Gardening application using mesh networking

[hilal]

We are making Gardening solution using BLE mesh network .

From nordic we found nRF52820 can support . We are looking for reference code for such application

Hi Aziz

You can have a look at our Mesh samples. I would how ever point out that Mesh might be a challenge due to the limited memory of the device, and I would recommend to switch to a device with more memory. The device also has limited peripherals as you can see here, so depending on the sensors you need it might be an issue. I would suggest moving to one of the devices you can see here. 

I would suggest trying to add the functionality you need and build a sample to get an idea of your memory requirements and then consider if you need to change device.  

For DFU over BLE in nRF Connect SDK, your application must use less than half the flash area. Basically, the flash must be divided into two equal-size slots, where the current application is in one slot and the update is downloaded to the other slot.  Serial DFU on the other hand, should work fine if configured to use only a single slot. (For serial DFU, the DFU process can be completely controlled from the bootloader, in which case you do not need the app to be running while you fetch the update.)

Dear Runar ,

Thanks for the feedback . In this application we switch on and off valves . There is no other sensor will be integrated.

The Max no of device in mesh could be like 20 no .

Then I would adopt one of the mentioned mesh samples. Try to build for the 52820 and see if you will have room for DFU. It will be borderline so I can't really say anything else then you have to try and see if there will be enough room for you.
