车库门的保密设置是非常重要的，下面我们就给大家介绍一下它的保密性设置。 Garage door security settings are very important, we will introduce to you the confidentiality of its settings. 对于蓝牙间的相互配对，可以在程序里写入蓝牙从模块的地址，打开手机软件以后，就可以根据地址自动搜索蓝牙从模块的芯片，第一次成功配对连接以后就会记住该地址，此后打开手机界面，就会自动和蓝牙从模块进行搜索配对和连接。 The matching between Bluetooth, Bluetooth module can be written from the address in the program, after the open mobile phone software, can automatically search the Bluetooth module according to the address from the chip, the first successful pairing after connecting will remember the address, then open the mobile phone interface, and Bluetooth module will automatically search for matching and connecting from. 蓝牙系统虽然在多方面建立了安全机制，但它的安全机制还是不完全的，可能会遭受到多方面的攻击。对于安全性能要求较低的个人网络，蓝牙技术的安全性能还是比较高的，但由于该项设计涉及财产安全，所以笔者采取了一系列的安全措施，在设置配对密码的时候，要求用户必须设置字母与数字相结合的安全系数较高的密码，当密码连续3次输入错误时，需要手动打开车库门，以保证汽车用户的安全性。 Although Bluetooth system has established security mechanism in many aspects, its security mechanism is still incomplete, and it may be attacked in many ways. For the safety performance requirements of low personal network, the safety performance of Bluetooth technology is still relatively high, but because the design involves the property safety, so the author takes a series of security measures, when setting the pairing password, the user must set a higher safety factor of letters and numbers combined with the password, when password 3 consecutive input errors, need to manually open the garage door, in order to ensure the safety of car users.
