PEAK-System Forum

Hello,
I'm using your PCAN Basic API for more than a year with a PCAN USB.
I use the UDS protocol on top of it.
When I send a request (for example TesterPresent UDS function) and no one answers it on the CAN network, the request is sent in a loop for more than a hundred times.
Do you know why it behaves like this? And, is there a way to avoid this behavior?

Thanks in advance.
Best regards,

Romain Bouchaud

Using the PEAK-System UDS Protocoll is very complex. We need more information what exact you do - please:
