Bluetooth Timeline Average Payload Throughput
The figure depicts the Throughput display with
the Average Throughput indicators in the left column.
Average Throughput is the total payload over the entire
session divided by the total time. Total
time is calculated by taking the difference in timestamps between the
first and last packet. In Bluetooth,
timestamp difference is used instead of Bluetooth
clock count because timestamp difference is immune to role switches. However,
this can result in inaccuracies when the duration is small enough that
a coarse timestamp granularity is significant.
- Average Throughput is shown as 0 when there is only one packet, because in that case the timestamp difference is 0 and an average cannot be computed.
- Duration is the beginning of the first packet to the end of the last packet.
- Duration for average throughput is beginning of first packet to end of last packet. If a single packet is selected, the duration of that packet is used.
- Average Throughput is shown for all devices, master devices, and slave devices.
- A horizontal bar indicates
relative percentage. Text
displays the throughput value.
