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.
Use a bounded timed OTA forwarding cache while preserving echo, queue, TempRadio and forwarding-policy guards. Add opt-in manifest recovery for directly reachable legacy relays and interactive 125 kHz SF5/SF6/SF7 rehearsals, with regression tests and documentation.
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.
Accept preamble-bearing TempRadio status from newer firmware while retaining legacy replies. Keep the 20-minute hard minimum but make the 120-minute and timeout estimates advisory, with a window-only override. Add parser, rehearsal, relay identity, and RAK bootloader regression coverage.
