IoT Hub device SDK for Java relies on a secure and powerful data channel to enable IoT developers to quickly connect devices to the cloud for two-way communication. You only need to complete the corresponding project configuration to connect devices.

Prerequisites

Products and devices have been created as instructed in Device Connection Preparations.

How to Import

If you need to use JAR import for project development, you can add dependencies in build.gradle in the module directory as follows:
dependencies {
  ...
  implementation 'com.tencent.iot.hub:hub-device-java:x.x.x'
}
Note:
You can set the above x.x.x to the latest version according to SDK for Java Release Notes.
If you need to develop a project through code integration, you can download the SDK for Java source code from GitHub.

Connection Authentication

Two device authentication methods are supported: key authentication and certificate authentication.
Key authentication requires ProductID, DevName, and DevPSK.
Certificate authentication requires ProductID, CertFile, and PrivateKeyFile.
Below is the sample code for connection authentication:
private String mProductID = "YOUR_PRODUCT_ID";
private String mDevName = "YOUR_DEVICE_NAME";
private String mDevPSK = "YOUR_DEV_PSK";
private String mCertFilePath = null;
private String mPrivKeyFilePath = null;
TXMqttConnection mqttconnection = new TXMqttConnection(mProductID, mDevName, mDevPSK, new callBack());
mqttconnection.connect(options, null);
try {
        Thread.sleep(20000);
} catch (InterruptedException e) {
    // TODO Auto-generated catch block
    e.printStackTrace();
}
mqttconnection.disConnect(null);
