PSoC4外设与智能手机之间的专用随机可解析地址和绑定

大家好，
我试图实现以下场景：使用PSoC 4 BLE外围设备，我更新了隐私示例，并尝试在我的项目中使用它。我用一个公共地址启动外围设备，然后用一个Android智能手机连接到设备上，用固定的密钥配对，绑定设备，然后电话断开。在断开事件之后，我的外围设备的地址变成私有随机可解析，这是我想要的，甚至在没有连接或每次连接/断开事件到达时，即使在几分钟内它也会再次改变。一切都是好的，但我的问题是，在我与智能手机从外围设备断开，地址变为私有之后，我再也无法与我的智能手机重新连接。有没有人知道Android本身可以解决一个地址，或者应用程序应该每次扫描一个设备，并试图解决自己的地址？我想重新连接到一个保税设备没有扫描，但我不知道这是可能的。
如果有人经历过这一点，那么暗示不仅仅是受欢迎的。
谢谢您，
玛丽安
更新信息：我的设备的安全性被设置为模式1，认证加密配对，严格配对，显示为IO能力（即使这不是完全正确的，该设备没有I/O能力，但我想使用一个固定的密钥）。我观察到，由智能手机发起的绑定和密钥交换是可以的。在断开事件和地址变为私有之后，我可以扫描所有设备，找到我需要的定向地址，并且可以在没有任何绑定的情况下连接到它。现在的问题是：在连接和访问一个服务（例如电池级别）之后，我就不能再做任何事情了。如果我尝试阅读比配对WiNoW将再次弹出，无论我进入什么设备断开连接。
更新信息2：
这里是一个新的更新和项目附加。除了处理两个状态机来处理这些绑定和隐私任务之外，我消除了所有代码。请注意在BuffHordL.C中有些代码是注释的，因为它在这个测试项目中没有意义，尤其是通过按下一个按钮来完成绑定的事实，而在项目中它是在重置时完成的。
SIG中的电池级别在读时已经加密和认证。因此，这可能再次触发配对窗口。我不是Android或IOS将如何处理这个问题的专家，但如果我删除加密，认证比一切都好。但我不想修改这个，而且我仍然希望在其他自定义特性上有一些隐私，即使在绑定之后，只有电话才能解决这个地址。
其他信息：与CyPress软件和CyScript在PC上，当重新连接到私人地址，它会弹出配对，但OK后说，完成没有输入引脚完成。
我的另一个问题是：我在外围处理这个过程有什么不对吗？Android上的应用程序有问题吗？我应该投资一些时间吗？
如果有人能给我指出一个更正确的方向，那就太好了。谢谢您！

  Hello everybody,

I am trying to implement the following scenario: using a PSoC 4 BLE peripheral I updated the privacy example and I am trying to use it in my project. I start the peripheral using a public address; then I connect with an android smartphone to the device, pair it using a fixed passkey, bond the device and afterwards the phone disconnects. After the disconnecting event, the address of my peripheral becomes private random resolvable which is what I want, it even changes ones at a couple of minutes again if there is no connection or every time a connection/disconnection event arrived. Everything is good, but my problem is the following, after I disconnect with the smartphone from the peripheral and the address become private I am not able to reconnect with my smartphone again. Does anyone know if android itself can resolve an address or if the application should scan every time for a device and try to resolve itself the address? I would like to reconnect to a bonded device without scanning, but I do not know if this is possible.

If anyone experienced this, a hint is more than welcomed.

Thank you,
Marian

Update info: The security of my device is set to Mode 1, authenticated pairing with encryption, Strict pairing, Display as IO capability(even if this is not entirely correct, the device has no i/o capabilities but I want to use a fixed passkey for this). I observe that the bonding initiated by the smartphone and the exchange of keys is ok. After disconnect event and the address become private I can scan all devices, find the one I need with the orivate address and can connect to it without any bonding. The problem is now the following: after connection and accessing a service(ex. battery level) I am no longer able to do anything. If I try a read than the pairing winodw will pop up again and no matter what I enter the device disconnects.

Update info 2:
Here is a new Update and the project attached. I eliminate all the code except my two state machines that handle this bonding and privacy tasks. Please note in BLEHandler.c that some code is commented since it makes no sense in this test project, especially the fact that remove bonding is done by pressing a button and in the project it is done at reset.

The battery level as it is in SIG has encryption and authenticated on Read. Therefore indeed that may trigger the pairing window again. I am not an expert in how Android or iOS will treat this but if I remove the encryption an authentication than everything is fine. But I do not want to modify this, and I still want some privacy on other custom characteristics, even if after a bonding only that phone can resolve the address.

Other Info: with the cypress dongle and cysmart on PC, when reconnect to the private address, it will pop up the pairing but after ok it says paring completed without the entering pin.

One of my other questions will be: Is there something wrong in how I handle this process in the peripheral? Is there a problem with the application on android and there I should invest some time?

It would be great if someone can point me in a more correct direction. Thank you!
