Hi,

When I configured the USART to "smartcard with card clock" mode, it can receive the response with 2bit guard time from smart card, but can't receive the response with 1bit guard time.

Please advise why it can't receive the response with 1 bit guard time from smart card.

Thanks,

QiZhang

Hi @zqizh.1 ,

Normally both options are supported, listed in documentation as 0.5 and 1.5 stop bits communication.

USART1-3 should be normally capable. Try using CubeMX to generate the full correct configuration or refer to an example from cube package.
