gr-ieee802-15-4

Out-of-tree GNU Radio module available in GNU Radio World

gr-ieee802-15-4 implements low-rate wireless personal-area networking for GNU Radio, centered on the physical layer used by Zigbee and sensor networks. It combines O-QPSK and chirp-spread-spectrum modulation chains with packet framing, burst control, and a lightweight Rime networking stack so complete radio links can be assembled from application data down to samples. The module supports interaction with Contiki and TelosB devices and can forward decoded IEEE 802.15.4 or Rime packets to sockets and Wireshark for application development and protocol analysis.

Example flowgraphs

These GNU Radio World examples contain one or more blocks from gr-ieee802-15-4.

• IEEE 802.15.4 CSS Codeword LoopbackMaps bits to CSS codewords and decodes them by minimum distance with gr-ieee802-15-4.
• IEEE 802.15.4 QPSK Phase LoopbackMaps all four QPSK symbol pairs to phase and recovers their I/Q values with gr-ieee802-15-4.
