if I add up all the time wasted in the past 2 years fixing problems with some blue tooth device it exceeds by far time spent on troubleshooting all other device connection options together (USB, LAN, WIFI, ...)
so I hope blue tooth will soon be superseded by something more stable and reliable - in the meantime blue tooth will get nowhere near my studio and live setup.
PS: even fairly recently released devices like superb sounding Eventide's H9 FX processor are much easier, faster and more stable controlled via USB connection than BT.
