Hello Georg,
Sorry for the delay. Is the issue solved?
For this issue, maybe the battery cannot provide enough power for the main board. Could you try to use new batteries and try again?
As you mentioned you have read FAQs, have you tried to enable location and gps option?

By the way, which app you used?
It fails to detect Bluetooth signal or detects it but not able to connect?
