How to send NRF5340 TX power data during PAwR?

Question

Below is my change, set options to BT_LE_PER_ADV_OPT_USE_TX_POWER

static const struct bt_le_per_adv_param per_adv_params = {
	.interval_min = 0x0290, 
	.interval_max = 0x0290,   
	//.options = 0,  
	.options = BT_LE_PER_ADV_OPT_USE_TX_POWER, 
	.num_subevents = NUM_SUBEVENTS, 
	.subevent_interval = 0xfa,  
	.response_slot_delay = 0x0f,  
	.response_slot_spacing = 0x15,  
	.num_response_slots = NUM_RSP_SLOTS, 
};

But it always display Failed to set periodic advertising parameters (err -5), why?

My hardware is nrf5340DK, SDK is ncs 3.1 PAwR sample

Hi Yoyo, Opcode 0x2086 returns status 0x11. It's Unsupported Feature or Parameter Value. As far as I know our softdevice controller doesn't support BT_LE_PER_ADV_OPT_USE_TX_POWER yet. The Zephyr controller may support this. 
 You may have to think of using proprietary data to send Tx Power.
