Hello,

We will have an internal release candidate in two weeks, it will include support to PassThru 04.04 and 05.00.
The official release should follow quickly. We will update this thread to let you know.

Hello David,

The field in cantp_mapping is can_tx_dlc: the value must be a valid DLC (and not a length), so you should change your value from 64 to 0x0F.

Hello David, In your application, can you globally enable debug message by calling function CANTP_SetValue_2016 with PCANTP_PARAMETER_DEBUG before any initialization? Here is a C++ sample: uint8_t buf; // set debug mode buf = PCANTP_VALUE_PARAMETER_ON; sts = CANTP_SetValue_2016(PCANTP_HANDLE_NONEBUS...

Hello, I was merely suggesting beta to speed up testing and validate the fix on your side, no worries. Something happens to the PCAN J2534 DLL where even if I clear it and reset everything, I do not get any data back anymore from the J2534 DLL until I power cycle the interface. While in this state, ...

Hello, Thank you for your feedback, we have indeed internally reported and already fixed an issue related to a missing flag ISO15765_ADDR_TYPE for Rx messages. It will be included in the next release, you can contact support [at] peak-system.com if you'd like to subscribe to beta testing. We are in ...

Glad to hear that! For completeness and as knowledge base, here is an example of how one could send a UDS request with a 64 bytes single CAN FD frame (using UUDT): // Initialize channel const String BITRATE = "f_clock_mhz=80, nom_brp=1, nom_tseg1=127, nom_tseg2=32, nom_sjw=32, data_brp=2, data_tseg1...

The issue I described is only valid for ISO-TP single frame. ISO-TP segmented messages have by definition a data length bigger than the configured TX_DL, so the segmentd frames will use the dlc you set (apart from the last Consecutive frame which will adapt the dlc to fit the remaining data). So, yo...

You can change the can data padding value to 0x00 with the parameter PUDS_PARAMETER_CAN_PADDING_VALUE . You will then send a UDS request with the following 8 bytes data: 02 10 03 00 00 00 00 00. However you will NOT be able to send a UDS request with an actual UDS data size of 2 in a CAN FD frame wi...

Hello, "can_tx_dlc" is a parameter that allows you to configure the transmit data link layer data length (TX_DL) as defined in ISO 15765. But be careful as TX_DL only configures the maximum usable payload length of the data link layer. This means that UDS requests will actually use the smallest dlc ...

If you are using PUDS_PROTOCOL_ISO_15765_2_29B, you don't have to configure extra mappings: it is handled automatically by the API as the CAN IDs used to communicate are standardized. 1) Is it require to use PUDS_PARAM_MAPPING_REMOVE to remove when we are using PUDS_PROTOCOL_ISO_15765_2_29B? No 2) I...
