The Bluetooth Classic address stays the same.经典蓝牙地址保持不变。 The LE address is random and stays the same while connected, but otherwise an Android device changes its LE address regularly. LE 地址是随机的，并且在连接时保持不变，但除此之外，Android 设备会定期更改其 LE 地址。 The address could be the same for a few connections, but will then change.几个连接的地址可能相同，但随后会发生变化。 This "feature" cannot be disabled.不能禁用此“功能”。 Also, an Android app is not allowed to know its own LE address.此外，不允许 Android 应用程序知道自己的 LE 地址。 So use a Classic connection.所以使用经典连接。
