UAT Test App

The flinkey UAT Test App is a pre-built Android application that lets integration partners test the full vehicle access flow without building a mobile app first. It connects to the UAT environment and supports all standard BLE operations including Box Commands.

Caution

This app is for development and testing only. Do not distribute it to end customers or use it in production environments.

Download

⬇ Download flinkey UAT App (Android)

Platform	Android (ARM64)
Version	3.6.0 (Build 87)
Environment	UAT
Package	digital.witte.flky.mobile.droid.app.uat

An iOS version is currently not available as a pre-built binary. iOS partners can use the witte-mobile-sample-ios repository to build their own test app.

Installation

Enable Developer Mode on the Android device

1. Go to Settings → About phone
2. Tap Build number 7 times until “Developer mode enabled” appears
3. Go back to Settings → System → Developer options
4. Enable USB debugging

Install via ADB

Connect the device via USB, then run:

adb install flinkey-uat.apk

Install directly on device

1. Transfer the APK file to the device (USB, email, cloud storage)
2. Open the file on the device
3. Allow installation from unknown sources when prompted
4. Complete the installation

Prerequisites

Before the test app can be used, the following must be in place:

• Active partner account on UAT (flinkey Portal)
• At least one car created via the flinkey API
• At least one user created via the flinkey API
• An active assignment linking the user to the car (webhook confirmed)
• A flinkey BLE Box installed in the test vehicle

    app-->>dev: Show result

Step by step

1. Create the access context — Use your partner backend to create a car, user and assignment via the flinkey API (UAT). Wait for the assignment webhook.
2. Log in — Open the test app and log in with your UAT user credentials.
3. Sync keys — The app automatically syncs digital keys from the Tapkey server.
4. Find vehicle — Your assigned vehicle appears in the vehicle list with a green key indicator.
5. Test BLE access — Move close to the vehicle’s BLE Box and trigger unlock/lock.
6. Verify feedback — The app shows the box response (lock state, battery level).

What you can test

Capability	Supported
Vehicle list with key status	✓
BLE discovery and connection	✓
Unlock / Lock (standard toggle)	✓
Box Commands (unlock car, lock box, status)	✓
Box feedback (battery, drawer state)	✓
Multiple vehicles	✓
Assignment lifecycle (create, update, delete)	✓

Limitations

• UAT only — The app connects exclusively to the UAT environment
• Android only — No iOS binary available (use sample repo instead)
• No customization — The app uses the standard flinkey UI, not your partner branding
• Version fixed — The APK is a point-in-time build; contact support for updates
• Not for production — Never distribute to end customers

Alternative: Build your own test app

If you need more control or want to test on iOS, use the sample repositories:

• Android: witte-mobile-sample-android
• iOS: witte-mobile-sample-ios

These repositories contain minimal working implementations that you can build and run with your own UAT SDK Key.
