initial
btlab : can compile, download to android phone, start app, see gui , but can not pair to another type of phone like windows phone. not sure another android phone will work or not. guangli said possible caused by bt version and phone os.
we will make a bluetooth based chat on this.
then we make btlab on btchat.
