Mqtt connection failed with exception 'Not authorized to connect (5)' android

Hi I am trying to connect to mqtt with my android device that I just registered but it I keep getting the error 

Not authorized to connect (5)

This is some of my code

        client = new MqttAndroidClient(context, connectionURI, clientID);
        client.setCallback(callbacks);

        String username = IOT_DEVICE_USERNAME;
        char[] password = this.getAuthorizationToken().toCharArray();

        MqttConnectOptions options = new MqttConnectOptions();
        options.setCleanSession(true);
        options.setUserName(username);
        options.setPassword(password);

        Log.d(TAG, "Connecting to server: " + connectionURI);
        try {
            // connect
            return client.connect(options, context, listener);
        } catch (MqttException e) {
            Log.e(TAG, "Exception caught while attempting to connect to server", e.getCause());
            throw e;
        }

where IOT_DEVICE_USERNAME is a string "use-token-auth" and connectionUri is "tcp://<"organization">.messaging.internetofthings.ibmcloud.com:8883"

Something else that is interesting is that right before this error I get this log 

Unregister alarmreceiver to MqttServiced:<"organisation">:<"DeviceType">:<"deviceId">

Here is the stackTrace of the error

Solution

  • The problem is fixed. I was indeed using this as the client id in as an imput to the constructor of the MqttAndroidClient object.

    String iotClientId = "d:"+ORG+":"+DEVICE_TYPE+":"+DEVICE_ID;

    However, since I regestered the Android device as a gateway because it is actually connecting to multiple peripherals where the sensors actually are. To fix this, I the above line to

    String iotClientId = "g:"+ORG+":"+DEVICE_TYPE+":"+DEVICE_ID;
