我正在使用以下反应库react-native-ble-manager

我试图在BLE设备上执行读写操作.我成功地执行了读操作.但是在写入BLE设备时我收到错误代码128.

首先,我正在启用特征通知 -

BleManager.startNotification(peripheralId, serviceId, characteristicId)

写是这样的 -
将'hex'值转换为base64字符串 -

  const base64String = new Buffer('0x00B00050D0', 'hex').toString('base64');

  BleManager.write(peripheralId, serviceId, characteristicId, base64Value)

写操作返回错误代码-128

:(

UPDATE - 这是用于启动通知和写入值的代码片段 - 完整文件可在此处找到 - BluetoothLeService.java

public void writeCharacteristic(BleCharacteristic bleCharacteristic, String inputValue) {

    if (mBluetoothAdapter == null || mBluetoothGatt == null) {
        Log.w(TAG, "BluetoothAdapter not initialized");
        return;
    }

    if (!bleCharacteristic.isNotificationStarted()) {
        Log.w(TAG, "Notification not started please start notification");
        return;
    }

    BluetoothGattCharacteristic bluetoothGattCharacteristic = bleCharacteristic.getBluetoothGattCharacteristic();
    bluetoothGattCharacteristic.setValue(inputValue);
    mBluetoothGatt.writeCharacteristic(bluetoothGattCharacteristic);
}

public void setCharacteristicNotification(BleCharacteristic bleCharacteristic) {
    if (mBluetoothAdapter == …

我正在使用hibernate4和spring 3和jsf2.0进行注入我使用注释我在Google上搜索了这个例外,但是在这里找不到任何合适的解决方案我发布了我的日志,应用程序上下文和dao实现

Here is my logs

我正在使用带有gradle构建工具的android studio.我正在尝试使用RoboGuice进行依赖注入.这是我的builde.gradle混淆

   buildscript {
    repositories {
        mavenCentral()
        maven { url 'http://repo1.maven.org/maven2' }

    }
    dependencies {
        classpath 'com.android.tools.build:gradle:0.5.+'
    }
}

    apply plugin: 'android'

    repositories{
    mavenCentral()
}


    android {
    compileSdkVersion 17
    buildToolsVersion "17.0.0"

    defaultConfig {
        minSdkVersion 11
        targetSdkVersion 16
    }
}

    dependencies {
    compile 'com.android.support:support-v4:13.0.0'
    compile 'org.roboguice:roboguice:2.0'
    compile 'com.google.inject:guice:3.0'
    compile 'com.google.code.findbugs:jsr305:1.3.9'
    compile 'com.j256.ormlite:ormlite-android:4.46'
    compile 'com.j256.ormlite:ormlite-core:4.46'
}

这些是我尝试构建时的日志
