For two weeks I’ve been working on this so I thought I would post here, maybe it will help someone.
I have a Speedybee F405-Wing V2 SpeedyBeeF405WING/ Wing Mini — Plane documentation flight control and I’m trying to connect a DJI Air unit 03 to get OSD telemetry.
Serial 5 on the FC has a plug for “DisplayPort OSD”, so I follow the instructions and set;
OSD_TYPE = 5 (MSP_DISPLAYPORT)
SERIAL5_PROTOCOL = 42 (DisplayPort)
SERIAL5_BAUD = 115
SERIAL5_OPTIONS = 0
MSP_OPTIONS = 4 (BFFONTS)
However with this setting the OSD in the goggles will just NOT work?!
So, I switched the wires over to Serial 6 after checking the wires the Air unit etc etc; this is normally used for the WIFI ‘Dongle’ (which works well btw with MavLink 2). I set
OSD_TYPE = 5 (MSP_DISPLAYPORT)
SERIAL6_PROTOCOL = 42 (DisplayPort)
SERIAL6_BAUD = 115
SERIAL6_OPTIONS = 0
MSP_OPTIONS = 4 (BFFONTS)
After switching ports everything works correctly with HD OSD. So don’t believe everything you read
