There are also regressions, though I believe we fixed most of those (I saw a lot of your patches fly by, thanks for those). I think I also have one patch that I need to rebase still. >>> Otherwise, that's where the API stands :) >> >> actually I would prefer if we get this upstream quicker. And that applies to GATT client and GATT server support. I was under the assumption that Luiz was working on this as well.

Even if you reviewed it within an hour of seeing the patches, it will still take me another 12-24 hours to see your response and address it. >> One small detail here. I hope we are clear that "service" in LE GATT means the server side and "profile" in LE GATT is actually the client.
