undefined reference to ble_conn_params_init()

[DeveloperZ]

Hello,

I was trying to implement the proxy profile into the Enocean switch example to try if the friend node for the switch can be provisioned using the Mobile App. 
I encountered the error reading "undefined reference to ble_conn_params_init"

I included the file in the project, also included the path to the folder containing the file but this compilation error isn't being removed.

What might be the reason?

Thank you.

I think the fact that there are no numbers in the 'Code' and 'Data' columns indicates that the file has not been built?

Try a full rebuild of the Project ...

I have been trying to rebuild it for numerous times but there was no change in the errors.

Hi.

I included the file in the project, also included the path to the folder containing the file but this compilation error isn't being removed.

 I see you have included the .c file, but have you included the header file aswell? #include "ble_conn_params.h"

Again, the fact that the 'Code' and 'Data' columns are empty shows that it is not being built.

Have you done a full rebuild - not just a build ?

Have you tried 'Clean' before 'Rebuild' ?

What if you compile just that file on its own ?

Have you looked inside the file to see if it is all being disabled by some #if ... ?

Your screenshot shows that you have other warnings. Are there also other errors? 

As always, fix the earlier errors & warning first.
