Squash merge of feat/location-beacon-alerts-autopause (v1.21).
Features:
- Live Location Sharing — broadcast position as movement-gated [LOC]
messages to a channel or contact; live shares show as map pins with
distance/bearing in Nearby Nodes and a status-bar indicator. [LOC] is
parsed in DMs, channel messages and room messages; DM shares name the
sender.
- Locator (geofence) — arm a geofence around a saved waypoint or a person
(live [LOC] or last-known position), alert on arrive/leave or near/far,
with an optional homing beeper (gated to arrive/both modes). Arm from
Tools > Locator, Nearby Nodes, or Waypoints; target picker lists
favourites first, clearable via a "None" entry. Active target is drawn
as a flag on the map.
- One active target shared across Locator / Navigate / Map via a single
resolver (resolvePersonPos / activeTargetPos) that prefers a live
[LOC] share over the last-advertised GPS fix.
- Follow live contacts — Navigate to a live-sharing contact follows them
as they move and adds an ETA line; quick-share your own position from
the Map.
- Map & status-bar upgrades — home mini-map gets a north marker, scale
tick, and a connected trail line (was disconnected dots); status line
shows tracked-node count, an arrow + distance to the active Locator/Nav
target (falling back to the nearest live-tracked contact); GPS fix icon
in the top status bar, shown only on GPS boards with GPS enabled.
- Trail auto-pause — recording freezes on stops (banking elapsed time,
breaking the map line across the idle gap) and resumes on movement
without ending the session.
- Streaming trail simplification — GPS points are simplified in-stream
via a fixed-corridor (Reumann-Witkam) pass tuned for fidelity: straight
runs collapse to their endpoints, curves stay bounded to the Min-dist
tolerance, so the 512-point buffer covers a far longer route than a
flat point budget would suggest.
- Collapsible Tools (Location / Comms / System sections, fold-in-place
like Settings) and page-indicator icons on the home carousel.
- Waypoint coordinate editor — add a waypoint by scroll-editing lat/lon
digit by digit.
Fixes:
- Critical: low-heap hang and contact loss on RAM-tight builds. Halved
message-history scrollback rings (recovering ~14 KB free heap) and
made contacts/channels/prefs persistence atomic (temp file + rename),
so an interrupted save can no longer corrupt or wipe the store.
- Serial.write() bounded so a stalled USB host can't hang the device.
- Nearby Nodes: live [LOC] senders respect the type filter, sort by
shared position, and the list refreshes so live shares bubble up.
- Map: live contacts are labelled before waypoints.
- GPS status icon hidden when GPS is off in Settings.
- Splash screen no longer truncates a pre-release tag's own dash (e.g.
v1.21-rc1) when stripping the build's commit-hash suffix.
- Null-guarded the Locator target picker; clamped loc-share channel
index on load.
Under the hood:
- -Os size optimisation on the e-ink and GAT562 30S solo envs.

Settings > Radio gains a repeater toggle, 16 community-suggested radio
presets plus manual Freq/SF/BW/CR tuning (digit-by-digit Freq editor),
4 persisted user preset slots, and the packet pool bumped 16->32 so
queued retransmits stop starving incoming-packet allocation while
relaying.
Four opt-in politeness knobs (skip-advert, max-hops, yield, min-SNR),
all flood-only and off by default, plus overhear suppression that
cancels a queued retransmit if a peer relays the same packet first.
Adaptive Power Control is suppressed while relaying (pins TX power to
the ceiling) and duty-cycle RX is forced off, since a repeater needs
to hear and relay at consistent power.
A dedicated Tools > Repeater screen consolidates the toggle, the
politeness knobs, and live forwarding stats, plus an optional "Custom"
radio profile — a dedicated frequency/SF/BW/CR for relaying, separate
from the companion's own network, band-matched to the companion
frequency by default and used everywhere a radio change can happen
(boot, on-device toggle, app-driven CMD_SET_RADIO_PARAMS, Settings
radio edits) so the device never silently falls back to the wrong
params mid-relay.
Diagnostics gains the actually-forwarded packet count, real heap-free
via mallinfo(), a reset-counters popup, and hardened loop-detect
bounds. Also: a frequency-floor fix and a float-equality preset-match
fix in the repeater profile logic, deduped BW-table/valCol/profile-
seeding helpers shared between Settings and the Repeater screen, and
a build.sh fix tolerating control characters in `pio project config`'s
JSON dump.

