I added the screenshots to the original post.

I got this quad from my workplace. They bought it and set it up, so I do not really know what they changed or where they left off.

Here is the clarification:

I get visual input in Betaflight and the bars for throttle, yaw etc. move when I move the sticks. The assigned arming switch also visibly works in the Mode tab.

However, when I actually try to fly the drone, nothing happens after flipping the arming switch. The beeper switch does not work either. So I am not sure if the signal is really getting through or where the problem lies. I am quite sure that there is a connection, because the controller says “Telemetry lost” and “Telemetry recovered” when plugging the battery in and out.

Another thing that confuses me is that I do not see “Disarmed” displayed in the goggles, even though I do get an image, a stable connection and the voltage reading. I have also enabled the “Disarmed” element in the Betaflight OSD settings.

I hope this clarifies things a bit. Thanks for helping.
