I am using the nRF52832 development board, S132 and SDK11.0, I have some questions about Bluetooth pairing,The project under the link：examples\ble_peripheral\ble_app_uart\pca10040\s132\arm4，Pairing process in the serial program is not implemented。so BLE can Send data without pairing？The program never runs BLE_GAP_EVT_SEC_PARAMS_REQUEST。
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;
break;
case BLE_GAP_EVT_DISCONNECTED:
err_code = bsp_indication_set(BSP_INDICATE_IDLE);
APP_ERROR_CHECK(err_code);
m_conn_handle = BLE_CONN_HANDLE_INVALID;
break;
case BLE_GAP_EVT_SEC_PARAMS_REQUEST:
// Pairing not supported
err_code = sd_ble_gap_sec_params_reply(m_conn_handle, BLE_GAP_SEC_STATUS_PAIRING_NOT_SUPP, NULL, NULL);
APP_ERROR_CHECK(err_code);
break;
case BLE_GATTS_EVT_SYS_ATTR_MISSING:
// No system attributes have been stored.
err_code = sd_ble_gatts_sys_attr_set(m_conn_handle, NULL, 0, 0);
APP_ERROR_CHECK(err_code);
break;
default:
// No implementation needed.
break;
}
}
