要解决安卓蓝牙堆栈与BLE设备随机断开连接的问题,可以尝试以下几种方法:
BluetoothAdapter bluetoothAdapter = BluetoothAdapter.getDefaultAdapter();
BluetoothLeScanner bluetoothLeScanner = bluetoothAdapter.getBluetoothLeScanner();
ScanSettings scanSettings = new ScanSettings.Builder()
.setScanMode(ScanSettings.SCAN_MODE_LOW_LATENCY)
.setReportDelay(0)
.build();
List scanFilters = new ArrayList<>();
bluetoothLeScanner.startScan(scanFilters, scanSettings, scanCallback);
private BluetoothGattCallback gattCallback = new BluetoothGattCallback() {
@Override
public void onConnectionStateChange(BluetoothGatt gatt, int status, int newState) {
if (newState == BluetoothProfile.STATE_CONNECTED) {
// 已连接
} else if (newState == BluetoothProfile.STATE_DISCONNECTED) {
// 断开连接
// 进行重连或其他处理
}
}
};
private static final long CONNECTION_TIMEOUT = 10000; // 10秒
private void connectToDevice(BluetoothDevice device) {
BluetoothGatt gatt = device.connectGatt(context, false, gattCallback);
// 设置连接超时
new Handler().postDelayed(() -> {
if (gatt != null && gatt.getDevice().equals(device)) {
gatt.disconnect();
// 进行重连或其他处理
}
}, CONNECTION_TIMEOUT);
}
这些方法可以帮助你解决安卓蓝牙堆栈与BLE设备随机断开连接的问题。根据具体情况选择适合的方法进行尝试。
