Reticulum RNode Firmware for the Badge

RNode v1.85 for the 2024 DEF CON badge — turns the badge into a host-controlled 915 MHz LoRa transceiver for the Reticulum network stack (works with rnsd, NomadNet, Sideband, MeshChat).

Flash + provision

pip install esptool rns
esptool --chip esp32s3 --port <PORT> write-flash 0x0 rnode-1.85.factory.bin
rnodeconf <PORT> -r --platform 80 --product f0 --model fe --hwrev 1

Full instructions and interface config: firmware/reticulum/. Source, flash scripts, and Nibble Zero builds: RetiaLLC/NibbleReticulum (release v1.85).

Verification

Bidirectional badge ↔ Nibble Zero Reticulum link on hardware: 3/3 packets delivered with proofs at 914.875 MHz / SF8 / 125 kHz / CR5 (RSSI −45 dBm, SNR 11 dB).

⚠️ Never transmit without a 915 MHz antenna on the U.FL (J1) connector. Headless build — the TFT stays dark; the green debug LED blinks RX/TX.
