>> My objective is to read data from a bluetooth device alternatively.
1) I would like to connect to device 1. 2) Read data from the device 3) Disconnect from device 1 and connect to device 2. 4) Repeat from step 1 for device 2. I achieved this when I was using Processing language for Android. I took a video of the same: http://www.youtube.com/watch?v=MVut3Vn5BFAch I am also able to read and write data to the UART data module once the connection is established. I am not able to close the Bluetooth Socket and switch devices properly when I try to establish the above mentioned sequence. It seems to get stuck in an infinite loop.
