使用ble_gatt_server例程手机蓝牙可配对但是无法连接，怎么解决？

我所用的设备是合宙的esp32c3，所用的编辑器为vscode，idf的版本应该是4.3-4.4左右。例程中我主要更改了passkey和输入方式，在配对时手动输入pin码进行配对，在进行重启手机，复位芯片，更换芯片之后，手机的蓝牙界面一直都无法进行连接，尽管已经配对上了，app_main的代码如下：Code: Select all
void app_main(void){    esp_err_t ret;    // Initialize NVS.    ret = nvs_flash_init();    if (ret == ESP_ERR_NVS_NO_FREE_PAGES || ret == ESP_ERR_NVS_NEW_VERSION_FOUND) {        ESP_ERROR_CHECK(nvs_flash_erase());        ret = nvs_flash_init();    }    ESP_ERROR_CHECK( ret );    ESP_ERROR_CHECK(esp_bt_controller_mem_release(ESP_BT_MODE_CLASSIC_BT));    esp_bt_controller_config_t bt_cfg = BT_CONTROLLER_INIT_CONFIG_DEFAULT();    ret = esp_bt_controller_init(&bt_cfg);    if (ret) {        ESP_LOGE(GATTS_TABLE_TAG, "%s init controller failed: %s", __func__, esp_err_to_name(ret));        return;    }    ret = esp_bt_controller_enable(ESP_BT_MODE_BLE);    if (ret) {        ESP_LOGE(GATTS_TABLE_TAG, "%s enable controller failed: %s", __func__, esp_err_to_name(ret));        return;    }    ESP_LOGI(GATTS_TABLE_TAG, "%s init bluetooth", __func__);    ret = esp_bluedroid_init();    if (ret) {        ESP_LOGE(GATTS_TABLE_TAG, "%s init bluetooth failed: %s", __func__, esp_err_to_name(ret));        return;    }    ret = esp_bluedroid_enable();    if (ret) {        ESP_LOGE(GATTS_TABLE_TAG, "%s enable bluetooth failed: %s", __func__, esp_err_to_name(ret));        return;    }    ret = esp_ble_gatts_register_callback(gatts_event_handler);    if (ret){        ESP_LOGE(GATTS_TABLE_TAG, "gatts register error, error code = %x", ret);        return;    }    ret = esp_ble_gap_register_callback(gap_event_handler);    if (ret){        ESP_LOGE(GATTS_TABLE_TAG, "gap register error, error code = %x", ret);        return;    }    ret = esp_ble_gatts_app_register(ESP_HEART_RATE_APP_ID);    if (ret){        ESP_LOGE(GATTS_TABLE_TAG, "gatts app register error, error code = %x", ret);        return;    }    /* 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_REQ_SC_MITM_BOND;     //bonding with peer device after authentication    esp_ble_io_cap_t iocap = ESP_IO_CAP_OUT;           //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 = 100101;    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));    /* If your BLE device acts as a Slave, the init_key means you hope which types of key of the master should distribute to you,    and the response key means which key you can distribute to the master;    If your BLE device acts as a master, the response key means you hope which types of key of the slave should distribute to you,    and the init key means which key you can distribute to the slave. */    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));    /* Just show how to clear all the bonded devices     * Delay 30s, clear all the bonded devices     *     * vTaskDelay(30000 / portTICK_PERIOD_MS);     * remove_all_bonded_devices();     */}
随后芯片从启动到配对蓝牙的日志如下，我看了一下应该是没有问题的，但点击手机的蓝牙选项卡就是没有连接的反应（小米10s）

已经尝试了许多方法未曾解决，希望能得到各位的帮助，谢谢！
