# DavisRFM69: receiving the reverse-engineered Davis ISS radio protocol

> DavisRFM69 receives weather packets from the Davis Instruments Integrated Sensor Suite over its reverse-engineered radio link. The Arduino library adapts RFM69 hardware to the ISS transmissions and includes a Vantage Pro2 console emulation example for Cumulus weather software.
