Will get that tested.
Lidar sensor is now running in its own thread, and so are the ultrasonics 
(all in one thread because I poll them after each other with some time 
between to prevent pickup from each others pings.)
Will finally do a new test run tomorrow! finally looking more stable now.
I have to look into closing the threads when connection is broken, that 
isn't working ok now.
Have to reset the app (service) to make it work again after a connection 
lost.
But that's for next time ;)
