Question

我与硬件建立了连接，每10秒钟后数据会返回一次。返回的数据没有告诉我什么，我怎么能解释它？

修改

打开附件：

public func openAccessory() {
        let _accessories = getConnectedAccessories()
        var _accessory: EAAccessory?

        for acsy in _accessories {
            if acsy.protocolStrings.contains("com.protocol.link") {
                _accessory = acsy
            }
        }
        if _accessory != nil {
            let session = EASession(accessory: _accessory!, forProtocol: "com.protocol.link")
            if session != nil {
                guard let inputStream2 = session?.inputStream else {
                    return
                }
                inputStream2.delegate = self
                inputStream2.schedule(in: .current, forMode: .defaultRunLoopMode)
                inputStream = inputStream2
                inputStream.open()
                session?.outputStream?.delegate = self
                session?.outputStream?.schedule(in: .current, forMode: .defaultRunLoopMode)
                session?.outputStream?.open()
            }
        }
    }

阅读流：

func stream(_ aStream: Stream, handle eventCode: Stream.Event) {
        switch eventCode{
        case Stream.Event.hasBytesAvailable:
            if (aStream == inputStream) {
                var buffer = [UInt8](repeating: 0, count: 9)
                while (inputStream.hasBytesAvailable) {
                    let bytesRead: Int = inputStream.read(&buffer, maxLength: buffer.count)
                    if bytesRead > 0 {
                        let data = Data(bytes: buffer)
                        let answer = String.init(data: data, encoding: .ascii)
                        print(answer ?? "")
                    }
                }
            }
        default:
            print("No bytes available")
        }
    }

我的输出仍然相同：

但得到了一些额外的信息：

绑定率为115200 - 我知道如何通过putty设置它，并且收到的消息是应该的。
在我与我的链接（com.protocol.link）建立连接之后，它是一条电缆，通过它我与LMU一致，我需要配置正确的参数（23字节）：

{0x08,0x00,0x00,0x00,0x00,0x03,0x00,0xC2,0x01,0x00,0x00,0x00,0x00,0x00,0x00,0x3E，0x00,0x00,0x00,0x00,0x00,0x00,0x01}
我为LMU找到了Guide - 他们说我需要使用套接字端口和UDP协议，但我已经与设备建立了连接，但是收到的消息并不像我所说的那样。提前致谢！

使用绑定速率配置外部附件 - 解释输出流
