In case it's helpful, here's the relevant code:
https://github.com/piusvelte/RemoteAuthClient/blob/master/src/com/piusvelte/remoteauthclient/RemoteAuthClientService.java
public ConnectThread(String address, String state) {
mAddress = address;
mState = state;
BluetoothDevice device =
mBtAdapter.getRemoteDevice(mAddress);
BluetoothSocket tmp = null;
try {
// tmp =
device.createInsecureRfcommSocketToServiceRecord(sRemoteAuthServerUUID);
tmp =
device.createRfcommSocketToServiceRecord(sRemoteAuthServerUUID);
} catch (IOException e) {
Log.e(TAG, e.getMessage());
}
mSocket = tmp;
}
public void run() {
if (mSocket == null) {
mMessage = "failed to get a socket";
mHandler.post(mRunnable);
} else {
if (!mSocket.isConnected()) {
if (mBtAdapter.isDiscovering())
mBtAdapter.cancelDiscovery();
try {
mSocket.connect();
} catch (IOException e) {
mMessage = "failed to connect";
mHandler.post(mRunnable);
shutdown();
return;
}
}
// Get the BluetoothSocket input and output
streams
try {
mInStream = mSocket.getInputStream();
mOutStream = mSocket.getOutputStream();
} catch (IOException e) {
mMessage = "failed to get streams";
mHandler.post(mRunnable);
shutdown();
return;
}
byte[] buffer = new byte[1024];
int readBytes = -1;
try {
readBytes = mInStream.read(buffer);
} catch (IOException e1) {
mMessage = "failed to read input
stream";
mHandler.post(mRunnable);
}
if (readBytes != -1) {
// construct a string from the valid
bytes in the buffer
String message = new String(buffer, 0,
readBytes);
// listen for challenge, then process a
response
if ((message.length() > 10) &&
(message.substring(0, 9).equals("challenge")))
mChallenge =
message.substring(10);
write(mState);
}
}
shutdown();
}
