Blutooth Le Scan

Solution 1:

The Problem there is that you are trying to use

startLeScan(callback) 

without setting the Uuid parameter. So the BluetoothAdapter code it's doing something like:

startLeScan(null, callback) 

on the back and printing

"startLeScan:" + Uuid. 

Which for you is null.
