## What it is
Sniffle is an open-source sniffer for Bluetooth 5 and 4.x LE that runs on TI CC1352/CC26x2 hardware with a Python host-side tool. It captures BLE advertisements and connections, exports PCAP files, and includes a Wireshark plugin for analysis.

## Use cases
- sniff bluetooth low energy packets
- capture BLE advertisements from a specific device
- reverse engineer BLE device communication
- debug bluetooth 5 connections
- capture BLE traffic to pcap for wireshark analysis
- monitor BLE connection establishment reliably
- analyze bluetooth 5 extended advertising

## When to choose
- you need to sniff Bluetooth 5 or 4.x LE traffic with affordable TI Launchpad hardware
- you want reliable connection detection via all three advertising channels
- you need PCAP export and Wireshark integration for BLE analysis
- you want an extensible Python-based BLE sniffer

## When to avoid
- you need to sniff Bluetooth Classic (BR/EDR) traffic
- you don't have compatible TI CC1352/CC26x2 hardware
- you need a turnkey commercial sniffer with GUI support
