我正在尝试开发一个 fido2 iOS BLE 身份验证器。截至目前，Can 能够宣传我的身份验证器并将其与 webauthn 客户端配对。在客户端验证我的广告数据后，它正在向“controlPoint”特征写入“authenticatorGetInfo(83000104)”请求。

根据 fido 规范，将以下响应发送到authenticatorGetInfo，

没有 cbor

{
3 = "EF6CF220-7066-4808-AA22-345C7888BC3F";
1 = ("FIDO_2_0");
}

使用 cbor 编码

[162、1、129、104、70、73、68、79、95、50、95、48、3、120、36、69、70、54、67、70、50、50、48、45、55 , 48, 54, 54, 45, 52, 56, 48, 56, 45, 65, 65, 50, 50, 45, 51, 52, 53, 67, 55, 56, 56, 56, 66, 67, 51 , 70]

发送响应后，收到 Fido2 一致性工具抛出的以下错误。我的问题是，CBOR 编码有什么问题吗？或者我在这里做错了什么？
