Ingesting signal data using ingestSignalValueByName in FleetWise Edge SDK

[surajnagargoje05]

I'm trying to use the FleetWise Edge SDK to ingest signal data into AWS Cloud, but I'm having trouble finding documentation or examples on how to do so using the ingestSignalValueByName function in IoTFleetWiseEngine.cpp.

My use case is as follows: I have a database containing signal names and their corresponding values, and I want to send this data to AWS Cloud using the FleetWise Edge SDK. However, I'm not capturing data directly from the CAN bus like most examples demonstrate. Instead, I need to inject this signal data into the SDK.

The ingestSignalValueByName function seems like the right approach, but since it's not being called in any of the available examples, I'm struggling to understand how to use it correctly.

Has anyone successfully used ingestSignalValueByName to ingest signal data into FleetWise Edge SDK? If so, could you please share an example or provide guidance on how to do so?

I'd greatly appreciate any help or information that can be shared on this topic.

Hi @surajnagargoje05, using the "Network Agnostic Data Collection" (NADC) feature is indeed the best way to go for your usecase.

Note that this feature is currently 'gated', so you will also need to contact AWS support to request access. See here for more info, then contact support here.

Refer to this documentation for creating signals in the signal catalog and decoder manifest on the cloud side: https://docs.aws.amazon.com/iot-fleetwise/latest/developerguide/network-agnostic-data-collection.html
and refer to this documentation for implementing the ingestion on the edge side: https://github.com/aws/aws-iot-fleetwise-edge/blob/main/docs/dev-guide/network-agnostic-dev-guide.md#sensor-data-collection

You're right that there isn't an example for using ingestSignalValueByName, however the guide above shows how to use ingestMultipleSignalValuesByName which is similar, but is instead for atomically ingesting multiple signal values at the same time with the same timestamp (for example signals contained within the same CAN frame.)

Please reach out if you have any further questions!
