keep advertising when ble is conneted

[33]

Hi,

      I use the SDK 12.3  ,example ：nRF5_SDK_12.3.0_d7731ad\nRF5_SDK_12.3.0_d7731ad\examples\ble_peripheral\ble_app_uart

    I want keep advertising，I use the code as follow：

static void non_connectable_advertising_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_NONCONN_IND ;
adv_params.p_peer_addr = NULL;
adv_params.fp = BLE_GAP_ADV_FP_ANY;
adv_params.interval = MSEC_TO_UNITS(500,UNIT_0_625_MS);
adv_params.timeout = 1800;

err_code = sd_ble_gap_adv_start(&adv_params);
if(err_code!=NRF_SUCCESS)
printf("non_connectable_advertising result:%d",err_code);
// APP_ERROR_CHECK(err_code);
}

i add this in   ble event：BLE_GAP_EVT_CONNECTED。

static void on_ble_evt(ble_evt_t * p_ble_evt)
{
uint32_t err_code;

switch (p_ble_evt->header.evt_id)
{
case BLE_GAP_EVT_CONNECTED:
{
err_code = bsp_indication_set(BSP_INDICATE_CONNECTED);
APP_ERROR_CHECK(err_code);
m_conn_handle = p_ble_evt->evt.gap_evt.conn_handle;
non_connectable_advertising_init();
}break; // BLE_GAP_EVT_CONNECTED

but  i get err_code:NRF_ERROR_INVALID_PARAM .

So  what shoule I do to keep advertising when connected?

for which function do you get error with :NRF_ERROR_INVALID_PARAM ?

It‘is sd_ble_gap_adv_start(&adv_params);

hi，what should i do？ thanks。

It works normally if I use your snippet in the beacon example.
