Standalone GPS beacon mode: when no KISS host is connected for 15s, the RNode transmits position and battery telemetry over LoRa. Two beacon paths: - LXMF (recommended): encrypted per-packet messages with announces, compatible with Sideband and any LXMF application. Supports IFAC network authentication. - Legacy JSON: plaintext or encrypted raw packets for simple collectors. Key changes: - GPS support for T-Beam Supreme S3 (L76K) and Heltec V4 (external) - SX1262 radio fixes: IQ polarity, DCD preamble lockup, RX reliability - LXMF identity management with NVS-backed Ed25519/X25519 keys - IFAC authentication (CMD_IFAC_KEY 0x89) for private networks - Per-channel serial isolation (USB, BLE, WiFi) - GPS status page in OLED display rotation - Provisioning via rnlog: provision-lxmf, provision-ifac - Documentation in Documentation/BEACON.md

# Workaround for ESP32-S3 rev v0.2 USB-Serial/JTAG controller bug:
|
|
# the USB controller drops after ~80KB of sustained compressed writes.
|
|
#
|
|
# This script splits the firmware into small page-aligned chunks and
|
|
# flashes each with a full device reset between them, keeping each
|
|
# transfer well under the ~80KB compressed limit.
|
|
# Only pauses on failure — successful writes proceed immediately.
|
|
#
|
|
# Usage:
|
|
# ./flash_parts.sh [port] [firmware_bin]
|
|
#
|
|
# Defaults:
|
|
# port = /dev/ttyACM4
|
|
# firmware_bin = build/esp32.esp32.esp32s3/RNode_Firmware.ino.bin
