I have O4 Air Unit(lite), Remote 3 and Goggles 3 connected together. It works fine and displays the video feed including OSD overlay from betaflight. Signal strength for video and RC is max. All good but… SBUS signal (yellow wire) from the Air Unit is not working and Betaflight Configurator shows no movement on the receiver tab when I move the sticks. I even tried measuring on the SBUS signal with an oscilloscope and it goes high after power up and stays high for 3.5 sec, and then stays low afterwards. So no SBUS communication.
I even bought a second 04 Air unit to test if I had a problem with the first, but the second acts the same.
Note. All firmware is updated to latest. On Googles 3 under Settings->Control I tried both Normal and SBUS baud fast
Any help would be highly appreciated. I have been strugling for a week now.
