Hello,

could you please tell us which PCAN hardware are you using?

Hello,

Am using PCAN-USB with windows 10 PC

Hello,

do you mean, that you have only one PCAN-USB (one channel) connected to your PC? If it is so, then the problem is clear. You need one physical channel for each connection.

Hello,

Thanks for reply.

Actually its PCAN-USB FD. So if I understand correctly, we need to connect, two PCAN-USB FD, one for Transmission and other for Reception. Please confirm.

Hello again,

Yes. As said before, you need one physical channel per connection. Our fee free APIs do not allow connecting the same physical channel more than once at the same time.

Please note that you can use different PCAN hardware, for instance, one PCAN-USB FD and one PCAN-PCIe card.
