Software RS232 and wireless modules

[Gixxer]

Depending on your application, you might consider trying the Digi Xbee modules. They are super small with excellent range and built in encryption and error checking. They operate in the 2.4ghz band under the Zigbee protocol, 802.15.4. All you do is add 3.3v power, serial TX/RX lines from your pic and you in business, it's that easy. They also use free Digi software(X-CTU) to make any config changes, although they work at 9600 baud right out of the box. I have been playing with these for a little while and am very impressed.

John --

Zigbee seems to be the "new" standard in the neverending saga of wireless.

I bought some of these Xstream 2.4ghz oem modules el cheapo and as it turns out, you use the xctu software and a 60 buck development board from digi key. (have you ever used them?)
(X24-009NSI)

I think I can also use this board (XBIB-R) for doing the zigbee modules?

I'll have to sit down one day and get up to date on the latest and greatest in wireless....
has the dust settled? does zigbee look like something that's here to stay?

Hi Michael

The modules I am currently using with excellent results are called the Xbee Pro, I got mine from Digi at http://www.digi.com/products/wireles...-zb-module.jsp, their shipping is next day and only 8 bucks ! Now you do need some sort of pcb to plug these into as they have a non standard pin spacing of 2mm(won't fit in breadboard). That being said there are alot of interface boards to choose from. I use an great interface that of coure has the requied connectors for the xbee along with a pic 18f2520 running @ 40Mhz. Its an all in one pic/xcvr package, with built in ICSP or serial programming ports. I also use a serial DTE interface board made by the same company, which has built in v/reg, rs232 level shifter and DB9 connector, ready to plug into pc com port, they also have USB. I got mine here : http://microcontrollershop.com/produ...oducts_id=2370 .
And to answer your other question, the Zigbee protocol is here to stay, already being used in a ton of remote sensing and monitoring apps(power,gas and water metering) The IEEE developed the zigbee standard in '04 and revised it in '07, so it IS quite new.
