Secure Bootloader OTA from a custom BLE central device

[@nj@ly]

Hi, I am using nRF52 device with S132 v3.0.0 and SDK 12.2.0. I have one central device and peripheral device communicating each other. The peripheral device is running the secure bootloader and I want to OTA this peripheral from my custom nRf52 central device. I have tried doing using nRFToolbox App and it is working fine. Is there any documentation describing the events happening during OTA. We are using a .zip file containing the application and a key file for OTA using nRFToolbox. So how to transfer both these files from a custom nRF52 device. Any one had tried it before?

Waiting for a reply

Hi,

This document describe how OTA DFU is performed and the command set to be used.

You can also follow the DFU library for nRFToolbox as a reference. You can have a look at the source code here.
