Change MAC address of XBEE PRO S5?

XBee & XBee Gateway

Hi,
lets assume we have network of PRO S5 868 modules.
There is one central node and 50 sensors.
Each sensor has hardcoded address of central node (if will send to broadcast there will be no confirmation).
In situation when central node stops working (e.g. hardware issue) need to reprogram those all 50 sensors to new address of central node replacement.

  1. Is it possible to change MAC address of a module?
  2. Is possible to order e.g. 3 modules with the same MAC address?
  3. Maybe we do this in bad way and there is a better?

Thanks!

No, you are not able to replace or re[program the MAC address as that is an IEEE assigned address. You probably will want to use the ND, NI, and DN commands to replace the module with.
