"Undefined Symbol" error message when using BLE_ADVERTISING_DEF macro

[Hammerfall]

Hello everybody

I'm trying to initialise an advertising module for my project.

When using the macro for creating an advertising instante I get the following:

BLE_ADVERTISING_DEF(my_adv);

After compiling I get:

.\_build\nrf52832_xxaa.axf: Error: L6218E: Undefined symbol ble_advertising_on_ble_evt (referred from main.o).
.\_build\nrf52832_xxaa.axf: Error: L6218E: Undefined symbol ble_advertising_on_sys_evt (referred from main.o).
Not enough information to list image symbols.
Not enough information to list load addresses in the image map.

What is missing?

Thanks for helping

Old post, but I met the same issue, and the responses provided here weren't enough.
So to resolve this issue don't forget to point the "ble_advertising.C" through Project manager (on SES).
