Settings > Display > Theme: Dark / Light (NVS mc_ui/light). The colour tokens are set once before anything is built, so a change restarts the device. Text on an accent fill is the new ON_ACCENT (it was BG, white in the light theme); each accent has a deeper hand-picked light variant that reads on white and takes white text. The map's empty-tile fill and grid and the areas' outlines follow the theme too. Co-Authored-By: Claude Opus 5.5 <noreply@anthropic.com>
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:
