# Pocket Libre: reconstructing Pocket recorder transfer over BLE

> Pocket Libre reconstructs the Pocket AI recorder's BLE command and audio-transfer behavior in a Python client. Its protocol notes map APP commands, MCU responses, GATT characteristics and MP3 streaming from HCI captures; the client downloads recordings and offers local transcription and speaker identification.
