CHOE86:
my project. I want to send the temperature sensor data and humidity of the room to the master node -> master node receive and store sensor data. then the master node sends a command to the slave node to turn on the light -> slave node receives commands from the master node and turns on the light.
You still have not answered my question which you quoted in your Reply #5
The piece of text that I have quoted in this Reply suggests that you just need simple communication between a master and a slave. That can be done without using the RF24 Network library. There is an example of doing it in the Tutorial I linked to in reply #1
