title: Android can't find any BLE devices
body: <p>Here's he problem. I've developed an app for iOS to control an BLE LED device (and a few other things). Everything works fine and smooth. Now I wanted develop the same app for android and I already fail at the scanning of BLE devices. I have tried a few tutorials and sample codes but whatever I do I can't find any devices. I work on a Moto G4 Play. The bluetooth works and I can pair devices in the settings but it won't work with any sample code/tutorial I've tried.
  For example this one:
  <a href="https://github.com/kaviles/BLE_Tutorials" rel="nofollow noreferrer">https://github.com/kaviles/BLE_Tutorials</a></p>
  
  <p>I build this app as it is and it can't find anything.</p>
  
  <p>So I downloaded a BLE Scanner from the Playstore and that works fine to and finds all devices.</p>
  
  <p>I know it's hard to say without any sample code but I've tried so many and I'm not sure if I miss something completely basic.</p>
