I am trying to understand the CAN network management of AUTOSAR. I am trying to sleep the ECU if there are no CAN message received during IGN cycle. I am blocking the CAN transmission and reception during this stage. Now suppose AUTOSAR NM message is received, i want to make the ECU to wakeup and need to make CAN to be full active. I have gone through the basic Autosar Network management understanding.
As per my understanding
If communication on the bus is needed i.e. requested, NM messages are sent out. If no communication is needed i.e. released, sending of NM messages is stopped.
When the Autosar NM state is "Ready Sleep state" or "Repeat Message State", I am waking up the CAN. I would like to know, this is a good approach.
