_x000D_ _x000D_ I'm trying to setup a simple wireless link between two Arduinos, using two XBee modules and the XBee shield. I configure the coordinator with: ATID 2001 ATDL 4079D623 ATDH 0013A200 and the end device with ATID 2001 ATDL 4079D621 ATDH 0013A200 I then upload simple code to the two Arduino platforms. On the end device: #include SoftwareSerial xbee(2, 3); // RX, TX void setup() { Serial.begin(9600); xbee.begin(57600); } void loop() { xbee.write("A"); delay(500); } and on the coordinator: #include SoftwareSerial xbee(2, 3); // RX, TX void setup() { Serial.begin(9600); xbee.begin(57600); } void loop() { Serial.write(xbee.read()); delay(500); } But no data is passing from the end device to the coordinator. Am I missing something obvious?

_x000D_ I haven't worked with Zigbees since college, but I think you might have mixed up your addressing modes. There's local addressing and there's global addressing. For local addressing, ATDH should be set to 0. You only have to specify ATID, ATMY, ATDL. When using global addressing, on the other hand, you have to specify ATID, ATDL and ATDH. See this thread explaining how to connect to XBee modules over at electronics.stackexchange.
