Integra binding problem

[dimokl]

Hello guys, hope someone can help me cause it's my first drone and I have no idea where to dig. Just bought Flywoo Explorer o3 unit+fpv controller 2+ Integra and cannot bind it together. Installed DJI Assistant, have activated and updated all components to the latest versions. Bind between o3 and controller seems to be ok - I've got the led green and after that can hear beeps from the drone when I push C1, C2, changing the mode to manual, but not motor rotating.. But the worst thing is Integra - when it powered on, after a minute I got an error message "connection failed" ( yes, I configure it to o3 unit) and when I trying to start binding by pressing power - nothing happens - no beeps, just blinks like after one quick push to check the battery level....

Please HELP !

I read somewhere to bind the goggles first then the controller. You may want to try that.
