Sniffle: A low-cost sniffer for Bluetooth 5
summary
Open source firmware and Python host tools turn a $40 TI development board into a Bluetooth 5 LE sniffer that supports 2 Mbps and long‑range PHYs, extended advertising, channel map and hop updates, and CC26x2/CC13x2 radios. It records traffic to PCAP files, exposes a simple Python API, and uniquely captures advertisements on all three primary advertising channels with a single device, yielding over 90% reliability for connection detection in quiet RF conditions.
