无法连接采用Android BluetoothProfile蓝牙保健器佛拉 [英] Unable to connect to bluetooth Health Device Fora using Android BluetoothProfile
问题描述
我想通过Android的BluetoothPRofile连接到佛拉温度计和获得的读数。
以下是我的approoach： -
I want to connect to Fora thermometer via Android BluetoothPRofile and get the reading. Following is my approoach :-
-
在OnCreate（）中我写了这片code的： -
In OnCreate() i have written this piece of code :-
if (!mBluetoothAdapter.getProfileProxy(this, mBluetoothServiceListener,
BluetoothProfile.HEALTH)) {
Toast.makeText(this, "No Health Profile Supported",
Toast.LENGTH_LONG);
return;
}
这将触发这是下面提到的mBluetoothServiceListener回调： -
This triggers the mBluetoothServiceListener callback which is mentioned below :-
@SuppressLint("NewApi")
private final BluetoothProfile.ServiceListener mBluetoothServiceListener =
new BluetoothProfile.ServiceListener() {
public void onServiceConnected(int profile, BluetoothProfile proxy) {
Log.d(TAG, "onServiceConnected to profile: " + profile + " while health is " + BluetoothProfile.HEALTH);
if (profile == BluetoothProfile.HEALTH) {
mBluetoothHealth = (BluetoothHealth) proxy;
if (Log.isLoggable(TAG, Log.DEBUG))
Log.d(TAG, "onServiceConnected to profile: " + profile);
}
else if(profile == BluetoothProfile.HEADSET)
{
Log.d(TAG, "onServiceConnected to profile: " + profile);
}
}
public void onServiceDisconnected(int profile) {
if (profile == BluetoothProfile.HEALTH) {
mBluetoothHealth = null;
}
}
};
这之后附近的蓝牙设备的code搜索并显示在列表中。
该列表项的onclicklistener调用下面code： -
After this the code searches for nearby bluetooth devices and shows it in the list. The onclicklistener of that list item calls the following code :-
boolean bool = mBluetoothHealth.registerSinkAppConfiguration(TAG, HEALTH_PROFILE_SOURCE_DATA_TYPE, mHealthCallback);
// where HEALTH_PROFILE_SOURCE_DATA_TYPE = 0x1008 (it's a body thermometer)
在设好注册过程完成我尝试将设备连接是这样的： -
Once the registeration process is done i try to connect the device like this :-
boolean bool = mBluetoothHealth.connectChannelToSource(mDevice, mHealthAppConfig);
在所有上述步骤完成则BluetoothHealthCallback被称为每当
该设备的连接状态的变化。
Once all the above steps are done then the BluetoothHealthCallback is called whenever the device connection state changes
private final BluetoothHealthCallback mHealthCallback = new BluetoothHealthCallback() {
// Callback to handle application registration and unregistration events. The service
// passes the status back to the UI client.
public void onHealthAppConfigurationStatusChange(BluetoothHealthAppConfiguration config,
int status) {
if (status == BluetoothHealth.APP_CONFIG_REGISTRATION_FAILURE) {
mHealthAppConfig = null;
} else if (status == BluetoothHealth.APP_CONFIG_REGISTRATION_SUCCESS) {
mHealthAppConfig = config;
} else if (status == BluetoothHealth.APP_CONFIG_UNREGISTRATION_FAILURE ||
status == BluetoothHealth.APP_CONFIG_UNREGISTRATION_SUCCESS) {
}
}
// Callback to handle channel connection state changes.
// Note that the logic of the state machine may need to be modified based on the HDP device.
// When the HDP device is connected, the received file descriptor is passed to the
// ReadThread to read the content.
public void onHealthChannelStateChange(BluetoothHealthAppConfiguration config,
BluetoothDevice device, int prevState, int newState, ParcelFileDescriptor fd,
int channelId) {
if (Log.isLoggable(TAG, Log.DEBUG))
Log.d(TAG, String.format("prevState\t%d ----------> newState\t%d",
prevState, newState));
if (prevState == BluetoothHealth.STATE_CHANNEL_DISCONNECTED &&
newState == BluetoothHealth.STATE_CHANNEL_CONNECTED) {
if (config.equals(mHealthAppConfig)) {
mChannelId = channelId;
(new ReadThread(fd)).start();
} else {
}
} else if (prevState == BluetoothHealth.STATE_CHANNEL_CONNECTING &&
newState == BluetoothHealth.STATE_CHANNEL_DISCONNECTED) {
} else if (newState == BluetoothHealth.STATE_CHANNEL_DISCONNECTED) {
if (config.equals(mHealthAppConfig)) {
} else {
}
}
}
};
在上述情况下，我得到的BluetoothHealthCallback precisely 2倍： -
In the above case i get the BluetoothHealthCallback precisely 2 times :-
-
我第一次拿到prevState = BluetoothHealth.STATE_CHANNEL_DISCONNECTED和
newState = BluetoothHealth.STATE_CHANNEL_CONNECTING
First Time i get the prevState = BluetoothHealth.STATE_CHANNEL_DISCONNECTED and newState = BluetoothHealth.STATE_CHANNEL_CONNECTING
而在我第二次获得prevState = BluetoothHealth.STATE_CHANNEL_CONNECTING和
newState = BluetoothHealth.STATE_CHANNEL_DISCONNECTED
While in Second time i get the prevState = BluetoothHealth.STATE_CHANNEL_CONNECTING and newState = BluetoothHealth.STATE_CHANNEL_DISCONNECTED
即。在尝试连接到该设备，但它不是succesfull。
此外，在这两个回调ParcelFileDescriptor为空
i.e. the attempt is made to connect to the device but it is not succesfull. Also in both the callbacks the ParcelFileDescriptor is null
*注：该设备已经配对
*Note : The device is already paired
推荐答案
你觉得你下面的if语句是正确的？
Do you think yours below "if" statement is right?
如果（prevState == BluetoothHealth.STATE_CHANNEL_DISCONNECTED＆放大器;＆安培;
newState == BluetoothHealth.STATE_CHANNEL_CONNECTED）{
if (prevState == BluetoothHealth.STATE_CHANNEL_DISCONNECTED && newState == BluetoothHealth.STATE_CHANNEL_CONNECTED) {
这应该是（因为它发生的经典蓝牙设备）
It should be either (as it happen for classic Bluetooth devices)
如果（prevState == BluetoothHealth.STATE_CHANNEL_CONNECTING＆放大器;＆安培;
newState == BluetoothHealth.STATE_CHANNEL_CONNECTED）{
if (prevState == BluetoothHealth.STATE_CHANNEL_CONNECTING && newState == BluetoothHealth.STATE_CHANNEL_CONNECTED) {
当你连接，然后再连接
或者我可能只是
如果（newState == BluetoothHealth.STATE_CHANNEL_CONNECTED）{
if (newState == BluetoothHealth.STATE_CHANNEL_CONNECTED) {
和其他if语句相同的校正。
And same correction for other "if" statement.
另外，
请问设备支持的配对并连接选项？如果是的话，那么你可以尝试连接它手动。
Also, Does device support paired and connected option? If yes then you may try to connect it manually.
