Configuration Parameters
| Parameter | Required | Type | Default | Description |
|---|---|---|---|---|
| EndPoint | Yes | string | - | AWS IoT Core endpoint (e.g., abcdef12345678-ats.iot.us-east-1.amazonaws.com). |
| ClientId | Yes | string | - | Unique client identifier for the connection. |
| PfxCertificate | Yes | string | - | Base64-encoded PFX certificate for X.509 authentication. |
| Port | No | int | 8883 | MQTT over TLS port (default is 8883). |
| UseTls | No | bool | true | Enable TLS encryption (should remain true for AWS IoT). |
| ValueMode | No | string | MeasureValueFields | Data serialization mode: MeasureValueFields or siemens. |
| QualityOfServiceLevel | No | int | 1 | MQTT QoS level (0, 1, 2). |
| MaxReconnectAttempts | No | int | 10 | Maximum reconnect attempts before backing off. |
| InitialReconnectDelayMs | No | int | 1000 | Initial reconnect delay in milliseconds. |
| MaxReconnectDelayMs | No | int | 30000 | Max reconnect delay in milliseconds. |
| MessageBatchTimeoutMs | No | int | 500 | Batch window for outbound publish. |
| MaxBatchSize | No | int | 50 | Max messages per batch. |
| HealthCheckIntervalSec | No | int | 5 | Connection health check interval. |
| ConnectionTimeoutSec | No | int | 5 | MQTT connection timeout. |
[!NOTE] AWS IoT Core requires a valid device certificate. Make sure the device is attached to an IoT Thing and policies allow publish.
Message Format
Each payload entry is sent as a flat JSON message. The format matches the Azure IoT connector for consistency.
Default Mode (MeasureValueFields)
{
"deviceId": "dev-1",
"deviceName": "sensor-1",
"measureName": "Temperature",
"timestamp": "2024-02-01T00:00:00.000Z",
"measureValueType": "DOUBLE",
"measureValueDouble": 25.5
}Siemens Mode (siemens)
{
"deviceId": "dev-22",
"deviceName": "line-2",
"measureName": "Status",

"measureValueType": "BOOLEAN",
"value": "true"
}Internal Behavior
Authentication & Security
- X.509 Certificates: Uses AWS IoT Core's recommended X.509 certificate authentication
- TLS 1.2: Mandatory TLS encryption with certificate validation
- Device Identity: Each connection represents a unique IoT device in the registry
Performance Features
- MQTT Protocol: Uses standard MQTT for efficient IoT communication
- Message Serialization: Flexible data serialization supporting flat message structures
- Connection Management: Robust connection handling with automatic reconnection
- AWS Service Integration: Ready for integration with AWS IoT Rules, Lambda triggers, and DynamoDB
