JakubandClaude Opus 5.5 b5e4845dae feat(ui-lvgl): quick panel from the status bar; L2 fixes from rc1
The quick panel, as a phone's: pulled down from the status bar (or a tap
on it). Bluetooth, WiFi, GPS, sound, trail and live share switch at a
tap; Advert opens the advert popup (moved here from the Nodes header);
Lock locks the screen; a brightness slider. Holding a tile opens its
settings. Lock and sun glyphs added to the fonts.

Fixes from rc1 testing on the L2:
- GPS status icon: none when GPS is off (the module kept its last fix
  valid, so it stayed green); grey on, green with a fix. ensureGps()
  turns GPS on before trusting that stale fix.
- Screen wake: the panel wakes dark, a frame is drawn, then the
  backlight fades in -- no white flash. Off fades out first.
- Power off / flat battery: the chip wakes every 30 s to look for USB
  power and starts when plugged in (it slept with no wake source before,
  until the reset button). Plugged in when switched off: stays off until
  re-plugged.
- Message ages in a conversation refresh every 2 s, as on ui-new; the
  message popup keeps its age, repeaters heard and delivery up to date.

MeshCore Solo

MeshCore Solo

Solo is a MeshCore companion firmware that works on its own: messages, contacts, GPS navigation and tools right on the device, no phone needed. The phone app still connects as with the stock firmware, over Bluetooth or USB.

Try it in your browser: solo.marekzegarek.com

What it does

  • Messages without a phone: channels, direct messages and rooms, with quick replies, live placeholders ({loc}, {time}, sensor readings) and keyboards for Latin, Cyrillic, Greek and European diacritics.
  • GPS navigation: trail recording with GPX export, waypoints, a compass, navigate to any node, waypoint or shared location, live location sharing and a geofence alert (Locator).
  • Nearby nodes: who's around, signal and distance, ping, and remote admin of your repeaters and rooms.
  • Tools: clock with alarm, timer and stopwatch, a remote bot that answers commands over the mesh, repeater mode, a ringtone editor, and a status screen with the radio, GPS, battery and mesh counters.
  • Screen lock with an optional PIN.
  • On the Wio Tracker L2: an offline map, message history on the SD card, the SD card as a USB drive, updates over WiFi.

Devices

The firmware is the same everywhere; how you drive it depends on the device. These docs mark the differences with notes like this:
