Repeated preamble/header activity can keep a requested primary or TempRadio
change busy indefinitely. Bound unfinished-RX admission for accepted LR2021
changes while preserving completed packets, TX, BUSY and exclusive owners.
Ordinary scans and CAD keep their existing admission rules. Expose the failing
stage and native status through get radio.apply.
Add saved radio.xtrim capacitor calibration and measured radio.freqerror in
signed Hz from the last valid LoRa packet. Preserve native trim by default,
restore explicit calibration after resets/Morse, verify saves before applying,
wait two seconds for the acknowledgement, and roll back failed changes.
Calibration motivation and prior upstream work:
https://github.com/meshcore-dev/MeshCore/issues/3365https://github.com/recrof/MeshCore/tree/lr2021-trim
Packet-status format follows Semtech's LR20xx driver and RadioLib staging.
Tests execute production activity/admission and transaction paths with noisy
RX, completion races, protected owners, failed setters, RX restart and save
rollback. Physical W12 retuning and RF calibration still require confirmation.
Detect OLED or the original stock TFT touch assembly in ordinary V4.2/V4.3
images. Add saved live display.type auto/oled/tft/off selection and report
the active selection in board output. Keep sensors on primary I2C, preserve
shared power, and isolate TFT FSPI from radio HSPI through sleep and changes.
Consolidate future picker/build choices only with application capability
proof. Retain exact legacy OTA identities and separate R8 hardware images.
Document controls and physical qualification limits.
Validation: five serialized Full builds with capability/size/RAM checks;
focused host tests, existing R8/T-Deck/OLED regressions, build-profile suite,
and picker/provider tests. V4.3 OLED live changes and off/auto reboot
persistence passed on Mercerwood. Physical TFT qualification remains pending.
Temporarily disable incompatible cached side detectors while applying a temporary primary tuple, preserving their saved configuration for normal restoration. Use primary-only CAD while those detectors are suspended. Keep compatible temporary detectors and real hardware errors intact.
Report pending TempRadio starts instead of off, preserve live-tuple status during replacements and future schedules, and include the two-second delay in the accepted reply. Share primary validation to retain STM32 Mini flash capacity without dropping features.
Validated production CLI status, scheduler and persistence cases; LR2021 detector suspension, restoration, CAD and hardware-error paths; reply handoff, room/sensor recovery, Morse and OTA automation regressions. W12 repeater, room-server and sensor builds pass. Canonical STM32 Mini Repeater passes flash and runtime RAM admission with 436 bytes of flash remaining. Physical W12 RF testing remains unverified.
Fix the stale assertion reported by Actions run 40283205754. Ordinary room posts and topic pushes retain their configured delivery copies and ACK/retry behavior without opting into the admin CLI tx.reply policy. All 18 room-client path tests pass.
Persist set freq and set radio atomically, then apply through the existing safe radio scheduler without rebooting. Retain the old tuple until the delay and reply handoff finish, including queued room/sensor replies and TX-complete callbacks. End temporary sessions when accepting a permanent change.
Display applied RF settings even when radio2 is off. Share radio validation across immediate and scheduled setters to preserve STM32 Mini flash capacity. Update command documentation, regression coverage, and CI.
Validated production timing, persistence, display, CLI, fleet/reply, RX, sleep and Morse regressions. W12 repeater, room-server and sensor builds pass. Canonical STM32 Mini Repeater passes flash and RAM admission with 448 bytes of flash remaining. Physical W12 RF testing was not performed.
Fix the STM32 flash overflows and fleet fixture compile failure from
https://github.com/mikecarper/MeshCore/actions/runs/40241742182.
Fold already-unsupported RX control paths only for the integrated STM32WL
wrapper. Preserve RXPS-off validation, persistence, pending application and
rollback. External radios retain their supported controls.
Use measured GCC 14 code sharing in the four small STM32 USB Companion
recipes. Keep firmware features, contact/channel capacities, filesystem
boundaries and flash/RAM admission checks unchanged.
Refresh downstream host fixtures for saved radio intent, deferred service
restarts, WebConfig ownership, RX recovery and color tint state. Retain or
strengthen behavior checks rather than skipping failing coverage.
