Android的蓝牙连接其他蓝牙设备 [英] Android Bluetooth to connect another bluetooth device

问题描述

Im做基于蓝牙的应用程序，我想连接其他设备，如诺基亚设备和打印机。

Im doing bluetooth based application, I want to connect other devices like nokia devices, and printer.

我指的是Android的蓝牙文件 http://developer.android.com/导/主题/连接/ bluetooth.html 。它演示了所有基本的蓝牙API capabilites，而我做这所有的事情

I refer the android bluetooth documentation http://developer.android.com/guide/topics/connectivity/bluetooth.html. It demonstrates all the fundamental Bluetooth API capabilites, And I did these all the things

Scanning for other Bluetooth devices
Querying the local Bluetooth adapter for paired Bluetooth devices
Establishing RFCOMM channels/sockets
Connecting to a remote device
Transfering data over Bluetooth

我得到借鉴BluetoothChat，Android的样本。

i get reference from BluetoothChat, samples of android.

BluetoothChat This application send data to another android device but for that this application must be installed in both the devices.

像这样<一个href="http://stackoverflow.com/questions/6227498/how-to-send-file-from-android-device-to-other-device-through-bluetooth-by-$c$c">How通过蓝牙由code 从Android设备发送文件到其它设备

Like this How to send file from Android device to other device through Bluetooth by code

我要的是

1. 我想从一个设备从我的应用程序发送文件到另一台设备，而且也适用甚至是另一个不运行我们的应用程序的设备。即接收设备还能够使用默认的蓝牙接收文件。

这是可能的机器人？

推荐答案

您可以轻松地做两BT的设备之间的连接。 你只需要调用

You can do connection between two BT devices easily. You just need to call

createRfcommSocketToServiceRecord(UUID)

与UUID的理解接收装置。 对于文件传输操作的UUID必须等于（举例）00001106-0000-1000-8000-00805F9B34FB（文件传输服务）

with UUID that understand receiver device. For file transfer action UUID must be equal (for example) to 00001106-0000-1000-8000-00805F9B34FB (File transfer service)

所以，你的连接code威力看起来像下面

So you connection code might looks like code below

BluetoothDevice类设备= mBluetoothAdapter.getRemoteDevice（00：0A：94：16：77：A0）; 的BluetoothSocket ClientSocket的;

BluetoothDevice device = mBluetoothAdapter.getRemoteDevice("00:0A:94:16:77:A0"); BluetoothSocket clientSocket;

try {
    log(TAG, "Remote device " + device);
    ParcelUuid[] uuids = device.getUuids();
    boolean isFileTransferSupported = false;
    UUID ftpUID = UUID.fromString("00001106-0000-1000-8000-00805F9B34FB");
    // Check if remote device supports file transfer
    for (ParcelUuid parcelUuid: uuids) {
        if (parcelUuid.getUuid().equals(ftpUID)) {
            isFileTransferSupported = true;
            break;
        }
    }
    if (!isFileTransferSupported) {
        log(TAG, "Remote bluetooth device does not supports file transfer ");
        return;
    }
    clientSocket = device.createRfcommSocketToServiceRecord(ftpUID);
    clientSocket.connect();
} catch (IOException e) {
    return;
}
