Dead XBee?


I have ordered 7 pieces of XBee-Z7WIT.

But my problem is that 2 of them are not working.After connecting to PC the X-CTU is not able to do a “TEST/QUERY” or to write a firmware.

What steps should I do to detect if they are really dead or if there is just some glitch?

I am using XB24-Z7WIT with Sparkfuns Diprotodon as USB/Serial and the newest X-CTU on Windows 7.Thank you for every answer.

Make sure you are not using the 2xA0 firmware - XCTU should offer you the newer 2xA7.

Sometimes you need to exit XCTU and restart it when changing XBee. Make sure your pins or the socket on the Sparkfuns USB unit are not damaged.
