Address the open items from the FEATURES.md audit backlog:
- saveChannels() now skips unused slots (all-zero secret) instead of
writing all 40 every time, so /channels2 holds only configured channels
(was always ~2.7 KB) and wears the flash less. loadChannels() already
compacted empties on read, so the loaded result is unchanged.
- findChannelIdx() returns -1 for an all-zero secret, so a corrupted/empty
channel can't match an unused all-zero slot and misroute messages.
- TrailStore gains a static_assert that CAPACITY fits the uint16_t save
header count, failing the build instead of silently truncating.
Also re-classify two audit items verified to be non-issues in current
code: the bot strstr "199-char" truncation (BOT_SCRATCH=200 >= MAX_TEXT_LEN
=160, unreachable) and the MSG_PICK reply title (rlen clamped to 20, so
title[24] never overflows).
Verified: WioTrackerL1_companion_solo_dual builds clean.

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.

Shows packet counts by category (RX/TX), radio noise floor/RSSI/SNR,
packet-pool free count and outbound queue length, uptime, and heap/stack
headroom on a single scrollable screen.
Adds generic per-payload-type RX/TX counters to Dispatcher (mesh layer),
plus pool-free/queue-length getters, and a new DeviceDiag helper for
nRF52 heap (linker-symbol + sbrk) and stack (FreeRTOS high-water-mark)
stats — the only platform needed for the 3 in-scope boards (Wio Tracker
L1 OLED/Eink, GAT562 30S), all nRF52840.

Content drawn under the title separator touched the line on every standard
screen, because listStart() == headerH() (the row right after the separator).
Graphical screens worked around it with a hand-rolled hdr+2.
Bake a 2px breathing gap into listStart() so every list gains it at once, and
switch the screens that hand-rolled the offset (Compass, Nav, Nearby detail) to
listStart() so the content top is computed the same way everywhere.

Fixes from a full ui-new audit (OLED + e-ink both build green):
- remove dead DisplayDriver::drawScrollArrows (all lists use drawScrollIndicator)
- SettingsScreen selection bar -> lineStep()-1, matching the drawList screens
- HomeScreen: don't force the 1s blink refresh on the CLOCK page (status icons
are hidden there anyway)
- FullscreenMsgView: clamp KEY_DOWN scroll to a cached _max_scroll instead of
over-incrementing and leaning on the next render to clamp
- DataStore: clamp use_lemon_font (>1 -> 0) on load, like the other enum fields
- move the ~1.5KB wrap scratch (trans/lines) off the render stack into shared
file-scope statics in FullscreenMsgView (single-threaded UI; the fullscreen
view and history list never lay out in the same frame)
Cleanup:
- drop dead members RingtoneEditorScreen::DUR_VALS and HomeScreen::sensors_scroll
- delete redundant manual scroll-clamps in handleInput across the drawList
screens (drawList already reclamps each render); remove the now-unused _visible
from QuickMsgScreen/NearbyScreen/BotScreen and BotScreen::scrollToSel()
Co-Authored-By: Claude Opus 4.8 <noreply@anthropic.com>
- drawList(): scrollable list skeleton (visible window, keep-sel-in-view,
scroll-column reserve, per-row callback, indicator). Migrate Tools, Bot,
Nearby, Waypoints list and the three QuickMsg lists onto it; centralises the
scroll-clamp/reserve/indicator that each had open-coded (and inconsistently).
- drawCenteredHeader(): centred title + separator, replacing the duplicated
two-liner across ~10 screens (incl. QuickMsg, which used width()/2 spacing and
was missed before); unifies the separator at headerH()-sepH().
- keyIsPrev()/keyIsNext() in UIScreen.h for the LEFT||PREV / RIGHT||NEXT idiom;
applied to 6 screens, behaviour-preserving. Cancel/context-menu stay
per-screen (they mean different things on different screens).
- rotLabel() dedups the 0/90/180/270 array in Settings.
- Unify selection-row height to lineStep()-1 (Tools/Bot matched the rest).

