https://devzone.nordicsemi.com/f/nordic-q-a/38769/preparing-light-switch-for-dfuHi, We are trying to have control on firmware update of our BLE mesh network. As a starting point I have ran the light-switch examples and DFU over mesh example. In light-switch examples we can create groups and control them. In the DFU mesh examplesen-USTelligent Community 13Mon, 24 Sep 2018 08:21:28 GMThttps://devzone.nordicsemi.com/thread/149948?ContentTypeID=1Mon, 24 Sep 2018 08:21:28 GMT137ad170-7792-4731-bb38-c0d22fbe4515:184a4b50-44d0-4fe9-8993-7f6ea3645c62Hung Bui<p>Hi Shohidur,&nbsp;</p> <p></p> <p>Currently we use application_id to do selective DFU update, you can read <a href="https://devzone.nordicsemi.com/f/nordic-q-a/38202/selective-dfu-over-mesh">here</a>.</p> <p></p> <p>Mesh DFU is independent from the normal Mesh operation so the grouping/subnet in the normal Mesh operation wouldn&#39;t apply when doing Mesh DFU. Mesh DFU is proprietary protocol&nbsp;from Nordic.&nbsp;</p> <p>To be able to do grouping dynamically (compare to the&nbsp;hardcoded application id) is to add a feature to change the application_id dynamically.&nbsp;You can implement it by adding a custom model to do the task.&nbsp;</p><div style="clear:both;"></div>
