AT Commands successful, but command values reset to previous when Xbee unplugged

XBee & XBee Gateway XBee - 802.15.4

For days I thought my AT commands were failing because when I would plug the Xbee into XCTU, the values would not show as changed.

I monitored frames in and out of my arduino and confirmed that everything was being sent and received exactly as it is in XCTU. Then I added an LED to the DIO pin I was controlling and verified that the pin was indeed changing.

So if the arduino is accomplishing the same thing as XCTU, why is the new value not stored on the Xbee?

If you want a value to remain after a power cycle, you must issue the Write command.
