Sniffing established BLE connections with HackRF One

Bluetooth Low Energy (BLE) powers hundreds of millions of IoT devices — trackers, medical sensors, smart home systems, and more. Understanding these communications is essential for security research and reverse engineering. In our latest article, we explore the specific challenges of sniffing a frequency-hopping BLE connection with a Software Defined Radio (SDR), the new possibilities this approach unlocks, and its practical limitations. 🛠️ What you’ll learn: Why SDRs (like the HackRF One) are valuable for BLE analysis The main hurdles of frequency hopping — and how to approach them What this means for security audits and proprietary protocol discovery ➡️ Read the full post on the blog submitted by /u/uBaze [link] [comments]Technical Information Security Content & DiscussionRead More
