从口腔B牙刷中读取数据 - 蓝牙4.1低能耗

Question

我目前正在努力将我的Oral B牙刷与入伍的智能功能集成在一起。牙刷通过蓝牙与显示生活数据的小屏幕进行通信。也可以在清洁之前或清洁期间将智能手机与口服b应用程序连接，并在那里显示实时值。按下蓝牙按钮后，我已经能够通过贵族（Node.js BLE模块）连接，连接到设备并读取也更新的服务和特征。一旦开始清洁过程，客户端就会断开连接，并且在清洁过程中不再可以建立连接，但它会再次起作用。牙刷有一个SDK和API，仅适用于ios和Android应用程序。 https://developer.oralb.com/

现在我的问题是如何在清洁过程中获取sdk或显示实时值？是否有身份验证或类似背后的东西？有没有人有类似设备或BLE设备的经验？
