4.3.2.11 low energy Packet Discontinuities
The following figure depicts a discontinuity between two packets.
Figure 4.42 - Bluetooth® low energy Packet Discontinuity
To keep the timeline and the throughput graph manageable, big jumps in the timestamp are not represented
linearly. Instead, they are shown as discontinuities. A discontinuity exists between a pair of packets when the
timestamp delta (the timestamp of the second packet minus the timestamp of the first packet) is (1) more than
4.01 seconds or (2) is negative. The reason that the discontinuity trigger is set at 4.01 seconds is because the
maximum connection interval time is 4 seconds.
