krakentom / GarminSpotifyRemoteController

Project to control Spotify on Android from Garmin Edge 530.

GarminSpotifyRemoteController

How it works

The Garmin application sends commands such as "play/stop," "next song," "volume up," "volume down," and "add to library" to the phone and waits for a response. The phone sends information about the currently playing track back to the Garmin application. The Android app uses the Garmin Connect IQ SDK to communicate with the Garmin device and waits for commands from it. When a command is received, the app calls the appropriate function through the Spotify SDK to control Spotify.
