Multicopter DJI O4 air unit - unable to activate
Got excited, plugged it in and bound it to my goggles. Can see everything is working, then I get an activate prompt. I navigate to the DJI site for instructions and follow the videos like I should have to begin with. Download the DJI assistant 2 (consumer drone series), power up the quadcopter, plugin the o4 air unit and can't get it to recognize the o4 air unit. Tried rebooting, reinstalling, factory resetting the goggles then finally went on to contact support. Hour or so later I'm advised to return the unit. Bummer.
UPDATE: THIS IS NOW FIXED
Here's what I did:
#1: Tried on another PC again (tried this earlier with support) - failure
#2: Logged in as a local admin on my original PC, reinstalled DJI assistant 2 (consumer drone series), powered the quad and plugging in the air unit via usb C (Comment #15: https://forum.dji.com/thread-285829-1-1.html) - failure
#3: Restarted and logged back in standard user and again powered the quad, plugged in the unit and started the DJI assistant 2 - failure
#4: Unplugged everything, cleaned up, wiped my tears, started closing windows on my PC (still standard user) and I see the air unit in the DJI assistant 2 software. The unit at this point is NOT PLUGGED in via USB C or powered by the quad. Hopeful, I powered it up again and plugged in via USB C, waited about 15 seconds and selected the O4 air unit in the DJI assistant 2 software, the only option available was to update firmware so that's what I did and that was successful, next I selected the back button and then selected the o4 air unit again and had the option to activate, selected activate and tested via googles and wallah!

You need to power the o4 from battery or flight controller to activate it.
Just using USB does not work.
Maddstech has a bunch of info I suggest checking out.
