Hi, I'm using two Xbee S2, one as coordinator(API) and the other as router(AT). I am trying to send data form coordinator to router, (LED switch that turn on and off) but the delay is unreasonable(~10s). I have increased the baud rate to 115200 and still no change. I am using digital pin 3 on router and set to default. D3 is connected to the LED. I am using arduino UNO as my platfrom.
