Hello,

If I configure library by UDS and use UDSApi.Read I can not read timestamp, but if I configure library by UDS and CanTpApi.Read function for read message I can read timestamp but I receive also a UDS message not only UUDT like in the previuos case.
So is possible in UDS library with UDSApi.Read to get timestamp? If no, is possible to use CanTpApi.Read and filter the message for UDS?

Thanks
Cappo

unfortunately not. Our UDS API doesn't return any timestamp. This is planed to be enhanced in a future version.

No, please note that UDS API is using PCAN-ISO-TP for communication. If you use both at the same channel and you read messages with ISO-TP, those messages will not be available anymore for UDS, causing in this way communication problems.

Okay, thanks but can I open a new channel on the same usb hardware?

Best regards

Hello,

if you have a hardware with more than one channel, yes (e.g. PCAN-USB Pro FD). For instance, you can use PCAN-Basic for CAN communication at channel 1, and PCAN-UDS for UDS communication at channel 2.

Okay thanks, so with PCAN-USB FD I can not do it.

Thanks

Hello,

no. You need either a multi-channel device, or two one-channel devices.
