Question

I am developing an OBEX OPP client application in android phone.Through the client application i will send an object to the non Android device (which will act as the OPP server).I have created the RFCOMM socket connection using the API

createRfcommSocketToServiceRecord(OPP_UUID); I have use the UUID of the OBEX Push i.e.

private static final UUID OPP_UUID = UUID .fromString("00001105-0000-1000-8000-00805F9B34FB");

I have observed that through this the socket connection is successful and I got the input and output stream of the socket to send and recieve the data.But when I send the data the data recieved the other device is not in the right format. What I mean by this is in the reciever device the data is recieved with the error. BT Air sniffer indicates that the in the retrieved_opcode Data is not present.OBEX response code is Bad request.

Can anyone guide me what is wrong in this ? or the steps to make an OBEX OPP connection with the device which is not paired.

你的宝贵意见将帮助我克服这一困难。

Thanks, Shekhar

你应该能够配对设备，你也可以通过设备上的蓝牙设置进行配对，但你不能像SPP通信那样直接连接和发送数据。

OBEX是一种协议，有自己的报头、数据包等。。

在安卓系统中，没有一个API可以通过OBEX进行通信，您可以通过编程进行使用。（您可以连接到设备，但之后您只能读取/写入字节）。

您可以通过obex通过以下几种方式将文件发送到配对设备：

使用ACTION_SEND意图，将弹出一个菜单，其中包含可以处理您想要发送的文件类型的应用程序，用户需要从中选择蓝牙，然后选择设备。

Intent share = new Intent(Intent.ACTION_SEND);
share.setType("image/jpeg");
share.putExtra(Intent.EXTRA_STREAM, Uri.parse(SDCardPath + "file.jpg"));
startActivity(Intent.createChooser(share, "Share Image"));

或者你可以使用另一种方法，如果你不想在你的应用程序中有任何对话框，请检查以下问题，它有一个可用解决方案的更新：

使用蓝牙OBEX对象推送配置文件（OPP）发送文件
