The Smart Ultra Soundbar pairs with Bluetooth devices from the Bose app's Source menu or by putting the soundbar in Bluetooth discoverable mode, and its light bar pulses blue when it is ready to connect. When you select the Bluetooth input, the soundbar first tries the last device it connected and then works through the others in order of last use, which can cause a short delay. If a device will not connect, Bose sends you to a troubleshooting article for Bluetooth connection failures and to clearing the soundbar's paired-device memory.

Try in this order
0 of 5 completedChoose the Bluetooth source
ReversibleOpen the Bose app, select the soundbar, tap Source and then Bluetooth. The soundbar tries its last device first and then others in the order they last connected.
Look at the light bar
ReversibleA blue pulsing bar means it is ready to connect a Bluetooth device. White pulsing fast means it is connecting; if the bar is amber, it is in setup mode instead.
Select the soundbar on the device
ReversibleOpen the phone or computer's Bluetooth list and pick the Bose Smart Ultra Soundbar. On a Windows PC choose the entry with the speaker icon, not the one starting LE-.
Clear memory if needed
ReversibleRemove the soundbar from the device's saved Bluetooth list, then clear the soundbar's own list of paired devices from the Bose app and pair again.
Reset
ReversibleTurn the soundbar off, remove power for 30 seconds, restore it and wait about 30 seconds for the reboot before trying again.
Stop boundary
When this stops being a self-service repair
- !If the light bar never pulses blue after a 30-second power reset, contact Bose Support for service
- !If the light bar is solid red, that is a system error listed in Bose's light bar table and needs troubleshooting first
