MeshCore Solo Companion Firmware v1.22

What's new

• T9 on-screen keyboard — a new keyboard option under Settings › Keyboard. Alongside the existing alphabetical ABC grid, pick T9 for phone-keypad-style entry: each key is labelled with its digit and a letter group (e.g. 2abc), and repeated Enter presses cycle through the letters and then the digit. (The alphabetical grid was previously mislabelled QWERTY in Settings — it's always been a-b-c order and is now correctly named ABC.)
• Auto-save GPS trail on shutdown — a new Tools › Trail › Settings › Auto-save toggle (default off). With it on, the live trail is written to flash automatically at power-off, so a low-battery auto-shutdown no longer loses the whole route. It only writes when the trail actually has points, so an empty trail can't overwrite a previously saved one. Saves to the same /trail file as the manual Trail › Save.
• Clock Tools from the Tools menu — the Alarm / Timer / Stopwatch screen (reachable by pressing Enter on the Clock home page) now also has its own entry under Tools › System, so it's discoverable without first finding it on the clock face.
• Map & Shutdown pages are reorderable — the Map home page shipped with no entry under Settings › Home Pages, so it was always shown and couldn't be moved. It's now a first-class page there: toggle its visibility and reorder it like any other (visible by default; existing users keep it on). Reordering also now covers the Shutdown page, which was previously pinned to the end of the carousel.

Fixes

• Battery reads high and jittery on Wio Tracker L1 — a power-saving change had switched the battery-voltage divider on for only ~10 ms before each reading, too short for the high-impedance divider node to settle, so a full LiPo could report 4.6–5.0 V. The divider is now held on continuously again (a negligible ~2 µA on the 2×1 MΩ divider), giving stable, accurate readings. The CPU-sleep and LED energy savings from the same optimisation pass are untouched.
• Home page visibility no longer resets on update — the prefs schema-migration that turned the Favourites page on ran on every firmware update (any schema-version bump), so a page you'd deliberately hidden kept coming back after each release. It's now gated to the single upgrade that introduced Favourites, so your hidden pages stay hidden.
• a locked device didn't show the alarm — it woke the display, then immediately re-blanked, so a ringing alarm played to a dark screen. The lock screen now draws the alert and holds the wake for the whole ring.
• background-mode status icons vanished when Bluetooth was off — the auto-advert / live-share / trail / repeater indicators were nested inside the "BT on" check and are now always shown while their mode is active.
• a long alert message ("GPS on, tracking started") spilled past its box on a narrow screen — it now wraps to up to three lines and the box grows to fit.
• a contact name pushed from the phone app wasn't guaranteed to be NUL-terminated.
• the timer / alarm could mis-fire for a deadline landing past the ~49-day millis() rollover.
• toggling a channel's favourite from its context menu could retarget the menu onto a different channel once the list re-sorted.
• A repeater could appear twice on the discovery scan and in the app — a discover response often arrives more than once (the direct copy plus a re-flooded copy carry different packet hashes, so the mesh's duplicate filter passes both), and each copy was listed. Duplicate copies of the same response are now dropped for a few seconds after the first.
• Favourites self-heal — a pinned favourite whose contact no longer exists (e.g. after clearing contacts) now reverts to an empty + tile instead of showing (gone), and the stale pin is cleared from prefs.
• Radio preset names no longer seed {loc}/{time} placeholders — those only make sense in a message; the preset-name keyboard (Settings › Radio and Tools › Repeater "+ Save current…") now opens empty. The message-slot editor still keeps them. The room-login password keyboard drops them too.
• Room chat opens automatically after a successful login — logging in to a room server (first-time or a remembered password) used to drop you back on the room list, needing a second Enter to actually open the chat. The chat now opens on its own once the login succeeds, as long as you're still on that room in the picker.

Under the hood

• OLED draws less — the SH1106 driver now skips pushing a frame over I²C when it's byte-identical to the last one, cutting redundant traffic and a little power on the static screens (clock, home) that don't change between updates.
