It won't make your board consume any more power when advertising. But it will of course drain more power over time, as the board never stops advertising.
You can try to reduce the power consumption by changing the advertisement interval etc.

Thanks to you, I've solved it. I heartily thank you.

ADD. Advertise forever Does this function consume a lot of battery? Is there a way to reduce battery consumption using this function?

Hi JaeHo!

As max said in his answer, you should set the advertisement timeout to zero:

#define APP_ADV_TIMEOUT_IN_SECONDS     0

However, if you want to advertise forever you need to set the LE General Discoverable Mode flag, not the LE Limited Discoverable Mode flag.

So in advertising_init(), change the:

advdata.flags = BLE_GAP_ADV_FLAGS_LE_ONLY_LIMITED_DISC_MODE;

advdata.flags = BLE_GAP_ADV_FLAGS_LE_ONLY_GENERAL_DISC_MODE;

and your device should advertise forever.

Hope that works.
Best regards,
Joakim.
