Re: What does mean "GattServices is nil" ?

Here's an interesting bit, I've tried with Chromebook Pixel 2013 and
Chromebook Pixel 2015 (different chipsets) and the results are
differents

Chromebook Pixel 2013 fails to get GATT Services:

Chromebook Pixel 2015 can discover all of them: http://pastebin.com/raw/z5vr0B3P

Does that make some kind of sense?

I didn't have a chance to try your patches sadly.
Feel free to push them as it will still be valuable for sure.

It turns out it was the cache malfunctioning, it does clear the cache
properly before storing the services when it changed so you would end
up with new and old services which obviously does not work as the
ranges tend to overlap.

Have you tried my patches? I will probably push them today if you don't object.
