the way of Bluetooth mesh ad hoc network, if the premise is that we do not know the deployment of each node in the network, can we obtain the distance of each node or the distance of two neighboring nodes by scanning the central node and broadcasting communication, and then use this to realize the topology diagram of all the nodes in the mesh ad hoc network? Checked a lot of materials are said that mesh to achieve the control of remote nodes, there is no relevant introduction whether it can perceive the distance of remote nodes, but also ask your little brothers with relevant experience to give advice. Thank you very much. Now it is known that the scanned equipment information can be obtained directly by scanning and the distance can be calculated by formula, but for the second hop and the third hop of mesh network. I don"t even know how to measure the distance.
