- GxEPDDisplay now uses the same single misc-fixed 6x9 font as the OLED
driver (Lemon retired there too), with baseline math updated for the
new ascent.
- Clock Tools' Alarm screen: Repeat and Armed now respond to LEFT/RIGHT
like every other multi-value/toggle field in Settings, not Enter-only;
Hour/Minute merged into one Time row edited with a hand-rolled HH:MM
digit cursor (like the Timer's), replacing the two-row DigitEditor
popups; Repeat's "Off" label now matches the codebase-wide ON/OFF
casing.
- Top status bar: battery icon now shares the same box height as the
other status icons (Bluetooth/mute/etc.) instead of standing 2px
taller, and its charge nub is properly vertically centred instead of
drifting off-centre at non-multiple-of-4 box heights.
- Small settings-gear icon glyph tweak; wio-tracker-l1 screenshot build
variant now enables DUAL_SERIAL.

Replace the Lemon/default font-switch with a single misc-fixed 6x9 font
(full Latin/Greek/Cyrillic coverage), generated via a new tools/bdf2gfx.py
BDF-to-GFX converter. Removes the keyboard's per-render font-switch
workarounds now that one font fits its cell cleanly.
DiagnosticsScreen becomes a circular tab carousel (Live / System / Font),
adding a firmware+device+radio info tab and a per-alphabet rendering test
card covering every keyboard language.

After soaking for a bit on the adverts without issue on multiple nodes,
I added more hardware crypto.
Supported nodes is unchanged in this PR addition, but if others can verify,
they can easily be added.
Some info on the CC310: https://docs.nordicsemi.com/r/bundle/ps_nrf9151/page/cryptocell.html
**Added:**
- AES-128 packet encryption/decryption now use hardware crypto
- HMAC-SHA-256 authentication now uses hardware crypto
- ACK hash computation and channel ID derivation now use hardware crypto
- RNG (random number generator) now uses hardware crypto rather than
radio noise + weak software RNG (which can have issues if there's
no surrounding radio noise.) NIST SP 800-90B certified.
- Runs hardware self-tests on startup
- Runs continuous health tests during operation
- Uses thermal noise/shot noise for randomness
**Unchanged:**
- calcSharedSecret remains software - it would be a split hw/sw solution
and added complexity for likely not a lot of gains. This only happens
when establishing a new contact, so not too frequent to be worth it.
- ed25519_create_keypair remains software. This is only called when a
node is first initialized. It does use the hardware RNG change, however,
so better randomization.
Tested on (so far):
- Heltec t096
Build test on:
- Heltec t096 companion ble
- t1000e companion ble
- RAK 4631 repeater
- RAK 3401 companion BLE
- Heltec v3 companion wifi
next_check and next_gps_update stored a future millis() value in a signed
long and compared with a naive '>'. After the ~24.8-day millis() sign flip
the deadline sits above the wrapped millis(), so the block never runs again
and GPS->RTC time-sync (and the location cache refresh) stall permanently
until reboot. Switch to unsigned deadlines with the wrap-safe signed-
difference compare '(long)(millis() - deadline) > 0', matching the idiom in
Dispatcher::millisHasNowPassed.
Also: reorder the MicroNMEALocationProvider ctor init-list to declaration
order (silences -Wreorder) and drop the always-true 'if (_claims > 0)' guard
in claim() (claim() always runs after _claims++, so it is >= 1).
- Context menus (PopupMenu, Nearby/QuickMsg call sites) go back to centring on
screen; the header's discoverable-menu glyph stays, but dropping the popup
out of its corner looked bad on some screens.
- Unread pill badge digit wasn't centred: Adafruit_GFX's classic built-in font
(SH1106/SSD1306) always pads a measured string by one trailing advance
column regardless of the glyph drawn, so centring on the raw width left 1px
more slack on the right than the left. New DisplayDriver::
textWidthTrailingGap() (0 by default) corrects for it on those two backends.
- On-device room Logout: mirrors the app's CMD_LOGOUT (drops keep-alive
tracking, forgets the saved password) so a room can be deliberately signed
out of from the Room options menu, not just re-logged-in.
Not build-verified — no PlatformIO toolchain available this session.
Previously load() returned true unconditionally on file-open success,
masking truncated or corrupt /regions2 files. Additionally, the first
field of each entry record (r->id) used the same success-chaining
pattern as subsequent fields, so a clean EOF at a record boundary set
success=false and would have been indistinguishable from real
corruption once the return value was fixed.
The r->id read is now split out: n==0 is a clean EOF (break, success
retains its prior value from the header read), n!=sizeof(r->id) is a
partial read or corruption (break, success=false). load() now returns
success instead of an unconditional true, so its return value reflects
the actual parse outcome.
Companion fix to #2372, which fixed the same return-true hardcoding
in save(). (#1891 originally reported this on load() but was closed
when #2372 landed — that PR only touched save(); this addresses the
load() side.)
Hold-Enter context menus were invisible. Add a menu affordance to every screen
that has one:
- A small ≡ glyph in the header's top-right, via new DisplayDriver::
drawContextMenuHint() and an optional menu_hint arg on drawCenteredHeader() /
drawInvertedHeader() (reserves the corner so the title never runs under it).
- The glyph highlights (corner cell filled, bars knocked out) while the menu is
open, tying the hint to the popup it spawned — driven by a menu_open flag the
screens pass from their live popup state.
- The context menu now drops out of that corner: PopupMenu gains an opt-in
top-right anchor (begin(..., anchor_top_right)); it right-aligns under the
header instead of centring, so the menu reads as emerging from the ≡. Default
stays centred, so non-context popups (Tools/Settings/etc.) are untouched.
Enabled on Nodes (list/scan/detail) and Messages (mode select, contact/room and
channel pickers, DM and channel history).
Both solo envs build green.

