Never had much problems with BT while indoors. Outdoors, particularly walking down streets, may be a different matter. Tricky bit about BT is that it is actually designed to bounce of surfaces to some degree. This because in its most basic form, that of a wireless earbud connection, it may not be able to penetrate the human body. So to work around issues with devices being on different sides of a walking, talking, bag of water, it tried to make use of echos from nearby walls and other suitable surfaces. End result is that in a environment that is constantly shifting, like out on an open street, performance will be hit or miss from moment to moment. But when indoors and stationary i have been able to get a phone to talk to a tablet and earbuds, while the tablet also talks to a keyboard. And this was all kit from before BTLE...
