Please have a look at section 4.2.1.1 in the Mesh spec v1.0.1</p> <p>You can find that we use&nbsp;<span>DEVICE_PRODUCT_ID</span><span>&nbsp;and&nbsp;DEVICE_VERSION_ID in&nbsp;config_composition_data_get() in composition_data.c&nbsp;<br /><br />2. I&#39;m not sure which settings page you are talking about.&nbsp;<br /></span></p> <p><span>3. I assume you are talking about advertising data for Proxy role&nbsp; ? It&#39;s not necessary to include such information. You may need to modify the adv_data_set() function in proxy.c to add your manufacturer&nbsp;data with the PID and VID in .</span></p><div style="clear:both;"></div>
