I am using multiple dash devices to connect to the cloud for a project. I am using the router to send the data to a custom end point. At the end point I want to be able to clearly identify which peice of hardware (not SIM card) is sending the data. What is the most bandwidth friendly field to use for this?
I was using the Dash.serialNumber() but this is a pretty large number to send every message. Is the device id included in the message header unique per piece of manufactured dash hardware? What generates that number?
@Reuben, Is the device.id unique for each device? What assigns that value to the message, the modem, the system MCU. Is it programmed to the device in the factory? Is it assigned by the network?
