https://devzone.nordicsemi.com/f/nordic-q-a/72851/how-mesh-node-provising-itselfHi Guys， According to the MESH document, there are two ways of node provision: PB-ADV and PB-GATT (smart phone) . A provisioner provides the unprovisioned device with provisioning data that allows it to become a mesh node. the provisioning data includesen-USTelligent Community 13Wed, 17 Mar 2021 12:11:35 GMThttps://devzone.nordicsemi.com/thread/300378?ContentTypeID=1Wed, 17 Mar 2021 12:11:35 GMT137ad170-7792-4731-bb38-c0d22fbe4515:5185704b-424e-4240-ac4f-3f969b4c8b35Mttrinh<p>Hi,</p> <p>The idea with exporting the provisioning data to import into another phone or computer. It is also possible to import it into a mesh node acting as a gateway device, but we don&#39;t have built-in support for these exported files in the SDK so you have to implement this yourself.</p> [quote user=""]if a unprovisioned device holds <span style="color:rgba(255, 0, 0, 1);">all provisioning data</span>,can it&nbsp; provisioning itself?[/quote] <p>The exported data is not intended for self-provisioning. Using this to self-provision would be bad for security of the mesh network since whoever that has the exported file will be able to control the entire network, So importing this into a node isn&#39;t recommended.</p><div style="clear:both;"></div>
