Learning how to exchange string data with peer agents is a basic SAP management skill:

1. To send a string message to a remote peer agent, use the sendData() method of the SASocket interface with the channel ID:

   /* SAAgent object has been obtained using the requestSAAgent() method */
   var SASocket;
   var connectioncallback = 
   {
      /* Connection between provider and consumer is established */
      onconnect: function(socket) 
      {
         SASocket = socket;
         for (var i = 0; i < SAAgent.channelId.length; i++) 
         {
            SASocket.sendData(SAAgent.channelIds[i], "send message to " + i + "th channel.");
         }
      }
   }
   
   SAAgent.setServiceConnectionListener(connectioncallback);
   

   To send an encrypted string message to a remote accessory peer agent, use the sendSecureData() method instead of the sendData() method:

   SASocket.sendSecureData(SAAgent.channelIds[i], "send message to " + i + "th channel.");
   

2. To receive a string message from a remote peer agent, use the setDataReceiveListener() method. This method registers the SADataReceiveCallback listener interface, which is invoked when a string message from a peer agent is received.

   function onreceive(channelId, data) 
   {
      console.log("Message received - " + channelId + " : " + data); 
   }
   
   SASocket.setDataReceiveListener(onreceive);
