Hi,

We are using nrf51422 in our project and SDK we are using is 12.3 and soft device is S130. In our project we need Bluetooth device should be connected to upto 3 devices so, we are tring the example program  ble_app_multirole so when i compiled this program i got this error "..\..\..\..\..\..\..\components\libraries\ecc\ecc.c(56): error:  #5: cannot open source input file "uECC.h": No such file or directory".

I also read the link to attach the micro ecc library file https://infocenter.nordicsemi.com/index.jsp?topic=%2Fstruct_sdk%2Fstruct%2Fsdk_nrf5_latest.html&cp=5_0file:///C:/Users/Admin/AppData/Local/Temp/Rar$EXa5692.47559/nrf5/getting_started_precompiled.html

so what i have done is i copied the uecc.h  file and attached into the specific folder

• InstallFolder\external\micro-ecc\nrf52_keil\armgcc

After attaching header also still i am getting this error

plz tell me how to resolve this problem.

So have you checked that the file does actually exist at all ?

If it does exist, is it in a location where the tools are configured to find it?

You haven't said what tools you're using, or what platform they're running on. If you're on Linux, remember that it is case-sensitive...

On understanding & setting up Include Paths:

Thanks for the reply.

i am using keil5  and running on windows platform.I think i have not added into the included path.can you plz tell me how to include the file into the path.Below i have attached the file

See the post I linked.

Note that setting up the Include Paths is not specific to Nordic - you do it exactly the same way that you would with any Keil project. So the standard Keil documentation & examples apply.
