For Android

Installation instructions

1. On the tablet, open the downloaded de1app.apk and tap Install. If Android warns about "unknown sources", allow installs from your browser or file manager, then tap Install again.
2. Open the Decent app from your home screen.
3. When prompted, grant the Bluetooth / Nearby Devices and Location permissions. Android treats Bluetooth as a Location service, so the DE1 cannot be found without them.

Alternative: manual Android installation (more difficult)
