- Rename project from RNodeTHV4 to RTNode-HeltecV4
- Update GitHub repo URL, firmware binary names (rtnode_heltec_v4.bin, rtnode_heltec_v3.bin)
- Replace 'boundary node' with 'transport node' in README and flash.py descriptions
- Update OLED title bar to 'RTNode'
- Bump version to v1.0.18
Default behavior now checks GitHub for the latest release and downloads
firmware if the cache is empty or outdated. Cached binaries are stored
in .firmware_cache/{board}/ with SHA-256 integrity verification.
New flags:
--release TAG Flash a specific release version
--offline Skip online check, use cached/local firmware only
Removed --download flag (downloading is now the default).
Added .firmware_cache/ and rnodethv3_firmware.bin to .gitignore.
- flash.py: standalone flash utility with serial port listing, merge-bin,
GitHub Releases download, and esptool flash support
- Display.h: hide LAN row when Local TCP disabled, show local TCP port
instead of backbone port
- README.md: comprehensive documentation — Quick Start with 3 flash options,
OLED display layout, interface modes, routing customizations, path table
fix, interface name uniqueness, hardware rationale (PSRAM/flash)
- Release/boot_app0.bin: bundled for flash.py standalone use
- .gitignore: exclude merged firmware binary build artifact
Bridges LoRa mesh and TCP/WiFi backbone networks using microReticulum.
Based on microReticulum_Firmware with boundary mode additions:
- BoundaryMode.h: State management and EEPROM persistence
- BoundaryConfig.h: WiFi captive portal for configuration
- TcpInterface.h: TCP backbone interface with HDLC framing
- Display.h: Custom OLED layout with network status indicators
- Transport/Identity library patches for embedded memory constraints
