Undefined symbol from device manager

[helpme]

I encountered the following error while adding device manager to ble_uart_app in SDK_11 s130 using the hardware nrf51-DK. I'm using Keil compiler.

._build\nrf51422_xxac_s130.axf: Error: L6218E: Undefined symbol dm_init (referred from main.o). ._build\nrf51422_xxac_s130.axf: Error: L6218E: Undefined symbol dm_register (referred from main.o). Not enough information to list image symbols.

I have included device_manager.h in the PATHS. Using Keil, I did it by going to Menu->Flash->Configure Flash Tools ... -> Include Paths -> Add components\ble\device_manager

What else did I miss out?

I found this link devzone.nordicsemi.com/.../

Following the instructions will solve the problem. Add device_manager_peripheral.c to the project, not device_manager_central.c.
