v1.0.24: Node hash in WiFi config portal

What's new

WiFi Config Portal: Node Hash display

The captive-portal setup page now shows the device's Reticulum destination hash at the top, making it easy to identify the node without opening a terminal.

• Hash is cached in RTC memory after the first normal boot and survives software reboots into config mode
• Displays a friendly placeholder on first-ever boot (before RNS has started for the first time)

v1.0.23 — display orientation, DHCP recovery, transport mode note

Full Changelog: v1.0.22...v1.0.23

v1.0.22 — SF5 option in config portal

• Added SF5 as a selectable spreading factor in the configuration portal

v1.0.21 — Screen blank 5 min default, SF=5 option

• Screen blanking default set to 5 minutes (was 10 minutes)
• Added SF=5 as a supported spreading factor option

v1.0.20 — LED indicators & headless mode support

• LED indicators on V3/V4 (with or without display)
  • Solid: normal operation (radio online)
  • Fast blink: entering WCC config mode (button held >5s)
  • Slow breathe: WiFi Captive Configure portal active
• Headless mode: auto-detect missing OLED, operate without display
• Button press (1-3s) in WCC mode powers off; next boot enters normal mode
• Skip-config RTC flag only suppresses button-triggered re-entry, not unconfigured devices

v1.0.19 — Display blanking default 10 minutes

• Display blanking now defaults to 10 minutes (enabled by default)
• EEPROM-saved user preference still overrides

v1.0.18 — Rename to RTNode-HeltecV4

• Renamed project from RNodeTHV4 to RTNode-HeltecV4
• Updated firmware binary names to rtnode_heltec_v4.bin / rtnode_heltec_v3.bin
• Replaced 'boundary node' with 'transport node' in user-facing descriptions
• Updated OLED title bar to 'RTNode'
• Updated GitHub repo URL and flash utility references

v1.0.17

flash.py v1.0.17

Smart flash decision flow — settings never accidentally wiped

• App detection: Reads device at 0x10000 on connect. If no app firmware is present (blank flash), automatically does a full flash.
• Partition table check: If the device partition layout doesn't match expected, automatically upgrades to full flash.
• Clean decision flow:
  1. Detect board (reboot + flash_id)
  2. Check app exists - no app = full flash
  3. Check partitions match - mismatch = full flash
  4. Ask "Erase flash before writing?" - Y = full flash
  5. Full flash: merged binary at 0x0000
  6. Normal update: app-only at 0x10000 (settings preserved)
• Settings preservation: Normal updates extract the app portion from the merged release binary and flash at 0x10000, leaving NVS/EEPROM untouched.

Release binaries

• rnodethv3_firmware.bin — Heltec WiFi LoRa 32 V3 (8MB)
• rnodethv4_firmware.bin — Heltec WiFi LoRa 32 V4 (16MB)

v1.0.15: Default TX power to board PA_MAX_OUTPUT

v1.0.15 — TX Power Default

• Board-specific TX power default: Captive portal now defaults TX power to the board's PA_MAX_OUTPUT (V3=22 dBm, V4=28 dBm, other=20 dBm) instead of hardcoded 28
• PA_MAX_OUTPUT define: Added for V3 (22) in Boards.h, with fallback default of 20 for unknown boards

v1.0.14: Display blanking config in captive portal

v1.0.14 — Display Blanking Configuration

• Captive portal Options section: New display blanking timeout dropdown with options: Never, 1, 5, 10, 30, 60 minutes
• EEPROM format change: Blanking value now stored as minutes (was seconds), supporting timeouts up to 255 minutes
• Default timeout: Changed from 15 seconds to 1 minute

Previous changes (v1.0.12–v1.0.13)

• Link MTU clamping fix (70% transfer stall root cause)
• Echo-back prevention for TCP clients
• Oversized frame detection and drop
• Path discovery starvation fix
• flash.py auto-download with GitHub cache
