@Rob-Verhoeff said in communication system:

On AliExpress, you can buy a Bluetooth button that can serve as a push-to-talk key. Press the button, and you're ready to transmit.

I have bought two of these:

(common CR2032 batteries not included)

They seem to work fine. You can even use multiple buttons for multiple groups.
Button A to talk only to the front driver
Button B to talk to the whole group
Button C to talk to the homefront
🤣

Of course for Zello every participating phone needs to have an internet connection, but you can use multiple phones on one hotspot 😉
