JakubandClaude Opus 5.5 e154a4e721 feat(l2): Gallery app (screenshots as thumbnails, full view with swipe and delete, the saved trails), the clock from NTP while WiFi is up (the router's server from DHCP first), tabs switch on release, Home apps out of Settings
- Gallery: thumbnails 30 to a page, built only while the screen is still (a decode held the loop and a scroll read as a tap)
- segmented(): CLICK_TRIG, so a swipe starting on a screen's tabs doesn't switch them
- Settings > Device > Home apps removed (hold an app on Home instead)
- platformio.ini: a note that the L2 has no microphone on GPIO15 (verified on hardware)

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.

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:
