Hi there!
Has anyone ever tried using these: http://rfm.com/products/data/dnt24p.pdf ?
They sound really interesting, larger distance and lower price than the pro XBees, but it seems less user friendly?
Are they as easy as Serial.write() and .read() (like the XBees)? Do they need configuration (how?)?
Thanks!
Anyone? 
I'm really interested in those (since the performance looks better and the price is low), but I'm afraid I won't be able to use them (how would I configure them?).
I designed them into a couple of boards with IO at users request. I didn't write the software for it tho.
I know we connected both the serial lines and the SPI interface. Didn't connect any of the others - GPIO, ADC, DAC.
There are more detailed documents available than just the one you've linked to. Read them before deciding on whether to connect just one or the other.
Hi CrossRoads, thanks!
Yes you're right, there is this Integration Guide: http://www.rfm.com/products/data/dnt24_integration.pdf
I'm still not sure wheter I will be able to use them. For the XBees, there are loads of tutorials out there, a PC-Software to configure them and after all they're really easy to use. But the distance I need to reach is about 2 or 3 miles, so the XBees won't do it (the one's with a greater distance are limited in use outside of US/Canada).
I think, after all, the only way to find out is to order some and try it..Or are there alternative products?
Don't know. I do know Mouser.com has tons of RF modules, have not really browsed them to see what ranges are possible at what frequencies.
A lot depends on the antenna and on the environment - wide open: good, lots of trees: bad.
Hi,
You're right, CrossRoads, there are tons of RF devices out there. But I'm looking for something easier to integrate in a Arduino-Project, and I won't find something like this, somewhere in a backroom of mouser. .
That's the way to find stuff sometimes - just plow the specs reading their capability.
