BLE-Replay

BLE-Replay BLE-Replay is a Bluetooth Low Energy BLE peripheral assessment tool. It pulls/consumes Bluetooth HCI logs from your mobile device and extracts all of the writes that the central makes to a peripheral. This data can be replayed using most Bluetooth dongles from a Linux host, or saved to...
