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.
Add the framed BLE mOTA transport and companion control path, complete the full-profile build and runtime fixes, and document and test the OTA workflow.
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.
* BasChatMesh: new onContactRequest(), for PAYLOAD_TYPE_REQ handling.
* companion, repeater and room_server: now with basic 'plumbing' to handle REQ_TYPE_GET_TELEMETRY_DATA (0x03).
* dependency: added CayenneLPP to libdeps
* all target.* modules now with a stub 'sensors' object.
