[nRF Connect SDK] How to change BT name

[Tim Hwang]

Target nRF52832(nrf52dk_nrf52832)
SDK NCS v1.9.1
Base source
1. C:\Users\user\ncs\v1.9.1\nrf\samples\bluetooth\peripheral_hids_keyboard
2. C:\Users\user\ncs\v1.9.1\nrf\samples\bluetooth\peripheral_hids_keyboard
My project require two mode(HID and NUS).

I received bt name via UART before call bt_enable(NULL);
but name information already defined at compile time.
static const struct bt_data sd[] = {
BT_DATA(BT_DATA_NAME_COMPLETE, DEVICE_NAME, DEVICE_NAME_LEN),
};

I found good option and API but it did not work.
CONFIG_BT_DEVICE_NAME_DYNAMIC
bt_set_name("new name")

When do I call bt_set_name() ?
Can you please guide for me?

String DEVICE_NAME = "Uart name";
uint8_t DEVICE_NAME_LEN = (sizeof(DEVICE_NAME) - 1);

static const struct bt_data ad[] = {
	BT_DATA_BYTES(BT_DATA_FLAGS, (BT_LE_AD_GENERAL | BT_LE_AD_NO_BREDR)),
	BT_DATA(BT_DATA_NAME_COMPLETE, DEVICE_NAME, DEVICE_NAME_LEN),
};

static const struct bt_data sd[] = {
	BT_DATA_BYTES(BT_DATA_UUID128_ALL, BT_UUID_NUS_VAL),
};

#define BT_LE_ADV_CONN_TEST BT_LE_ADV_PARAM(BT_LE_ADV_OPT_CONNECTABLE, \
                                               adv_param_interval_min, \
                                               adv_param_interval_max, NULL)

err = bt_le_adv_start(BT_LE_ADV_CONN_TEST, ad, ARRAY_SIZE(ad), sd, ARRAY_SIZE(sd));
if (err) {
	LOG_ERR("Advertising failed to start (err %d)", err);
	return;
}
