Out of the box, Chatter 2.0 is not compatible with Meshtastic. It uses its own dedicated firmware and communication protocol designed for a seamless peer-to-peer experience between the devices in your kit.
However, since Chatter 2.0 uses LoRa technology, it is possible to make it work with Meshtastic, but only if you are willing to tinker with it.
