Sorry, I found the place of the "Client Characteristic Configuration" set security policy. in custom_add_in_characteristic() function in custom_helper.cpp file error_t custom_add_in_characteristic(uint16_t service_handle, ble_uuid_t *p_uuid, uint8_t properties, SecurityManager::SecurityMode_t requiredSecurity, uint8_t *p_data, uint16_t min_length, uint16_t max_length, const uint8_t *userDescriptionDescriptorValuePtr, uint16_t userDescriptionDescriptorValueLen, bool readAuthorization, bool writeAuthorization, ble_gatts_char_handles_t p_char_handle) { / Characteristic metadata */ ble_gatts_attr_md_t cccd_md; ble_gatt_char_props_t char_props;

memcpy(&char_props, &properties, 1);

if (char_props.notify || char_props.indicate) {
    /* Notification requires cccd */
    memclr_( &cccd_md, sizeof(ble_gatts_attr_md_t));
    cccd_md.vloc = BLE_GATTS_VLOC_STACK;
    BLE_GAP_CONN_SEC_MODE_SET_OPEN(&cccd_md.read_perm);
    **//BLE_GAP_CONN_SEC_MODE_SET_ENC_WITH_MITM(&cccd_md.write_perm);**
    BLE_GAP_CONN_SEC_MODE_SET_OPEN(&cccd_md.write_perm);
}
