About LAST files
A .LAST file is primarily a previous Bluetooth Host Controller Interface (HCI) Snoop Log generated by the Android operating system. When developers or users enable Bluetooth logging, Android records network packet data to a file (often btsnoop_hci.log). Upon reboot or toggling Bluetooth, this file is backed up with the .LAST extension. You can open and analyze these network captures using Wireshark.
The main disadvantage of the .LAST format is its arbitrary file extension. Operating systems like Windows and macOS do not recognize it, and double-clicking the file usually results in an error. Furthermore, the file is rarely plain text; it is typically encoded in a binary btsnoop packet format. Standard text editors will only display scrambled, unreadable characters. Because it acts as a system backup suffix rather than a registered standard format, standard online converters fail to process it.
To share or analyze the data properly, the best conversion targets are standard network capture formats like PCAP or PCAPNG, or plain text TXT for basic reading. This file format is difficult to open or convert without specialized debugging software since only protocol analyzers can parse the binary packet headers. Just drag and drop your file to convert.guru to identify the format, view the internal hex data, and convert it if the underlying embedded btsnoop format is supported.
Convert.Guru analyzes your LAST file, detects the exact format, and lets you read the text inside.
Users also converted LASTMEMORY, SNOOP, PCAP and CAP files.

The LAST Converter Story
The history of Convert.Guru began over 25 years ago in California with Tom Simondi’s file-format database. A former contributor to Space Shuttle development and a software pioneer of the 1980s, Simondi established a trusted resource for file type analysis that was even referenced by Microsoft Windows XP. Today, we use modern technology to process and convert thousands of file formats while continually improving our LAST converter.
