Date: Wed, 11 Feb 2015 19:17:44 -0800 Message-Id: <1423711064-7390-15-git-send-email-armansito@chromium.org> In-Reply-To: <1423711064-7390-1-git-send-email-armansito@chromium.org> References: <1423711064-7390-1-git-send-email-armansito@chromium.org> Sender: linux-bluetooth-owner@vger.kernel.org List-ID: Updated the GATT/ATT related TODO items: - Removed item about disconnect handling as this is already done via bt_att. - Long-term client caching is currently done in memory. Updated this to mean peristent. - GAttrib has already been turned into a shim around bt_att. Updated the related item to involve updating profiles only. - GATT client D-Bus API has been implemented. - Added item for missing portion of Service Changed support. - Added item for GATT related refactors discussed over IRC. - Added item for supporting the Includes property in GATT client. --- TODO | 54 ++++++++++++++++++++++++++++++------------------------ 1 file changed, 30 insertions(+), 24 deletions(-) diff --git a/TODO b/TODO index e489221..db80b95 100644 --- a/TODO +++ b/TODO @@ -136,41 +136,19 @@ ATT/GATT (new shared stack) Priority: Medium Complexity: C1 -- Introduce a handler interface to shared/gatt-client which can be used by the - upper layer to determine when the link has been disconnected or an ATT - protocol request times out. +- Persist client attribute cache across reboots.
