    Quiet Hours + Circuit Breaker + Adaptive TX Power

    Three new features leveraging the existing SNR/RSSI infrastructure to improve reliability, power savings, and mesh network resilience.

    • Quiet Hours — Configurable night-time rate limiting (e.g. 22:00-06:00) reduces forwarding from 100 to 30 packets/min. Saves battery during low-traffic periods. Requires TimeSync.

    • Circuit Breaker — Automatically blocks DIRECT forwarding to neighbours with degraded links (SNR < -10dB). Transitions to half-open after 5 minutes for a test packet. Good SNR closes the breaker. FLOOD traffic is never blocked.

    • Adaptive TX Power — Dynamically adjusts transmit power (5-14 dBm EU) based on average neighbour SNR. Reduces power when signal is strong, increases when weak.

    What's New in v0.4.0

    Bug Fixes

    • Battery ADC fixed - Resolved 0V battery reading caused by CubeCell framework 1.6.0 bug (ch3 SAR calibration not initialized). New workaround uses analogRead() + ch0 calibration + VBAT_ADC_CTL circuit control
    • Airtime tracking - RX/TX airtime now properly calculated per-packet using LoRa formula
    • Noise floor estimation - EMA-smoothed noise floor from RSSI-SNR, no longer stuck at 0dB
    • Remote CLI commands - Fixed "Err:Unknown" for commands only available on local serial

    New Features

    • radiostats command - Noise floor, last RSSI/SNR, airtime TX/RX (serial + remote)
    • packetstats command - Packet breakdown: flood/direct RX/TX (serial + remote)
    • lifetime command - Now available via remote CLI (was serial-only)
    • tempradio command - Temporary radio parameter changes without saving to EEPROM

    Optimizations

    • Flash savings: 2,904 bytes - String abbreviation in LOG/LOG_RAW macros (98.3% → 96.0%)
    • Startup banner simplified (removed unicode box-drawing characters)

    Documentation

    • Complete command reference tables in README
    • Corrected radio parameters (frequency, TX power, sync word)

    Build Info

    • Flash: 96.5% (126,492 / 131,072 bytes)
    • RAM: 51.3% (8,408 / 16,384 bytes)
    • Board: Heltec CubeCell HTCC-AB01
    • Region: EU868
  3. v0.3.3 # 5 months ago · 2026-01-23 21:37 UTC
    View release ↗

    Features

    • MeshCore Protocol Compatible - Works with MeshCore Android/iOS apps
    • Ed25519 Authentication - Secure login with encrypted sessions
    • Rate Limiting - Protection against brute-force and flood attacks
    • Persistent Statistics - Lifetime stats survive reboots (EEPROM)
    • Neighbour Tracking - Direct repeater discovery via 0-hop ADVERTs
    • Remote CLI - Encrypted command access via mesh network
    • Deep Sleep - Low power mode support

    What's New in v0.3.3

    • Added persistent statistics stored in EEPROM
    • Tracks lifetime: RX/TX/FWD packets, unique nodes, logins, uptime
    • Auto-save every 5 minutes with CRC16 integrity
    • New commands: lifetime, savestats
    • Boot counter for reliability monitoring
