Bluetooth Helper Library
A library makes your app's bluetooth operation(for Smart Iot Hardware especially) so easy!
Don't forget give me a star :）
Feature
- Packaged common bluetooth operations, such as device discovery, connect the remote device and more.
btHelperClient.searchDevices(listener);- Sending messages is such as Http, you send a message to the remote device(not need to connect device firstly, such as Smart Iot Hardware) then you could get a response and a status code.
btHelperClient.sendMessage("20:15:03:18:08:63", item, true, new OnSendMessageListener() {
@Override
public void onSuccess(int status, String response) {
}
...
});Dependency
There are two ways:
- clone this project, and use as dependency
- just add following code to you build.gradle:
// Add it in your root build.gradle at the end of repositories
allprojects {
repositories {
...
maven { url "https://jitpack.io" }
}
}
// Add the dependency
dependencies {
compile 'com.github.a-voyager:BluetoothHelper:f71d40a98b'
}Usage
- Get the instance use a Context object to initialize
btHelperClient = BtHelperClient.from(MainActivity.this);- Send message to the remote device send message asynchronously, callback in main thread. parameters means: device's mac address, message object, if need to obtain response, SendMessageListener.
MessageItem item = new MessageItem("Hello");
btHelperClient.sendMessage("20:15:03:18:08:63", item, true, new OnSendMessageListener() {
@Override
public void onSuccess(int status, String response) {
// Call when send a message succeed, and get a response from the remote device
// status: the status describes ok or error.
// 1 respect the response is valid, -1 respect the response is invalid
// response: the response from the remote device, you can call response.getBytes() to get char[]
}
@Override
public void onConnectionLost(Exception e) {
e.printStackTrace();
}
@Override
public void onError(Exception e) {
e.printStackTrace();
}
});- Close connection just call close() method
@Override
protected void onDestroy() {
super.onDestroy();
btHelperClient.close();
}More API
- Search devices search devices with just calling searchDevices() method
btHelperClient.searchDevices(new OnSearchDeviceListener() {
@Override
public void onStartDiscovery() {
// Call before discovery devices
Log.d(TAG, "onStartDiscovery()");
}
@Override
public void onNewDeviceFound(BluetoothDevice device) {
// Call when found a new device
Log.d(TAG, "new device: " + device.getName() + " " + device.getAddress());
}
@Override
public void onSearchCompleted(List<BluetoothDevice> bondedList, List<BluetoothDevice> newList) {
// Call when the discovery process completed
Log.d(TAG, "SearchCompleted: bondedList" + bondedList.toString());
Log.d(TAG, "SearchCompleted: newList" + newList.toString());
}
@Override
public void onError(Exception e) {
e.printStackTrace();
}
});- Set filter use a filter to check if a given response is an expect data.
btHelperClient.setFilter(new Filter() {
@Override
public boolean isCorrect(String response) {
return response.trim().length() >= 5;
}
});To-Do List
- Listening data mode
- BtHelperServer
