Just ordered a few of the WickedDevice nodes for comparison. Victor has posted that he will release his source code soon, Huzzah !
WickedDevice is a completely different approach than DCDW, it is more like DCSW "Dirt Cheep SMART Wireless". It listens to the receiver noise as UART serial input and pulls out valid packets from the stream of garbage characters by using CRC and other validity checks. The code development is impressive.
It will be interesting to compare battery life and Arduino resources for our two different approaches. Compared to the "throw Xbee node$$$ at it" approach, either DCDW or WickedDevice should have far longer battery life as well as much lower cost. Maybe somebody using Xbee can post here how long an Xbee node will run on a 9v battery !
Will continue on with DCDW testing and development, v1.0 boards are ready to order, anyone interested in getting some let me know.
