CE (Node Messaging Options)
This command applies to the XBee SX 868 RF Module.
The routing and messaging mode bit field of the device.
A routing device repeats broadcasts. Indirect Messaging Coordinators do not transmit point-to-
multipoint unicasts until an end device requests them. Setting a device as an end device causes it to
regularly send polls to its Indirect Messaging Coordinator. Nodes can also be configured to route, or
not route, multi-hop packets.

0
When encryption is enabled, AES Counter mode is used with a
256-bit key.
1
When encryption is enabled AES ECB mode is used with a 128-bit
key. This bit must be set when using encryption with versions of
the firmware prior to 9009. It may be used in all circumstances if
set consistently throughout the network, but it disables the more
secure counter mode encryption.
All other bits should be 0 for future compatibility.
