mcumgr libraries being used in nRF Connect android app

[Ubaid_M]

Hi,

since The image management provided by mcumgr is based on the image format defined by MCUboot, so does "nRF Connect android app DFU mode" use mcumgr libraries in it's code to DFU a device through app..? 

Thanks,

Hello,

Yes, it does.

To clarify, it does both the new mcumgr which is used for NCS bootloaders (mcuboot), and it also supports the old bootloaders from nRF5 SDK. 

I know close to nothing about phone app development, but you can find the source code for the libraries here:

https://github.com/NordicSemiconductor/?q=Nrf+Connec&type=&language=

nRF connect for iOS/Android are not open source, but the DFU libraries used are open source. In addition, the app nRF Toolbox is open source, and it also uses the same DFU libraries as nRF Connect for iOS/Android, so you can use that as a reference on how to use it. All of these are linked in the github link above. 

BR,
Edvin
