Possible workaround for Bluetooth pairing issue in ICS

It seems that the problems with Bluetooth serial profile (SPP) in some Android ICS phones may have a workaround as described here:

Basically only unsecured serial socets seems to work for some ICS releases. The workaround as suggested is to use
private BluetoothSocket createBluetoothSocket(BluetoothDevice device) throws IOException {
if(Build.VERSION.SDK_INT >= 10){
try {
final Method m = device.getClass().getMethod("createInsecureRfcommSocketToServiceRecord", new Class[] { UUID.class });
return (BluetoothSocket) m.invoke(device, SPP_UUID);
} catch (Exception e) {
Log.e(TAG, "Could not create Insecure RFComm Connection",e);
}
}
return device.createRfcommSocketToServiceRecord(SPP_UUID);
}

If the MyPhoneExplorer client could offer an option to use this instead of only the regular createRfcommSocketToServiceRecord maybe all the ICS phones can work with MyPhoneExplorer.

This problem does not affect MyPhoneExplorer cause he does host a Bluetooth-Service on the phone, the issues you see do open a connection from the phone to another device, MyPhoneExplorer does connect from PC to phone using the API listenUsingRfcommWithServiceRecord.

The problem also exists for connections from PC to the phone and does affect MyPhoneExplorer. The error seems to be introduced somewhere between Gingerbread and ICS. The listenUsingRfcommWithServiceRecord just seems broken in ICS on many phones.

It seems that only the unsecured version works, regardless of direction.

Which phone model do you have and which Android Version ?

I have a Sony Xperia Go (ST27i) with ICS (4.0.4). This prooblem seems to affect all Sony Xperia phones with ICS (the ones not yet upgraded from Gingerbread can use BT with MyPhoneExplorer). The problem seems to also affect the earlier Samsung phonmes with ICS, but not the newer ones.

Can you reproduce the issue (to check if a change would help) ?

Absolutely, no problem.
