troubleshooting RF24

Hello everyone,

hope someone here could help me get started with this. I have looked trought topics that are already opened but I haven't what's bugging me.

So I have two arduinos and rf24 modules, and I wanna get started using TMHr20-s library from github. I have downloaded zip, imported it into arduino libraries and I can now open it from arduino.

It compiles without error, and then my problems start.

I want to use "GettingStarted" example to test rf24. I upload program into 2 arduinos, and by pressing "T" i switch one to transmission mode.

When rf24 is in receive mode, he just prints :

Sent response 0
Sent response 0
Sent response 2147483647
Sent response 0
Sent response 0
Sent response 4294967295
Sent response 0
Sent response 0
Sent response 0
Sent response 0
Sent response 0
Sent response 0
Sent response 4294967295

and so on

when I press T ( both arduinos working) , i get this:

Now sending
Sent 18400, Got response 0, Round-trip delay 10012 microseconds
Now sending
Sent 1029928, Got response 0, Round-trip delay 19124 microseconds
Now sending
Sent 2050660, Got response 0, Round-trip delay 19016 microseconds
Now sending
Sent 3071300, Got response 0, Round-trip delay 19012 microseconds
Now sending
Sent 4091940, Got response 0, Round-trip delay 19060 microseconds
Now sending
Sent 5112616, Got response 0, Round-trip delay 19068 microseconds

However, when I turn off receving arduino, he doesn't say about any failures, just keeps get respones.

Any idea what I did wrong?
