To test with this example, please download nRF Beacon app (available both iOS and Android). In the nRF Beacon app, add beacon by pressing the "+" and then select " Add Another Beacon". You need to select the UUID as 0x0112233445566778899aabbccddeeff0, major value 0x1122 and minor value 0x3344. These are the default [UUID, major value, minor value] settings in this example.
