  "t": "log",          // Type: log/cmd/evt/res
  "id": "123",         // Message ID
  "src": "app1",       // Source identifier
  "ts": 1234567890.1,  // Timestamp
  "d": {}              // Data payload
}

Transport Methods

• ZeroMQ IPC - High performance local communication
• WebSocket - Browser compatibility and remote access
• HTTP REST - Simple API endpoints
• Local buffering - SQLite for offline operation

🔧 Extended Protocols Support

I2C - Sensor Communication

# Read BME280 environmental sensor
from protocols.i2c_handler import I2CHandler

i2c = I2CHandler(simulator=True)
data = i2c.read_bme280()
print(f"Temperature: {data['temperature']}°C")
print(f"Humidity: {data['humidity']}%")
print(f"Pressure: {data['pressure']} hPa")

# Scan I2C bus for devices
devices = i2c.scan_bus()
print(f"Found devices: {[hex(addr) for addr in devices]}")

I2S - Audio Processing

# Generate and play test tone
from protocols.i2s_handler import I2SHandler

i2s = I2SHandler(simulator=True)

# Generate 440Hz tone
audio_data = i2s.generate_test_tone(440, duration=1.0)
i2s.play_audio(audio_data)

# Record and analyze audio
recording = i2s.record_audio(duration=2.0)
fft_data = i2s.analyze_audio_fft(recording)

RS485/Modbus - Industrial Communication

# Control Variable Frequency Drive
from protocols.rs485_handler import RS485Handler

rs485 = RS485Handler('/dev/ttyUSB0', simulator=True)

# Read holding registers from device
data = await rs485.read_holding_registers(slave_id=1, address=0, count=2)

# Write VFD speed control
await rs485.write_holding_register(slave_id=3, address=0, value=8000)  # 80% speed
