difficulty with DFU examples

[sharu102]

I am new to Nordic and i am using nRF52840 DK, - SDK 15.2.0 - s140.
I have written an application by modifying the Heart rate Monitor example. My program acquires and sends sensor data over BLE to a phone application. Now i would like to add DFU feature to this example. Can anyone give suggestions on how to add DFU to heart rate monitor example. This would help me modify my application code.

Thanks & Regards

Hi,

We do have Getting started with Nordic's Secure DFU bootloader, a step by step guide.

The DFU bootloader is separate from the application, and adding a DFU bootloader can be very easy depending on your requirements for how to enter DFU mode. "Pressing a button while resetting the device" enters DFU mode by default, in which case flashing the bootloader (and a bootloader settings page) is enough for DFU functionality. Another option, which requires adding a BLE service to the application itself, is what we call "buttonless DFU". With buttonless DFU you can trigger DFU mode from a connected BLE device.
