+/**
+   @file
+   @brief Example of using the XBeeApi library to receive a message
+          via a callback method
+          This example has a minimum of error checking in order
+          to keep the code compact
+
+          This example shows how to use the library when using mbed-rtos.
+          Before compiling you must open "XbeeApi\Config\XBeeApiCfg.hpp"
+          and change the '#if 0' to '#if 1' on the line above the comment
+          reading "Use RTOS features to make XBeeApi threadsafe"
