You can connect two devices to the Logitech Bluetooth Speaker Adapter at once, but only one device can stream to it at a time. The adapter will also prevent a device on standby from taking over the connection while the active device is streaming.
To stream from the device on standby:
Pause or stop the stream from the active device.
Begin the stream from the standby device.
NOTE: The previously active device will now be on standby.
For help with connecting an additional device, see answer 360023421413.
