# pocket-client: a BLE client for the Pocket voice recorder

> pocket-client implements the Pocket voice recorder's recovered BLE command protocol in a Swift library and CLI. It documents authentication, status and recording inventory exchanges, MP3 transfer and control commands, using findings from vendor-app HCI captures and live device probes.
