hi, i would want to programm the end device to communicate with the access point and then display it in the GUI.
lets say i would like to programm the end device with a number 88. when i plug in the end device the number 88 would then be display it in the GUI on the end device node.
would appreciate if anybody here would enlighten me about this? please help. thanks

I assume the GUI you are referencing is a part of the Sensor Monitor demo. Unfortunately the source is not provided for that GUI, but a similar one, with source, is provided with the MSP430 Solar Energy Harvesting Development Tool.
This would need to be modified to display additional information that the eZ430-RF2500 acting as the Access Point would send over the Virtual COM port. The eZ430-RF2500 Access Point needs to be modified to send this additional information to the PC running the GUI.

Programming the End Device with a number, like 88, as an identifier should be straightforward. The End Device application code would then need to be modified to send this information to the AP via a message which you need to construct.
Secondly, the AP software needs to take this message and then send it over the serial interface which ends up on the Virtual COM port.

You might be able to get away with this by adding an additional couple of bytes to the existing message which is sent by the ED to the AP which is the value 0x88.
thanks for the reply Brandon. but could you kindly guide me with it? as i am lost about the source code. i am not really sure which is the code that send the data from the ED to the AP and then to display on the GUI.

First, I assume you are indeed talking about using the SimpliciTI stack and further more using the Wireless Sensor demo (SLAC139) found on the eZ430-RF2500 Product Folder. If so, I would suggest you reference the SimpliciTI API.pdf file found in the documentation directory of the SimpliciTI software installation.
In addition, there is a document discussing the specification of SimpliciTI which helps articulate the functionality of the protocol stack.
The SimpliciTI API document would be the primary document to help understand the calls into the SimpliciTI stack for accomplishing what you are wanting to do. You will then see these calls made in the Wireless Sensor demo application software in both the demo_ED.c and demo_AP.c source files.
In the demo_ED.c, you will see this is the primary file for the sample application using SimpliciTI. You should find 4 calls into the SimpliciTI stack which setup configuration via the SMPL_ioctl(), initialize the stack via SMPL_Init(), linking to the network via SMPL_Link() and finally periodically sending data to the AP via SMPL_Send().
You will also find similiar structure on the demo_AP.c side for the Access Point. This code is a little bit more involved as it sends data to the PC via the Virtual Console port in addition to receiving packets via SMPL_Receive().
thanks brandon. but OMG!!!!!!!!!!!!!!!!! ITS SO HARD TO UNDERSTAND....... =X
Devora said:brandon. a question. how does the GUI (Wireless Sensor demo, i had made certain change to that already) recieve data from the AP?
The demo_AP.c file can be reviewed to understand the packet structure sent to the PC via the Virtual COM port. The GUI interacts with this Virtual COM Port to receive and display the information.
At the end of main(), you will see the call to SMPL_Receive(), which gets the message sent from the ED. The transmitData() function takes this message and sends this in a string to the PC.
hi brandon. i had made some changed to the AP. but now the PC GUI doesnt even display the info when i plug in the AP. the highlighted is the things i add in. can you please help me? thanks =)

You should be able to see these messages printed out on HyperTerminal connected to the Virtual COM Port. Do not invoke the PC GUI, but HyperTerminal instead.
Are the messages formatted the way you expect them to?
Have you recompiled the PC GUI to accept this new formated data coming over the Virtual COM Port?
Hi Brandon. theres seems to have some problems with the sending of message form ED to AP. i tried using PuTTY to see the Virtual Com Port.

