Я создаю приложение, которое программно подключается к устройству BLE с приложением Android. Вот мой код для подключения/отключения
Когда пользователь нажимает кнопку «Подключиться»
new Thread(new Runnable() {
@Override
public void run() {
mConnecting = true;
mConnectException = null;
mConnectWait.close(); // Reset the condition.
if (mConnectedGatt != null) {
// Reconnect to the BLE DEX adapter.
Logger.d(LOG_TAG, "going to connect");
mConnectedGatt.connect();
BluetoothDevice device = mBluetoothAdapter.getRemoteDevice(deviceAddress);
device.connectGatt(mContext, false, mGattCallback);
} else {
// Start scanning BLE devices.
Logger.d(LOG_TAG, "going to scan LE Devices");
scanLeDevice(true);
}
mConnectWait.block(); // Wait for connect to complete
try {
if (mConnected) {
connectCallback.onConnectSuccess();
} else { // Error occurred in the connecting process
if (null == mConnectException) {
mConnectException = new BleDexException(
"Failed to connect to the BLE DEX adapter",
BleDexException.ERROR_BLE_CONNECT_FAILED);
}
connectCallback.onConnectFailed(mConnectException);
}
} catch (Exception e) {
e.printStackTrace();
}
mConnecting = false;
}
}).start();
Код сканирования:
if (!mBleScanning) {
// Stops scanning after a pre-defined scan period.
mHandler.postDelayed(new Runnable() {
@Override
public void run() {
mBleScanning = false;
if ((null != mBleScanner) && (mBluetoothAdapter.getState() == BluetoothAdapter.STATE_ON)) {
mBleScanner.stopScan(mScanCallback);
if (mConnecting) {
Logger.e(LOG_TAG, "Timed out in scanning BLE devices");
mConnectException = new BleDexException(
"Timed out in scanning BLE devices",
BleDexException.ERROR_BLE_CONNECT_FAILED);
mConnectWait.open();
}
}
}
}, mBleScanPeriod);
mBleScanning = true;
//ScanFilter scanFilter = new ScanFilter.Builder().setServiceUuid(new ParcelUuid(DEX_SERVICE_SPP)).build();
ScanFilter scanFilter = new ScanFilter.Builder().setDeviceName("DEXAdapter").build();
java.util.ArrayList<ScanFilter> scanFilterList = new java.util.ArrayList<ScanFilter>();
scanFilterList.add(scanFilter);
ScanSettings scanSettings = new ScanSettings.Builder()
.setScanMode(ScanSettings.SCAN_MODE_BALANCED)
.build();
if((null != mBleScanner) && (mBluetoothAdapter.getState() == BluetoothAdapter.STATE_ON))
mBleScanner.startScan(scanFilterList, scanSettings, mScanCallback);
}
} else {
Logger.d(LOG_TAG, "stop scanning. what 's the scan flag is: " + mBleScanning);
if (mBleScanning) {
mBleScanning = false;
if ((null != mBleScanner) && (mBluetoothAdapter.getState() == BluetoothAdapter.STATE_ON))
mBleScanner.stopScan(mScanCallback);
}
}
Это широковещательный приемник для намерения сопряжения
public void onReceive(Context context, Intent intent) {
String action = intent.getAction();
if (BluetoothDevice.ACTION_PAIRING_REQUEST.equals(action)) {
if (mBtPin == null || mBtMacAddress == null) {
return;
}
// Programmatically set the Bluetooth PIN.
device = intent.getParcelableExtra(BluetoothDevice.EXTRA_DEVICE);
pairingRequestType = intent.getIntExtra(BluetoothDevice.EXTRA_PAIRING_VARIANT,
BluetoothDevice.ERROR);
Logger.d(LOG_TAG, "Received pairing request intent, Device mac address is: " + mBtMacAddress +
". Device pairingrequest type is: " + pairingRequestType);
if (device.getAddress().equals(mBtMacAddress)) {
try {
int btpin = Integer.parseInt(mBtPin);
Logger.d(LOG_TAG, "Set pin to BT = " + btpin);
byte[] pinbytes;
pinbytes = ("" + btpin).getBytes("UTF-8");
device.setPin(pinbytes);
abortBroadcast();
} catch (Exception e) {
e.printStackTrace();
}
}
} else if (BluetoothDevice.ACTION_BOND_STATE_CHANGED.equals(action)) {
int state = intent.getIntExtra(BluetoothDevice.EXTRA_BOND_STATE, -1);
switch (state) {
case BluetoothDevice.BOND_NONE:
Logger.d(LOG_TAG, "Remote device is not bonded. Device: ");
case BluetoothDevice.BOND_BONDING:
Logger.d(LOG_TAG, "Remote device is in bonding process");
break;
case BluetoothDevice.BOND_BONDED:
Logger.d(LOG_TAG, "Remote device is paired");
BluetoothDevice bluetoothDevice = mBluetoothAdapter.getRemoteDevice(deviceAddress);
mConnectedGatt = bluetoothDevice.connectGatt(mContext, false, mGattCallback);
if (mConnectedGatt == null) {
Logger.e(LOG_TAG, "Failed to connect to GATT server");
if (mConnecting) {
mConnectException = new BleDexException(
"Failed to connect to GATT server",
BleDexException.ERROR_BLE_CONNECT_FAILED);
mConnectWait.open();
}
}
//scanLeDevice(false);
break;
}
}
}
};
Что происходит, как только я нажимаю кнопку подключения, он проверяет, подключено ли устройство или нет? Если нет, он начнет сканирование Bluetooth LE. Я добавил ScanFilter для сканирования устройства, чтобы он сканировал ограниченное устройство.
Как только приложение получает обратный вызов сканирования, оно связывает устройство с помощью метода createbond(). И как только это будет сделано и сопряжение будет завершено, он попытается подключить bluetooth gatt.
Все это успешно работает с первой попытки. Но через какое-то время приложение автоматически отключает bluetooth-устройство.
Это логи автоматического отключения

Теперь я немного изменил поведение приложения, вместо сопряжения и подключения устройства я напрямую подключаю устройство без сопряжения. С этими изменениями я увидел, что соединение Bluetooth автоматически отключается через 30 секунд соединения. Ниже приведены журналы:
