https://devzone.nordicsemi.com/f/nordic-q-a/33979/mesh-access-layer-and-bluetooth-sigHello, is there a way to send messages via the mesh transport/access layer (not using client/server models) but still be Bluetooth SIG compliant? where can I find information about this? like which IDs we need to use, structure of a generic message? limitationsen-USTelligent Community 13Thu, 03 May 2018 07:41:57 GMThttps://devzone.nordicsemi.com/thread/130735?ContentTypeID=1Thu, 03 May 2018 07:41:57 GMT137ad170-7792-4731-bb38-c0d22fbe4515:2d595081-1295-4a39-a13d-a9a5ac5deaa2Bj&#248;rn Kvaale<p>I am not sure it is possible to send messages via the access layer in Bluetooth Mesh without using the client/server models. It says specifically in <a href="https://blog.bluetooth.com/the-fundamental-concepts-of-bluetooth-mesh-networking-part-1">this Bluetooth</a> blog that &quot;a Bluetooth Mesh Network communicates via a client-server architecture.&quot;</p> <p>For more information about Bluetooth SIG compliance, <a href="https://www.bluetooth.com/develop-with-bluetooth/qualification-listing">this link</a> might be helpful. In addition, the <a href="https://www.bluetooth.com/specifications/mesh-specifications">Bluetooth Mesh&nbsp;Profile Specification 1.0</a> could be useful to read.</p><div style="clear:both;"></div>
