RF24Network and nRF24L01+ (send a string)

Grag38:
Nice ! You got it.

Have pleasure working with these marvellous modules that are NRF24. I use them until 80 meters far and it works great !

Actually I'm using these modules (I have 6 of them, 2 in test) without external antenna, downgraded to 250KB speed.
Could you explain me a little bit how have you designed your network?
I would like to have a central station that could receive sensor status from the leaves (and this now works) but the same time that could send messages to them in case I would like to turn on/off a relay or whatever.

Thank's!
