Transmission, addressing, and routing RF packet routing
XBee/XBee-PRO® S2C ZigBee® RF Module

route record transmission is unicast along the many-to-one route until it reaches the data collector.
As the route record traverses the many-to-one route, it appends the 16-bit address of each device in
the route into the RF payload. When the route record reaches the data collector, it contains the
address of the sender, and the 16-bit address of each hop in the route. The data collector can store
the routing information and retrieve it later to send a source routed packet to the remote as shown in
the following images.
The data collector sends a many-to-one route request broadcast to create reverse routes on all
devices.
A remote device sends an RF data packet to the data collector. This is prefaced by a route record
transmission to the data collector.
