what do two checks mean on the signal messenger app

This arbitration is non-destructive and results in non-interrupted transmission of the highest priority message. PriorityĮvery message has a priority, so if two nodes try to send messages simultaneously, the one with the higher priority gets transmitted and the one with the lower priority gets postponed. Additional non-transmitting nodes can be added without modification to the network. This structure allows modifications to CAN networks with minimal impact. Each device can decide if a message is relevant or if it should be filtered. All devices on the network see all transmitted messages. Broadcast CommunicationĮach of the devices on the network has a CAN controller chip and is therefore intelligent. This decreases overall cost and weight in automobiles. An advantage to this is that electronic control units (ECUs) can have a single CAN interface rather than analog and digital inputs to every device in the system. CAN provides an inexpensive, durable network that helps multiple CAN devices communicate with one another.
