CAN interframe time

Hello all,

I am using the CAN protocol to read and write data from the Flash memory of one STM32F446ZET6 board to the Flash memory of another STM32F446ZET6 board.

I have tried multiple baud rates. All working properly. However, I notice a 25 ms delay between every CAN frame, regardless of the baud rate.

Is this a default setting and/or is there a way to change this time delay?

Thanks!

Hello,

CAN peripheral embedded on STM32 is inline with the CAN protocol standard specified by ISO11898.

So it could be a delay introduced by the APIs overhead or some delay inserted in your code.
