In the documentation of the nRF SDK for Mesh v4.1.0 is written: "The following figure demonstrates how the data packets flow between mesh nodes and their layers within the mesh stack structure." But there is no figure demonstrating the package flow. https://infocenter.nordicsemi.com/index.jsp?topic=%2Fcom.nordic.infocenter.meshsdk.v4.1.0%2Fmd_doc_user_guide_mesh_basic_architecture.html
