Use a 960-byte constant-time Ed25519 base table, compact hash/scalar code and unused-library trims while retaining Reader, BLE P-256 and the 8 KiB stack. RAK4631 Full saves 57,496 flash bytes and 3,152 static RAM bytes versus preview3.
Support complete chapters and verse ranges with bounded app continuation replies and cooperative terminal output. Use nonblocking TCP writes under reader backpressure. Add scalar/signature comparisons and a linked ARM crypto/stack CI gate.
Validated clean RAK4631, T1000-E, T096 and V4 Full builds, host regressions, and physical RAK chapter/reconnect and signing comparisons. Physical signing averages 35.9 ms versus 14.4 ms with the original table.
Port Meshtext settings to verified atomic nRF52 storage and use the existing radio RNG and hardware entropy. Keep the ExtraFS boundary, GPS, contacts, channel count and 8 KiB stack unchanged; omit unused library data to fit the image. Require linked codec and Companion transport evidence and build the real RAK Full profile in CI. Add configuration and storage-failure regression coverage.
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.
Save an opt-in off/no/yes answer to private Am I lost questions from known
chat contacts. Keep reply traffic and ACK state bounded, preserve pending
user delivery, and expose the setting through local CLI and ESP32 WebConfig.
Retain compact STM32 application/filesystem boundaries, qualify the Tag BLE
queue allowance, and exercise saved-image compatibility and browser controls.
Fix stale room mailbox protocol dependencies in the ACL/route test fixtures.
Validation: ten Companion builds, sanitized production-path regressions,
preference fault/compatibility tests, browser tests, and 86 capacity/build
recipe checks passed. No live radio was flashed for this feature.
Reject truncated anonymous reply paths and advert metadata before copying,
while preserving timestamp-only empty-password logins. Limit room posting to
read-write/admin ACL roles, retain inbox frames until the requesting transport
accepts them, and lock raw LittleFS traversal against concurrent writes.
Separate ISR event generations from main-loop radio state. Confirm RX/TX IRQs,
detach concrete wrapper callbacks safely, and discard inconsistent LR2021 FIFO
snapshots before rearming. Preserve bridge RX frames through packet-pool
exhaustion and bound ESP-NOW retries and missing-callback recovery. Screen RTC
register layouts without losing DS1307 startup, and ignore poisoned future
contact timestamps during clock bootstrap.
Keep the nRF52 loop stack at 8 KiB while reducing the OTA listing call chain
from 7,832 to 6,056 static bytes. Retain all target names through lossless Full
Companion compression and the canonical size optimizer. Preserve constrained
STM32 filesystems and bind corrected ESP32 UART/OLED budgets to source size
assertions. Document the separately measured preexisting W12 package limits.
Adapted for this branch from meshcore-dev/MeshCore PRs #3521, #3340, #3362,
#2062, #3503, #3038, #3534, #3544 and #3512.
Validation: 1,829 native tests; sanitized parser, inbox, LittleFS, ACL, clock,
RTC, IRQ/FIFO and bridge fault tests; 332 additional Companion cases; real
RAK4631 Full and both repeater profiles, G2 Full/standard, V3 Full and both
constrained STM32 release recipes. Radio-family compile coverage continues
separately; W12 full/portable package guards remain enforced.
Bound ACL replies for encrypted routes, authorize Sensor ACL access using the actual Admin role, and preserve request retries after failed queue admission. Validate stored paths for replies, while keeping Room keep-alives direct-only.
Add both G3 RF-slot Sensor profiles, suppress battery alarms on unavailable measurements, and remove the unsupported Sensor WebConfig capability. Add executable regression coverage and CI checks.
Keep the deployed SD target and layout, select qualified internal delta storage when no card is usable, and retain exact SD bootloader-update gates. Add storage, capability, transfer, recipe, and release-selection regression coverage.
Also preserve mandatory runtime packet logging in canonical XIAO images when verbose build debugging is disabled, fixing the four stopped release-matrix qualification failures.
Switch eight S3 board defaults and 78 remaining TinyUSB recipes to hardware Serial/JTAG while preserving UART and other platforms. Restore retained S3 PHY ownership after a TinyUSB OTA restart and prepare KISS queues before enabling the driver.
Add real recipe resolution, Companion/KISS transport sanitizer coverage, and RF lifecycle reset regressions to CI. Native tests pass 1765/1765; SDK, transport, recipe and USB watchdog checks pass. Board and role cross-compilation and physical OTA qualification continue.
Integrate PowerSaving-v17 through a27e78e4 (six new commits).
Use its 10-minute awake / 30-minute asleep companion GPS profile and
separate requested GPS state from receiver power in CLI diagnostics.
Include its nRF52 sensor debug-console settle delay and debug option.
Resolve overlapping GPS v2 changes using the current sensor callbacks,
which already implement live power-saving transitions, user-off control,
telemetry acquisition, wrap-safe sleep/wake timers and retained Airoha
RTC backup. Preserve preference persistence, telemetry cache/holds and
UART/shared-rail ownership safeguards across all four GPS drivers.
Add a compiled production GPS status regression test and run it in CI.
Validated 23 native GPS/power tests, preference and nRF52 pin contracts,
and firmware builds for T1000-E BLE Companion, MeshTracker X1 USB
Companion, Heltec Tracker Repeater, Mesh Solar Room and RAK4631 Sensor.
Import Airoha GPS RTC backup sleep, 24 contact search results, and the T-Echo Lite USB companion target. Preserve existing GPS telemetry and power-saving controls, crypto alignment checks, ESP32 RTC recovery, and RAK11310 dynamic-preference compatibility.
Validate GPS sleep acknowledgments with their NMEA checksum and add six native regression tests covering retry, drain, corruption, grace timeout, and timer rollover.
Verified: 1648 native and KISS modem tests; targeted nRF52, companion routing, one-key DM, and clock checks; T1000-E BLE, MeshTracker X1 USB, and T-Echo Lite USB companion builds.
