Hello,

I am facing the following issue with CAN Frame Transmission:-

- Data is properly filled in Message Buffer, but the code and time stamp is not changing and it keeps on sending data on CAN Bus and after some time bus get off.

- if Tx data is (0x55,0x55,0x55,0x55,0x55,0x55,0x55,0x55) or (0x55,0xAA,0x55,0xAA,0x55,0xAA,0x55,0xAA) the data is getting properly transmitted without any error.

I am not able to find the solution , please help me for this issue.

Thanks,

Regards,

Aditya

Hi,

Do you have another instance on the bus that acknowledges the message? The message needs to be acknowledged, otherwise it will be resent immediately.

Regards,

Daniel
