JakubandClaude Opus 5.5 087bac89b4 feat(ui-lvgl): roadmap stage 4 - tools grouped by context, Settings in L1 order, full status icons
- Map tools hold trail, live share and arrival alert, with their options
  (schema page "Map options") behind one button; back returns to the map
- Nearby gets an advert button: send now (nearby / everyone) + auto-advert
- Home page 3: Repeater, Admin (list of repeaters and room servers),
  Diagnostics
- Settings: display, sound, radio (Bluetooth, WiFi), system, keyboard,
  contacts & messages; units moved to Display & power
- Status bar: Bluetooth, GPS, alarm, mute, then auto-advert, trail, live
  share, repeater, arrival alert in the accent colour
- Fonts: key and route glyphs

Wio Tracker L2 (ui-lvgl) roadmap

The L1 → L2 feature port and its audit are done (2026-09-26). This is the plan for what comes next, in order. Tick items off as they land.

Decisions already made:

  • Buttons: WAKE (side, expander P00) turns the screen off / on. USER/BOOT goes back; holding it mutes / unmutes the device.
  • Placeholders: the "+" popup next to a text field is the placeholder UI; it must offer every placeholder and appear at every field that sends text.
  • Message history: kept on the SD card, about 100 per conversation to start with.
  • OTA: firmware comes from this fork's GitHub Releases.
  • PIN: screen lock only, for now.

1. Quick fixes

  • Keyboard: a key that closes it (so far a message could only be sent).
  • "+" placeholders at every field that sends text (compose, quick messages, bot replies).
  • Short, terse descriptions on buttons and rows.
  • WiFi off switch.
  • Buttons as decided above.

2. Arduino-ESP32 3.x, PSRAM

  • A separate L2 env on pioarduino 55.03.312-1 (Arduino-ESP32 3.3.12, IDF 5.5): Wio_Tracker_L2_companion_solo_lvgl_v3; the 2.0.17 env stays until the new one passes the hardware checklist.
  • Port: speaker (new I2S driver), BLE (NimBLE), ESP-NOW (IDF 5 callbacks); HTTPS map download and LovyanGFX build unchanged (check on the device).
  • Large buffers in PSRAM (psramBuf): trail drawing, tile cache, map marks, list rows, keyboard maps, message metadata. Internal heap free at runtime: 2.0.17 147.8 KB; 3.x 128.2 KB before, 147.9 KB after (static RAM 109 → 71 KB). Measured with -D UI_HEAP_REPORT. History and a larger trail come to PSRAM with stage 3.
  • Full hardware checklist, then make the new env the default.

3. Data on the SD card

Postponed (2026-09-26): the user may extend this stage first.

  • Message history on SD, kept across reboots (~100 per conversation; the newest ones cached in PSRAM).
  • Trail sized to the device: thousands of points in PSRAM (now 512), saved to SD.

4. UI layout

L1 splits its tools into many small screens because of the joystick and the 128x64 display; the L2 groups them where they are used instead.

  • Tools: trail, live share and arrival alert stay in the map (its tools popup, with their options behind "Options"); the advert (send now, auto-advert) is in Nearby; Repeater, Admin (a list of repeaters and room servers) and Diagnostics are Home tiles next to Favourites, Compass, Clock and Bot. The melody editor stays in Sound.
  • Settings in L1's order: display, sound, radio (with Bluetooth, WiFi), system, keyboard, contacts & messages.
  • Every status icon L1 has (Bluetooth, GPS, alarm, mute, auto-advert, trail, live share, repeater) plus arrival alert; background modes in the accent colour instead of L1's blinking.

5. Security and internet

  • Screen-lock PIN.
  • Map tiles fetched live while online.
  • One-button OTA from GitHub Releases (release asset + partition layout check).

6. Theme

  • Develop the current look into a consistent, recognisable style (colours, corners, type, icons, states), after the layout of stage 4.

7. Research: LVGL for the other displays

  • Find out whether LVGL on every display variant gives consistency and a nicer look more easily. Adopt only if the result is better and every feature is kept (L1: 128×64 OLED, nRF52, RAM already 68% used).
