BLE how to disconnect client if not bonded

[gaysin1111]

i create GATTS with static key auth procedure. But if device not bonded i also can to connect without key and read/write service characteristics.
How to disconnect device if it not bonded?

Here code of secure configuration

Code: Select all

static void ble_set_secure(void)
{
    /* set the security iocap & auth_req & key size & init key response key parameters to the stack*/
    esp_ble_auth_req_t auth_req = ESP_LE_AUTH_BOND;     //bonding with peer device after authentication
    esp_ble_io_cap_t iocap = ESP_IO_CAP_IO;           //set the IO capability to No output No input
    uint8_t key_size = 16;      //the key size should be 7~16 bytes
    // uint8_t init_key = ESP_BLE_ENC_KEY_MASK | ESP_BLE_ID_KEY_MASK;
    // uint8_t rsp_key = ESP_BLE_ENC_KEY_MASK | ESP_BLE_ID_KEY_MASK;
    //set static passkey
    uint32_t passkey = 123456;
    uint8_t auth_option = ESP_BLE_ONLY_ACCEPT_SPECIFIED_AUTH_DISABLE;
    uint8_t oob_support = ESP_BLE_OOB_DISABLE;
    esp_ble_gap_set_security_param(ESP_BLE_SM_SET_STATIC_PASSKEY, &passkey, sizeof(uint32_t));
    esp_ble_gap_set_security_param(ESP_BLE_SM_AUTHEN_REQ_MODE, &auth_req, sizeof(uint8_t));
    esp_ble_gap_set_security_param(ESP_BLE_SM_IOCAP_MODE, &iocap, sizeof(uint8_t));
    esp_ble_gap_set_security_param(ESP_BLE_SM_MAX_KEY_SIZE, &key_size, sizeof(uint8_t));

    esp_ble_gap_set_security_param(ESP_BLE_SM_ONLY_ACCEPT_SPECIFIED_SEC_AUTH, &auth_option, sizeof(uint8_t));
    esp_ble_gap_set_security_param(ESP_BLE_SM_OOB_SUPPORT, &oob_support, sizeof(uint8_t));
    
    /*esp_ble_gap_set_security_param(ESP_BLE_SM_SET_INIT_KEY, &init_key, sizeof(uint8_t));
    esp_ble_gap_set_security_param(ESP_BLE_SM_SET_RSP_KEY, &rsp_key, sizeof(uint8_t));*/
