Using the nrf2401a with library provided on arduino site

Hi,
Just a n00b trying my hand with it. I downloaded the zipped library file from Arduino Playground - Nrf2401

and am using the test code provided, but I can't get them to work. Any help on troubleshooting ideas would be great. Thanks

"can't get them to work" is a little vague. Are you getting any specific error?

Thanks for the reply. It compiles smoothly and uploads as well, but the receiver is supposed to have the LED 13 blinking. No blinking -> transmission unsuccessful. I did the connections as instructed on the page. Double checked it was always 3.3V

Hey, I'm using the NRF2401A Transceivers from Sparkfun as well. I'm just wondering if there is any way to increase the transmission range, currently only getting about 6ft transmission range.

if you change the data rate to 250kb, it should give you a small increase to about 12ft to 17ft. and make sure you are using the highest antenna power setting. (can't remember it off the top of my head) but it's on the data sheet. (if u are using the arduino library, then that part is covered). but u still need to change to 250kb in the library.

Thanks, I'll give that a try and see how it works.

Ok, I whipped up a tutorial on using these radios on my blog at: Getting Started with nRF24L01+ on Arduino | maniacbug . I tried to keep it as simple as humanly possible and still use the radio. Hope it helps you guys.
