Custom UUID for SMP service

[Beldramma]

Hi, 

I am using NCS. 

I am using SMP service through BLE, and for security reason I would like to have a custom UUID for the BLE service.

UUID is defined in zephyr\include\zephyr\mgmt\mcumgr\transport\smp_bt.h.

Is there a way, without modifying zephyr repo, to have a custom UUID ?

I have created on app side, the same path : \include\zephyr\mgmt\mcumgr\transport\smp_bt.h and created a copy of smp_bt.h, with only a difference on UUID.

I think, by modifying CmakeLists.txt, or prj.conf, it is possible to indicate that this file should be taken instead of the one in zephyr. 

Can you help on that ?

Hi Benjamin,

I searched on my side too and did that too.

at first i had the same line as you in Cmakelists but my file was not taken in priority, so i changed it like that, and it worked.

target_include_directories(zephyr_interface BEFORE INTERFACE 
    ${CMAKE_CURRENT_SOURCE_DIR}/include)
