end point device response to coordinator through serial port

Hello it's me again :smiley:

i have 2 xbee pro "s2b" and configure one as coordinator and the other one as end point.
i have send to the end point H to light up an led and L to turn it off.

i want to make a response such as if i send H to the end point the led is On then it's replay to the coordinator to say i have turned the led and if the End point receive L the led is turn of and replay i have turn it off

i have Serial.print("LED OF")
but it dosn't work
guide me please

Sorry, but my crystal ball has crashed and I can't see your code.

Have you first gotten your code to work just using wires between the two arduinos without using the xbees? That would be the first thing to work out.
