Apart from increasing the baudrate, you can change the following parameters on the server side (in ISO-TP, it is the receiver that defines the communication parameters): - PCANTP_PARAM_SEPARATION_TIME: 0x00, set it to 0 to reduce the minimum time to wait between each fragmented frames. - PCANTP_PARA...

Hello Shail, I do not fully understand your question regarding delays.. But here is how ISO-TP communication is designed: - Client begins a segmented communication by sending a "First Frame". - Server receives the First Frame, the API notifies you that a message is pending (you have the information ...

Hello Shail, You're mixing a lot of things, before further development you should have a look at the documentation "UDS and ISO-TP Network Addressing Information" §4.3 page 339: It explains the default mapping configuration when you initialize a UDS channel. Please also check §4.3.2 page 342, to und...

You need to: 1. plug your 2 PCAN devices to your PC, 2. connect a PCAN-Term (120ohm termination adapter) to the first PCAN device, 3. connect a PCAN-Cable 1 to it then 4. add a PCAN-Term to the end of the cable 5. finally connect it to the other PCAN-device. Note that you can use a PCAN-Cable 2 that...

Hello, (1) PCUServer needs to be launched first as it listens to client requests. (2) (3) Two applications cannot use the same channel, see PCAN-UDS documentation, function UDS_Initialize page 259 : The Initialization process will fail if an application tries to initialize a PUDS‐Channel that has al...

Hello Shail, (1) Please refer to your ECU specifications, it is usually a call to UDS service RoutineControl (with a start command and the standardized "EraseMemory" routineId), but the parameters (a buffer of byte) are specific to your ECU: UDS_SvcRoutineControl(CanHandle, msgReq, PUDS_SVC_PARAM_RC...

Hello, UDS_WaitForServiceFunctional and UDS_WaitForService functions return PUDS_ERROR_CAN_ERROR when a network error occured. Originally the functions returned Ok, but users tend to forget to check the value of the member RESULT of their retrieved UDS message. As a result, when this error occur ple...

Hello, Status should be analyzed as hex for ease: - (uint)-2147476480 is 0x80001c00, - Flag 0x80000000 means this is a PCAN-Basic API status, - 0x01C00U is PCAN_ERROR_ILLCLIENT. PCUServer initializes a 2nd USB PEAK CAN device: PUDS_USBBUS2 (line 312), whereas PCUClient initializes the 1st USB PEAK C...

Dear Maxence,

The debug CAN information has indeed changed and the documentation is deprecated, thanks for pointing that out.
CAN information will be logged in the file "PCANBasic.log" in the working directory of the application.

Hello Maxence, 1. The automatic TesterPresent mechanism was only designed to keep alive non-default diagnostic session without interaction of the user. It is not possible to change the parameter of the service. 2. You want to check if an ECU is alive which is not the goal of the automatic TesterPres...
