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)
