S130 stack : app acts as GATT client and serverhttps://devzone.nordicsemi.com/f/nordic-q-a/7339/s130-stack-app-acts-as-gatt-client-and-serverHi, I need to implement an application who acts like a GATT client and gets notification from a GATT Server (on smartphone) and then sends the information to a GATT Client acting as GATT server. I think that it could be possible using SoftDevice S130en-USTelligent Community 13Fri, 29 May 2015 12:25:53 GMTRE: S130 stack : app acts as GATT client and serverhttps://devzone.nordicsemi.com/thread/25989?ContentTypeID=1Fri, 29 May 2015 12:25:53 GMT137ad170-7792-4731-bb38-c0d22fbe4515:53b0ba93-129e-4578-9dcc-31def123ccb6Ulrich Myhre<p>Hi Paolo,</p> <p>This is a common misconception, but GATT client and server is role-agnostic. All of our BLE SoftDevices come with both GATT client and server support, regardless of the the link layer roles it supports.</p> <p>Some smart phones only implement the central role, which requires you to use a peripheral SoftDevice like S110 (peripheral only), S120 2.0 (both roles, choose during softdevice initialization) or S130 (both central and peripheral simultaneously).</p><div style="clear:both;"></div>
