Hello, I tested all 3 ideas, but its not work. Today I found the solution! After follow mce comands its work:
I don’t know which line was is but I think the first.
mcetool --enable-radio=bluetooth
mcetool --set-lpmui-triggering=from-pocket,hover-over it was for the Sneak Peek with the sensor on screen
mcetool --set-ps-mode=enabled
Now I can go in my car and BT will autoconnect again like X10II. I am happy…
