プロジェクトで android.bluetooth パッケージを使用しましたが、読み取りと書き込みの特性のために IBluetoothGatt を実装しようとしています。しかし、私は以下のようないくつかの問題を抱えています
public final class BluetoothGatt implements BluetoothProfile {
private static final String TAG = "BluetoothGatt";
private static final boolean DBG = true;
private static final boolean VDBG = false;
private IBluetoothGatt mService; // IBluetoothGatt red highlights. Some functions in IBluetoothGatt interface just work by put breakpoints.
private BluetoothGattCallback mCallback;
private int mClientIf;
private boolean mAuthRetry = false;
private BluetoothDevice mDevice;
private boolean mAutoConnect;
private int mConnState;
private final Object mStateLock = new Object();
private Boolean mDeviceBusy = false;
private int mTransport;
private static final int CONN_STATE_IDLE = 0;
private static final int CONN_STATE_CONNECTING = 1;
private static final int CONN_STATE_CONNECTED = 2;
private static final int CONN_STATE_DISCONNECTING = 3;
private static final int CONN_STATE_CLOSED = 4;
private List<BluetoothGattService> mServices;
writeIBluetoothGatt インターフェイスの特徴的な赤いハイライト
public void onCharacteristicWrite(String address, int status, int handle) {
if (VDBG) Log.d(TAG, "onCharacteristicWrite() - Device=" + address
+ " handle=" + handle + " Status=" + status);
if (!address.equals(mDevice.getAddress())) {
return;
}
synchronized(mDeviceBusy) {
mDeviceBusy = false;
}
BluetoothGattCharacteristic characteristic = getCharacteristicById(mDevice, handle);
if (characteristic == null) return;
if ((status == GATT_INSUFFICIENT_AUTHENTICATION
|| status == GATT_INSUFFICIENT_ENCRYPTION)
&& mAuthRetry == false) {
try {
mAuthRetry = true;
mService.writeCharacteristic(mClientIf, address, handle,
characteristic.getWriteType(), AUTHENTICATION_MITM,
characteristic.getValue());
return;
} catch (RemoteException e) {
Log.e(TAG,"",e);
}
}
