Hello Fabrice,

Thank you very much for the fast response!
Your suggestion helped a lot, and it works now as expected! I've had the feeling that I am only missing the solution by a little, however I did not see the full picture.

Thank you for your help,

Hi,

I am writing a wrapper DLL in C# for UDS services. One of the services which I plan to use is the "Write Data by Identifier" service. I need to use CAN FD protocol, with varying length of data to be written to certain ID-s. If I have no more than 64 data bytes to be sent, then I would like to ...

Hello Fabrice,

Yes, indeed, you were right, there was a mistake on my side. In fact I do not need to use the WDBI service, I just need to send the message as the data bytes listed.

If my understanding is correct, I could just use "UDS_Write" from UDS level, or "PCANBasic.Write" directly on PCAN ...

Hello Fabrice,

I have a similar situation, where I need to send a CAN frame with a 29 bit CAN ID of 0x18EF70C9, in an UDS service: Write Data By Identifier. with data content of: (0x54, 0x05, 0xFF, 0xFF, 0xFF, 0xFF, 0x42 0x00)

What I did in C# so far was:

Created a request structure:

Hello Keneth,

I can confirm, that the 32bit version of the RC of the fixed version of the PCAN-UDS DLL has the Write Data By Identifier service bug removed. The 64bit version I am currently unable to test myself.
I am still in the process of confirming if the "Init time delay" problem also ...

Hello Keneth,

Thank you for looking into and fixing it!
I will definitely write to the support channel about the RC version to try.
What do you think, when can we check for a release version that has this fix in it?

Thank you and Best Regards:

Hello Keneth,

Here are the details:

Downloaded PEAK-System_Driver-Setup.zip on the 3rd of June, 2019. Contained the file: PeakOemDrv.exe with file date of 6th of February, 2019. This installed the PCANBasic.dll in C:\Windows\System32\ with version: 4.3.2.161

I have downloaded on the same day (3rd ...

Hello Keneth,

Thank you again for the quick reply.

I went and copied the "old" version (Version: 1.2.1.18) of PCAN-UDS.dll next to my wrapper DLL.
I have left my wrapper code unchanged.
Now the wire capture of the 0x2E is correct (with known working DID of 0xF198):
10 09 2E F1 98 00 00 00

I have ...

Hello Keneth,

Thank you for the quick reply!

I am a little bit afraid to just updating each API to the latest version.

I have developed my wrapper DLL in "waves", meaning I have done some work last year, and since 9 months, nothing. In another project I have started to develop a new branch of my ...
