How to stream audio through to different devices? (bluetooth?)

Hello, I searched on the communitiy without success and I would like to make some offline audio transmitter, like a multi walkie talkie.

I need to transmit my voice (via bluetooth?) to several phones connected.

How can I do that?
Haw can I do that with bluetooth?
Thanks

Hey @trawellit

At the moment our BLE component only surrports text transfer (to the best of my knowledge).

Do you have to use Bluetooth for this project? If you’re creating something like a walkie talkie then perhaps the MediaDB would be a better component for this project?

I would like to use bluetooth because it does not use internet connection, cloudinary instead needs connection.

Is there a way to transmit audio in real time offline?
