How to send data using XBee S2C and Arduino


I want to send data between two Arduino UNO with XBee S2C modules. The XBee modules are configured with the same Pan ID and API 2 mode. One of them as a Coordinator and the other as a Router. In XCTU I can prove that the XBee are connected.

In the Arduino board I’m using the xbee-arduino library ( and I’m running the Series 2 example but my Arduino with de router XBee, blinks twice the led builtin which tells me that the local XBee is not providing a response.

To connect the XBee and the Arduino, I’m using an Arduino Wireless SD Shield and I’ve tried to connect the XBee directly to the Arduino, getting the same result.

Hope you help me, and sorry about my English. Thanks!.
