title: Having trouble with custom UUID in Android BLE
body: <p>I have a problem with using my own generated UUID(not using 16 bit UUID reserved by Bluetooth SIG) to communicate in Android BLE.</p>
  
  <p>Target device is two - one is as a peripheral(Samsung galaxy note 4/android 5.1.1) and another one is as a central(Samsung galaxy S5/android 5.0.1). I put my own service's UUID and characteristic's UUID on the peripheral side. On the central side, it could not find characteristic but service.</p>
  
  <p>It seems like it caused by not using one of <a href="https://developer.bluetooth.org/gatt/characteristics/Pages/CharacteristicsHome.aspx" rel="nofollow">these Characteristic UUIDs</a> but using custom generated UUID.
  Below is my own generated UUIDs.</p>
  
  <pre><code>private static final UUID CUSTOM_SERVICE_UUID = UUID.fromString("abcd1111-0000-1000-8000-00805f9b34fb");
  private static final UUID CUSTOM_CHARACTERISTIC_UUID = UUID.fromString("abcd1112-0000-1000-8000-00805f9b34fb");
  </code></pre>
  
  <p>Service, found well, but characteristic, no.
  Do you have any idea?</p>
