# KardiaMobile 6L Unlocked: a direct BLE ECG client

> KardiaMobile 6L Unlocked reconstructs the BLE exchange used to obtain ECG samples from the AliveCor KardiaMobile 6L. Android HCI captures inform the bonding sequence, derived unlock token, and two-channel sample framing; a Python client records the stream on Linux and writes CSV, PNG, and PDF outputs.
