Tracking Missing!

[swzon]

Using TX Command got missing result, but the tool can tracking in the Track Application.

    if (_device == nullptr) return -1;
    ndiTX(_device, NDI_XFORMS_AND_STATUS);
    if (ndiGetError(_device) != NDI_OKAY) return -1;
    int num = _device->TxHandleCount;
    double transform[8] = { 0 };
    double w, x, y, z;
    for (int i = 0; i < num; i++)
    {
        if(ndiGetTXTransform(_device, i+1, transform) == NDI_OKAY)
        {
        }
        else
       {
       }
}

What error was returned?

[swzon]

No error, returned OKEY, but the tool state is MISSING.
When the Track Application started, we can got the tool infomation with this code.

[swzon]

got the reply from NDI like this: 0101MISSING
but the tool can track with Track Application in the same place.

Is this near the edge of the trackable volume?
