Chrome App that advertises a different URL depending on the image. Uses the Eddystone Advertising library available here.
BLE Advertising is only available in Single App Kiosk Mode.
For development you should turn on the enable-ble-advertising-in-apps
flag in chrome://flags/#enable-ble-advertising-in-apps. This will let
the app Advertise without being in Kiosk Mode.
For deployment you should add the following to manifest.json:
"kiosk_enabled": true,
"kiosk_only": true
