Bought the pro 900 telemetry kit from DIY for my APM2, but no luck getting them to communicate. Both XBee's communicated fine with X-CTU, setting baud to 57600 and a VID to 989. I even re bricked them and successfully upload new firmware and reset the baud and VID again. Read show all the proper settings as well. The Extreme board is set to master. So here's the sequence for blinky lights it that help lol!
Plug in the base side (usb adapter board) and the rx and tx give a couple amber flashes while the blue power led stay on.
Turn on the air side, blue power comes on steady and 1C flashes then goes out. At the same time the base side turns on the red rssi led then goes out. Now all that's lit on both sides are the blue power leds.
In the flight planner I select 57600 and the appropriate com port and hit connect. The red rssi come on steady and the 1O flashes on the air side.
Finally it times out and I get the "No heartbeat packets received". Even tried it outside for GPS lock and the error details said that could be a problem.
Any help for the XBee newb?

You're not connected. You need the RSSI leds on both on. What is the function set (in xctu) loaded on your xbees?
You can always run the serial port test app, though it will blow away your firmware and you'll need to reload. Yes, in xctu, make sure the is modem XBP09-DP and the function set is XBEE-PRO 900 and version is the latest number (1061).
I run digimesh on sparkfun boards, which works fine here (if you want to convert, let me know)--it's XBP09-DM/XBEE-PRO DIGIMESH 900/8062. If you have the XbeePro 900 or digimesh, you can load the digimesh firmware (same transceiver)--digimesh is a bit slower but more robust and easy to setup.
