I'm trying to establish a bluetooth connexion between a Samsung Galaxy S3 running with Android 4.0.3 and a RN 42 Bluetooth Chip, here is the model : I used lot's of different codes for setting up a bluetooth serial communication, and all of them are working very well on the HTC Wildfire i was using before. But now that i'm using the galaxy s3 phone, it's impossible to establish the connexion. Here is the code i'm using, i found it here : I put the permissions in the android manifest. First, my Bluetooth Interface : public class BtInterface { private BluetoothDevice device = null; private

I am planning a communication protocol to be used between an Android device and a custom sensor that would use a commercial Bluetooth module. I would use the SPP profile that is said to "provide a simple reliable data stream to the user, similar to TCP." I am not so familiar with the Bluetooth technology and have some questions about designing such a protocol. First of all it is not clear to me if I have to worry corrupted data being transferred or not. Will the underlying protocoll stack guarantee me that the bytes I read from the InputStream Android gives are the same that the UART receives
