The new telemetry system uses a Raspberry Pi to collect CAN messages from the vehicle along with metrics such as GPS coordinates. We use Node-Red to collect this data and also send it to FRED’s Node-Red which will store our data in the cloud and allow us to pull data from InfluxDB which is hosted by FRED. We also have a DBC file that helps us translate what each CAN message-id and data mean.

Setup

The link below shows how to generate the DBC file used to translate all the CAN messages. It also shows how to set up AWS so our scripts will work.
