For those who do not know what Eddystone is, it is a protocol specification by Google that defines a Bluetooth low energy (BLE) message format that can be utilized for proximity-based beacon messages.
You can use an Eddystone message to broadcast data such as a URL from your Bluetooth device.
Devices running a scanner that can understand the Eddystone protocol will be able to pick up the beacon. In the case of our tutorial, it will allow the user to open the URL that you are broadcasting. In addition to this, the beacon also shows distance data.