Pull repeated UI idioms into DisplayDriver and remove duplicated logic:
- DisplayDriver: add drawScrollArrows() and drawInvertedHeader(); replaces 11
copy-pasted scroll-arrow blocks across 5 screens and 3 inverted title-bar
blocks (NearbyScreen x2, NavView). Standardises the detail-view separator.
- useImperial(): single source on UITask; NearbyScreen/TrailScreen delegate
instead of each re-reading NodePrefs.units_imperial.
- NearbyScreen: extract saveSelectedWaypoint() (two identical blocks -> one);
drop the redundant local label buffer (WaypointStore truncates).
- UITask::shutdown(): power GPS off through LocationProvider::stop() instead of
poking PIN_GPS_EN directly — centralises enable/reset-pin + active-level logic.
Net -58 lines. Verified: GAT562 (SSD1306) and WioTrackerL1Eink (GxEPD) solo
builds compile clean.
Co-Authored-By: Claude Sonnet 4.6 <noreply@anthropic.com>
- UITask::shutdown(): power GPS off using !PIN_GPS_EN_ACTIVE instead of hardcoded
LOW, matching MicroNMEALocationProvider::stop() (still LOW on current active-high
devices, but correct for a future active-low GPS).
- buzzer _noteFreq(): clamp octave to 8 instead of 7 so the parser's accepted range
(4-8) is fully consumed; previously an octave-8 digit was clamped away and could
leak into the stream as the next note's duration.
- Waypoint::readFrom(): check read() return for version/reserved/count header bytes
so a truncated file is rejected instead of using garbage count.

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.

Reverts onDiscoveredContact to the upstream 4-param signature, adding a
separate virtual onDiscoveredAdvert(bool was_flood) with a default no-op
implementation. Only MyMesh overrides the new virtual; simple_secure_chat
and any future implementors need no changes on upstream merges.

USB client presence IS detectable on nRF52 after all: (bool)Serial ==
tud_cdc_n_connected() (DTR — a host has the CDC port open). Add
isClientConnected() = BLE-bonded OR USB-CDC-open; DualSerialInterface
overrides it, base defaults to isConnected() (single-transport unchanged).
Wire it so each consumer gets the right signal:
- hasConnection() ← isClientConnected(): Auto buzzer mute + message-wake now
trigger on BLE or an open USB port (PR #14's intent, done correctly), but
not on charging-only (no host → DTR low).
- BT status indicator + pairing PIN stay on isBLEConnected() (BLE-specific).
Caveat: a plain serial monitor also asserts DTR, so it counts as connected.

On a tall portrait e-ink panel the clock and lock screens wasted most of
the vertical space on a small inline "HH:MM". Render HH and MM on two
lines in a new size-4 font (built-in GFX scaled 7×, ~42×56 px) so the
digits roughly double in height and fill the narrow width. Wide panels
(OLED, landscape e-ink) keep the classic single-line size-2 layout.
- New shared drawClockTime() helper used by both the Clock home page and
the lock screen; returns the y below the time block so the date and
dashboard rows flow beneath it.
- GxEPDDisplay: size 4 = built-in font × BIG_TEXT_SCALE (7); getCharWidth /
getLineHeight / setTextSize handle it; fontAscender stays 0 (built-in is
top-left origin).
- Centre the big digits on their visible glyph width — the built-in font
advances 6 px per char but the glyph is 5 px wide, so getTextWidth over-
reports by one trailing column and the digits would sit ~half a column
left of centre. AM/PM rendered one size larger (size 2).

