Hi,
I have a project that is comunication between nRF and Smartphone via BLE and using libuartes to comunicate with 2 another devices via 2Uarts.
Now I need to combine 2 examples into 1 project. How many stepI have to do ?
I have compared 2 sdk_config.h of 2 examples. there are some differences in 2 sdk_config.h. I think just merge them into one file
What about another files? What I need to combine them and work in 1 project step by step?
Hope your reply soon. Thank you
Best regard,
Hi Edvin,
Thanks for your reply. I understand flow you suggested but I stuck in step how to include header file ?
In Project Explorer window I just find .c file.
step1 : added the links to the folder which contain .c files in Preferences -> General -> Processors > User include directories
step2 : then I added .c file by right clicking => add existing file.
And I don't know where contain header file (.h file) and how to add them ?
Addititon, How to add Dependencies and Output Files in .c file ? When I add nrfx_ppi.c I didn't find them like nrfx_gpioe.c, nrfx_clock.c.... which are already in ble_app_uart example 
Hi Edvin,
Thanks for your reply.
Here is all steps I did
step 1 : added the links to the folder which contain .c files in Preferences -> General -> Processors > User include directories
step 2 : then I added .c file by right clicking => add existing file.
step 3: compare sdk_config.h files of 2 examples and merge them all
step 4: compare include files in top of main.c of each example and merge them all
then I buid project and got this errors
