I have almost the same problem after late updates, but even worst. I CANT connect anymore, even after reboots. The app indicate CONNECTED but no audio nor frequency indication. Also DISCONNECT works OK but nothing more.
Setup here is the same as long ago SONY XPERIA T3 and latest, installed yesterday, updates of NANO-S 2.0.2 and NANO-K 1.2.2.
Any advice, pse??
