>Does that mean I can finally connect to it from my phone via Bluetooth and play music that way?
I don't know about this device, but what you are describing is the antitheses of how chomecast is intended to work (or at least it was, from the beginning of chromecast to the last time I checked).
The idea is that you never stream anything from your phone, but rather your phone is a remote control and service authentication device for the chromecast.
