can you tell the process of device firmware upgrade using BLE through SMP

[Dileep Kumar]

i tried the DFU through Zephyr SMP server sample- https://developer.nordicsemi.com/nRF_Connect_SDK/doc/2.1.0/zephyr/samples/subsys/mgmt/mcumgr/smp_svr/README.html,

But i need to work with  two different sample images working through SMP server using mcumgr. if i trying one image with smp and another image with blinky application,it is not working.please tell the process how to resolve this issue

Hi,

The blinky sample does not have DFU support by default. This needs to added. See e.g. this page on how it can be done:

 Add DFU support to your application
