Received packets are uploaded before Mesh::onRecvPacket validates them, so
an advert corrupted over the air that still passes the LoRa CRC is published
with a mangled name or location. `set mqtt.advert.verify on` verifies each
received advert's Ed25519 signature (same message layout as Mesh.cpp,
including the 32-byte app-data clamp) and skips publishing failures.
Defaults off so collectors keep seeing RF corruption on the mesh. Dropped
adverts are counted as badsig= in `get mqtt.stats`. Exposed in the web
config Publishing card and persisted as mqtt.advert_verify in prefs JSON.
- Guard the boot-time link bootstrap to observer ESP32 builds. It ran
unconditionally in MyMesh::begin(), breaking every non-observer
repeater/room server build (ESP32 and nRF52).
- Rename NetworkInterface -> NetworkLink (class, accessor, files).
Arduino-ESP32 3.x ships its own NetworkInterface class and header,
which broke the ESP32-C6 builds. Drop WiFi.setAutoConnect(), a no-op
on 2.x and removed in 3.x.
- Refresh stored Wi-Fi credentials every bridge tick so the STA
reconnect loop picks up `set wifi.ssid` / `set wifi.pwd` without a
reboot, as the bridge did before the link moved out of it. Skip
reconnects while the SSID is empty.
- Restore the "WiFi connected: <ip>" / "WiFi disconnected: reason N"
debug lines the bridge used to print.
- Alert on Ethernet only once it has held a lease this boot or when no
Wi-Fi is configured; Wi-Fi-only installs of an Ethernet-preferred
image keep Wi-Fi alerts instead of reporting "Ethernet down".
- Record wifi.setup_complete only for Ethernet LAN onboarding, so
Wi-Fi builds keep the SSID-based first-boot portal rule.
- Use seq_cst for the route-switch lock/mutation flag handshake.
- Docs: SNMP RSSI sentinel is -127; describe link-return vs medium-switch
reconnect behavior accurately; note runtime credential pickup.
- Test: unknown keys inside a known /mqtt.json group are ignored, which
keeps wifi.setup_complete downgrade-safe.
`set display.flip 0|1` (also off/on) turns the panel 180 degrees from its
compiled DISPLAY_ROTATION, persisted in MQTTPrefs alongside display.timeout
and applied live without a reboot.
Adding 2 to the compiled rotation rather than setting an absolute value keeps
portrait portrait and landscape landscape, so the DisplayViewport geometry
never changes with it and the setting cannot produce a nonsensical mix.
DisplayDriver gains a defaulted no-op setFlipped(), so no other display
driver is affected.
The compiled rotation was verified identical across `pio run` and `build.sh`
on two machines (movi a11, 2 at the setRotation call site), yet the panel read
upside down for one tester and upright for another - which is what a board
mounted either way up looks like. No single compiled constant satisfies both,
so orientation becomes a setting rather than another rebuild.
Runtime-only, like display_timeout_secs: LegacyV1MQTTPrefs and the frozen
binary payload sizes are untouched, and the JSON group is an append that older
firmware skips.
Replace the sparse Heltec V4 R8 observer home screen with a padded dark
analytics dashboard, add manual display control, and make blanking a runtime
setting.
Dashboard (DISPLAY_ACTIVITY_DASHBOARD, the four R8 TFT observer envs):
- RadioActivityWindow: 20 one-minute buckets of valid RX packets, no heap.
The caller's 32-bit millis() is extended to a monotonic 64-bit clock, so
nothing downstream has a rollover case; an always-on node passes 2^32 ms
after ~49.7 days, which would otherwise re-enter warm-up and divide 20
minutes of traffic by seconds. Rates use 19 whole minutes plus the elapsed
part of the current one rather than a fixed 1200 s.
- ObserverDashboard: header, radio strip, headline totals, a 20-bar
packets-per-minute graph and RF/status footers, with separate portrait and
landscape layouts. A text row is a fixed 16 px, which is 3.2 logical units
in portrait but 4.27 in landscape, so one shared grid would overlap.
Text is trimmed by character budget, not measured width: getTextWidth()
reports an over-long string at the portrait driver's fallback scale, so
DisplayDriver::drawTextEllipsized() under-trims and the row renders at half
height.
- Six per-row signatures computed from what is actually drawn, so only the
rows whose pixels changed repaint. No startFrame(), no whole-screen clear.
Link state moved out of the full-frame signature, so a DHCP renewal or WiFi
flap repaints one footer row instead of the panel.
- Dark theme by retuning the UIColor statics at runtime, which needs no
display-driver edit and carries boot, setup, reboot and power-off with it.
Touch and button (DISPLAY_TOUCH_TOGGLE):
- CHSC6X at I2C 0x2E, polled; TP_INT is unusable (optional R13, and GPIO 43
is U0TXD). The point-count byte is tested against a valid count, never
against non-zero: an idle read returns 0xFF, which reads as a finger held
down forever and latches the tap detector after one event.
- turnOff() no longer parks PIN_TFT_RST low on this board. GPIO 21 is a
shared LCD_RST/TP_RST net, so doing that held the touch controller in
reset for as long as the display was off. Verified against Heltec's
expansion-board and mainboard schematics and the V4-R8 datasheet pinout,
which also correct the pin comment in HeltecV4R8Board.cpp.
- The USER button click now toggles the display too; it previously did
nothing whenever the display was already on.
display.timeout:
- `set display.timeout <secs>` / `get display.timeout`, 0 = stay on, 60 s
default, 3600 max. Read live, so a change applies without a reboot and
restarts the countdown rather than firing on the old deadline.
- Stored in MQTTPrefs (/mqtt.json), keeping NodePrefs aligned with upstream.
Runtime-only: LegacyV1MQTTPrefs and the four frozen binary payload sizes
are unchanged. No JSON format-version bump - the loader skips keys no
def() claims, so older firmware reads newer files and this firmware reads
older ones with the default applied. Both directions are covered by tests.
- Joins the observer atomic-setter contract, so a failed save rolls the live
value back instead of only claiming to.
New periodic work uses a wrap-safe deadline check; `millis() >= deadline`
fires every loop for a whole interval before each rollover.
Adds test_radio_activity_window, test_observer_dashboard (driving the real
renderer against a recording DisplayDriver in both orientation profiles) and
test_touch_tap_detector. 440 native cases pass.
Publishing moves the old primary to .bak before the verified temp takes
that name, so a failed second rename left the new image exactly where
boot recovery promotes it — while the observer setter told the operator
the change had been rolled back. The refused value came back at the next
reset.
Restore the backup and discard the temp on that path, and distinguish
CommitIndeterminate from CommitFailed when the filesystem cannot be put
back, so the CLI reply says the flash state is unresolved rather than
claiming the change is gone. The indeterminate condition latches for the
boot: the artifact left behind also makes every later transaction fail to
begin, so it cannot clear itself.
Also state the version-first rule the future-version probe depends on.
The probe reads the root version with this firmware's grammar, so a newer
file that introduces unknown syntax ahead of that field reads as corrupt
rather than future and loses its preservation guarantee.
Tests: publish-failure rollback and the indeterminate outcome against a
SPIFFS-shaped store fake; the version-first writer invariant and the cost
of violating it; /prefs.json coverage for the strict shape checks
(deployed-shape file, unknown nested groups, torn files, mismatches).
