changing the routing protocol

Hi I am doing some research in routing protocols. I need to change the routing protocol for the XBee Pro 802.15.4 modules andtest some protocols . How can I do this?

Thanks in advance.

You should contact Digi tech support. However, you will need to fully replace the firmware. Digi won’t give you source code to fiddle with.

So if the use an Xbee with an Ember chip, you can of course load any other third-party Ember code on it.

This will not be an easy project.

The alternative is to use the S1/802.15.4 Xbee which do NOT routing. They are direct peer-to-peer or broadcast. Then write your own code on a second processor to route as you desire.
