nRF52840 wireless mesh network set up

[Rorisang]

Hi, all. I am in need of serious help. I need to set up a wireless mesh network using the nRF52840 SoC. It must have 9 nodes and be capable of multi-hopping. I need to set up the mesh in a building with obstacles and  each nodes may need to relay packets to other nodes to help with the communications. I also need help with logging the latency and packet delivery ratios. Is it possible to detect the dynamic routing within the mesh?  I am only a beginner and i have done the examples successfully but i simply cannot do the mesh-it seems out of my league for now and so i need help. I have even gone through the You Tube videos but they have no code and mostly show only the 'blinky examples'. Please help. I tried  to contact other developers on the forum who wanted the same solutions but they have not responded and so i decided to contact the general community. Thank you in advance. 

P.S. I am new to this and so please be more plain in your explanations.

I assume you used the nRF5x SDK for Mesh ? You need to be specific with the question otherwise it is hard to help. . Get started with the nRF5x SDK for Mesh with the getting started section for Mesh.

Use the documentation and if you have questions, make the question specific and there will be help. It is easier to help if the questions are specific.

Hi, David. I hope i will be clearer now.

I am trying to set up a nine router/node wireless mesh network using the nRF52840 SoC. I am stuck in that i do not know how to program the chips so that they can connect to each other and communicate. I have downloaded the SDKs and can only do the easy 'blinky' examples. My knowledge is limited as i have a physics background.

I have read all the sections. I have 3 boards in front of me right now-all on. I want to replicate the mesh light switch example. I am using Segger. Whe i try to build the solution before programming the cleint, server and provisioner chips i get  the error :

did you unzip the zip file to a folder ? This looks like you have opened the zip file and are trying to compile it.

Added Edit:

Extract the zip file before attempting to compile it. On windows : Right click on the zip file and click on the "Extract all..." option.

Just keep it to yourself if you can't help me. I certainly did not need your very annoying reply. You may as well tell your friends about it and have a laugh 'Mr. Rocket Scientist'.  Is there a problem if someone if someone says "I want to be a car driver but i am still a learner driver?". Be careful about looking down on other people because you know so much. I will get to the stage you are at, no matter how long it takes me. I might never be as good as you but you were once like me-this i do not have to imagine. Have a lovely day.

My opening up about my background was meant to tell whoever is interested IN HELPING ME, my weaknesses not to intimidate anyone, in case you took it that way since you like imagining so much.

I extracted all the SDKs to the C drive. I somehow am missing the nrf_sdm.h file( error is : nrf_sdm.h: No such file or directory). I followed the instructions which say i must extract both the mesh and

nrf5_sdk_for_mesh &
nRF5_SDK_15.0.0_a53641a

files to the same folder. My problem seems to be this procedure.
