ARGUS REDLINE v0.1.03

Highlights

• Moved Hub and Node identities out of protocol.h
• Added per-environment device IDs through PlatformIO build flags
• Added include/device_config.h
• Added compile-time checks for missing or conflicting IDs
• Preserved the existing Protocol v0.1 wire format

Validation

• Hub build: PASS
• Node build: PASS
• Hub flash on COM4: PASS
• Node flash on COM5: PASS
• 13 consecutive command/ACK exchanges verified
• Sequences 9–21 acknowledged without retries or malformed responses
• Addressing verified as Hub 1 → 16 and Node ACK 16 → 1
• CodeQL checks: PASS

ARGUS REDLINE v0.1.02

Highlights

• Added formal opcode ranges for core, application, and reserved use
• Added a typed Opcode registry
• Preserved compatibility with OPCODE_TEST
• Added centralized supported-opcode validation
• Added command payload-length validation
• Added ACK status validation before enum conversion
• Updated Hub ACK matching to use the transmitted command opcode
• Updated Hub and Node startup reporting to v0.1.02

Validation

• Hub build: PASS
• Node build: PASS
• Hub flash on COM4: PASS
• Node flash on COM5: PASS
• 10 consecutive command/ACK exchanges verified

ARGUS REDLINE v0.1.01

Highlights

• Replaced the Node's blocking receive cycle with continuous asynchronous startReceive()
• Added DIO1-driven RX and TX completion handling
• Added explicit LISTENING and TRANSMITTING_ACK states
• Converted acknowledgment transmission to asynchronous startTransmit()
• Preserved Protocol v0.1 addressing, validation, duplicate suppression, cached ACK replay, and opcode handling

Validation

• Hub build: PASS
• Node build: PASS
• Hardware flash on COM5: PASS
• 18 consecutive command/ACK exchanges verified
• Sequences 216–233 acknowledged without loss
• No periodic receive timeout cycle observed

ARGUS REDLINE Protocol v0.1.0

ARGUS REDLINE Protocol v0.1.0 establishes reliable bidirectional binary LoRa communication between a Hub and Node running on Heltec WiFi LoRa 32 V4 hardware.

Verified capabilities

• Versioned six-byte binary packet header
• Explicit source and destination addressing
• Command opcode support
• Sequence-matched acknowledgments
• Packet-length and packet-type validation
• Bounded acknowledgment retries
• Duplicate-command suppression
• Cached acknowledgment replay
• Automatic recovery after temporary Node loss
• RSSI and SNR serial diagnostics

Hardware tested

• 2× Heltec WiFi LoRa 32 V4
• ESP32-S3
• Semtech SX1262
• 915 MHz LoRa configuration

This remains experimental development firmware and is not intended for safety-critical reliance.