Before this commit, there was no way to set a different max hop count
for unscoped messages.
Now with this change, by defaul it tracks the flood.max setting, until
a user provides a flood.max.unscoped value, which tax precidence for
packets if ROUTE_TYPE_FLOOD is true.
Firmware (7-byte header):
Byte 7 = display->screenshotRotation() — GxEPD2/GFX rotation value (0-3).
DisplayDriver::screenshotRotation() defaults to 0 (OLED).
GxEPDDisplay::screenshotRotation() returns display.getRotation(), the
live GxEPD2 value (reflects runtime setDisplayRotation() calls, not just
the compile-time DISPLAY_ROTATION macro).
Python decoder:
- Parse 7-byte header; pass rotation to eink_buffer_to_image().
- Implement all four GxEPD2 drawPixel coordinate transforms:
rot 0: phys_x=lx, phys_y=ly
rot 1: phys_x=vis_w-1-ly, phys_y=lx
rot 2: phys_x=vis_w-1-lx, phys_y=vis_h-1-ly (180° flip)
rot 3: phys_x=ly, phys_y=vis_h-1-lx
- vis_w/vis_h derived from log dimensions + rotation parity (no constants).
- Print rot= in the status line so the user sees which rotation was used.
This fixes the 180° rotated image seen with rotation=2 (portrait inverted)
without hardcoding a flip — correct for any rotation value.

Firmware: add screenshotWidth()/screenshotHeight() virtual pair to
DisplayDriver (default: width()/height()). GxEPDDisplay overrides to
return display.width()/display.height() — the GxEPD2-reported values
that use WIDTH_VISIBLE (e.g. 122 for GxEPD2_213_B74), not the full
physical WIDTH stored in DisplayDriver (128). MyMesh uses these
instead of display->width()/height() for the screenshot header bytes.
Result for GxEPD2_213_B74 + DISPLAY_ROTATION=1:
header was 250×128 → now 250×122 (correct visible canvas)
Python decoder (tools/screenshot.py):
- Remove hardcoded EINK_PHYS_WIDTH=128 / EINK_VISIBLE_W=122 constants.
- Derive phys_stride from buffer_size / log_width (works for any panel).
- Fix phys_x formula: was (EINK_PHYS_WIDTH-1-ly = 127-ly),
now (vis_w-1-ly = log_height-1-ly = 121-ly for 213_B74).
Old formula addressed invisible columns 122-127; new formula correctly
maps logical rows 0..121 to visible physical columns 121..0.
- vis_w = log_height (no hardcoded trim; header now carries correct value).
This also works for square panels (e.g. 128×128 where WIDTH=WIDTH_VISIBLE):
header will carry 128×128, decoder produces a correct 128×128 image.

- Add lib/GxEPD2-patch/src/GxEPD2_BW.h: local patched copy of GxEPD2_BW.h
that exposes getBuffer()/getBufferSize() under ENABLE_SCREENSHOT guard.
Include guard (_GxEPD2_BW_H_) prevents double-inclusion of the installed
library version.
- GxEPDDisplay.h: use patched header via relative include when
ENABLE_SCREENSHOT so the patch takes precedence over the installed lib
(PlatformIO adds library paths before -I build_flags).
- DisplayDriver.h: add virtual getBuffer()/getBufferSize()/getDisplayType()
defaults (nullptr/0/0) under ENABLE_SCREENSHOT.
- SH1106Display.h / SSD1306Display.h / GxEPDDisplay.h: add concrete overrides;
getDisplayType() returns 0 (OLED) or 1 (e-ink).
- MyMesh.cpp/h: replace fragile C-cast with virtual dispatch in
handleScreenshotRequest(); extend 5-byte header to 6 bytes by appending
display_type so the host tool can decode the correct pixel layout.
- tools/screenshot.py: parse 6-byte header; add eink_buffer_to_image()
that decodes the row-major MSB-first GxEPD2 buffer with DISPLAY_ROTATION=1
(phys_x = 127-ly, phys_y = lx); dispatch on display_type.
- variants/wio-tracker-l1-eink/platformio.ini: add
[env:WioTrackerL1Eink_companion_dual_dev] with ENABLE_SCREENSHOT.
- variants/wio-tracker-l1/platformio.ini: unchanged (OLED env already exists).
Builds verified: WioTrackerL1Eink_companion_dual_dev SUCCESS,
WioTrackerL1Eink_companion_radio_ble SUCCESS (unaffected).

