1. v0.5.0 # Latest 4 months ago · 2026-02-14 16:53 UTC

   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

   Installation
