I have a Bluetooth speaker with a built in microphone (and also several bluetooth headsets which are essentially the same). I have it paired with my Nexus 5x running Marshmellow. I would like to have a setup such that when the bluetooth device is on and connected, I can speak "OK Google" into the bluetooth device and Google Now activates on the phone.
I am fully aware that I can launch Google Now through a button push on the bluetooth device (albiet the speaker does not have any buttons but power on/off), however, I dont want to have to push any buttons. I want to activate Google Now, through the bluetooth device, hands free.
Note, in the Google Voice settings, I do have "Bluetooth Headset" on and "Hands free for Bluetooth devices" also on.
Is this possible?
