Re: What does mean "GattServices is nil" ?

I've given another try with latest master branch which contains your
"fix not clearing database after discovery" patch
(7664e160d8fe69e1ce6b48b6de5b3d3eb4db0d13) and I still don't have any
luck to get connected ;(

Hi François,

Actually this is caused by the following:

bluetoothd[6917]: Unable to register GATT service with handle 0x0012
for device F1:6F:DE:EC:F1:D6
bluetoothd[6917]: Unable to register GATT service with handle 0x0016
for device F1:6F:DE:EC:F1:D6
bluetoothd[6917]: Unable to register GATT service with handle 0x0019
for device F1:6F:DE:EC:F1:D6

Perhaps you forgot to enable the experimental flags (-E), anyway the
patch Ive mentioned is not yet pushed, I thought you would be able to
pick it for the mailing list.

After updating to your last patch
(http://git.kernel.org/cgit/bluetooth/bluez.git/commit/?id=d205d58b285542f845d59cab24793de7c12f4aca),
here's what I'm seeing now: http://pastebin.com/raw/4CXw36A5
As you can see, list-attributes doesn't list all attributes anymore ;)

And here's the diff which shows that more services are discovered
somehow: https://www.diffchecker.com/m20m9ga1

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:
http://pastebin.com/raw/gsi63kWg

Perhaps something else is affecting that, do you have the bluetoothd logs?

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.