Two independent, default-off toggles under Settings › Radio.
Pwr save: hardware RX duty-cycle (SX126x SetRxDutyCycle via
startReceiveDutyCycleAuto). The chip cycles RX↔sleep and wakes on a preamble —
no MCU state machine; recvRaw reads the packet exactly as in continuous RX.
Falls back to continuous RX on non-SX126x. (Replaces an earlier software-CAD
state machine that fought the hardware: polling a warm-sleeping chip gave a
phantom-busy channel that stalled TX ~4 s and dropped ACKs in the scan gaps.)
Auto pwr: Adaptive Power Control. tx_power_dbm becomes a ceiling; actual TX
power tracks the reverse-link SNR margin (measured above the per-SF demod floor,
EWMA-smoothed, proportional step with a deadband). Feedback comes from direct /
room-server ACKs and, for channels (no ACK), from hearing a repeater rebroadcast
our own flood; a lost confirmation ramps power back up so channel sends can't get
stranded below what the repeaters can hear.
Prefs schema 0xC0DE0009 (rx_powersave, tx_apc). Radio page / name bar show the
live TX power; noise floor reads n/a while duty-cycling.

Add a navigation tagline to the intro and a dedicated "GPS navigation"
feature-highlights block (waypoints, compass, navigate-to-anything,
location sharing, trail, global units); note location nav in the Messages
entry and expand the Tools entry to cover waypoints/compass/navigate.

README:
- Fix typo "offical" → "official"
- File names in Firmware Variants table now match workflow output
(solo-<version>-oled.uf2 / solo-<version>-eink.uf2)
- Un-comment the E-ink Display section (now fully supported)
- Clock Screen: "sensor values" → "data fields" (covers Batt%, Nodes, Msgs)
- Tools Screen: mention nearby nodes and auto-advert in the highlight
- Promote Screenshot Tool to its own top-level section (was buried under
Contributing); fix `uv run tools/screenshot.py` invocation path
Docs:
- favourites_dial: document the 3rd pin-picker tier (all chat contacts
fallback) added in 0e0e5b93
- clock_screen: Altitude source clarified — onboard sensor (GPS or
barometric), not always GPS
- message_screen: blank lines around image tables that were inlined
Code:
- UITask.cpp: rename leftover plus_y/plus_label locals to solo_y/solo_label
in the splash-screen Solo banner
Workflow:
- workflow_dispatch builds previously labelled firmware with the branch
name (GITHUB_REF_NAME). Resolve BUILD_VERSION to the tag when run on a
tag push, else dev-<short-sha> so manual runs produce
solo-dev-abc1234-oled.uf2 etc.
Cleanup:
- remove stray docs/solo_features/settings_screen/set_scr_1_eink copy.png
Co-Authored-By: Claude Opus 4.7 <noreply@anthropic.com>
- Adds the possibility to capture the device screen and save it as a PNG
image
- Wrap the code behind ENABLE_SCREENSHOT build flag, as per instructions
in README
Add an optional dot/intersection scale grid to the trail map view:
- renderGrid() draws labelled grid lines anchored to display edges
- Grid step auto-selected for ~3 intervals in the shorter dimension
- MIN_GRID_PX=22 prevents density on small/OLED screens; clamp ensures
minimum 2 intervals on large trails
- Intersections inside the label bbox and north-arrow bbox are suppressed
- Toggle via Hold-Enter action menu (Grid: ON/OFF item in ActionId enum)
- Map title shows 'TRAIL MAP+' when grid is active
- README updated to mention grid toggle

- Expand README: ringtone editor now documents two melody slots, full
note spec, and melody assignment to DM/channel notifications; settings
section lists DM Melody and Channel Melody options; context menu
description updated with melody override detail
- Rename quick reply template labels from M1-M10 to Q1-Q10 to avoid
ambiguity with melody slot identifiers M1/M2
- Increase DM message history buffer from 32 to 64 entries

This is a key difference compared to other systems and I see people
asking this a lot. It is mentioned in the FAQ but let's make it more
prominent in the README.
