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.
Distinguish OTA read failures from missing blocks and select unique raw-flash checkpoints by MID and target. Keep deferred CLI requests and replies bound to immutable command identity and full authenticated keys.
Gate radio mutations on their exact reply delivery, recover coding-rate restoration, and roll back failed Companion preference writes. Preserve accepted low duty cycles across reboot.
Retain partial network writes, cancel displaced client operations, and reject malformed or stalled framed input. Add regression and CI coverage, and size-optimize the RAK4631 Ethernet build without dropping features.
Preserve resumed nRF52 flash pages and keep filtered OTA catalogs incomplete until full pages arrive. Bound stuck radio preparation, report companion setting failures, retain safe rollback, and codify conservative advert penalties with regression tests.
Cancel packets retained by the radio driver when their mesh retry is retired.
Echo-confirmed delivery completes application replies; explicit cancellation
releases failure references. Let active transmissions finish and prevent a
cancelled packet from returning after a driver timeout.
Preserve final direct-echo waits when only the other radio profile or crossover
policy changes. Recover verified radio-profile settings from backup even when
filesystem repair fails, and protect the backup after a failed save rollback.
Add regressions for direct and flood cancellation, confirmed command replies,
active TX completion and timeouts, subsequent packet cleanup, independent
profile echo ownership, and storage rename/removal failures.
Drain received packets in single-profile radio fault backoff as well as
dual-profile mode. Share the normal channel-clear and bounded busy policy
with driver retries so a failed send cannot retry blindly or bypass the
existing single-retry limit.
Retain an unadmitted OTA request flight and count v2 fallback evidence only
after a sparse retry enters the transmit queue. Local queue congestion no
longer disables v2 before a request was sent or discards received fragments.
Include primary airtime when temporary RX-only radio2 crosses requests onto
that channel, keeping response allowances conservative on slower profiles.
Add six native regressions, including five failing-before cases, and document
the queue-admission and crossover timing behavior.
Validation: 1,502 native tests, 29 integration checks, and five firmware
builds passed across ESP32-S3, nRF52, and STM32.
Keep catalog, manifest and leaf requests pending when the local transmit
queue rejects them instead of spending their network retry allowance.
Keep the packet selected before CAD so work becoming due during sensing
cannot bypass its own channel or pacing checks. Retire cancelled radio
retries before waiting for BUSY hardware or their retry deadline.
Wait for active transmission completion before applying firmware. Stop
admitting new transmissions after the apply drain deadline so busy queues
cannot postpone reboot indefinitely, and keep those deadlines armed across
millis rollover. Retain the existing persistence-flush backoff.
Add failing-before/fixed-after regression coverage for all four issues,
including the production OTA apply and TX guards in CI.
Validation: 1,496 native tests, 42 Python integration tests, and five
firmware builds passed across ESP32-S3, nRF52, and STM32 targets.
Add get/set ota.speed and OTA CLI aliases for factors from 0.05 to 3,
defaulting to the existing pace. Persist the setting independently of the
OTA workspace and apply it to OTA packet pacing, relays, discovery and
adverts while retaining the configured airtime budget.
Preserve physical proof/retry allowances, account for both participating
radio profiles, keep optional deadlines armed across millis rollover, and
exclude intentional pacing from observer stale-packet age. Keep local
verification at its normal rate and retain a valid saved speed if backup
recovery cannot finish. Add documentation and CI regression coverage.
Validation: 1,491 native tests and 26 CLI/integration tests passed. Built
ESP32 full repeater, ESP32 full Companion, nRF52 full Companion and STM32
USB Companion successfully, including their memory/size checks.
Persist Companion TX preferences per contact and channel. Default repeater,
room, and sensor replies to both active TX profiles, with a reply-only force
option for an RX-only secondary profile. Track both reply copies before a
temporary-radio handoff and account for OTA copies under queue backpressure.
Add bridge/crossover filter modes and the third built-in wardriving filter,
plus compact filter CLI syntax, documentation, and CI coverage.
Fix quoted target names being interpreted as slot/key selectors, partial
recovery of invalid saved reply settings, filter suspension during tempradio2,
and unnecessary packet allocation while OTA traffic is throttled.
