- Screen PIN (Settings > Display & power > Security): 4-8 digits in NVS, keypad on the lock card after every wake and on boot, 5 misses -> 30 s pause - Live map tiles: missing tiles at the current zoom are fetched over the saved WiFi, written to the card and drawn; WiFi drops 30 s after leaving the map; "Live tiles" switch in Map tools - Firmware update (Settings > System): checks the fork's latest release, streams the -ota.bin into the spare app slot over TLS verified with the Arduino 3.x CA bundle, checks image magic/chip id, restarts - Release workflow publishes *_solo_lvgl envs (merged image + -ota.bin) Co-Authored-By: Claude Opus 5.5 <noreply@anthropic.com>

# 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
|
||
|
||
- [x] Keyboard: a key that closes it (so far a message could only be sent).
|
||
- [x] "+" placeholders at every field that sends text (compose, quick
|
||
messages, bot replies).
|
||
- [x] Short, terse descriptions on buttons and rows.
|
||
- [x] WiFi off switch.
|
||
- [x] Buttons as decided above.
|
||
|
||
## 2. Arduino-ESP32 3.x, PSRAM
|
||
|
||
- [x] 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.
|
||
- [x] Port: speaker (new I2S driver), BLE (NimBLE), ESP-NOW (IDF 5 callbacks);
|
||
HTTPS map download and LovyanGFX build unchanged (check on the device).
|
||
- [x] 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.
|
||
|
||
- [x] 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.
|
||
- [x] Settings in L1's order: display, sound, radio (with Bluetooth, WiFi),
|
||
system, keyboard, contacts & messages.
|
||
- [x] 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
|
||
|
||
- [x] Screen-lock PIN: 4-8 digits in NVS (`lvport::loadPin`), asked on
|
||
every wake and after a reboot, 5 misses pause entry for 30 s;
|
||
Settings > Display & power > SECURITY.
|
||
- [x] Map tiles fetched live while online: the map queues tiles it is
|
||
missing, `TileDownloader` fetches them one at a time over WiFi (connected
|
||
on the first miss, dropped 30 s after leaving the map) and saves them to
|
||
the card; Map > ☰ > Live tiles (NVS, on by default).
|
||
- [x] One-button OTA from GitHub Releases: Settings > System > Firmware
|
||
update (`OtaScreen.h`). The latest release's `-Wio-Tracker-L2-ota.bin`
|
||
(app image; `build-solo-firmwares.yml` now publishes `*_solo_lvgl`) is
|
||
streamed over TLS verified with the framework's CA bundle into the idle
|
||
slot of `default_16MB.csv` (two 6.25 MB app slots, no layout change),
|
||
chip id checked, then restart. Arduino 3.x builds only.
|
||
- [ ] Before the first release with L2: make the 3.x env the
|
||
`*_solo_lvgl` one (stage 2's last item), then test an update end to end.
|
||
|
||
## 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).
|
||
|
||
## Backlog (found along the way)
|
||
|
||
- [ ] USB power detection: `WioTrackerL2Board::isExternalPowered()` reads
|
||
STATUS0 (0x40) bit 7 of the chip at I2C 0x22 and always gets 0 with
|
||
USB plugged in (0x40 reads 0x01). Needed for a charging indicator and
|
||
for skipping the low-battery shutdown on the cable. Find the right
|
||
chip / register (devices on the bus: 0x14, 0x18, 0x21, 0x22, 0x2c,
|
||
0x34, 0x48, 0x5d). Found 2026-09-26.
