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.
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.
Resolve Serial macro and ESP-NOW wrapper compilation errors. Preserve queue, neighbor, advert-history and Room post capacities while using qualified RTC, PSRAM and word-only IRAM storage on constrained ESP32 targets. Reduce Full infrastructure flash through lossless Room web compression, compact crypto and unused exception metadata removal.
Add focused native regressions for storage ownership, exact protocol output, OTA proofs and build policy. Keep physical flash sizes, OTA slots and RAM guard formulas unchanged.
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.

POST /api/room checked the room password on every request with no failure
limit, and a browser may send a new identity token each time. Any host that
reached WebConfig could guess the room admin password, which is also the
radio and /api/login admin password, at main-loop speed.
One budget now covers all browser tokens, with /api/login's numbers: at most
five distinct wrong passwords in each thirty-second window. After that, a
request carrying a password is refused without checking it until the window
ends. Wrong passwords count in read-only rooms too. Empty passwords are never
counted or refused, so public read-only access keeps working. The last four
wrong passwords are remembered by 8-byte SHA-256 digest and not counted
again, so a tab still polling with an old or mistyped password cannot use up
the budget. Successful sign-ins do not refund failures. Radio login is
unchanged.
test_room_web_service.py gains PASSWORD_LIMIT, which runs the real
processRoomRequest: refusal after five failures from five tokens; identical
replies for wrong, guest and admin passwords while refused, with no password
check (calls to authorizeRoomLogin are counted); no lock extension from 300
refused requests; the 29999/30000 ms boundary and the first window after
boot; read-only and empty-password cases; no refund on success; repeated,
rotating and read-only stale passwords; slow distinct failures ageing out;
and a guard that the digest ring stays in bounds. It fails on the previous
processRoomRequest at the sixth guess.

On a room server the guest password grants Read/Write, which the login
replay store treats as a role that needs a durable record. Every new
guest-password identity therefore took one of the 128 permanent slots,
and once they were used up the store failed closed for every new
identity, including a new administrator device, until the filesystem was
erased. Rooms often publish the guest password.
A guest-password Read/Write session (one without explicitly assigned
permissions) now uses the policy public readers already use: it must
beat its in-boot timestamp and any record the identity already has,
which is still advanced, but it never creates a new record.
Administrator logins and explicitly assigned roles keep the durable
reservation and still fail closed on a full store.
Tests: test_room_login_replay_capacity.py runs the real room login
handler against the real ClientACL replay store with ASan/UBSan: guest
churn cannot lock out a new admin or assigned writer, a former admin's
record still binds guest-password logins, and a store full of privileged
records still refuses a new admin. It fails 2 of 3 on the previous code.
Two expectations in test_room_login_integration.py and the login profile
contract follow the new policy.
