And that applies to GATT client and GATT server support. I was under the assumption that Luiz was working on this as well. So what can we do to make this go faster? Im doing the review as quick as I can, normally within 1-2 days, and Im even fixing things myself to try to speed up the process. > 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. The GATT server exposes a service and the profile explains how a GATT client uses it. That perhaps needs changes then, we start using GattService1 as client side API. > Regards > > Marcel > > -- > To unsubscribe from this list: send the line "unsubscribe linux-bluetooth" in > the body of a message to majordomo@xxxxxxxxxxxxxxx > More majordomo info at http://vger.kernel.org/majordomo-info.html -- Luiz Augusto von Dentz -- To unsubscribe from this list: send the line "unsubscribe linux-bluetooth" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
