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.
