In my
last article, I pretty hard turned off those who wanted to know what XBee is and how to work with XBee by sending them to Google. I
am correcting myself , because I found an excellent report in Russian on the site
NetMF.ru . Speaker - Peter Alekseev.
PresentationExamplesRecord of the report (11 parts, the last three parts - questions and answers)
Most of the report is a fairly detailed description of the ZigBee protocol, a detailed tutorial on what and how to connect, programming modules, tests, using X-CTU, and so on. You can start listening without having any knowledge of these technologies at all.
In addition to the author's website there is still a lot of information on using .NET MF. Good luck!
