Module melodies 

Pre-baked melodies for the standard firmware events.

Statics

BEACON_ACK

Short confirmation blip after a beacon is transmitted.

DO_SILENCE

Short low blip played just before the buzzer goes silent.

GNSS_OFF

Receiver switched off: the held note first, falling away into two low pips — GNSS_ON in reverse.

GNSS_ON

Receiver switched on: two pips at one pitch, then a higher held note — “searching, and now looking”.

LOCATE

Locate alert: a two-tone warble, deliberately unlike any notification the device makes in normal operation, so it reads as “come find me” rather than “you have mail”. Played on repeat by BuzzerEngine::play_alert, which supplies the gap between passes.

POWER_OFF

Falling chirp: 2000 → 1500 → 1000 Hz.

POWER_ON

Rising chirp: 1000 → 1500 → 2000 Hz.

UNSILENCE

Bright blip played when the buzzer is un-silenced.
