acidburns	5edb79f372	refactor(build): consolidate envs to production/debug/test; add compiler hardening flags ... - Replace 11 per-frequency build environments with 3 role-based targets (production, debug, test) using shared [env] base section - Move LoRa frequency and sender-ID config from build flags into config.h so all variants build from the same source - Add -fstack-protector-strong, -D_FORTIFY_SOURCE=2, -Wformat-security - Add Unity test framework to lib_deps for pio test support - Add __pycache__/ to .gitignore	2026-03-17 12:31:16 +01:00
acidburns	b9591ce9bb	feat(power): 1Hz chunked light-sleep; meter backoff; log throttling ... - Replace delay() with light_sleep_chunked_ms() in sender idle path (100ms chunks preserve UART FIFO safety at 9600 baud) - Add ENABLE_LIGHT_SLEEP_IDLE build flag (default: on, fallback: =0) - Meter reader task: exponential backoff on consecutive poll failures (METER_FAIL_BACKOFF_BASE_MS..MAX_MS) to reduce idle Core-0 wakeups - Configurable SENDER_DIAG_LOG_INTERVAL_MS (5s debug / 30s prod) - Configurable METER_FRAME_TIMEOUT_CFG_MS, SENDER_CPU_MHZ - New PlatformIO envs: lowpower, 868-lowpower, lowpower-debug - Add docs/POWER_OPTIMIZATION.md with measurement plan and Go/No-Go	2026-03-16 16:32:49 +01:00
acidburns	9c5b8fcdb4	Reduce sender power draw (RX windows + CPU/WiFi/ADC/pins) ... - Add LoRa idle/sleep/receive-window helpers and use short RX windows for ACK/time sync - Schedule sender time-sync windows (fast/slow) and track RX vs sleep time in debug - Lower sender power (80 MHz CPU, WiFi/BT off, reduced ADC sampling, unused pins pulldown) - Make SERIAL_DEBUG_MODE a build flag, add prod envs with debug off, and document changes	2026-02-13 23:56:36 +01:00
acidburns	e229efd427	Add payload codec test envs and enable serial debug	2026-02-13 23:56:36 +01:00
