Run DHCP and renewal in a cooperative worker, bound socket commands, and retain SPI ownership until cleanup is safe. Preserve framing deadlines, response ownership and whole-frame replay, including pending-ACK queue pinning.
Budget the worker additively and retain all OTA names with an exact-checked Full-only compact index. Add full-driver, sanitizer, queue, shutdown, storage and memory regression coverage.
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.
Share one bounded WiFi outage and recovery schedule across MQTT, automatic NTP, Companion station ownership and WebConfig. Preserve enabled settings and foreground access while allowing normal sleep after confirmed physical shutdown.
Honor failed SDK client stops before handing off WiFi, protect clean teardown and reconfiguration, and retry transient ESP-NOW channel restoration without repeated disconnects. Add production-method, SDK failure and real sleep regressions to CI.
Validation: native MQTT/NTP/clock/reconnect suites; production power and wrapper failure tests; browser, room HTTP, OTA and combined bridge regressions; Full Heltec V4 repeater, room and companion builds with capability, flash and linked-memory checks.
Starting or restarting MQTT during browser OTA could remove the active AP by forcing STA mode. Defer shared MQTT startup and recovery, and Companion WiFi startup, pending credential reloads and saved-SSID retries, until the live SDK AP releases the driver. Preserve the setup owner's deliberate credential handoff and cooperative stop acknowledgement.
Validated 91 source host tests, including 20 new AP ownership cases and nine reverted controls under ASan/UBSan. Hardware and firmware build qualification remain separate; the Arduino mode snapshot is not atomic.
Report the upload address and required network, honor AP switches on an existing uploader, and keep delayed WebConfig cleanup from disabling OTA WiFi. Preserve actionable startup errors and account for OTA in wireless state controls.
Exercise the production OTA lifecycle and stock website console, including power-saving idle sessions, in host regression tests.
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.
