In the factory state, you can see the reer WLAN. As soon as a connection is attempted, it disappears.
There are two ways to reactivate it:
- when the camera is on, press the reset button once, then the camera switches to settings mode and reer Wifi is back -> this is used, for example, to be able to connect several WLANs
- Complete reset of the camera (I think it was 10 seconds with the reset button at the top) -> Attention: all settings will be completely deleted

We were initially only able to configure the camera with the iPhone app. Afterwards, however, it also ran via the Android app. But that was about 3 years ago.
