USB8506/2

Hello

For an application using C# and USB8506 component with the "nixnet.dll"

I have to send master request frame onto the lin bus and then read the slave response,

to make that i use the sequence bellow

-------------------------------------------------------------------------------------------------------------------------

nxCreateSession("database", "Cluster", "frame0,frame1", LIN0,nxMode_FrameOutStream, m_OutputSessionRef);
nxCreateSession("database", "Cluster", "frame0,frame1", LIN0,nxMode_FrameInStream, m_InputSessionRef);
nxWriteFrame(m_OutputSessionRef, l_OutputBuffer, 24, 0);
nxWriteState(m_OutputSessionRef, nxState_LINDiagnosticScheduleChange, sizeof(uint), nxLINDiagnosticSchedule_MasterReq);
nxWriteState(m_OutputSessionRef, nxState_LINDiagnosticScheduleChange, sizeof(uint), nxLINDiagnosticSchedule_SlaveResp);
nxReadFrame(m_InputSessionRef, l_InputBuffer, 24, 5.0, l_NumBytes);

nxWriteState(m_OutputSessionRef, nxState_LINDiagnosticScheduleChange, sizeof(uint),nxLINDiagnosticSchedule_NULL);
nxWriteState(m_InputSessionRef, nxState_LINDiagnosticScheduleChange, sizeof(uint), nxLINDiagnosticSchedule_NULL);

nxClear(m_OutputSessionRef);
nxClear(m_InputSessionRef);

-------------------------------------------------------------------------------------------------------------------------

When I start my application and "NI-MAX" together all is good

but if I stop "NI-MAX" I have no response (nxReadFrame end with error (Hex 0xBFF6300A)).

Where does this problem could come, do we have to use temporisation between the dll function....?
