Lifght switch client example with DFU issue

[UdjinPr]

I use 3.10 mesh sd and 2 dk boards.

DFU example works fine, but when I try to implement dfu mode in ls example I can't achieve goal. DFU doesn't work. I follow the instruction of the dfu example, but Istead of the dfu hex file I use hex file from the ls client project with some correction and get no reaction after start of  dfu mode. At the very last I changed main.c in the ls client example from dfu project and result the same. I double checked sdk config and macros placement they are the same. 

I have no idea about it ).

and some important details: on master node(board which is used for transmission) is used original dfu example, and on the slave board I off serial driver, becouse it clashes with saadc.
