CAN LOOPBACK NUCLEO-L432KC DOSEN'T WORK

[GGGG_72]

Hello everyone,

I try to check the LOOPBACK mode on the NUCLEO-L432KC board, but doesn't work. The CAN frame transmitted is correct, but I don't receive anything. I'm checking the TX frame output correctly with an oscilloscope.

The code is very simple, but I suppose that has a bug (attached), ...could anyone help me?

SOLVED, ...it seems that it did not wait for the Tx frame to give me an ok (transmitted frame), ...and neither did it help debugging the STM32CubeIDE.
