Thank you. First anserw was right:) I didn't know that i need base. Now i have one so my setup is: One tracker with blue logo (2018) and on Base 2.0. But i still have a problem, because i don't have google (I don't need it in my work), and I'd like to use this one tracker. I connected everything, I have my tracker connected in app, and Lighthouse with green light, BUT it doesn't work. I had for few minutes my Base visible in application but pulsing and my tracker the same. It say, that it is connected, but not follow movement. I did youtube tutorial to disable using headset but still it doesn't work. Now my base have green light but i don't see it in application..
