Doing with gesture recognition sensor sent via bluetooth gestures instruction, but the program always stuck in the while (! TI) loop, the death of his note gestures can recognize but bluetooth hair don't go out; Keep the gesture recognition directly if no response,,, the procedure is as follows, BBS typesetting
