Arduino Mega with NRF24L01+ and NRF24L01+ with Atmega328p

Using Arduino Microcontrollers

Unfortunatly i'm back with some bad news :S

first of all, ill post my code on each side then the connections...

Results:

On Arduino (tx)

with CE on 53 and CSN on 49

RF24Network/examples/helloworld_tx/
Sending...failed.
Sending...failed.
Sending...failed.

only with CSN on 49

Sending...RF24Network/examples/helloworld_tx/
Sending...failed.
Sending...failed.
Sending...failed.

Without CE or CSN

RF24Network/examples/helloworld_tx/
Sending...ok.
Sending...ok.

Something must be wrong and im too blind/newb to see. Maybe the pins on ATMega328p (breadboard)? maybe arduino? maybe both?

I tried to be as explicit as possible and btw, the code was from RF24Network for Wireless Sensor Networking | maniacbug

Thanks in advance
