2.3 MICROCHIP MiWi™ PROTOCOL

The MiWi Wireless Networking Protocol is a simple protocol designed for low data rate,

short distance, low-cost networks. It is an application layer on top of the IEEE 802.15.4

MAC and PHY layers. The MiWi protocol provides an easy-to-use alternative for wire-

less communication. In particular, it targets smaller applications that have relatively

small network sizes with few hops between nodes. The MiWi protocol runs on a variety

of Microchip PIC microcontrollers in the PIC18, PIC24 and PIC32 families and the

MRF24J40 2.4 GHz RF Transceiver.

The software stack is available on the PICDEM Z CD-ROM. Check the Microchip web

site for the latest revision http://www.microchip.com/wireless/. Once the software stack

is installed, the source code and documentation are available at:

C:\Microchip Solutions\MiWi\

To load and run the MiWi Protocol demonstration program, please refer to the “Getting

Started: Running the MiWi™ demo” document located in the above directory.

Complete documentation is available in application note AN1066, “MiWi™ Wireless

Networking Protocol Stack” (DS01066).

2.4 MICROCHIP MiWi P2P PROTOCOL

The MiWi Peer-to-Peer (P2P) protocol is an application layer on top of the IEEE

802.15.4 MAC and PHY layers that supports peer-to-peer and star topologies. It has

no routing mechanism, so the wireless communication coverage is defined by the radio

range. Application note AN1204, “Microchip MiWi P2P Wireless Protocol” describes

the MiWi P2P protocol. It details the supported features and how to implement them.

Simple application level data structures and programming interfaces are also

described. The MiWi P2P protocol runs on a variety of Microchip PIC microcontrollers

in the PIC18, PIC24 and PIC32 families and the MRF24J40 2.4 GHz RF Transceiver.

The software stack is available on the PICDEM Z CD-ROM. Check the Microchip web

site for the latest revision at http://www.microchip.com/wireless/. Once the software

stack is installed, the source code and documentation are available at:

C:\Microchip Solutions\P2P\

To load and run the MiWi P2P Protocol demonstration program, please refer to the

“Getting Started: Running the MiWi™ P2P demo” document located in the above

directory.
