Bootloader nRF52

[Arepa]

Hi all,

I am trying to "add" the DFU bootloader to my application and I have some questions regarding it:

my thought are:

1. add to DFU bootloader example code, part of my code adding the BLE capitability

-my code will run normally until the button is pressed to jump to the bootloader and perform the DFU

2. add the DFU service to my current project and add the device manager, and more required libraries.

which option is most viable?

Update 03/06/17:

Softdevice $132

SDK 12.2

How can I swith from my aplication to the bootloader?

Thanks

Hi Arepa,

Yes you can do that also. This requires you to modify the bootloader. The reason I suggested you to follow what we did in SDK v12 is for the compatibility with the future bootloader. But if you are OK with modifying the bootloader, then what you do is totally fine.

You should consider Option 1 only when you want to do background DFU, where you device functional normally when you are receiving DFU. But this requires lots of change in the bootloader and on how to integrate it with your application.

Hello

how to do dfu in background? For this option the dfu device has to be there all time while the application is normally running...

Thanks in advance
