# Eclipse Kapua™ Gateway Client SDK [![Build status](https://api.travis-ci.org/ctron/kapua-gateway-client.svg)](https://travis-ci.org/ctron/kapua-gateway-client) [![Maven Central](https://img.shields.io/maven-central/v/de.dentrassi.kapua/kapua-gateway-client.svg "Maven Central Status")](https://search.maven.org/#search%7Cga%7C1%7Cg%3A%22de.dentrassi.kapua%22)

This project provides an SDK for connecting to [Eclipse Kapua](https://eclipse.org/kapua) as a gateway.

**Note:** This is not part of the Eclipse Kapua project.

This project should provide a simple to use SDK for pushing telemetry data into Kapua

and consuming command messages out of Kapua.

**Note:** This is a work in progress and should not be considered production ready.

## How to use

The following quick steps should provide you with a working example.

### Add to your Maven project

```xml

  de.dentrassi.kapua

  kapua-gateway-client-provider-mqtt-fuse

  

  de.dentrassi.kapua

  kapua-gateway-client-profile-kura

  

```

### Example client

```java

import static org.eclipse.kapua.gateway.client.Credentials.userAndPassword;

import static org.eclipse.kapua.gateway.client.Errors.ignore;

import org.eclipse.kapua.gateway.client.mqtt.fuse.FuseClient;

import org.eclipse.kapua.gateway.client.profile.kura.KuraMqttProfile;

try (Client client = KuraMqttProfile.newProfile(FuseClient.Builder::new)

  .accountName("kapua-sys")

  .clientId("foo-bar-1")

  .brokerUrl("tcp://localhost:1883")

  .credentials(userAndPassword("kapua-broker", "kapua-password"))

  .build()) {

  try (Application application = client.buildApplication("app1").build()) {

    // subscribe to a topic

    application.data(Topic.of("my", "receiver")).subscribe(message -> {

      System.out.format("Received: %s%n", message);

    });

    // cache sender instance

    Sender sender = application

      .data(Topic.of("my", "sender"))

      .errors(ignore());

    int i = 0;

    while (true) {

      // send

      sender.send(Payload.of("counter", i++));

      Thread.sleep(1000);

    }

  }

}

```
