Issue with RX buffer cleared when initializing/uninitializing other CAN channels (C# / PCAN-Basic)

[dat.bui@bklogy.com]

Hello,

I am building a C# application to flash an ECU via UDS.
My hardware setup includes 3 USB PeakCAN devices.

Problem description:

When I flash on CAN1, it works correctly.

However, if I call Initialize or Uninitialize on CAN2 or CAN3 during the flashing process, the RX buffer of CAN1 gets cleared, which causes the flashing to fail.

I already checked that the handles for the 3 CAN channels are different.

Questions:

Is there any known issue with the PCAN-Basic API where calling Initialize or Uninitialize on another channel clears the RX buffer of an already active channel?

Do I need to use a specific initialization sequence to avoid this problem?

Is there a recommended way to handle multiple USB PeakCAN devices in parallel without interfering with each other’s RX buffers?

Any advice or hints would be highly appreciated.

Thank you,
