What's New in beacons
2.2.3
November 1, 2026
Ready for beacon firmware 2.2.3. When the update shows up in the Beacon tab, your beacon plays its startup and shutdown sounds in every alert mode, including vibrate, silent and Desert mode, so you can always hear it turn on and off. On the battery model, the beep when you hold the button to start also plays. A new Power sounds switch under Alerts turns those sounds off. It appears once your beacon runs firmware 2.2.3. With Power sounds off, the start beep becomes an LED flash. A beacon slim on USB power, for example in a car, now plays the startup sound each time its power comes on. Turn Power sounds off to keep it quiet. The vibrate and silent descriptions and the Desert mode note now say which sounds stay on. Help answers updated to match. Nothing is uploaded automatically, as always.
