Hello,
at first, very nice library which works with socketcan. Good job!
I maybe found a problem with this library.
I am sending 2048 bytes of data to my developed ECU via UDS protocol from tester program which contains your python library.
After receiving first block of data from PEAK cable my ECU sent confirm frame back to tester in properly time, but the udsoncan library either wrote warning:
2024-04-04 13:31:03 [ERROR] UdsClient: [TimeoutException] : Did not receive response in time. P2 timeout time has expired (timeout=0.200 sec)

As you can see last row contain response from my unit and the response time from last message is is lower than P2 time.
Do you have any idea where should be a problem?
Can be that a problem with buffering inside PEAK cable?
Thank you very much for your response in advance and wish you good luck with projects like this.
