我正在构建一个 iOS ble fido2 身份验证器。收到注册请求后，将以下注册响应（NONE 证明）作为 3 个块（块大小 101）发送。还确保成功接收到块但是 webauthn 客户端没有发送任何错误/确认/没有 ui 更改发生。

被这个问题困扰了很久。无法找出以下响应出了什么问题。

我相信你在蓝牙通信中遇到了MTU问题

假设这是从身份验证器到客户端的凭据响应

请注意，每个数据包中都有一个序列号，即第一个字节。

对于每个数据包，您可以使用以下方法：

result = peripheralManager.updateValue(packet, for: <...>, onSubscribedCentrals: <...>)

请务必检查结果，如果为 FALSE，则应调用此方法

func peripheralManagerIsReady(toUpdateSubscribers peripheral: CBPeripheralManager)

继续发送其余数据包
