RAVE is an Android application that provides text communication via peer-to-peer Bluetooth and data connections. Multiple RAVE devices can form a multi-hop network capable of extending communication over longer distances. The next step for the application is to add push-to-talk audio messages.
RAVE’s range can be extended via a network of relay nodes. These inexpensive single-board computer devices communicate over non-line-of-sight radio frequencies to greatly increase the range of messages.
RAVE is built on the Clatter platform. Comprehensive documentation on Clatter's features and architecture, as well as the integrating it into other applications, can be found here.
The Android application for RAVE is still under active development, but will be available soon. Development information and status is on the wiki.
The RAVE Relay is designed to run on a Raspberry Pi in order to serve as a relay to propagate RAVE messages over long distances.
