Merging two or more examples

[Pero Krivic]

Hello

I am getting started on nRF SDK and I went through all the examples (at least those I'm interested about) successfully. 

Now, I need to merge couple of examples together. For simplicity let's say I'm merging an uart example into the twi_scanner one.

What I did, was

• to compare "Options" of two projects, and added missing include paths. For this example, I added /libraries/uart and /libraries/uart paths into the twi example
• Added required #includes, in my case these were #include "app_uart.h" and #include "nrf_uart.h"
• I've checked sdk_config.h and found that UART was enabled.

And it wasn't enough. For some reason linker fails, and complains it cant find references to any app_uart functions. Funny, since "Go to definitions" finds the file easily. 

So what am I missing? What else should be done?

P.S. I have already searched for help in the DevZone, and found useful threads like this one, but all the links in it are outdated and not working anymore.

Hello Karl, 

for some reason DevZone form doesnt allow me to reply to your latest comment, I'm writing here to say that I consider the matter solved and to thank you for your valuable time and effort to help me out. The initial issue has been solved by adding the .c file as you explained. Further issues have been solved by looking after the NRF_LOG backend.

Have a nice day
