### Eddystone
|
|
|
|
|
|
|
|
|
|
Bluetooth beacons are used to indicate proximity to a place or object of interest.
|
|
|
|
|
Beacons use Bluetooth advertising to broadcast a small amount of data,
|
|
|
|
|
which can be received and acted upon by anyone in range with a suitable device and software, typically a smartphone and application.
|
|
|
|
|
|
|
|
|
|
There are various beacon message formats, which define the way Bluetooth advertising packets are used as containers for beacon data.
|
|
|
|
|
iBeacon is Apple's beacon message format. Eddystone comes from Google.
