I can't for the life of me figure out how to connect this setup. I have four XBEE SE PRO S2 T's, two Arduino Uno's, and two Arduino shields. I have XCTU and programmed one as the coordinator and the others as one router and two end points. Now the problem is the end devices go unresponsive as soon as I upload the firmware in XCTU, but the coordinator and router stay on just fine. I have changed the sleep setting to the max and they still do the same thing. I also maxed out the baud rate and still no luck. All I want to do is turn on an LED... Such a big problem for such a simple task. Anyways any help would be very much appreciated. I have attached the code and the hardware so you can see what i'm working with. Thanks!20160404_112737.jpg 20160404_112748.jpg 20160404_112737.jpg 20160404_112748.jpg

void setup()

void loop()
int data =;

  case '0':
  digitalWrite(7, HIGH);
  Serial.println("LED turned on");

  case '1':
  digitalWrite(7, LOW);
  Serial.println("LED turned off");
