Chromecast and Bluetooth options?
If I'm using this through my home stereo, and controlling with my iPad, can I still use bluetooth speakers at the same time?
If your bluetooth speakers have an "audio in" port (mine do), then yes you can plug a Chromecast Audio into them and have it synchronize with your home stereo (that's what I do in my house). That being said, I don't think you can simultaneously play from the same iPad via bluetooth (that is, connecting with your BT speakers over BT and not using a Chromecast Audio) and Chromecast at the same time (at least not without a weird delay).
