As part of Google I/O we learned a little something about existing Google Home devices, they have Bluetooth! Announced during the Keynote the Home is getting Bluetooth support. That means it’s yet another speaker you connect to via Bluetooth because we needed more of those, but it’s one thing that the Echo had over the Home. Now that advantage is gone as was about everything else the Echo had over the Home.
Now just to clarify, Google Home will be able to be a Bluetooth speaker, so Music apps without the Google Cast/ChromeCast capability can still be played on the speaker. Not a sender like a phone or tablet would be so no speaker to speaker connecting, also I’m unsure how such a thing would work. The update should be here in the coming months and Google will be reminding us when it’s live for Home users.
