This also works wonderfully. But without OSD.
Connected as shown on the diagram. The o3 is with pin3 (white) on the FC RX, and pin4 (gray) on the FC TX.
However, it says that RX & TX are to be swapped on the FC. Then I don't even have input in Betaflight 4.4 (not even in 4.3). The radio tells me anyway that the is connected.
Via the console I can't send a: set displayport_msp_serial = xy even with the swapped RX/TX variant. It does not know msp "serial". Of course I entered set osd_displayport_device = MSP before.
With Betaflight 4.4 I don't need this step anymore.
Does anyone of you have an idea what I can do?
Greetings from Germany
