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:

  Found BR-ACL connection with handle 256
        Address: XX:XX:XX:XX:XX:XX
        60 RX packets
        22548 TX packets
        22547 TX completed packets
        3-73 msec (~11 msec) TX Latency
        6-850 octets (~847 octets) TX packet size
        ~568 Kb/s TX transfer speed
