We are using TJA1145 High-speed CAN transceiver for partial networking. The selective wakeup is configured. But it is observed that the transceiver wakeup do not happen with first frame. But on receiving the second frame the wakeup is successful.  Also if there is a significant delay between the first and second frame (two frames must be received within 1sec) also the transceiver do not wakeup. Could you please help us in this regard.
