+# Eddystone
+
+Support for Eddystone beacons.
+
+```cards
+eddystone.advertiseUrl("https://pxt.io/", 6);
+eddystone.stopAdvertising();
+```
+
+### Advanced
+
+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.
