Hello aymen
Hope you are doing well!
CAN protocol is a way to communicate with the CAN bus (Controller Area Network), find information about the CAN bus in the following link https://en.wikipedia.org/wiki/CAN_bus
We use CAN protocol to interact with CAN parameters in the vehicles where the CAN bus exists,
Therefore, We can't configure a device through CAN protocol, In another hand, we can do the configuration over the air by using FOTA web, Or by sending SMS/GPRS commands,
Thanks!
