Hello together,

I'm using PCAN-UDS to test the ECU UDS stack, but sometimes ECU does not response when request with multiple frame, like 2E F1 90 XX .. XX; then the trace was checked, it is found Waring occurs every time using PCAN-UDS to send request, no matter request with single frame or ...

Does the CCP message receive mechanism had influence on CAN_Read API?

Is any workaround to fix this issue?
