I ran across this transceiver for $6! 
http://search.digikey.com/scripts/DkSearch/dksus.dll?lang=en&site=US&KeyWords=QFM-TRX1-24G

I did a search for an Arduino library for it and came up empty.

Is anyone up to the challenge?  Sure looks like a powerful solution.

From the data sheet (http://www.quasaruk.co.uk/acatalog/DSQFM-TRX-2.pdf) it looks like it uses an SPI interface and has two extra digital outputs for status signals.  It doesn't say anything about the software protocol but under "References" it says "For detailed specifications on the rf chipset used on this module please refer to the chipcon CC2500 datasheet. www.chipcon.com"  That site says "Due to Texas Instruments' acquisition of Chipcon, the URL that you are accessing has been moved. Please change your bookmark for future reference to TI's Low-Power RF web site.' and then re-directs.  A search gets you to http://www.ti.com/product/cc2500 which points to the datasheet: http://www.ti.com/lit/ds/symlink/cc2500.pdf

Here is a project that includes libraries for talking to the CC2500 chipset:

In theory there is no difference between theory and practice, however in practice there are many...

Hello, has anyone tried using the library cc2500 which john has mentioned in his post? I tried but couldn't get my application working. I want to get data from sensor to arduino wirelessly using cc2500. Can anyone help?
