I can now receive UDS responses from my ECU!!! Many thanks. I had set the priority field to 7 as the priority field is set to 7 our project CAN messages. I thought I needed to set this. However it seems I did not need it set at all.

Hi, I have set N_AI.PROTOCOL to PUDS_PROTOCOL_ISO_15765_2_29B_NORMAL but still not working.

UDS API version is: 1.3.0.25
PCAN-ISO API version is:2.0.1.82

I using 64 bit version of DLLs.

I have attached the PCAN trace of the ECU responding to UDS request

Kind Regards

Thanks, I have not set it to 0xF9 but still no response.. I not sure what else it could be now

Have I got the N_AI set correctly in the below code?


// Define Address
iBuffer = 0xF9;
Status = UDS_SetValue(Channel, PUDS_PARAM_SERVER_ADDRESS, &iBuffer, 1);
printf(" Set ServerAddress: %i (0x ...

The ECU address is 0x93 which I have set via PUDS_PARAM_SERVER_ADDRESS

I have defined the client address as 0xF9 using:

// Define Network Address Information used for all the tests
N_AI.SA = 0xF9;
N_AI.TA = 0x93;
N_AI.TA_TYPE = PUDS_ADDRESSING_PHYSICAL;
N_AI.RA = 0x00;
N_AI.PROTOCOL = PUDS ...

Thank you. I have tried this but still no uds response is reported.

Hi, many thanks for your reply. I am using that this version already. I have modified the PCUClient sample app (x64) to work with my setup. Perhaps I done something wrong. I can see the UDS requests from the client are correct and my ECU sends a reply (I can see it in PCAN-View). Below is the code I ...

Hi, I think I may have the same problem with receiving 29 bit IDs. My ECU is responding but the UDS API is reporting no data. Is there a beta version of the API that resolves this issue available? Many Thanks.
