How do Mesh nodes return data?https://devzone.nordicsemi.com/f/nordic-q-a/25352/how-do-mesh-nodes-return-dataHi, Do you know how to make the nodes in the Mesh send back the data to the main device? For example, a node is a sensor that gets a new value and now needs to send the new value to the main device, and let the other nodes know that it has acquireden-USTelligent Community 13Thu, 21 Sep 2017 11:48:06 GMTRE: How do Mesh nodes return data?https://devzone.nordicsemi.com/thread/99915?ContentTypeID=1Thu, 21 Sep 2017 11:48:06 GMT137ad170-7792-4731-bb38-c0d22fbe4515:f76a3b4e-415f-4787-877a-135e87991766bjorn-spockeli<p>Hi Libo,</p> <p>the Bluetooth Mesh communicates using <strong>models</strong>, so you will have to create a custom sensor model client and server.</p> <p>The sensor node should act as the Sensor Model Sever, publishing the sensor data to other nodes that implement the Sensor Model Client, that subscribes to the sensor data. You can find a guide on how to create your own custom model <a href="https://infocenter.nordicsemi.com/topic/com.nordic.infocenter.meshsdk.v0.9.2/md_doc_getting_started_how_to_models.html?cp=4_1_0_3_6">here</a>.</p> <p>Best regards</p> <p>Bjørn</p><div style="clear:both;"></div>
