Implementing Bluetooth iBeacon Beacons on nRF52 #Bluetooth #beacon #NordicTweets @novelbits

As a continuation of Mohammad Afaneh’s series on Bluetooth beacons (part 1 here and part 2 here), a new blog post covering Apple’s iBeacon standard in a bit more detail.

iBeacon is especially useful for deploying location-awareness applications and monitoring user behavior within an area. It was introduced in iOS 7 and utilizes Bluetooth Low Energy (BLE) to send out advertisements that get discovered and utilized by other BLE-capable devices (especially smartphones).

It’s an application layer implementation on top of BLE, so it requires awareness on both sides:

  • Implementing the iBeacon format on a BLE device (normally battery-operated)
  • Implementing awareness of the iBeacon format on another device capable of acting as a BLE scanner (normally a smartphone app)

An example showing how this can be implemented in the field. The example is for a chain of international stores.

  • UUID is common across all stores and defined in the app.
  • Major identifier is assigned to each of the different store locations.
  • Minor identifiers are assigned for regions within the stores
  • UUID, Major, and Minor identifiers are not registered with Apple and are chosen at the developer/manufacturer discretion.

See the full details in the blog post here.
