The microchip mrf24j40ma is an 802.15.4 module, with a SPI interface. It's nice and cheap, and it is
|
||||
readily usable on a breadboard, unlike xbee modules. More information here:
|
||||
http://www.microchip.com/wwwproducts/Devices.aspx?dDocName=en535967
|
||||
|
||||
This library provides a basic interface to send and receive packets using plain 802.15.4. beacon mode
|
||||
is not supported.
