Thank you very much for the answer. I have verified that it works! I guess BLE_GAP_ADV_FLAGS_LE_ONLY_GENERAL_DISC_MODE is for putting the BLE chip into discoverable mode forever.

If I set it to 0, the board never enter advertising state. Another strange thing is that if I set it to any value >180, the board does not enter advertising state.

You should look at the advertising timeout:

#define APP_ADV_TIMEOUT_IN_SECONDS      180                                         /**< The advertising timeout (in units of seconds). */

You can set it to 0x0000 to disable timeout.

Edit:

And you need to change

advdata.flags              = BLE_GAP_ADV_FLAGS_LE_ONLY_LIMITED_DISC_MODE;

advdata.flags              = BLE_GAP_ADV_FLAGS_LE_ONLY_GENERAL_DISC_MODE;

in advertising_init()
