- BLE (ESP32): fast advertising (20-30 ms) for 30 s, then 152.5 ms, as the
nRF52 interface; the library default kept 30-60 ms forever
- Live map tiles: the WiFi drops after a minute with nothing missing
- ES8311 to standby while the I2S clocks are off, set up again before the
amp comes on
- Buzzer: no channel (DMA out of memory) waits out the samples instead of
spinning above the UI loop
- OTA: the image header check waits for its 16 bytes
- Comments: P10 is just the LED; the LCD SPI clock is 40 MHz on the wire

The LoRa noise floor with the board's parts off one at a time, sweeps of
850-930 MHz, the mesh channel and a 7.8 kHz zoom on its loudest point; a
slow cycle of the same states for a second radio beside the device; and
a spike hunt over 864-876 MHz listing the lines over the floor and their
spacing (how the I2S MCLK comb was found).

The speaker's I2S channel was only disabled when idle, which leaves MCLK
running. Its fractional divider (160 MHz / 39 1/16 = 4.096 MHz) makes a
comb of lines every 256 kHz: one at 869.632 MHz, in the EU narrow mesh
channel, lifted the LoRa noise floor from ~-102 to ~-85 dBm, and others
land near GPS L1 and BeiDou B1. The channel is now deleted and its pins
held low after each sound, and made again for the next one. Measured:
noise floor -102 dBm, outdoor first fix 87 s (was 620 s and more).
Also: TCXO at 3.0 V (the L2's part, as Meshtastic has it); GLONASS
enabled on the L76K after each power-up; begin() on a running receiver
no longer resets it (a reset threw away the acquisition in progress).

Power: the UI loop sleeps until something is due (never with packets
queued); screen off puts the CPU at 80 MHz, the GT911 to sleep (unless a
tap wakes the screen) and the LP5814 in standby. GPS off now cuts the
L76K's rail and UART on the L2 (L2GpsProvider). The battery divider is
powered only for a reading (measured: settles at once); readings within
2 s are reused. The SD mount is retried at most every 5 s.
Fixes: WiFi left on after leaving a scan, live tiles' WiFi kept with the
screen off on the map, an ADC read every second for the status bar, touch
polled on every pass while dark, a scan cutting an update's WiFi, relay
count not refreshing in a channel thread, raw @[nick] in room previews.
Labels skip unchanged text (no redraw).
Helpers: scrollList, dimOverlay, settingRow, flexBox, nvs::get/put,
trailFilePath (a second save in the same minute no longer overwrites),
unreadTotal. Dead code removed.

- The AW35615 USB-C controller (FUSB302-style registers, ID 0x91) only
reports VBUSOK with its measure block on; POWER resets to bandgap only,
so isExternalPowered() was always false. Board init turns it on
- Status bar shows a charge bolt on the cable, Diagnostics > Live has a
Power row, the GPS screen notes that charging disturbs GPS, and the
low-battery warning is skipped on USB as intended
- Roadmap: USB detection closed; GPS indoors still worse than the L1
even on battery, left open for later

- Message history archived per conversation on the SD card (HIST_ARCHIVE):
restored on boot, Older/Newer paging in threads, kept count selectable
- Settings > System > Storage: card and flash usage, breakdown by maps,
messages, trails and other, kept-per-chat setting, delete history;
reads the mounted volume and warns when the FAT partition is much
smaller than the card
- Saved trails on the card: every Save is a new file, Load opens a list
with load (framed on the map), GPX export and delete
- Diagnostics: GPS data rows, last start reason, last crash summary
- Messages restored before the clock is set show their date instead of 0s

A failed ADS1115 read returned 0 mV, so the status bar showed 0 % (and the
low-battery shutdown could see an empty battery) until a reboot. Retry once,
then keep the last good value.

- genericBuzzer I2S path (BUZZER_I2S): an audio task synthesises the notes
with eased edges and keeps the DMA queue fed with silence between sounds;
ES8311 setup; amp powered through the board only around sounds
- ui-core/SoundControl.h (mode, volume, built-in sounds, melody model),
SoundNotifier moved to the Core, chanctl::melody, schema Sound page
- L2: notifications, alarm / timer ring, locator sounds, Settings > Sound,
melody editor with the playing note lit, per-chat sound, mute icon
- noteIndex() on every buzzer backend; scrolling popups past screen height

Seeed Wio Tracker L2 (ESP32-S3R8 16MB/8MB PSRAM, SX1262, NV3031B 320x240
QSPI LCD + GT911 touch + LP5814 backlight, TCA9535 expander gating every
rail, ADS1115 battery ADC, AW35615 USB-C, L76K GNSS).
Board layer ported from meshcore-dev/MeshCore PR #3381 (Hacuchino-hash),
kept at the same paths for an easy upstream merge. Differences:
- display: dropped the UIColor theme (not adopted in this fork)
- GpsTap diagnostics wrapper omitted; GNSS reads Serial1 directly
- nv3031b ODR fix dropped: LovyanGFX >= 1.2.30 (now pinned) defines
Panel_NV3031B::init_cmds itself -- the fix became a duplicate symbol
- MESH_DEBUG_PRINTLN with a non-literal format fixed (broke MESH_DEBUG builds)
- upload_speed 115200: baud is virtual on native USB; skips the switch
solo/wio-tracker-l2 adds Wio_Tracker_L2_companion_solo_bringup: ui-new
zoomed 2x, BOOT button only, no touch -- a hardware smoke test, not a
release target (deliberately not *_solo_dual, so CI doesn't publish it).
The real UI for this board will be a new LVGL frontend.
Verified on hardware: boot, display, radio, GPS, battery, BLE app link.
First boot takes tens of seconds while SPIFFS formats its 3.4 MB partition.
