Datasheet

Output
You can use the nRF Beacons application from Nordic Semiconductors to test this sketch:
nRF Beacons for iOS (https://adafru.it/vaC)
nRF Beacons for Android (https://adafru.it/vaD)
Make sure that you set the UUID, Major and Minor values to match the sketch above, and then run the sketch at the
same time as the nRF Beacons application.
With the default setup you should see a Mona Lisa icon when the beacon is detected. If you don't see this, double
check the UUID, Major and Minor values to be sure they match exactly.
