Unable to see characteristic information or read characteristics

[tslater]

First off, awesome job!
I got connected without too much trouble!

The only issue is that I don't seem to get any information on characteristics. I'm running on android.

You know what? I think it's returning my characteristics as services.

I've seen this too. The only way to get characteristics is to search for them by UUID. The "discoverAll" or "discover()" functions always return a zero-length array.

Additionally, standard GATT characteristics and services don't seem to be recognized by their short UUID's. Only 128-bit UUIDs work.

These problems appear to be Android only (I'm running Android 7.0), while iOS works fine.

In the linked issue a different solution is found: set the minimum sdk to 21 for android.