Are you using the existing, provided GUI, or a modified version of it?
If you change the packet structure sent by the AP to the PC, you will need to correspondingly modify the PC GUI to accept and parse this new packet. In addition, the code associate with the node class needs to be modified to add this additional parameter and draw it on the actual visual portion of the GUI.
a modify version of my own, i had also changed the packet structure in the iohandler.cpp on the PC GUI as below:
IoHandler::IoHandler(QObject *pParent)
{
pMyParent = (QMainWindow *)pParent;
RefreshComPort();
//conWindow=new ConWindow;
//conWindow->show();
comPort = new ComPort(this);
connect(this, SIGNAL(dataReceived(/*int index*/)), pParent, SLOT(dataReceived(/*int index*/)));
// Create instance to Node Database.
pNodeDb = new NodeDb;
id_node = new QByteArray("Node:");
id_temperature= new QByteArray("Temp:");
id_voltage = new QByteArray("Battery:");
id_strength = new QByteArray("Strength:");
id_EOP = new QByteArray("RE:");
id_anumber = new QByteArray("Anumber:");
}
void IoHandler::handleData(QByteArray *pPacket)
{
NodeDb::DATA *pData = new NodeDb::DATA;
int position, sizeOfIdentifier,i;
// Array to save the value which will be converted
QByteArray temporary("");
// securety to see if the array received is empty or do not contain end of packet
if(pPacket->isNull() ||!(pPacket->contains(*id_anumber))){
// We do not want to start messing with an emtpy or incomplete message
return;
}
position = pPacket->indexOf(*id_node);
sizeOfIdentifier = id_node->size();
if (position == -1) {
// Bad things can happen if "Node:" is not found in the message...
return;
}
// Base node
else if(pPacket->at(position + sizeOfIdentifier + 2) == 'B'){
pData->addr = 0x0000;
pData->type = Node::ACCESS_POINT;
}
// Other node
else {
// The node number is found here, see function description
temporary.append(pPacket->at(position + sizeOfIdentifier + 2));
temporary.append(pPacket->at(position + sizeOfIdentifier + 3));
pData->addr = temporary.toInt();
temporary.clear();
pData->type = Node::END_DEVICE;
}
pData->status = NodeDb::DS_UPDATED;
// Find and add the temperature
position = pPacket->indexOf(*id_temperature);
if (position == -1) {
// Bad things can happen if "Temp:" is not found in the message...
return;
}
sizeOfIdentifier = id_temperature->size();
temporary.append(pPacket->at(position + sizeOfIdentifier));
temporary.append(pPacket->at(position + sizeOfIdentifier + 1));
temporary.append(pPacket->at(position + sizeOfIdentifier + 2));
temporary.append(pPacket->at(position + sizeOfIdentifier + 3));
temporary.append(pPacket->at(position + sizeOfIdentifier + 4));
// Trimmed to remove space at start if the temperature is below 100.0F
temporary.trimmed();
pData->temp = temporary.toFloat();
// Cleared so voltage can be added
temporary.clear();
// Find and add voltage data
position = pPacket->indexOf(*id_voltage);
if (position == -1) {
// Bad things can happen if "Battery:" is not found in the message...
return;
}
sizeOfIdentifier = id_voltage->size();
temporary.append(pPacket->at(position + sizeOfIdentifier));
temporary.append(pPacket->at(position + sizeOfIdentifier + 1));
temporary.append(pPacket->at(position + sizeOfIdentifier + 2));

temporary.append(pPacket->at(position + sizeOfIdentifier +3));
temporary.append(pPacket->at(position + sizeOfIdentifier + 4));
temporary.append(pPacket->at(position + sizeOfIdentifier + 5));
temporary.append(pPacket->at(position + sizeOfIdentifier + 6));
pData->t_time_on=temporary.toInt();
// Cleared so anumber can be added
temporary.clear();
// Find and add anumber data
position = pPacket->indexOf(*id_anumber);
if (position == -1) {
// Bad things can happen if "anumber: " is not found in the message...
return;
}
sizeOfIdentifier = id_anumber->size();
temporary.append(pPacket->at(position + sizeOfIdentifier));
temporary.append(pPacket->at(position + sizeOfIdentifier + 1));
pData->anumber = temporary.toInt();
// time stamp for console information
QDate date = QDate::currentDate();
QString cur_date;
cur_date.sprintf( "%2d/%2d/%4d", date.month(), date.day(),date.year());
QString qsTemp;
qsTemp = QTime::currentTime().toString();
pack_len=ComPortThread::PACKET_LENGTH;
for (i=0;i<pack_len;i++)
{
conTemp.append(pPacket->at(i));
}
conTemp.append(", ");
conTemp.append(cur_date);
conTemp.append(", ");
conTemp.append(qsTemp);
emit storeData(conTemp);
conTemp="";
// for test
if (pData->type == Node::END_DEVICE)
{
rebyte2=temporary.toInt();
pData->fadeNumber=0;
pData->fadeTime=0;
pData->newNode=1;
pData->deletedNode=0;
}
int index;
index = pNodeDb->addData(pData);
emit dataReceived();
}
But it seems like the GUI is not getting the data from AP, the GUI just doesnt work even when i plug in the AP to the USB.
Hi.
Found one thing that you will need to change. In comportthread.h you will need to extend the PACKET_LENGTH to the new string size, otherwise it will not capture the whole string.
Hope this gets you at least a step further.
