是否可以迅速将十六进制数据发送到A2DP蓝牙设备? [英] Is possible send hexadecimal data to A2DP Bluetooth Device in swift?

问题描述

我正在iOS上开发一个应用程序，该应用程序连接到Bluetooth A2DP设备，但无法发送十六进制指令来使其正常工作.有人可以帮我吗?我找不到信息.

I am developing an application on iOS that connects to a Bluetooth A2DP device but I can not send instructions in hexadecimal to make it work. Somebody could help me? I can not find information.

使用AVAudioSession.sharedInstance().currentRoute，我可以看到UID和设备名称，但无法发送数据.

With AVAudioSession.sharedInstance().currentRoute I can see the UID and the name of the device but not send data.

let route  = AVAudioSession.sharedInstance().currentRoute
    let outPort = route.outputs.first
    if let outPort = outPort {
        print("out port name:\(outPort.portName)")
   }

你能帮我吗?

谢谢！
