• Which the release of FS2020 we see an explosition of activity on the forun and of course we are very happy to see this. But having all questions about FS2020 in one forum becomes a bit messy. So therefore we would like to ask you all to use the following guidelines when posting your questions:

    • Tag FS2020 specific questions with the MSFS2020 tag.
    • Questions about making 3D assets can be posted in the 3D asset design forum. Either post them in the subforum of the modelling tool you use or in the general forum if they are general.
    • Questions about aircraft design can be posted in the Aircraft design forum
    • Questions about airport design can be posted in the FS2020 airport design forum. Once airport development tools have been updated for FS2020 you can post tool speciifc questions in the subforums of those tools as well of course.
    • Questions about terrain design can be posted in the FS2020 terrain design forum.
    • Questions about SimConnect can be posted in the SimConnect forum.

    Any other question that is not specific to an aspect of development or tool can be posted in the General chat forum.

    By following these guidelines we make sure that the forums remain easy to read for everybody and also that the right people can find your post to answer it.

MSFS20 A32NX Custom data read

Hi,
I am able to read/write to default and custom events using simconnect, but as far as data is concerned I can only read and write to default data, not custom simvars.

Specifically I am trying to read if TRK/FPA mode is active on the Flybywire A32NX, with no success up to now. I am posting the relevant part of the code below if anyone can spot the issue (which I guess it must be very obvious to many of you :)) and help me, much appreciated. (Code builds and runs ok but value of fcuTrkFpaModeActive is always 0).

Thanks in advance

---------------------------------------------------------------------------------------------------
enum ClientData
{
LOCAL_VARIABLES,
};

enum DATA_DEFINE_ID0
{
DEFINITION_A32NX_LOCAL_VARIABLES,
};

enum DATA_REQUEST_ID0
{
REQUEST_A32NX_LOCAL_VARIABLES,
};

struct ClientDataLocalVariables
{
double fcuTrkFpaModeActive;
};

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

case SIMCONNECT_RECV_ID_CLIENT_DATA:
{
SIMCONNECT_RECV_CLIENT_DATA* pObjData = (SIMCONNECT_RECV_CLIENT_DATA*)pData;

switch (pObjData->dwRequestID)
{
case REQUEST_A32NX_LOCAL_VARIABLES:

ClientDataLocalVariables* pCDLV = (ClientDataLocalVariables*)&pObjData->dwData;

double TrkMode = pCDLV->fcuTrkFpaModeActive;

break;
}

break;
}

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

hr = SimConnect_MapClientDataNameToID(hSimConnect, "A32NX_CLIENT_DATA_LOCAL_VARIABLES", ClientData::LOCAL_VARIABLES);

hr &= SimConnect_CreateClientData(hSimConnect, ClientData::LOCAL_VARIABLES, sizeof(ClientDataLocalVariables), SIMCONNECT_CLIENT_DATA_REQUEST_FLAG_DEFAULT);

hr &= SimConnect_AddToClientDataDefinition(hSimConnect, DEFINITION_A32NX_LOCAL_VARIABLES, SIMCONNECT_CLIENTDATAOFFSET_AUTO, sizeof(ClientDataLocalVariables));

hr &= SimConnect_RequestClientData(hSimConnect, ClientData::LOCAL_VARIABLES, REQUEST_A32NX_LOCAL_VARIABLES, DEFINITION_A32NX_LOCAL_VARIABLES, SIMCONNECT_CLIENT_DATA_PERIOD_SECOND, SIMCONNECT_CLIENT_DATA_REQUEST_FLAG_DEFAULT);
