Config for using sdc_hci_cmd functions

Question

Hello, 
 I'm using a nRF5340 DK and ncs version 2.3.0. 
 What i try is, to use calls like 
 
 sdc_hci_cmd_vs_zephyr_read_chip_temp() that is available in header file sdc_hci_vs.h (ncs/v2.3.0/nrfxlib/softdevice_controller/include) and source file hci_internal.c (
cs\v2.3.0
rf\subsys\bluetooth\controller) or 
 bt_ctlr_set_public_addr() that uses sd_hci_cmd_vs_zephyr_write_bd_addr() function that is available in the hci_driver.c and the same header file. 
 
 I'm always getting the error messages: 
 
 undefined reference to `sdc_hci_cmd_vs_zephyr_read_chip_temp' and 
 undefined reference to `bt_ctlr_set_public_addr' 
 
 So I'm pretty sure I'm missing a CONFIG in my prj.conf, but can't find the right one. Any Ideas, what i need to add here? 
 I've started my evaluation with the zephyr beacon sample. 
 Thanks a lot.

Hi Steffen, I'm taking over the case as I have done some more test related to the topic. I haven't tested on SDC_HCI_OPCODE_CMD_VS_ZEPHYR_READ_CHIP_TEMP but instead using BT_HCI_OP_VS_READ_CHIP_TEMP which is similar to how we control TX Power. And I can get good result out, I can see temperature around 0x19, 0x1a meaning 25-26 Celsius. 
 int temperature_measure(void)
{

	int err = 0;
	struct net_buf *buf, *rsp = NULL;
	struct bt_hci_rp_vs_read_chip_temp *cmd_params;
	struct bt_hci_rp_vs_read_chip_temp *rsp_params;

	buf = bt_hci_cmd_create(BT_HCI_OP_VS_READ_CHIP_TEMP, sizeof(*cmd_params));
	if (!buf) {
 printk("Could not allocate command buffer");
 return -ENOMEM;
	}

	cmd_params = net_buf_add(buf, sizeof(*cmd_params));

	err = bt_hci_cmd_send_sync(BT_HCI_OP_VS_READ_CHIP_TEMP, buf, &rsp);
	if (err) {
 printk("bt_hci_cmd_send_sync failed (err: %d)",err);
 return err;
	}

	rsp_params = (void *) rsp->data;
	printk("result: 0x%x",rsp_params->temps);
	net_buf_unref(rsp);

	return 0;
}
