After all the euphoria for the handoff feature, I am unfortunately very disappointed. Because many people have reported that the stick has a suitable Broadcom chipset and support handoff would, of course I immediately slammed shut. But just trying out & Configure I noticed that he now held a new chipset from "Cambridge Silicon Radio". Low energy and high reach but not be supported handoff.
Thus it has done for me. Complaining does not worth because the stick was sent directly from Hong Kong. Maybe he does not get anywhere else what profitable (Raspberry Pi). Well too bad, 15 down the drain.
