Read an Xbee "Node Identifier"?

Using Arduino Networking, Protocols, and Devices
1

Series 2 (actually S3B) radio. I would like to read its NI and use it to update a value.

For example, I have an arduino and xbee doing its thing in the field. I would like to change its "number" remotely. I have it setup that when it sends data out, one of the payload bytes is the identifier of the Arduino. If I want to change its "number" I would like to just change the NI field using XCTU.

Thanks

Were you ever able to read the NI using the Arduino-Xbee code?
