Hi to do this i had to create and use Wearable.MessageApi using GoogleApiClient

I have complete code posted on Git repo : --> https://github.com/mvyas85/Fall-Alarm-Wearable

Since Wearable can only make bluetooth connection with Phone, main method to send msg is using following class which is a thread and which uses Wearable.MessageApi to send msg from my Android wearable to my phone. and then phone has Socket which on Wifi connects to Server.

```
/**
 * WearableMessageSender is responsible for sending messages
 * between apps and wearable devices. It manages this work
 * on its own thread.
 */
public class WearableMessageSender extends Thread {

private static final String TAG = "WearableMessageSender";

private String mPath;
    private DeviceData mMessage;
    private GoogleApiClient mGoogleApiClient;
    /**
     * Constructor to send a message to the data layer
     * @param path Message path
     * @param msg Message contents
     * @param googleApiClient GoogleApiClient object
     */
    public WearableMessageSender(String path, DeviceData msg, GoogleApiClient googleApiClient) {
a
        Log.i(TAG,"Google Api is connected");
        if (null == path || null == msg || null == googleApiClient) {
            Log.e(TAG, "Invalid parameter(s) passed to WearableMessageSender");
            throw new IllegalArgumentException("Invalid parameter(s) passed to WearableMessageSender");
        }
        mPath = path;
        mMessage = msg;
        mGoogleApiClient = googleApiClient;
    }

public void run() {
        // Broadcast message to call connected nodes
        NodeApi.GetConnectedNodesResult nodes = Wearable.NodeApi.getConnectedNodes(mGoogleApiClient).await();
        for (Node node : nodes.getNodes()) {
            MessageApi.SendMessageResult result = null;
            try {
                result = Wearable.MessageApi.sendMessage(
                        mGoogleApiClient,
                        node.getId(),
                        mPath,
                        DeviceData.serialize(mMessage)
                ).await();
                Log.i(TAG,"Trying to send byte arr::"+DeviceData.serialize(mMessage));
            } catch (IOException e) {
                e.printStackTrace();
            }

if (result.getStatus().isSuccess()) {
                Log.d(TAG, "Message: {" + mMessage + "} successfully sent to: " + node.getDisplayName());
            } else {
                Log.e(TAG, "Failed to send message to device");
            }
        }
    }
}
```
