You can start with this,
You have to integrate SMP_Server demo example in your current #BluetoothMesh project.
It will be tedious process, so my advice is to start with simple example.
For example, edit $zephyr/samples/subsys/mgmt/mcumgr/smp_svr so that it will blink LED1 on your board & flash it along with mcuboot as per link I have provided.
Then re-edit same smp_svr, so that it will blink LED2 on your board & now try to upgrade this using #DFU_OTA feature. This will help you lot to understand over all process.
is it possible to use the Nordic DFU feature in conjunction to Zephyr. I need to upgrade the nodes of a BT mesh network and it would be amazing if I could.
If it isn't, is there any alternative to that?
