Bluetooth Scan & Pairing

1. Pairing Complete

   • Once pairing is successfully completed, Qudelix-5K Connected ⓘ will appear under MY DEVICES, as shown in the image below.

iOS Bluetooth Paired Device

Displaying as Connected ⓘ means the device is recognized as an audio device. If it only shows as Connected without ⓘ, it indicates that the Qudelix iOS app is connected to the device via a BLE (Bluetooth Low Energy) link. For more details, refer to the iOS app connection section.

iPhone Bluetooth Scanning Issue

In some cases, iPhones may temporarily fail to scan for or discover nearby Bluetooth devices. This is a known iPhone/iOS issue and is not specific to Qudelix.

If the Qudelix device does not appear during Bluetooth scanning, turn Bluetooth OFF on your iPhone, wait a few seconds, and then turn it back ON. This refreshes the Bluetooth scanning process and usually resolves the issue.
