• I just tried - it wasn't the link security though. :(

    What irritates me is that it's listed on my desktop PC, my laptop, my Android phone, ... only the Dell thin client doesn't see it. Though when I clone it in the NRF Connect App the cloned "device" gets listed also on the thin client. That's very strange!

    Anyway - thank you very much for your help!! No thanks to Dell though. ;)
