The communcation is ok in my app. I communicate with the meter using BT probe

Wich functions must I call to decrypt the response of the DLMS meter ?
For example to decrypt the register 1

Hi,

You create an object like this:
GXDLMSRegister reg = new GXDLMSRegister("LOGICAL_NAME");
//Read scaler and unit.
readObject(reg, 3);
//Read value.
readObject(reg, 2);
Objec value = reg.getValue();
You can find readObject from GXMain.java.

Thanks.

In my developer tool(Windev mobile), I must integrate a jar or aar file. I can't directly integrate java file.

I dont't see any jar file into you library. Do you have one ?

Hi,

You need to compile android lib or add this to dependencies:

implementation 'com.github.gurux:gurux.dlms.android:-SNAPSHOT'

Hey Mikko! I've added the dependency you point out in the comment above into build.gradle file on a new Empty Activity Project (Android Studio) like this:

plugins {
id 'com.android.application'
}

android {
compileSdk 30

defaultConfig {
applicationId "com.example.myapplication"
minSdk 21
targetSdk 30
versionCode 1
versionName "1.0"

testInstrumentationRunner "androidx.test.runner.AndroidJUnitRunner"
}

buildTypes {
release {
minifyEnabled false
proguardFiles getDefaultProguardFile('proguard-android-optimize.txt'), 'proguard-rules.pro'
}
}
compileOptions {
sourceCompatibility JavaVersion.VERSION_1_8
targetCompatibility JavaVersion.VERSION_1_8
}
}

dependencies {

implementation 'androidx.appcompat:appcompat:1.2.0'
implementation 'com.google.android.material:material:1.3.0'
implementation 'androidx.constraintlayout:constraintlayout:2.0.4'
implementation 'com.github.gurux:gurux.dlms.android:-SNAPSHOT'

testImplementation 'junit:junit:4.+'
androidTestImplementation 'androidx.test.ext:junit:1.1.2'
androidTestImplementation 'androidx.test.espresso:espresso-core:3.3.0'
}

but when I try to sync I get the following message: "Failed to resolve: com.github.gurux:gurux.dlms.android:-SNAPSHOT".

- The version of Android Studio I am using is 2020.3.1 Patch 3 (SDK 21, Android 5.0 +) and the version of Gradle is 7.0.2 -

Am I doing something wrong?

Thanks,
Nico.
