🌀 Android Beacon Scanner

A simple android beacon scanner that can recognize iBeacons, AltBeacons, Eddystone beacons (UID and URL, with or without TLM) and RuuviTags available on Google Play.

Available for android 5.0+ and smartphones with Bluetooth LE.

🔑 Features

This app will scan for beacons near you! ✌️

For all Beacons:

  • The type of beacon (iBeacon, AltBeacon, Eddystone or RuuviTag)
  • The approximation of the distance with the beacon (this is based on the RSSI value received and is NOT accurate)
  • The beacon address and manufacturer code
  • The RSSI and TX values
  • The last time the beacon has been seen

For iBeacons and AltBeacons:

  • UUID
  • Major
  • Minor

For Eddystone-UID beacons:

  • NamespaceID
  • InstanceID
  • TLM data sent if any

For Eddystone-URL and RuuviTag

  • Clickable URL
  • TLM data sent if any

For RuuviTag:

  • Air Pressure
  • Temperature
  • Humidity

It can display several frames emitted by a single beacon, allowing you to see if a beacon emits multiple frames types (for example radius network beacons can emit iBeacon and AltBeacon at the same time)!

  • You can also log the scans of the beacons to an endpoint via a HTTP POST request.

🔧 Installation setup

  1. This project uses Firebase Analytics and Firebase Crash reporting, therefore it needs a google-services.json files in the app directory. To get it you need to create a Firebase project in the Firebase console and go to the project settings and download the google-services.json file from there.
  2. You'll see there is a signingConfigs.release in the app/build.gradle that contains variable that you didn't declare beacon_scanner_key_password, beacon_scanner_store_file, beacon_scanner_store_password. Either you create those 3 keys in your ~/.gradle/gradle.properties files or you can simply remove this configuration if you're not interested in having a release signing configuration. Make sure to remove it in the release and preRelease buildTypes as well.
  3. That's it, the app should now compile!
