[英]How to create Bond or Pairing in BLE using RxAndroidBLE
我想為連接設備實現密碼或與BLE設備建立連接。 我有6個字節的密鑰 ,因此我們將如何使用RxAndroid庫創建綁定或配對並將密鑰發送到BLE設備。
在建立連接時,任何人都可以給我參考或文檔鏈接或演示鏈接來實現Passkey或創建綁定或配對 。
提前致謝!!
首先,您需要找到附近的設備。
public void registerDeviceForAnyNEwDeviceFound() {
// Register for broadcasts when a device is discovered.
mBluetoothAdapter.startDiscovery();
IntentFilter filter = new IntentFilter(BluetoothDevice.ACTION_FOUND);
registerReceiver(mSearchReceiver, filter);
Log.e("STATUS", "" +
mBluetoothAdapter.isDiscovering());
isSearchReceiverRegistered = true;
}
// Create a BroadcastReceiver for ACTION_FOUND.
private final BroadcastReceiver mSearchReceiver = new BroadcastReceiver() {
public void onReceive(Context context, Intent intent) {
String action = intent.getAction();
Log.e("SEARCH STARTED", "TRUE");
if (BluetoothDevice.ACTION_FOUND.equals(action)) {
// Discovery has found a device. Get the BluetoothDevice
// object and its info from the Intent.
try {
BluetoothDevice device = intent.getParcelableExtra(BluetoothDevice.EXTRA_DEVICE);
String deviceName = device.getName();
String deviceHardwareAddress = device.getAddress(); // MAC address
Device mDevice = new Device();
mDevice.setDeviceName(deviceName);
mDevice.setDeviceAddress(deviceHardwareAddress);
mDevice.setmBluetoothDevice(device);
Log.e("Discovered DEVICE", deviceName);
Log.e("BOND STATE", "" + device.getBondState());
nearbyDeviceList.add(mDevice);
mNearbyDeviceRecAdapter.notifyDataSetChanged();
} catch (Exception e) {
Log.e("EXCEPTION", e.getLocalizedMessage());
}
}
}
};
然后,您需要注冊另一個BroadCastReceiver,此接收器將監聽與您要配對的設備的綁定更改。
IntentFilter filter = new IntentFilter(BluetoothDevice.ACTION_BOND_STATE_CHANGED);
registerReceiver(mPairingReceiver, filter);
private final BroadcastReceiver mPairingReceiver = new BroadcastReceiver() {
@Override
public void onReceive(Context context, Intent intent) {
final String action = intent.getAction();
if (action.equals(BluetoothDevice.ACTION_BOND_STATE_CHANGED)) {
BluetoothDevice mDevice = intent.getParcelableExtra(BluetoothDevice.EXTRA_DEVICE);
//3 cases:
//case1: bonded already
if (mDevice.getBondState() == BluetoothDevice.BOND_BONDED) {
Log.d(TAG, "BroadcastReceiver: BOND_BONDED.");
Log.e(TAG, "BroadcastReceiver: BOND_BONDED." + mDevice.getName());
mBluetoothAdapter.cancelDiscovery();
}
//case2: creating a bone
if (mDevice.getBondState() == BluetoothDevice.BOND_BONDING) {
Log.d(TAG, "BroadcastReceiver: BOND_BONDING.");
Log.e(TAG, "BroadcastReceiver: BOND_BONDING." + mDevice.getName());
}
//case3: breaking a bond
if (mDevice.getBondState() == BluetoothDevice.BOND_NONE) {
Log.d(TAG, "BroadcastReceiver: BOND_NONE.");
Log.e(TAG, "BroadcastReceiver: BOND_NONE." + mDevice.getName());
}
}
}
};
最后,當您想與設備調用配對時:
mNearbyDeviceRecAdapter.getItemAtPosition(position).getmBluetoothDevice().createBond();
調用此語句后,它將啟動與設備的配對。
希望! 這會有所幫助。
