Note We made the data throughput measurements by setting the serial interface rate to 115200 b/s,
and measuring the time to send 100,000 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
n
Note The timeouts in this documentation are theoretical timeouts and are not precisely accurate.
Your application should pad the calculated maximum timeouts by a few hundred milliseconds. When
you use API operating mode, use
a transmission is complete.
Unicast one hop time
unicastOneHopTime is a building block of many of the following calculations. It represents the amount
of time it takes to send a unicast transmission between two adjacent nodes. The amount of time
