Programmable beacon payloads
In some implementations, a beaconing protocol can be used to broadcast beacon information to mobile devices. The beaconing protocol can be used by a Bluetooth Low Energy (LE) (e.g., Bluetooth 4.0) beacon to transmit a package of information that identifies the beacon and indicates the calibrated transmission power (e.g., measured power) of the beacon. The package of information can be configured by beacon providers and/or beacon installers at the locations where the beacons are installed. When a mobile device receives the beacon package, the mobile device can use the beacon identification information and/or the measured power of the beacon to determine a location (e.g., precise location, geofence location) of the mobile device. In some implementations, the mobile device can transmit the beacon information to a server and the server can determine the location of the mobile device and send location and/or content information back to the mobile device.
