What happens when you use our example App? https://github.com/mbientlab/MetaWear-Tutorial-Android
Do those work for you and whats the difference between your App and our Apps?

I clone the freefall app from git and run it on my android phone, it still has a connection problem.

and I believe that error comes from line 121

But if I use the MetaWear app (download from play store), this sensor works

can u solve it ???
