What is a LAST file?

LAST files mostly belong to Wireshark. LAST files are Bluetooth HCI snoop log files. They record the data exchanged between a computer and a Bluetooth adapter.
Such logs capture detailed HCI packets including commands, events, and data transmissions. They help in troubleshooting and analyzing Bluetooth communications.
These files are similar to the alternative description btsnoop_hci.log and are managed by Wireshark.

Purpose: To log the low-level Bluetooth activity.

Functionality: They capture and store HCI command and event data for later analysis.

Usage: Open them with Wireshark to inspect packet details.
