The data collector sends a many-to-one route
request broadcast to create reverse routes on
all devices.
Acquiring Source Routes
Storing Source Routes
Sending a Source Routed Transmission
Acquiring source routes requires the remote devices to send a unicast to a data collector (device that sends
many-to-one route request broadcasts). There are several ways to force remotes to send route record
transmissions.
1.
transmission will force a route record to occur.
2.
devices to send a network discovery response. Each network discovery response will be prefaced by a route
record.
3.
Each IO sample would be prefaced by a route record. (See chapter 8 for details.)
4. If the NI string of the remote device is known, the DN command can be issued with the NI string of the
remote in the payload. The remote device with a matching NI string would send a route record and a DN
response.
When a data collector receives a route record, it sends it out the UART as a Route Record Indicator API
frame (0xA1). To use source routing, the application should receive these frames and store the source
route information.
To send a source routed transmission, the application should send a Create Source Route API frame (0x21)
to the XBee to create a source route in its internal source route table. After sending the Create Source
Route API frame, the application can send data transmission or remote command request frames as needed
to the same destination, or any destination in the source route. Once data must be sent to a new
destination (a destination not included in the last source route), the application should first send a new
If the application on remote devices periodically sends data to the data collector, each
The data collector can issue a network discovery command (ND command) to force all XBee
Periodic IO sampling can be enabled on remotes to force them to send data at a regular rate.
A remote device sends
an RF data packet to
the data collector.

After obtaining a
source route, the
data collector sends
a source routed
transmission to the
remote device.
