This adds the frame information while decoding:
> HCI Event: Number of Completed Packets (0x13) plen 5
Num handles: 1
Handle: 256 Address: XX:XX:XX:XX:XX:XX
Count: 1
#188: len 850 (755 Kb/s)
Latency: 9 msec (3-21 msec ~6 msec)
Channel: 68 [PSM 25 mode Basic (0x00)] {chan 4}
Channel Latency: 9 msec (7-21 msec ~9 msec)
Or the speed estimation while analyzing:
