The Microchip MiWi P2P Wireless Protocol is a variation of IEEE 802.15.4, using Microchip's MRF24J40 2.4 GHz transceiver and any Microchip 8, 16 or 32-bit microcontroller with a Serial Peripheral Interface (SPI).The protocol provides reliable direct wireless communication via an easy-to-use programming interface. It has a rich feature set that can be compiled in and out of the stack to meet a wide range of customer needs ? while minimizing the stack footprint.Microchip?s Application Note AN1204 describes the Microchip Wireless (MiWi) Peer-to-Peer (P2P) Protocol and its differences from IEEE 802.15.4. The document details the supported features and how to implement them. Simple, application-level data structures and programming interfaces also are described.
