To: Bluez mailing list Content-Type: text/plain; charset="UTF-8" Sender: linux-bluetooth-owner@vger.kernel.org Precedence: bulk List-ID: X-Mailing-List: linux-bluetooth@vger.kernel.org Hi. I have a feature request that the negotiated ATT MTU should be exposed as a property in the org.bluez.Device1 interface. For some applications it's good to know or required how much data that can be written / read / notified in each packet, and it's not always desired or possible to use AcquireNotify / AcquireWrite. /Emil
