- 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
- V3 board profile defaults to DIO flash mode (QIO fails on some flash chips)
- flash.py: auto-verify on --erase/--full, post-flash boot monitoring with
auto-DIO retry on bootloop detection
- flash.py: erase keeps device in download mode (--after no_reset) to prevent
race condition on re-entry
- flash.py: remove --dio/--verify flags (now automatic), hidden --flash-mode
for power users
- RNode_Firmware.ino: release BT memory (~70KB) on V3 boundary where BT is
compile-time disabled
- RNode_Firmware.ino: add WDT resets throughout setup() to prevent timeout
during long init sequences
- RNode_Firmware.ino: fix while-not-Serial blocking on V3 (no USB-CDC)
- RNode_Firmware.ino: init bt_devname from WiFi MAC when BT disabled
- RNode_Firmware.ino: bootloop detection via RTC_NOINIT_ATTR -- forces config
portal after 5 rapid reboots
- 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
- Fix path table insert bug: C++ map::insert() silently fails when key
exists (unlike Python dict[key]=value). Changed to erase()+insert() so
updated paths (e.g. local TCP replacing stale LoRa) actually take effect.
- Add name parameter to TcpInterface constructor to give each instance a
unique identity hash, fixing map collision between backbone and local
TCP server interfaces.
- Set TCP interface bitrate to 10 Mbps (was 500 bps) so Transport
correctly prefers TCP paths over LoRa when both exist.
- Add PRG button hold >5s white screen indicator for config portal.
- Boundary mode cull_path_table: evict backbone paths first, preserving
local paths needed for inbound routing.
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
