Processing example: "XBee fails to initialize"

[shrestsn]

I ran the example code provided in the Processing wiki.
http://code.google.com/p/xbee-api/wiki/Processing

I got the following error that suggested enabling API mode.

XBee failed to initialize
com.rapplogic.xbee.api.XBeeException: AT command timed-out while
attempt to set/read in API mode. The XBee radio must be in API mode
(AP=2) to use with this library
at com.rapplogic.xbee.api.XBee.doStartupChecks(XBee.java:124)
at com.rapplogic.xbee.api.XBee.initConnection(XBee.java:170)
at com.rapplogic.xbee.api.XBee.open(XBee.java:142)
at sketch_feb20a.setup(sketch_feb20a.java:73)
at processing.core.PApplet.handleDraw(Unknown Source)
at processing.core.PApplet.run(Unknown Source)
at java.lang.Thread.run(Thread.java:662)


So, I added the following line of code to enable API mode only to get
the same error mentioned above.
xbee.sendAtCommand(new AtCommand("AP", 2));

Is it a connection problem with the XBees or am I missing something on
the coding side?

You can't use API mode to put the radio in API mode. The radio by default is in AT mode and you can simply open a terminal to your radio and set AP=2. Only if this is a series 1 radio. If series 2 then you need a firmware update
