Delta / Mbed OS Delta_BLE_iBeacon Featured

iBeacon example code for Delta module

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.
