twentytheone: im trying to make a network with 3 Nrf and 1 Nrf...
Are you? Why do call one of the nRFs server? I miss a description of all the used hardware, 4 connection descriptions/diagrams, 4 sketches, a description of the problems you encouter, ...
For a basic start I recommend Nrf24L01-2.4GHz-HowTo
I got my nRF24s working with this Tutorial (Same link as @Whandall)
I suggest you use the TMRh20 version of the RF24 library - it solves some problems from the ManiacBug version
The pair of programs in this link may be useful. They can easily be extended to work with several slaves.
