As we need to update some attributes value with timestamp, we need to use setPropertyVTQ.
This doesnt work:
valueCAN = twPrimitive_CreateFromString("PPLOG_TEST", TRUE);
twApi_SetSubscribedPropertyVTQ(thingName, "vehicleName", valueCAN, twGetSystemTime(TRUE), "GOOD", TRUE, TRUE);
twApi_PushSubscribedProperties(thingName, TRUE);
See below the different tries we did, we were only able to push standard properties ( without the timestamp info).
Thanks for helping
