[当我尝试读取需要通过RPI 3B上的GattTool加密的BLE特性时
gatttool -b 04:EE:03:B1:47:DF --char-read --handle=0x000e --sec-level=low
其结果为错误特征值/描述符读取失败：请求属性遇到了不太可能的错误
我尝试过/不使用--sec-level = low | medium | high

任何人都知道如何解决此配对问题？
我已经能够在iOS上进行配对（通过cordova BLE中央插件），这是打包的记录器：https://gist.github.com/buildog/f65fb3b0d5a75d0b6aad26a7d71e9433
我现在不如何通过Gatttool在Linux上模仿此过程。
这是配对容量不一致的设备本身的问题
远程设备说“不支持配对”，同时也说“错误：身份验证不足”，这当然是相互矛盾的。显然，它并不符合蓝牙规范。您拥有的远程设备是什么？
