Transmission Timeouts - Digi XBee SX 868 User Manual

Networking methods
The following table shows the results of this test with various configurations. All measurements were
acquired by streaming 10,000 bytes of data in Transparent mode from the transmitter to the receiver
at a baud rate of 115,200 b/s.
Configuration
Point to Point, encryption disabled
Point to Point, encryption enabled
Mesh unicast, one hop, encryption disabled
Mesh unicast, one hop, encryption enabled
Mesh unicast, three hops, encryption disabled
Mesh unicast, three hops, encryption enabled
The following table shows the latency (in ms) for 10000 Bytes at 115200 b/s serial data rate.
Configuration
Point to Point, encryption disabled
Point to Point, encryption enabled
Mesh, encryption disabled
Mesh, encryption enabled
Note We made the data throughput measurements by setting the serial interface rate to 115200 b/s,
and measuring the time taken to send 10000 bytes from source to destination. During the test, no
route discoveries or failures occurred.

Transmission timeouts

When a device in API operating mode receives a Transmit Request (0x10, 0x11) frame, or a device in
Transparent operating mode meets the packetization requirements (RO, RB), the time required to
route the data to its destination depends on:
A number of configured parameters.
n
Whether the transmission is a unicast or a broadcast.
n
If the route to the destination address is known.
n
Timeouts or timing information is provided for the following transmission types:
Broadcast transmission
n
Unicast transmission on a known route
n
Unicast transmission on an unknown route
n
Unicast transmission on a broken route
