non connectable advertise get error in SDK9.0.0

[qoboty]

non connectable advertise success when in SDK 8.0.0, however I got error code 0x00000007 when upgrade to SDK 9.0.0.

I find out error code 7 is NRF_ERROR_INVALID_PARAM, which params is wrong in SDK9 ? How to fix it? Thank you !

Below is the code:

#define NON_CONNECTABLE_ADV_INTERVAL    320
#define APP_CFG_NON_CONN_ADV_TIMEOUT    900
   static void advertising_nonConnect_init(void){
		
	  uint32_t err_code;
		ble_gap_adv_params_t adv_params;
    memset(&adv_params, 0, sizeof(ble_gap_adv_params_t));
    adv_params.type        =BLE_GAP_ADV_TYPE_ADV_SCAN_IND; //BLE_GAP_ADV_TYPE_ADV_NONCONN_IND;
    adv_params.p_peer_addr = NULL;                             
    adv_params.fp          = BLE_GAP_ADV_FP_ANY;
    adv_params.interval    = NON_CONNECTABLE_ADV_INTERVAL;
    adv_params.timeout     = APP_CFG_NON_CONN_ADV_TIMEOUT;

    err_code = sd_ble_gap_adv_start(&adv_params);
    APP_ERROR_CHECK(err_code);
}

Hey.

The maximum timeout is 180s. You can set it to 0 to advertise forever

[Anders Strand]

Discoverability modes are described in Part C, Section 4.1 of the Bluetooth Core spec.

The limited discoverable mode should be used by devices that need to be
discoverable only for a limited period of time, during temporary conditions, or
for a specific event.

This is why you cannot advertise forever in limited mode. I think our documention should be improved here, as this is not clear.

BLE_GAP_ADV_FLAG_BR_EDR_NOT_SUPPORTED means that classic bluetooth (Basic rate, enhanced data rate) is not supported.

Hi,

The Bluetooth Core spec 5.0 says this. Does it mean that it should not be discoverable when it is advertising in Non-discoverable mode. The question i am asking is about BLE not BR/EDR.

9.2.2 Non-Discoverable Mode
9.2.2.1 Description
A device configured in non-discoverable mode will not be discovered by any
device that is performing either the general discovery procedure or the limited
discovery procedure.

Thanks
