hi ı want to create sensor mesh network with three xbees2 as one of coordinator,one of router,one of end device?

ı confıgured xbees using with x-ctu as;

ın this confıuration,there are one sensor in router and end device.ı took apı frame from router but ı didnt take apı frame from end devide.router cant send the end device ınformatıon.
How can you solve this situation?

Are you using hardware flow control on the End device and your device connected to the end device?

ı made cts flow control form digital pın in end device.End devic only connected to sensor.
