Android bluetooth app to connect phone to smart speaker full-duplex?

Question

I'm wondering if anyone knows of an app that will allow an android phone to connect to a smart speaker (like Sonos One) via bluetooth, and have the two devices function like an intercom with full-duplex (2-way) audio. There is an app called Intercom on the Play Store, but it will only connect to another phone, not a smart speaker. There are walkie-talkie apps, but these also connect two phones (and require push-to-talk).

Answer 1

Only the Sonos Move has proper Bluetooth support, and only a few audio profiles. You need to use WiFi, and even then you have no access to the microphone on the Sonos.

Answer 2

Thanks for all the come-backs. If anyone trying to solve this same problem runs across this thread, try searching Amazon for "full duplex wireless intercom." I found eMACROS Portable Wireless Intercom System on there. Sound isn't as good as a Sonos or Echo, but it works.
