Thanks Rick. Mine has a firmware 2.x so they do not even send beacon so it will not be detected for sure. The GC100 by default have static IP so I have entered it, plugged into serial 1, prayed, pressed a button but it did not work.

If someone managed to make this work, please let me know, thank you.
