Hi All:

   I am the newbie and here again.

   This time I have an Xbee connection failure.

   I use xbee pro 900 wire antenna and an adafruit adapter board on the arducopter side, along with an xbee Pro 900 RPSMA.  I setup the Xbee modules according to the wiki through using X-CTU. The result is the same as what it should look like  as in the wiki.

  But the connection does not work at all when I test it. Nothing comes from the serial port monitor of arduino IDE. I am sure the port is correct.  Nothing comes when I use the test demo code either. 

 Can anyone help? Thanks.
