# Android App Connection

Using the dedicated Qudelix app, you can perform firmware updates, configure features, and set up EQ for the Qudelix 5K.

The Qudelix mobile app is not related to Bluetooth audio streaming. Even without the Qudelix app, the device functions like a standard Bluetooth audio device, supporting HFP calls and A2DP audio playback.

{% hint style="info" %}
Only supported on Android 8.0 and above.

## Connecting

The Android app uses a Bluetooth BR/EDR link. Therefore, the Qudelix 5K must be paired with the smartphone before connecting through the app.

You can manage device connections and deletions under the menu **App → Device → Connection**.

When the app is connected to the 5K device, the underline bar at the top of the app, indicating the selected tab, will be displayed in red. A gray bar indicates that the connection is disconnected.

Notic&#x65;**:**

The 5K supports multipoint pairing and can connect to two smartphones simultaneously. However, the app connection supports only one device at a time. When using multipoint pairing, if you want to connect the app to another smartphone, you must first disconnect the existing connection by closing the Qudelix app on the current smartphone.
