About this app

YAMA connects your smartphone to a MeshCore radio via Bluetooth, turning it into a fully functional off-grid messenger. Messages are transmitted over the LoRa mesh network – completely without internet, cellular networks, or central servers.

Important: YAMA is a companion app and requires a compatible MeshCore device (LoRa board with MeshCore companion firmware). Without such a device, the app cannot send or receive messages.
