The guide in my colleague's "Add DFU support guide" that I linked to have links to a GitHub repo with modified versions of the LBS samples that allow for DFU over BLE for example. I'd strongly recommend reading through the guide to see what changes are necessary in your BLE project to achieve this.

Best regards,

Simon

Hi Simon, I have checked those even I have implemented one DFU process for one of my devices. I want to know specifically, if I want to update the firmware of my peripheral device from sending the data using central device, what can I use ?. Would you please recommend me any specific library or example code which I can follow?

As Susheel said I'd recommend checking out the DFU libraries. We also have a guide on how to add DFU support to your application in the nRF Connect SDK available here.

Best regards,

Simon

Thanks, I have checked the DevAcademy, but I did not get any response for DFU process, how would I do that?

For what you're describing I would recommend a central <-> peripheral topology, and use the Bluetooth LE protocol. If you're new to the nRF Connect SDK I'd recommend checking out our DevAcademy, that has courses on nRF Connect SDK fundamentals, BLE fundamentals +++.

Best regards,

Hi, thanks for responding , I just want to confirm like what protocol or network topology I should follow like Mesh or Central peripheral will work?

Yes I understand that and I know this but I have updated the firmware using the Nrf connect Mobile app , to my device , I want to know what code I should use on my master device to update(DFU) my slave device

There are plenty of BLE samples in our samples that fit your requirement here.

[quote userid="120418" url="~/f/nordic-q-a/105180/need-suggestion-for-communication-between-two-nrf5840-board-wirelessly-over-ble"]Send and receive bulk data (~1Kb) from one Nrf board to another Nrf board[/quote]

Throughput sample has been designed to transfer chunk of data as fast as possible wirelessly through BLE.

Before that, I strongly recommend you to look at this getting started guide.
