I have recently bought two nRF24L01+ modules (http://www.sparkfun.com/commerce/produc … cts_id=705). Both modules are connected to a Arduino board. I use this library to control the modules (http://www.mrroot.net/wp-content/upload … 1/Mirf.zip).
One board is acting strange: When I want to send some data from one Arduino to the other nothing happens but when I grab one of the module’s wires it starts sending data (distorted). When I take my hand of the wire sending stops?
I already figured out this happens only with one board, the other board is working fine. The boards are totally new and never used before. I only soldered the headers one some time ago?
Could this be a ground or some kind of capacity problem? How can I check this?
Is there a way to check if I soldered the headers right? I soldered them according to a previous post (viewtopic.php?f=13&t=21286)
I am already 2 days trying to get this working and I am totally lost.
Suggestions are highly appreciated 
Thanks in advance!!
