https://devzone.nordicsemi.com/f/nordic-q-a/35525/add-provisioner-to-client-in-mesh-2-0-1Hi, As showed in the code, I masked &quot; else if (m_nw_state.provisioned_devices == 0) &quot;, then it reported &quot;NRF_ERROR_NOT_SUPPORTED&quot;. Can you tell me how should I do, thank you.en-USTelligent Community 13Tue, 19 Jun 2018 08:07:05 GMThttps://devzone.nordicsemi.com/thread/136667?ContentTypeID=1Tue, 19 Jun 2018 08:07:05 GMT137ad170-7792-4731-bb38-c0d22fbe4515:5b30c7b6-c0bf-40f7-ad52-faa3b6086494Bj&#248;rn Kvaale<p>Take a look at line 114 in provisioner_helper.c. This is where you receive the error:</p> <p><pre class="ui-code" data-mode="text"> ERROR_CHECK(nrf_mesh_prov_provision(&amp;m_prov_ctx, p_uuid, &amp;prov_data, NRF_MESH_PROV_BEARER_ADV));</pre></p> <p>Then, you could work your way backwards to see why this error is occurring.</p><div style="clear:both;"></div>
