In my app, I scan low energy Bluetooth for specific service uuid 2415. To convert the string 2415 into uuid I am using UUID serviceUUID = UUID.fromString(
Hope this will help
To Convert short hand 16-bit uuid to 128 bit uuid you can use this template "0000XXXX-0000-1000-8000-00805F9B34FB". here replace XXXX with your 16 bit uuid.
For example:
In your use case 128 bit UUID will be "00002415-0000-1000-8000-00805F9B34FB".
and to get UUID from string you should use code like this UUID uuid = UUID.fromString("00002415-0000-1000-8000-00805F9B34FB");
