蓝牙没有读取每个特征

Question

我在我的应用程序中遇到了蓝牙问题。我有很多特征，只能读取2.当我尝试阅读更多时，我没有得到任何回调。我读到我应该创建队列，但不知道如何去做。请帮忙吗？

这是我的特点：

private void registerParametersCharacteristics(List<BluetoothGattCharacteristic> characteristics) { 
     for (BluetoothGattCharacteristic characteristic : characteristics) { 
      UUID characteristicUuid = characteristic.getUuid(); 
      if (Characteristics.EON_PARAMS_EDDYSTONE_UID_CHAR.equals(characteristicUuid)) { 
       euidCharacteristic = characteristic; 
       Log.e(TAG, "registerParametersCharacteristics: EUID"); 
      } 
      else if (Characteristics.EON_PARAMS_EDDYSTONE_EID_CHAR.equals(characteristicUuid)) { 
       eeidCharacteristic = characteristic;} 
      else if (Characteristics.EON_PARAMS_EDDYSTONE_URL_CHAR.equals(characteristicUuid)) { 
       eurlCharacteristic = characteristic;} 
      else if (Characteristics.EON_PARAMS_EDDYSTONE_TLM_CHAR.equals(characteristicUuid)) { 
       etlmCharacteristic = characteristic;} 
      else if (Characteristics.EON_PARAMS_EDDYSTONE_UID_UUID.equals(characteristicUuid)) { 
       eUidUUidCharacteristic = characteristic;} 
      else if (Characteristics.EON_PARAMS_EDDYSTONE_URL_UUID.equals(characteristicUuid)) { 
       eUrlUuidCharacteristic = characteristic; 
       Log.e(TAG, "registerParametersCharacteristics: EurlUUID"); 
      } 
      else if (Characteristics.MINOR_CHARACTERISTIC_UUID.equals(characteristicUuid)) { 
       minorCharacteristic = characteristic;} 
      else if (Characteristics.MAJOR_CHARACTERISTIC_UUID.equals(characteristicUuid)) { 
       majorCharacteristic = characteristic; 
      } 
      else if (Characteristics.UUID_CHARACTERISTIC_UUID.equals(characteristicUuid)){ 
       uuidCharacteristic = characteristic; 
      } 
      else if (Characteristics.INTERVAL_CHARACTERISTIC_UUID.equals(characteristicUuid)) { 
       intervalCharacteristic = characteristic; 
      } 
      else if (Characteristics.TX_CHARACTERISTIC_UUID.equals(characteristicUuid)) { 
       txCharacteristic = characteristic; 
      } 
      else if (Characteristics.BATTERY_CHARACTERISTIC_UUID.equals(characteristicUuid)) { 
       batteryCharacteristic = characteristic; 
       Log.e(TAG, "registerParametersCharacteristics: BAT"); 
      } 
      Log.e(TAG, "registerParametersCharacteristics: " + characteristic.getUuid().toString()); 
     } 
    } 

，这是我onServicediscovered方法：

@Override 
     public void onServicesDiscovered(BluetoothGatt gatt, int status) { 
      super.onServicesDiscovered(gatt, status); 
      if (status == BluetoothGatt.GATT_SUCCESS) { 
       List<BluetoothGattService> services = gatt.getServices(); 
       for (BluetoothGattService service : services) { 
        registerService(service); 
        Log.e(TAG, "onServicesDiscovered: " + service.getUuid().toString()); 
       } 
       callback.connectedStateChanged(true); 
      } else 
       disconnect(); 
     } 
     @Override 
     public void onCharacteristicRead(BluetoothGatt gatt, BluetoothGattCharacteristic characteristic, int status) { 
      super.onCharacteristicRead(gatt, characteristic, status); 
      characteristicValueRead(characteristic); 
      BluetoothCommunicationManager.getInstance().processNext(); 
     } 

我失去了两天写这个队列，并不能做到这一点。在此先感谢您的帮助。

你应该使用'command'设计模式。基本上，你将拥有抽象的类或接口与单个“执行（..）”方法。您将创建类，扩展'Command'类，但是每个实现都将完成自己的工作。 然后您可以创建“ArrayList的”，添加所有任务，把它和处理在“for”循环像那些任务：

for (Command c : commands){ 
c.execute(..); 
{
