The Beolit 17 remembers up to 8 Bluetooth pairings, so as soon as an already paired device is within range, you can just connect to the speaker and play from your device.
However, only two devices can be connected at a time. To connect a third device, you must disconnect one of the first two. When the speaker starts up from standby, it will connect to the last used device again if it is within range and Bluetooth is active.
When you pair a 9th device with your Beolit 17, it will automatically delete the profile of the device used less recently.
If the above does not work, then remove your Bluetooth speaker from the device list and make a new pairing.
