If you want larger payload you must use advanced burst data.</p> <p>With extended messages, the normal data type messages (broadcast/acknowledge/burst) can be extended to allow ANT to pass additional information to the host, along with the received data message. This extended information is not sent over the air, it is information that is containted in the stack, like channel ID, RSSI, Timestamp, and so on.</p><div style="clear:both;"></div>
