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:

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.
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.
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.
Add meter-reference calibration with saved ADC corrections, checked persistence and rollback. Preserve existing board coefficients and nRF52 voltage policy, and merge the Mini Repeater feature gates.
Validation: 69 focused tests, hosted documentation checks, and four firmware builds passed. Mini Repeater retains calibration and its existing filesystem with 376 flash bytes free; earlier Mini Sensor size failures remain documented.
Allow Auto, SSD1306 or SH1106 through display.controller on display-enabled RAK4631 and RAK3401 roles. Persist the choice before restart without changing the active screen policy, and let saved Auto override legacy build defaults.
Share checked settings I/O and the existing atomic writer to keep Full Companion within its flash boundary while retaining features and existing record formats. Cover save failures, backup recovery, startup selection and ambiguous OLED replies.
Validation: 35 targeted host tests passed. RAK4631 Full Companion and RAK3401 unified LoRa OTA repeater build and package checks passed with release-length version strings.
Add get leds and set leds on|off for Companion, repeater, room server and
sensor builds. Preserve the setting across reboots and cover GPIO, RGB,
Bluetooth, notification and expander indicators without changing radio
amplifier controls or screen backlights.
RAK Companions blink while advertising and keep the Bluetooth LED off once
connected, including late timer callbacks.
Adapted from meshcore-dev/MeshCore#3605 and #2694.
Validated with host regressions and firmware builds for SenseCAP Solar,
RAK4631, T096, Heltec V4, T-Beam, Xiao S3, Pico W and Wio E5 Mini.

Integrate upstream 1.18.0, delayed direct ACK forwarding, zero-scope routing, Waveshare LR1121 and dynamic WiFi variants. Preserve fork chemistry-aware power management and bounded multi-interface UI; retain retry/dedup safety while adding upstream ACK delay. Qualify LR1121 band power and HP-only Morse handling with native regressions.
Acquire fresh GPS and validated UTC, check an authenticated owner Companion, and apply saved lost-status cadence with bounded awake windows. Persist request tags, routes, and six-hour flood reservations; preserve the four-day cutoff across sleep and restart.
Keep Dispatcher recovery active after a failed radio wake, honor denied flood retries after lost TxDone, and qualify GPS ownership and clock corrections. Add executable regression tests and nRF52/ESP32 Sensor build jobs.
Validation: six firmware builds, 1829 native test cases, sanitized tracker/storage/GPS/sleep/recovery tests, and strict documentation build. Bluetooth Find My advertising and automatic Room mailbox polling remain separate work.
