Communication between two matrix voice

Hello,

I need to make a two way communication between three matrix voice by using HAL. Is it possible? is there any solution available.

Hi @rameelhashmi,

There are no ready-made solutions available.

However, if you are using the MATRIX Voices along with Raspberry Pis, you could use a C++ server/client TCP/IP socket library (a quick Google search should offer many), or even see if MQTT C++ libraries are available. I found this one: https://github.com/redboltz/mqtt_cpp.

If you are using standalone ESP32 MATRIX Voices, we have this Hackster guide that you can modify so they can send/receive MQTT messages to each other over WiFi.

Best,
Samreen
