4.4 Packet Error Rate Statistics
The
Packet Error Rate
(PER) Stats view provides a dynamic graphical representation of the Packet Error
Rate for each channel. The dialog displays a graph for each Classic
Bluetooth
channel numbered 0 through 78
and for each
Bluetooth
low energy channel numbered 0 through 39.
Packet Error Rate Stats
assist in detecting bad communication connections. When a high percentage of re-
transmits, and/or header/payload errors occur, careful analysis of the statistics indicate whether the two
devices under test are experiencing trouble communicating, or the packet sniffer is having difficulty listening.
Generally, if the statistics display either a large number of re-transmits with few errors or an equal number of
errors and re-transmits, then the two devices are not communicating clearly. However, if the statistics display
a large number of errors and a small number of re-transmits, then the packet sniffer is not receiving the
transmissions clearly.
