Hello,

please share the first screenshot (both PCAN-Views) again, but showing their status bars .

Hi,

This is the output using the latest version of ISO-TP from your website.
Should there not be more bytes of data according to the size of HEAVY.DATA.SIZE.

Hi,

This is the full screenshot that includes the status of each PCAN USB.

Hello,

please note:

1. You are not using the latest version of the API, v3.2.0.
2. You are using a modified 06_isotp_segmented_read_write sample since the words "last bytes + [DATA]" are not used in the original code
3. The percent of message sent is going from 0% to 100%. This is not possible in the way this sample is configured.

Again, to check that it work as expected, you need to have two PCAN devices connected to each other, and well terminated. Compiling and starting the original 06_isotp_segmented_read_write example with this physical configuration should show the sending of a large message. Please use the latest version of the APIs. A well output looks like this:

Hi,

I have downloaded the latest version of the ISO-TP API from your website, but when I execute the application, the command prompt still shows v3.1. It's worth noting that the .dll files are still from the v3.1 packages. Could that be the cause to why I'm still seeing an older version despite running the most latest version of the application?

Hello again,

threre is something I forgot to check. Please use the PCAN-View to see the firmware version of the PCAN devices you are using (Tab "PCAN-USB"). There is a feature needed for ISO-TP to work that is not available in all firmware version. If your devices have the firmware version 2.8, then this is the cause of your problem.

To solve this, please downlaod and start the PEAK-Flash software, and follow the instructions to update your devices.

Hi,

Are these the latest firmware versions for this device?
Are the .dll files from version to version the same, (referring to my previous message)?

Also, as soon as I run the application, the status changes from OK to BUSHEAVY on both devices.

I have just checked the online package from our website. It is the right version, v3.2.0

1. Check that your browser is not giving you a cached file.
2. Check that you are copying the right dll file (64 vs 32 bit) into the right system folder (Windows/system32 vs Windows/SysWOW64 folder), or
3. Check that the dll file copied into your output folder matches the platform of your project (64 vs 32 bit)

Of course not, each release has its own file with own version. Current version is 3.2.0.

Then you have obviosly a physical problem. Bitrate doesn't match, wrong termination is being used, or similar. If you think your device is defect, please contact our support using support[at]peak-system.com. They may help you cheking the device

Hi,

Just to confirm, the 64-bit .dll should go into Sys32 and the 32-bit .dll should go in the SysWOW, right? I tried it the other way around and the application was throwing me errors.