This is a consolidation of my changes for BME680 on RAK4631 nodes.
I will close my other PRs related to this and link back to this one.
*Background on change:*
This change replaces the Adafruit BME680 driver on RAK4631 with the
Bosch BSEC library. Other boards continue to use the existing
Adafruit path via ENV_INCLUDE_BME680.
This makes the IAQ portion of the sensor functional, and more accurate.
It also contains the math and/or CayenneLPP fixes from my other PRs.
The Bosch code also appears to handle calibrating sensor aging as well,
whereas the Adafruit code is just looking at blind values that can drift
with time. Pretty cool to see this shooting out useful data!
RAK4631 platform.io is set to override to ENV_INCLUDE_BME680_BSEC while
leaving the Adafruit code for other node types. (If this becomes applicable
for other node types in future, awesome! I just don't have hardware
to test against.)
Using the BSEC library introduces IAQ sensor calibration, and saves
the calibration state periodically so it does not have to calibrate
again later.
At startup the IAQ sensor takes 30 minutes to heat and to hit a baseline,
then starts calibrating. Once calibrated, it will save those settings
and will only write settings again if calibration falls back and restores
back to state 3.
This fix also has the gas resistance math fix that was in
[pull 2146](https://github.com/meshcore-dev/MeshCore/pull/2146) so
the adafruit path also can at least show accurate values instead
of looping negative.
Also includes the fix from [pull 2149](https://github.com/meshcore-dev/MeshCore/pull/2149) so the pressure output isn't truncated to 1hPa steps.
*Fixes/Changes:*
- Add bsec_config_iaq[] with the 3.3V/3s-LP/28d calibration profile
- BSEC init applies setConfig() for voltage-correct heater targeting
- IAQ, heat-compensated temperature/humidity, pressure, and altitude
reported over CayenneLPP
- IAQ accuracy reported as analog input over CayenneLPP (0,1,2,3)
- Calibration state persisted to /bsec_state.bin on nRF52 internal
flash; written only when iaqAccuracy improves to >= 2, should
keep write frequency well within flash endurance over device lifetime
- Fix non-BSEC query_bme680: float pressure division, addGenericSensor
for gas resistance (was addAnalogInput, overflows at > 327 Ohm)
- loop() correctly gated for both GPS and BSEC-only builds
- Add fix_bsec_lib.py extra_script to resolve nRF52840 hard-float ABI
mismatch in Bosch's PlatformIO packaging, silly Bosch
One general note outside of this code change: I noticed while BME680
_functions_ in companion nodes, since companion nodes run Bluetooth,
BLE preempts the CPU, and can do so mid-I2C-transaction.
This can cause the BME680 to see an anomaly and drop calibration and
start a recalibrate. This is behavior that will exist (and has existed)
regardless of using the Adafruit or Bosch paths.
This particular companion behavior does not seem to occur in sensor
or repeater nodes since their BLE is off. Probably affects other
I2C devices as well.
*Tests:*
- RAK19003
- RAK19007
- RAK19001
- repeater, sensor, companion
- 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
In GxEPDDisplay::print(), the 0xDB fallback block was drawn at
cy - 8*scale, which assumed the Lemon baseline convention
(cy = original_y + 8*scale). For the default GFX font fontAscender
returns 0, so cy = original_y (top of cell) — the block landed
16 px above the character on e-ink (scale=2).
Fix: draw at cy (top of cell) for the non-Lemon path.
Also remove the unused forceNextRefreshFull() virtual from
DisplayDriver — it was added based on a wrong hypothesis (partial
refresh ghosting) and was never wired into endFrame().
