Android - Get Bluetooth UUID for this device
up vote 9 down vote favorite 7
|
I was browing Stack and the internet for a simple solution to get the UUID of the device I'm currently using. I stumbled over posts like this but none of them seemed to help me. The doc tells me about this getUuids() function but when going through the doc for Android Bluetooth I end up having a BluetoothAdapter but I need a BluetoothDevice to execute this function. So I need to know the following: 1) Is the function returning really the device UUID? Because the name saids plural (getUuids) 2) How do I get an instance of this BluetoothDevice? Thanks!

Using reflection you can invoke the hidden method getUuids() on the BluetoothAdater: BluetoothAdapter adapter = BluetoothAdapter.getDefaultAdapter();
Method getUuidsMethod = BluetoothAdapter.class.getDeclaredMethod("getUuids", null);
ParcelUuid[] uuids = (ParcelUuid[]) getUuidsMethod.invoke(adapter, null);
for (ParcelUuid uuid: uuids) {
Log.d(TAG, "UUID: " + uuid.getUuid().toString());
}
This is the result on a Nexus S: UUID: 00001000-0000-1000-8000-00805f9b34fb
UUID: 00001001-0000-1000-8000-00805f9b34fb
UUID: 00001200-0000-1000-8000-00805f9b34fb
UUID: 0000110a-0000-1000-8000-00805f9b34fb
UUID: 0000110c-0000-1000-8000-00805f9b34fb
UUID: 00001112-0000-1000-8000-00805f9b34fb
UUID: 00001105-0000-1000-8000-00805f9b34fb
UUID: 0000111f-0000-1000-8000-00805f9b34fb
UUID: 0000112f-0000-1000-8000-00805f9b34fb
UUID: 00001116-0000-1000-8000-00805f9b34fb
where, for instance, 0000111f-0000-1000-8000-00805f9b34fb is for HandsfreeAudioGatewayServiceClass and 00001105-0000-1000-8000-00805f9b34fb is for OBEXObjectPushServiceClass. Actual availability of this method may depend on device and firmware version.
