Custom data collection and sending to AWS cloud

[akashenji]

I am using the IWG26 device and have verified the completion of vehicle and campaign creation, as well as the GPS and CAN data collection. The server-side data collection verification still needs to be tested. Before proceeding, I would like to clarify the following queries:

1. In the campaign-obd-and-location-heartbeat.json sample file, the fields "Vehicle.CurrentLocation.Latitude" and "Vehicle.CurrentLocation.Longitude" refer to the iWaveGPS data being sent to the server?

2. I would like to collect additional custom data from the device and send it to the server once at the start of the application and some other data for every 30 seconds. Please guide me on how to implement these features in the AWS Edge application.

Hello @akashenji,

1. Yes, Vehicle.CurrentLocation.Latitude and Vehicle.CurrentLocation.Longitude refer to the iWaveGPS data being sent to the server. You can go through the iwave-g26-tutorial for more information.

2. To collect custom data from the device , you can implement custom data collection using the Network Agnostic Data Collection (NADC) feature of AWS IoT FleetWise. You can refer to this developer guide for more information. For collecting data at application start, you can define specific signals that are triggered when the campaign starts and for periodic data collection, you can create a campaign that collects the signals at the desired interval

I have created the signal catalogs and all the necessary features from the cloud side, but now I am unable to send the data to the mNamedSignalDataSource as a STRING data type. Is there any function available in the AWS Edge app to ingest string data?

Can you also explain how to use it?

You can take a look the Network Agnostic Data Collection (NADC) examples, which shows a few use cases: https://github.com/aws/aws-iot-fleetwise-edge/tree/v1.2.1/examples#examples-list including one what ingest a signal as string: https://github.com/aws/aws-iot-fleetwise-edge/blob/v1.2.1/examples/network_agnostic_data_collection/MyCounterDataSource.cpp#L52
