Can Mesh Network actually be implemented to read temperature and humidity ?

[IOT Man]

Aim:- To read temperature and humidity over a mesh network and display it in an android application

Devices to be connected in Mesh :- 

• nRfF52840 Development Kit x2
• Thingy 52 x2

Questions regarding it :-

1. Can I Implemented the above mentioned aim with the devices I mentioned ? If Yes how (Please don't point to the repository examples already went through all of them no examples related to it are there?)
2. Does nRF52840 DK actually supports sensing temperature and displaying it over a Mesh network ? Is it still under the development stage?
3. Is it practically possible to implement the above task ?
4. How do I implement it there are no examples regarding it? What provisions are there like where I can learn how to do it ? As I am a beginner I can't create my own model for it ?
5. Is it possible to the above mentioned task using Nordic Devices ? If not shall I discard the idea of achieving the aim using above mentioned Devices?
6. Has anyone of your clients or developers like implemented to read the temperature and humidity of devices connected in the Mesh and displayed it on an application?

As there are no examples available and previous tickets I raised just pointed me to the same examples and asked me to create my own model

Please Revert back to me regarding it as if it is not possible using your devices or maybe there are still in development stage I should look for another option

If I am able to achieve above aim in nrf52840 DK I am willing to add Dongle in the network and do the same ? Is it possible

Hi again.

It is absolutely possible to create a Mesh network using nRF Devices for sensing temperature and forwarding this in a Mesh network.

We don't have any out of the box examples to match your requirement, so you will need to implement this yourself.
If you don't know how to write code or work with our SDK I suggest that you start by looking into this first.

We have a youtube tutorial on how to work with the nRF5 SDK and SES:
https://www.youtube.com/playlist?list=PLx_tBuQ_KSqGHmzdEL2GWEOeix-S5rgTV

We have demo examples for Mesh (both for Thingy:52 and nRF52840), but if you want specific functionality you will have to modify these examples to fit your requirements.

There are a sensor example, light switch example etc. Also there is a provisioning example for the Thingy that shows how to use the Mesh on a Thingy.
If you have specific problems when implementing your solution, we are more than happy to assist you.

Br,
Joakim

What is real-life application of the Mesh Network

[Joakim Jakobsen]

There is a blog post about how to use the nRF Mesh application here:

I know how to use it but how did I modify/libaries the are not present in the application for reading temperature sensor value and how do I provision it

Is your Mesh completely developed or is still in the baby development stage?

[Joakim Jakobsen]

No, our Mesh solution is not in "the baby development stage".

We have several examples that demostrate how a Mesh application and a network can look like. Both server and client examples with respective models. There's also a static provisioning example available if you don't have a phone etc. available to act as a provisioner.

Our nRF5 SDK for Mesh and it's examples can be used as a reference and a starting point for your own application.
It's not possible for us to create an example that will fit every single customers usecase and add them to the SDK. That is why we have a few selected examples, and our customers need to create their own applications based on their needs.

We also have our online documentation with extensive information about adding your own models, getting started with DFU, how to build and test the examples etc.
The nRF Mesh for mobile app is also available on github so that you can use that as a reference to create your own custom application.

If you need to create a custom application to work with a mobile app, you will have to develop that yourself. We can't write the example and the mobile app for you, but we are happy to assist if you have any trouble implementing this.

There is no problem using Nordic devices or SDK in order to achieve this. You can use one of the examples in the SDK as a reference and if you want, you can create your own custom model to transfer temperature data inside your Mesh network.
