AWS IoT FleetWise OBD - github's demo.sh

0

Hello AWS people I would like to collect OBD data using <campaign-obd-heartbeat.json> in IoT FleetWise github. So I ran demo.sh with the following command.

$ ./demo.sh --vehicle-name vehicle-obd --campaign-file campaign-obd-heartbeat.json --region eu-central-1 --enable-s3-upload

I checked Timestream and S3 but I saw that no data was saved. My cansim@0.service log is as follows. ubuntu@ip-172-31-14-122:~/dist$ sudo journalctl -fu cansim@0.service --output=cat 2024-03-12 10:55:34.092813 Set THROTTLE_POSITION to 300 2024-03-12 10:55:34.092820 Set ECM_DTC1 to True 2024-03-12 10:55:39.097906 Set EngineTorque to 700 2024-03-12 10:55:39.598516 Set BrakePedalPressure to 1400 2024-03-12 10:55:39.598552 Set ENGINE_SPEED to 1800 2024-03-12 10:55:39.598560 Set VEHICLE_SPEED to 80 2024-03-12 10:55:39.598564 Set FUEL_TANK_LEVEL to 92 2024-03-12 10:55:39.598568 Set AMBIENT_AIR_TEMPERATURE to 28 2024-03-12 10:55:39.598572 Set ENGINE_COOLANT_TEMPERATURE to 88 2024-03-12 10:55:39.598576 Set THROTTLE_POSITION to 0

My fwe@0.service log is as follows.. The trigger for Campaign: arn:aws:iotfleetwise:eu-central-1:799856212300:campaign/vehicle-obd-80cbf4b8-campaign activated eventID: 1242325868 but no data is available to ingest

Please help me. I'm always indebted to you.

It seems the data is not being saved to S3 or Timestream as expected when running the demo.sh script.

  • Verify the IAM role used has the necessary permissions to write to S3 and Timestream in the specified region.
  • Check that the S3 bucket and Timestream database specified in the campaign file exist and the region matches where the script is run.
  • Review the logs for any errors when the SDK attempts to write to S3 or Timestream. Invalid credentials, missing resources etc could cause failures.
  • As a test, try saving a simple test object/record manually using the AWS CLI or SDK to check connectivity to the resources.
aws s3 cp test.txt s3://bucket/path/
aws timestream write-records --database-name db --records file://records.json
  • Compare the data format and names used in the script versus what Timestream and S3 expect. Make sure fields line up properly.

    Thank you for your kind answer! I used <campaign-break-event.json> collection rule to create and deploy e a campaign to save to s3 together. However, I found that [Vehicle.ECM.DemoEngineTorque] and [Vehicle.ABS.DemoBrakePedalPressure] data were saved really well in s3! Also, when I checked the IAM credentials, they were all authorized as AdministratorAccess! What did I miss? I guess OBD data is a problem. Is there any other log to see OBD data occurring other than cansim@0.service? I would like to know the answer! Thank you always!

    Thank you. After troubleshooting, I had to modify some variable values in the config.json file from 0 to 1. The variable values to change are as follows: obdInterface:pidRequestIntervalSeconds or obdInterface:dtcRequestIntervalSeconds. Thank you for your kind reply.
