Hello
I need to integrate MESH DFU Example to Light_switch Example, I took part of the code from DFU example and added his to light_switch example main.c.
The first time the update is successful.
I increase the value --application-version and generate a new package.
I start to send an update, my nrf52840-DK with the serial starts to send, in the console percentages grow, but my DK without the serial does not react with LEDs in any way, as it happens when the update is in progress for the first time.
What am I doing wrong, what is missing?
