Error when setting PCAN_TRACE_LOCATION for same folder multiple times

[PranavBodke]

Hello Team,

I am facing an issue while configuring the trace file location using PCAN-Basic API.

When I set TPCANParameter.PCAN_TRACE_LOCATION to a specific folder for the first time, it works correctly.
However, when I try to set the same folder again, the API returns an error.

Code snippet:

Code: Select all

ushort channelUsed = PCANBasic.PCAN_USBBUS1;
string tracesFolder = System.IO.Path.GetTempPath();
string fullPath;

fullPath = System.IO.Path.Combine(tracesFolder, "PCAN-Basic_Flashing");
System.IO.Directory.CreateDirectory(fullPath);

if (PCANBasic.Initialize(channelUsed, TPCANBaudrate.PCAN_BAUD_500K) == TPCANStatus.PCAN_ERROR_OK)
{
    if (PCANBasic.SetValue(
            channelUsed,
            TPCANParameter.PCAN_TRACE_LOCATION,
            fullPath,
            (uint)fullPath.Length) == TPCANStatus.PCAN_ERROR_OK)
    {
        Console.WriteLine("Trace location set successfully");
    }
    else
    {
        Console.WriteLine("Error while setting trace location");
    }
}

Observation:
- First time setting trace location → Success
- Setting same folder again → Error

Is PCAN_TRACE_LOCATION required to be set only before Initialize()?
Is Uninitialize() required before setting it again?

Any guidance would be appreciated.

Best regards,

Hi,

which version of the PCANBasic API and driver do you use?
