Mobile LA518 Recorder

NativePHP Mobile plugin for LA518-based BLE voice recorders (Umevo Note Plus and OEM rebadges). Connect, list recordings, start/stop recording, download MP3s, and consume live audio and VU level data — all from PHP and JavaScript.

The full BLE protocol was reverse-engineered from PacketLogger captures of the official iOS app. See PROTOCOL.md for the complete wire-level spec.