UI-polish trio from CODE_REVIEW (biggest "feels finished" gain per line):
- Pill unread badges: new DisplayDriver::drawUnreadBadge()/unreadBadgeWidth()
draw a filled capsule with the count knocked out (corners knocked back for a
rounded look; inverts on a selected row). Replaces the bare right-aligned
digits in MODE_SELECT, the contact/channel pickers and favourites tiles.
No <stdio.h> in the header — fmtBadgeCount formats manually, clamps to 99+.
- Unified DM/CH history headers: DM_HIST and CHANNEL_HIST drew their titles by
hand (drawTextCentered + fillRect at lh+1), a different height/separator than
every other screen. Both now route through drawCenteredHeader().
- Trimmed default home carousel: new NodePrefs::HP_DEFAULT (Clock, Tools,
Shutdown, Favourites, Map; Messages + Settings always visible = 7 pages).
applyDefaults() seeds it instead of HP_ALL. Recent/Radio/BT/Advert/GPS/Sensors
are opt-in via Settings > Home Pages. Existing users keep their saved mask —
factory default only; no migration, no schema bump.
Both solo envs build green (OLED RAM 69.9%/Flash 62.8%; e-ink SUCCESS).

A full (non-partial) refresh on every screen change (638eea7b) turned out to be
far too aggressive on real e-ink hardware: every navigation black-flashes,
which is worse than the ghosting it was clearing. Remove the whole mechanism —
DisplayDriver::forceFullRefresh() virtual, GxEPDDisplay's _force_full flag and
override, the endFrame() branch, and the setCurrScreen() call. E-ink is back to
interval-only full refreshes (Settings > Full refresh interval).
The favourites "(gone)"-tile prune that shipped in the same commit is kept.
Builds green: WioTrackerL1Eink_companion_solo_dual.

Two UI quick wins from the 2026-07-05 review:
- E-ink: force a full (non-partial) refresh on the first frame of a new
screen. Inter-screen ghosting was the most visible cheap win — the
N-partials interval alone doesn't catch navigation. New
DisplayDriver::forceFullRefresh() (no-op on OLED), set in setCurrScreen()
and consumed by GxEPDDisplay::endFrame().
- Favourites: clear a stale "(gone)" tile at render time so it reverts to an
empty "+" slot. Happens when prefs outlive the contact list (e.g. a wiped
/contacts3); onContactRemoved only catches a live delete. Pruned slots are
persisted once per pass (self-healing — an emptied slot can't re-fire).
Builds green: WioTrackerL1_companion_solo_dual (OLED),
WioTrackerL1Eink_companion_solo_dual (e-ink).

The SH1106 path always pushed the full 1 KB buffer over I2C every endFrame,
even on static screens (clock, home) that don't change between updates. Hash
the GFX buffer (FNV-1a, no external dep — the CRC32 lib is only wired into
e-ink builds) and skip display.display() when it matches the last frame
pushed. _force_redraw forces a flush on the first frame and after
turnOn()/clear() so a post-wake or post-clear frame can't be wrongly skipped.
Mirrors the existing e-ink CRC-skip. Builds green: WioTrackerL1_companion_solo_dual.

GPS support was implemented incorrectly for the ThinkNode M3. The reset
pin was being driven when it should be left floating for this unit. The
enable pin also wasn't being picked up by `MicroNMEALocationProvider`
because of a mismatch in constant naming conventions. I did a general
cleanup of the GPS and ThinkNode M3 bring-up code so that constant names
line up and "*_ACTIVE" constants are used consistently vs hardcoding
`HIGH`/`LOW`. After making these changes, serial data immediately starts
streaming in from the NMEA on boot and GPS detection just works.
LED handling was also not quite right for the ThinkNode M3. The LoRa TX
LED was being driven high to turn it on when it should actually be
driven low. I changed the code to use the `LED_STATE_ON` constant and
also added a little code to the shutdown path to properly make sure that
all LEDs are turned off.
Tested and confirmed working on real hardware.
Resolves both #1864 and #2879.
hasSeen() was simultaneously a predicate and a mutator — it inserted the
packet hash on every miss, making five call sites that only wanted to mark
a packet as sent call it with the return value discarded.
Split into:
- wasSeen() — pure predicate, no side effects
- markSeen() — explicit insert
All query sites now call markSeen() immediately after wasSeen() returns
false, preserving identical runtime behaviour. The five mark-only send
sites (sendFlood, sendDirect, sendZeroHop x2) now call markSeen directly.
Also fixes three bridge sites (BridgeBase, ESPNowBridge, RS232Bridge)
that had the same query+implicit-insert pattern.
Tests: add test/test_mesh_tables/ covering wasSeen purity, markSeen,
dup stats, and clear. Update SHA256 mock to produce deterministic output
(previously finalize() was a no-op). Add Packet.cpp to native build filter.
A single button press could surface as two CLICKs on the e-ink build, most
visibly as start+stop on the stopwatch. Two contact-bounce paths fed the
IRQ edge-capture machinery a phantom press/release pair:
- a bounce edge accepted just after a clean release was replayed as a real
press — ISR_DEBOUNCE_MS (5 ms) was too short for the joystick switch; raised
to 25 ms so the settling burst is swallowed.
- the live-pin self-heal reconciled prev against a single raw digitalRead,
which can sample a bouncing contact mid-flap and synthesise a transition.
It now acts only once the divergence has been stable for ISR_DEBOUNCE_MS, so
a momentary read can't inject a click; a genuinely lost edge still heals
(~25 ms later) so the button can't stick.
Both thresholds stay far below any human tap cadence (>100 ms), so rapid
multi-tap navigation still registers every tap.