Validation: 1,477 native tests, 52 Python integration tests, 29 filter UI tests,
and five firmware builds covering ESP32, nRF52, and STM32 passed.
Support fractional seconds, guard active packet work, keep the MCU awake, and restore reception after carrier tests. Include regression coverage and independent-radio RF validation for the V4 and T1000-E.
Implement radio2, tempradio2, radioat2 and tempradioat2 across Mesh roles,
with RX-only/RX+TX operation, optional preambles and persistent cross-TX
policy. Keep temporary OTA traffic on its profile by default and maintain
independent retry ownership and backoff for each profile.
Use slow-first receive scanning with 4.8-symbol visits and automatic
preambles rounded up in steps of eight. Preserve pending RX, restore power
saving on exit, and discard work bound to changed or expired profiles.
Restore the infrastructure path.hash.mode setter and report unsupported
extra.sf settings consistently. Add CLI, scheduling, scan and retry tests,
setup documentation, and the V4/XIAO hardware validation results.
Validation: 1,422 native tests, eight KISS tests, 63 final focused profile
tests, 18 checks from the staged source, sanitizer-enabled OTA transfers,
and builds for V4 Mesh roles, Full XIAO Companion and nRF52 T1000-E.
Hardware checks cover reception, cross-TX policy, expiry, reboot and OTA
discovery while receiving main-channel adverts.
Use RX-only radio recovery and feed the repeater reboot watchdog after MeshCore parsing. Default to 24 hours, apply temporary watchdog and advert intervals in RAM, and report temporary durations as days, hours, and minutes. Add regression coverage and an ESP-NOW bridge setup guide.
Bind Companion replies to request transports, make dual-CDC USB sessions nonblocking and reconnect-safe, and harden nRF52 watchdog/OTA storage paths. Fix T096 button debounce, display wake, sleep races, and the compact message layout; add exact WisBlock OTA profiles plus expanded native/static/HIL documentation.
Integrates Mike Carper's transmission-reliability work (direct retries with
SNR-adaptive backoff and CR, flood retry controls, alt-path replies, flood
channel gates) plus its upstream/dev base (as of 2026-07-06) on top of the
observer stack. The flex branch is untouched; this branch is the experimental
integration line.
Conflict-resolution decisions, for future re-syncs (git rerere is enabled and
has recorded these):
- NodePrefs adopts keymind/upstream member order + retry/flood tail. Member
order is in-memory only: /com_prefs stays field-by-field with the same
canonical file order both sides already share through offset 294; keymind
appends the retry tail at 295+ (new canonical size 676). Flex fleet files
load unchanged; retry fields default via direct_retry_prefs_magic.
- loadPrefsInt keeps the fork's legacy MQTT-gap recovery but moves its
detection boundary from 'extra > 5' to 'extra > LEGACY_MQTT_GAP_3SLOT (864)'
so keymind-size tails take the normal read path. COM_PREFS_TAIL_BYTES
retired.
- Dispatcher/RadioLibWrappers: fork watchdog additions + keymind TX overrides
and CAD busy counter are unioned; RxReservePacketManager::queueOutbound
follows upstream's new bool return (false when shedding).
- CommonCLI: fork observer dispatch + versioned /mqtt_prefs machinery kept;
keymind CLI (retry/flood/radioat) taken; duplicate CAD/FEM handlers and
sanitise lines deduped (kept keymind placements to minimize future diff).
- MyMesh (repeater/room): fork alerter/OTA/observer wiring kept; keymind
scheduled-radio system replaces the old pending_* temp-radio members;
applySavedRadioParams() replaces raw setParams at startup.
- ESP32Board: fork manifest-OTA + keymind powerOff/deepSleep and stopOTAUpdate
unioned; startOTAUpdate keeps fork's STA-aware IP with keymind's idempotency
guard.
- build.sh taken wholesale from keymind (fleet builds use GH Actions).
Verified: Heltec_v3_repeater_observer_mqtt, Heltec_v3_repeater,
heltec_v4_repeater_observer_mqtt, Heltec_v3_room_server_observer_mqtt build;
host migration harness (13 MQTT + non-MQTT scenarios) passes with updated
expectations (676-byte /com_prefs; odd-size files normalize on save, not
load); native unit tests 13/13.
