Android Bluetooth Connection - Service Discovery Failed
android, bluetooth, ioexception, java, sockets
Solution
I don't know and I still don't understand the UUID stuff but the problem was the UUID. I'm using the UUID which I got from the kernel logs and it is `00001105-0000-1000-8000-00805F9B34FB`.
Problem
I'm trying to create a basic bluetooth application, for testing the device. I got the code from developer.android. Here is the link : http://developer.android.com/guide/topics/connectivity/bluetooth.html#ConnectingDevices Here is run part of my thread code: ``` public void run() { mBluetoothAdapter.cancelDiscovery(); Log.i(TAG, "Discovery Cancel!"); try { Log.i(TAG, "Connection Started"); mmSocket.connect(); Log.i(TAG, "Connection Ended"); } catch (IOException e) { try { Log.e(TAG, "Connection Failed", e); mmSocket.close(); } catch (IOException e2) { Log.e(TAG, "Connection Close Failed", e2); } return; } ``` Whatever I have tried `mmSocket.connect();` never works. Always throws an IOException and I get that log from my logcat: `java.io.IOException: Service discovery failed at android.bluetooth.BluetoothSocket$SdpHelper.doSdp(BluetoothSocket.java:403) at android.bluetooth.BluetoothSocket.connect(BluetoothSocket.java:213)` I've looked at these articles, and tried the written things, none of them has solved my problem. Android Bluetooth: Service Discovery Failed, connection to Desktop/Laptop Service discovery failed exception using Bluetooth on Android Bluetooth connection on Android ICS not possible Android Bluetooth java.io.IOException: Connection refused? Btw I'm working on android ics 4.0.4. I know that is not device problem, cause I've tried this app on different devices.
