Basic Usage

Applications

Simple example that initialises an application client from environment variables, connects, sends 1 command to a device, and then disconnects.

import com.google.gson.JsonObject;
import com.ibm.wiotp.sdk.app.ApplicationClient;

class simpleTest {
    public static void main(String[] args) {
        ApplicationClient appClient = new ApplicationClient();
        appClient.registerCodec(new JsonCodec());
        appClient.connect();
        JsonObject data = new JsonObject();
        data.addProperty("distance", 10);
        appClient.publishCommand("myDeviceType", "myDeviceId", "mycommand", data);
        appClient.disconnect();
    }
}

Devices

Simple example that initialises a device client from environment variables, connects, sends 1 event, and then disconnects.

import com.google.gson.JsonObject;
import com.ibm.wiotp.sdk.app.DeviceClient;

class simpleTest {
    public static void main(String[] args) {
        DeviceClient deviceClient = new DeviceClient();
        deviceClient.registerCodec(new JsonCodec());
        deviceClient.connect();
        JsonObject data = new JsonObject();
        data.addProperty("distance", 10);
        deviceClient.publishEvent("myevent", data);
        deviceClient.disconnect();
    }
