Library for Cayenne Low Power Payload

Download

Step 1. Add the JitPack repository to your build file

Add it in your root settings.gradle at the end of repositories:

	dependencyResolutionManagement {
		repositoriesMode.set(RepositoriesMode.FAIL_ON_PROJECT_REPOS)
		repositories {
			mavenCentral()
			maven { url 'https://jitpack.io' }
		}
	}

Add it in your settings.gradle.kts at the end of repositories:

	dependencyResolutionManagement {
		repositoriesMode.set(RepositoriesMode.FAIL_ON_PROJECT_REPOS)
		repositories {
			mavenCentral()
			maven { url = uri("https://jitpack.io") }
		}
	}

Add to pom.xml

	<repositories>
		<repository>
		    <id>jitpack.io</id>
		    <url>https://jitpack.io</url>
		</repository>
	</repositories>

Add it in your build.sbt at the end of resolvers:

 
    resolvers += "jitpack" at "https://jitpack.io"

Add it in your project.clj at the end of repositories:

 
    :repositories [["jitpack" "https://jitpack.io"]]

Step 2. Add the dependency

	dependencies {
		implementation 'com.github.krishnact:cayenne-lpp:-SNAPSHOT'
	}
	dependencies {
		implementation("com.github.krishnact:cayenne-lpp:-SNAPSHOT")
	}
	<dependency>
	    <groupId>com.github.krishnact</groupId>
	    <artifactId>cayenne-lpp</artifactId>
	    <version>-SNAPSHOT</version>
	</dependency>

                            
    libraryDependencies += "com.github.krishnact" % "cayenne-lpp" % "-SNAPSHOT"
        
        

                            
    :dependencies [[com.github.krishnact/cayenne-lpp "-SNAPSHOT"]]

Readme

cayenne-lpp

Java library for Cayenne Low Power Payload (https://mydevices.com/cayenne/docs/lora/#lora-how-lorawan-works)

Quick Start

Following Groovy code shows how to use the library:

@Grapes([
        @GrabResolver(name='jitpack', root='https://jitpack.io'),
        @Grab ('com.github.krishnact:cayenne-lpp:-SNAPSHOT'),
])
import org.himalay.msgs.runtime.Created;
import org.himalay.msgs.runtime.IntegerHolder;
import org.himalay.lpp.LPPDataFactory;

// Temperature 
byte[] bytes = "03 67 01 10".replaceAll('\\s+',"").decodeHex()
DataInputStream dis = new DataInputStream(new ByteArrayInputStream(bytes));
org.himalay.lpp.LPPDataFactory.LPPData data = LPPDataFactory.createMsg(dis, new IntegerHolder());
data.dump();
println data.getValue()

// Acceleration
bytes = "06 71 04 D2 FB 2E 00 00".replaceAll('\\s+',"").decodeHex()
dis = new DataInputStream(new ByteArrayInputStream(bytes));
data = LPPDataFactory.createMsg(dis, new IntegerHolder());
data.dump();
