Changelog

Version 3.4.12026-08-19T16:07:12.804

A menu, instead of cycling through modes — the Diagnostics menu, the universal control contract, and the fact that holding BACK now exits from anywhere. Worth calling out because v2.0.1's notes had told users hold-to-exit wasn't possible on Pebble and put Exit in the menu as a workaround; v3 does it, so the notes explicitly retire that.
Ten new tests — Compass, Heart Rate, Health, Haptics, Touch Haptics, Piano, Bluetooth, Battery, Display, Device Info. Exactly ten: 5 original + 10 = the 15-test emery roster.
The original five, reworked — including one thing users will otherwise experience as a regression: Backlight RGB is gone on Pebble Round 2, since it has no RGB backlight LED. v2.0.3 did ship that test on gabbro (its notes mention resizing the round color picker), so it disappears on upgrade. I stated it plainly with the reason, rather than letting it read as a bug.
Tests that say why they can't work — the charger/Health-switch/off-wrist cases, and Battery's missing mAh.
Fixes in this release — the v3.4.1 compass freeze, described by symptom and cause without the firmware internals.

Touch Test — Watch Hardware Diagnostic

Test your Pebble's touchscreen, buttons, motion sensor, and RGB backlight in one
fast, no-fuss app.

Five diagnostics:

• Touch — tap anywhere and a red marker drops exactly where the watch registered
  your touch, with the raw x, y coordinate over a reference grid and crosshairs.
  The quickest way to check whether your touchscreen is aligned.

• Zones — sweep your finger across the whole screen; each zone turns green until
  every one has registered ("ALL ZONES OK"), so you can find dead spots. Hold
  SELECT to reset and run it again.

• Buttons — press and hold BACK, UP, SELECT, or DOWN and watch the matching
  on-screen button light up, with an animation from that button's edge of the
  screen. Holding shows a sustained "held" state.

• Motion — a live tilt bubble-level, per-axis X / Y / Z readouts, and a "SHAKE!"
  flash, driven by the accelerometer.

• Backlight — a color wheel; touch it to tint the RGB backlight LED to any color,
  with a live hex readout. Hold SELECT to reset the light to white.

Getting around: UP / DOWN switch diagnostics with a smooth Pebble-style slide;
SELECT opens a menu to jump straight to any test (or Exit). Lightweight and
event-driven — nothing runs in the background, so it won't drain your battery.

Built for Pebble Time 2 (emery) and Pebble Round 2 (gabbro) — the Pebble models
with a touchscreen and color backlight.
