Hello @michael3, it would seem that you’re correct: the dTIR is not working with Labview EV3. The dTIR sensor should work with BrickPi3, NXT, and EV3Dev (not EV3-G, which is what most EV3 users use).
I am really sorry about this; we think that the EV3-G blocks stopped working with a firmware update that happened between now and 2014. We will be happy to offer a full refund, and we’ll make it more clear on the Amazon page and our web page that the sensor does not work with Labview. I’m sorry about the issue, and we’ll reimburse or replace for you.
