## What it is
BtleJack is a Python CLI tool for sniffing, jamming, and hijacking Bluetooth Low Energy (BLE) connections. It relies on BBC Micro:Bit, Bluefruit LE, or nRF51822-based hardware running dedicated firmware, and supports BLE 4.x and limited BLE 5.x.

## Use cases
- sniff an existing BLE connection
- capture new BLE connection requests
- jam a Bluetooth Low Energy connection
- hijack an active BLE connection
- export captured BLE packets to PCAP
- audit BLE device security with cheap micro:bit hardware

## When to choose
- you need a low-cost BLE security testing toolkit using Micro:Bit or nRF51822 hardware
- you want to sniff, jam, or hijack BLE 4.x connections from a UNIX system
- you need PCAP export of captured BLE traffic for further analysis

## When to avoid
- you need full BLE 5.x support such as coded PHY or channel map updates
- you are on Windows, since only POSIX-compatible systems are supported
- you have no compatible radio hardware (Micro:Bit, Bluefruit LE, or nRF51822 board)
