I am really starting to think that my smartphone is being listened while not being used. I do not like this, so I want to use a Raspberry Pi Zero W with a USB microphone as a repeater, connected to a bluetooth speaker.
The purpose is to keep the RPi (with USB microphone) and smartphones at a remote place in house, while the bluetooth speaker warns me if any smartphone rings, so I can answer.
Does anyone know if there is some easy script for this?
