automatic update for many XBee or WiFi modules?

Hello,

does anyone know if it's possible to upgrade many XBee Modules or Wireless modules (like the ones from Digi or Atmel) wirelessly?

by experience I know that I need to put XBee in an adapter that connects to pc with serial cable in order to configure Xbee with help of XCTU.. But if I have a big project that contains about 50 Modules (XBee or WiFi), it would be hard to do the upgrade for each module alone.. I thought of a software that could check periodically and do update when it's needed like the automatic Windows Updates..

I would be thankful for any information or resource..

the question is solved.. Don't know why I didn't check the X CTU documentation.. It's written there, that there is automatic updates.
