I have two simple boards and I want to on/off a channel of one of boards in 5m distance from other board wirelessly and very fast.
The speed of this communication is very important for me.
Can anyone help me?
alireza You misunderstood the post.. 'very fast' is not a number, it has no associated unit of measurment, and no relation... something with a 1 month rotation is 'very fast' compared to the trip the earth takes around the sun.
