@mfalkvidd Thank you! It works.
I was searching for "A0" not the GPIO number (newbie here)

Thank you once again.

Hi,

I'm looking for an anwser but cannot find it anywhere.
Is it possible to change pin from A0 to different one (for example A3) for NRF24l01 in a gateway ?
If yes, where can I defined it ? (it's not defined on my sketches>

Thank you in advance
