•The Qudelix App has nothing to do with Bluetooth Audio Streaming. You can get audio streaming over
Bluetooth without Qudelix App. However, we strongly recommend installing and using the app to
experience the feature-rich nature of Qudelix-5K fully.
•5K allows the APP connection with one device at a time.
•Android App uses the BR/EDR link. So, Android requires the 5K device paired to the system before
making the app connection.
