Set BAT_INDEX as uint16 in example code

[der-eismann]

This just cost me around 30 minutes because I couldn't figure out why the example code wasn't working, I always got this:

ERRO[0000] message at index 0: expected *uint16 got int : value does not match data type

And then even when I tried to pass a *uint16 as requested, I got

ERRO[0000] message at index 0: expected *uint16 got *uint16 : value does not match data type

so maybe the error message could use some improvements as well.

But most important is to set the value as uint16 and the example will work.

Thanks for your contribution, I know, the errors are very generic... but thats because the code is very generic and I didn't had the time to implement the proper error handling in a more user friendly way.

No problem, I'm happy that there's actually a usable library! Thanks for creating and sharing it 🙂