Validation: canonical RAK3x72, Wio Mini, Wio Dev and Tiny Relay USB Companion
packages and Mini Repeater build passed at release-version length. All
post-failure host checks, compact arithmetic/float checks, build-profile and
real PlatformIO recipe/path/RAM-policy checks passed locally.
Adapt upstream MeshCore #3579 at 7457cff43c22697119e06ad7d192a37de0990403:
retain GC1109 LF standby bias, with checked cold controls before band supply
changes and shutdown. Preserve exclusive LF/HF rails and TX error cleanup.
Reset before boot rail changes and before SPI-dependent hard recovery.
Retain our stronger implementation of #3512 at
d208bfef94ab83280de30ba4a0675ff73b3ecef3. Add regressions for suspect FIFO
contents, failed RX_DONE acknowledgement, and fresh preamble timing.
W12 TX power defaults from #3319 were already included via 65aa1138a.
Validation: 79 targeted native tests; canonical W12 Full repeater and Full
Companion builds, capability checks, app-size and RAM checks passed.
Physical W12 RF envelope, current and LoRa management confirmation remain.

Save valid busy RX, fast-switch and Companion tuple changes once, then
apply the latest accepted intent at a safe radio gap. Preserve checked-save
rollback, runtime RXEN intent, TempRadio ownership and exact remote reply
delivery. Repair failed preamble compensation without hiding uncertain saves.
Retry WebConfig, MQTT and NimBLE startup failures automatically. Preserve
explicit off choices, OTA ownership and the latest WiFi credentials through
cooperative shutdown. Add regression coverage and update command guides.
Validation: focused host transaction, rollback, ownership and lifecycle suites;
Full RAK4631, Heltec V4 R8 TFT and RC32 packages; representative room, sensor,
LR1110, LR2021, SX1276, STM32WL and ESP-NOW builds. Linked RAK crypto and OTA
workspace checks pass; its complete OTA image uses 712644/712704 bytes.
Default to one hour after sunset through sunrise, using fresh cached GPS or recent direct RF neighbor locations. Provide saved CLI and WebConfig controls with a small integer solar approximation and no additional framebuffer.
A settings save could reach the power setter while RX, TX, duty cycling or a
profile transition owned the radio, returning BAD_STATE after earlier settings
had already saved. Distinguish busy admission from a hardware rejection and
reuse the existing command route, storage and three-second deadline for power.
Acknowledge only after hardware acceptance and a successful preference save.
Skip hardware work for verified unchanged power. Invalidate that verification
after failed writes or radio initialization, retaining rollback and exclusive
beacon/Morse ownership. Keep the existing firmware memory limits and features.
Cover retries, captured routes, timeout/rollover, disconnect, partial writes,
failed saves and recovery. Keep ESP-NOW/simulation adapters compatible and add
ESP-NOW Companion compilation to the existing sequential smoke job.
An enabled MQTT bridge without a saved SSID forced WebConfig back on at boot,
even after set webui off. Its setup AP also suspended an enabled ESP-NOW bridge.
Use first-time MQTT setup as the default only when no WebUI choice is saved.
Apply the saved on/off setting afterward in Repeater and Room Server. Preserve
first-time provisioning and explicit starts.
Add executable boot regressions for both roles with unset, on and off WebUI
settings and configured/unconfigured WiFi. Update setup and picker guidance.
The extracted inbox renderer was missing HomeScreen's pairing PIN visibility
state. Provide it and check that it agrees with the complete PIN on screen.
Reuse the text drawing result instead of measuring pairing values twice, and
keep the bottom pairing layout separate from the large home renderer. This
saves 32 bytes in the RAK4631 Full Companion and lets its OTA image pass the
existing application limit without removing features or weakening checks.
Fixes the two failures in unit-test run 40174991783.

Preserve reserved fallback bytes for single-profile operation and UDP ingress. Clarify the protocol documentation and validate both UDP-enabled and UDP-disabled builds of the receive-profile helper.
Validation: receive-profile tags, response bounds, UART sessions, UDP packet origins, and bridge ingress tests passed.
