Hello all,
I've had problems since several weeks with RF24 Library (enhanced fork). I know very well different documentation, and I read a lot on different forums. But It doesn't work anymore !!
My goal is to have a master which communicate with two slaves. Each have different adress and different pipes.
I have a lot of loss (only 60 % works)
Here is master software :
but I have this result:
