RF Clown v2

RF-Clown – Portable BLE/Bluetooth Jammer (Educational Open-Source Device)

RF-Clown is a compact, portable open-source device for jamming Bluetooth Low Energy (BLE) and Classic Bluetooth signals. Intended strictly for educational and research purposes – it demonstrates wireless communication vulnerabilities. The tool transmits constant carrier interference on selected channels, effectively disrupting connections of BLE devices (headphones, watches, trackers etc.) and Classic Bluetooth. Single-button mode switching, mode indicated by RGB LED. Fully open-source – schematics, PCB and firmware freely available on GitHub.
