Overview

A class to hold and define the information in an ANT wireless data payload.

Example:

using Toybox.Ant;
// Wrap the message prep and broadcast in a callback method
function onMessage(msg) {
    var payload = msg.getPayload(); //get the data payload
    var data = new [msg.length];    // create an array the length of the message

    // Iterate and add data to the Message with each pass
    for (var i = 0; i < msg.length; i++) {
        data[i] = i;            // Adds {0,1,2,3,4,5,6,7}
    }

    var message = new Ant.Message();
    message.setPayload(data);       // Form the Message

    // Set the broadcast buffer
    genericChannel.sendBroadcast(message);
}
