The Google Home speaker can now act as a Bluetooth speaker. You can connect your iPad, iPod, or other Bluetooth audio source to the Google Home speaker, and then play music on your device, and have it come out of the Google speaker. You can also pair a BT speaker to Google Home. Then any streaming music that would play on the Google Home, now plays on that speaker. It can stream to an external BT speaker, and act as a BT speaker itself, although likely not at the same time.

Does Google Home Speaker have Bluetooth ?
At first, Google offered Chromecast alone on the Google speaker. Chromecast allows you to stream audio and video content from media services to the following.
-
- Chromecast TVs.
- Speakers.
- Other media player devices.
Just as you’d do if your were streaming your media to a plane-Jane Bluetooth speaker. Perhaps they figured that Chromecast would be a decent replacement for generic Bluetooth capability. But you can’t cast content via Chromecast to a speaker that does not support Chromecast.

Fortunately though, Google decided to support both Bluetooth and Chromecast on the same speaker. This certainly adds to the speaker’s usefulness. Why? Because not only can you now stream to Chromecast speakers, but also, to the more common Bluetooth speakers as well.
