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.
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.
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.
Persist separate display modes and timeouts in seconds for battery and USB power, expose four controls in WebConfig and CLI, and apply one shared policy across display-equipped roles.
Detect R8 external power from a USB host or calibrated battery voltage above 4.21 V, with cached sampling and hysteresis. Add policy, persistence, browser, and R8 power-detection regression coverage.
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.
- Added getTextWidth method to DisplayDriver interface
- Implemented getTextWidth in all display classes
- Updated examples to use getTextWidth directly
