ここにちょっとしたことがあると、あなたの助けが必要になるかもしれません。私は一度にいくつかのBLE特性を読んでみたいと思っています。そのためにPriorityQueueを使用することをお勧めします。私はすでにすべてのuuidsなどが一度にいくつかの方法を読む必要があることを知っている。 誰もそれがどのように正確に見えるべきか説明できますか?それとももっと簡単な解決法がありますか?事前にAndroid複数のBLE特性をPriorityQueueで読み取る方法
おかげで、ここに私のコードです:
public static final BluetoothGattCallback mGattCallback = new BluetoothGattCallback() {
PriorityQueue<BluetoothGattCharacteristic> queue = new PriorityQueue<BluetoothGattCharacteristic>();
// When connection state changes
@Override
public void onConnectionStateChange(BluetoothGatt gatt, int status, int newState) {
if (newState == BluetoothProfile.STATE_CONNECTED) {
Log.v(TAG, "Connected!");
gatt.discoverServices();
}
if (newState == BluetoothProfile.STATE_DISCONNECTED) {
Log.v(TAG, "Disconnected...");
}
}
@Override
public void onServicesDiscovered(BluetoothGatt gatt, int status) {
List<BluetoothGattService> services = gatt.getServices();
BluetoothGattService rightService = null;
for (int i = 0; i < services.size(); i++) {
if (services.get(i).getCharacteristics().size() > 8) {
rightService = services.get(i);
}
}
List<UUID> uuidsList;
UUID TRANSMISSION_POWER = rightService.getCharacteristics().get(4).getUuid();
UUID BROADCASTING_INTERVAL = rightService.getCharacteristics().get(6).getUuid();
UUID BEACON_NAME = rightService.getCharacteristics().get(8).getUuid();
UUID CONNECTION_MODE = rightService.getCharacteristics().get(9).getUuid();
//UUID SOFT_REBOOT = rightService.getCharacteristics().get(10).getUuid();
uuidsList = new ArrayList<UUID>();
uuidsList.add(TRANSMISSION_POWER);
uuidsList.add(BROADCASTING_INTERVAL);
uuidsList.add(BEACON_NAME);
uuidsList.add(CONNECTION_MODE);
//uuidsList.add(SOFT_REBOOT);
queue.add(rightService.getCharacteristic(uuidsList.get(0)));
queue.add(rightService.getCharacteristic(uuidsList.get(1)));
queue.add(rightService.getCharacteristic(uuidsList.get(2)));
}
@Override
public void onCharacteristicRead(BluetoothGatt gatt, BluetoothGattCharacteristic characteristic, int status) {
Log.v(TAG, "CHARACTERISTIC VALUE___: " + characteristic.getIntValue(BluetoothGattCharacteristic.FORMAT_UINT8, 0));
onServicesDiscovered(gatt, 0);
}
};
UPDATE:
も、それはまだ一つだけgatt.readCharacteristic(...)に反応する異なるスレッド上でそれらを入れた後。次のように:
// Gatt Callback
public static final BluetoothGattCallback mGattCallback = new BluetoothGattCallback() {
// When connection state changes
@Override
public void onConnectionStateChange(BluetoothGatt gatt, int status, int newState) {
if (newState == BluetoothProfile.STATE_CONNECTED) {
Log.v(TAG, "Connected!");
gatt.discoverServices();
}
if (newState == BluetoothProfile.STATE_DISCONNECTED) {
Log.v(TAG, "Disconnected...");
}
}
@Override
public void onServicesDiscovered(BluetoothGatt gatt, int status) {
List<BluetoothGattService> services = gatt.getServices();
/*
DISPLAY ALL SERVICES AND CHARACTERISTICS
for (int i = 0; i < services.size(); i++) {
Log.v(TAG, "SERVICE____: " + services.get(i).getUuid());
for (int k = 0; k < services.get(i).getCharacteristics().size(); k++) {
Log.v(TAG, "CHARACTERISTIC____: " + services.get(i).getCharacteristics().get(k).getUuid());
}
}
*/
BluetoothGattService rightService = null;
for (int i = 0; i < services.size(); i++) {
if (services.get(i).getCharacteristics().size() > 8) {
rightService = services.get(i);
}
}
List<UUID> uuidsList;
UUID TRANSMISSION_POWER = rightService.getCharacteristics().get(4).getUuid();
UUID BROADCASTING_INTERVAL = rightService.getCharacteristics().get(6).getUuid();
UUID BEACON_NAME = rightService.getCharacteristics().get(8).getUuid();
UUID CONNECTION_MODE = rightService.getCharacteristics().get(9).getUuid();
//UUID SOFT_REBOOT = rightService.getCharacteristics().get(10).getUuid();
uuidsList = new ArrayList<UUID>();
uuidsList.add(TRANSMISSION_POWER);
uuidsList.add(BROADCASTING_INTERVAL);
uuidsList.add(BEACON_NAME);

//uuidsList.add(SOFT_REBOOT);

}
@Override
