Problem sending Google map links via SMS

Sun, 28 Mar 2010 13:47:52 -0700

I was wondering if anyone could tell me how to "force" a link from an SMS message to Google Maps to display the entire link. Let me explain with an example. If I send this link via email "http://maps.google.com/maps?q=+42+22.6176,-071+46.5349+(MESSAGE+HEREIN)&iwloc=A&hl=en" it will bring up google maps and display the text bound within the parenthesis in a small popup window like it's supposed too. If I send the exact same link from a cell phone via SMS to an email or another SMS the address does not link the additional info bound within the parenthesis, it also only shows the address underlined up to but not including the first parenthesis. If I take that same email that doesn't work and reforward it back to myself the link works correctly. SO I guess my question is is there any way to force the the link by using any type of tags or formatting characters? Am I missing something here...because I'm totally stumped. Thanks.

communication between mobile phone and server computer

Fri, 14 Aug 2009 23:51:36 -0700

Hello!

I'd like to create such an application that the user of mobile phone can call special service number and would connect by calling this number to the server computer in building about one kilometer from him/her. This is situation if that person has got his/her mobile phone from boss.

In the case if it is private mobile phone, I'd like that person to call the special service number and stop connection just after connecting. Then the server would call back to that person.

The puprose of this connection is to send voice data from employee and save this data as wave file on the server for further analysis.

I thought about using Java language. I would create application for two or three the most popular kinds of mobile phones. (What are those?)

Can you give me any suggestions / inform about useful technologies which I can apply in this solution?

Thanks very much for your help!

Greetings!

Bluetooth connection not working on US Nokia phones from J2ME Midlet (

Tue, 14 Jul 2009 03:01:28 -0700

Hi All,

We are developing a J2ME midlet (MIDP 2.0 ,CLDC 1.1)which makes bluetooth connection to other devices.The bluetooth connection is working perfectly on indian nokia phones with Airtel as carrier.But when we deploy the same midlet on Nokia E71 US phone with carrier as AT&T ,the bluetooth connection is not working.The sample code is as follows:

public void run(){

try{
StreamConnection connection = (StreamConnection)Connector.open(btConnectionURL);

//
// open an input stream to get some data
//

InputStream in = connection.openInputStream();

byte[] serialData;
readData = true;
while(readData == true){
int lengthavai=0;
lengthavai = in.available();

if(lengthavai > 0){

serialData = new byte[lengthavai];
int length = in.read(serialData);

System.out.println("data read: " + new String(serialData));

dataViewForm.append(new String(serialData));
}
}

in.close();
connection.close();

}catch(IOException ioe){
ioe.printStackTrace();
}

when we try to connect on US Phones,the execution hangs at the following line of code:
StreamConnection connection = (StreamConnection)Connector.open(btConnectionURL);

No exception is caught.

Our midlet is not signed.

In the Forums it is said that the problem is with the unsigned midlet.AS some of the US carriers block the secure API usage on Unsigned midlet.

But our question is, if we buy a code signing certificate from Verisign or Thawte and sign the midlet, will this problem be solved.

Any other alternative solutions for this ???

Immediate help will be appreciated.

Thanks,
Mari raja

Re: sms-ing.. how to code?

Mon, 12 Jan 2009 19:45:57 -0700

Let me try and answer your questions.

Do you need to receive SMS? If you need to receive SMS, you will need to host your own GSM device or modem so that people can send you SMS.

If not, you can just use internet SMS gateways like clickatell to do the work, and post to them by HTTP, XML or email. The cost is about 6-8 cents per SMS. There are cheaper services, but not always reliable. If you need to host your own GSM device, you can use software like http://www.kannel.org (GPL Open Source) or http://visualtron.com/enterprise/sms-gateway.

It might be possible, but that would involve breaking and rebuilding the phone processor. Practically it is not possible, because nearly all the electronics are embedded into ic's.

I m new in pocket PC i m using embedded Visual basic (eVB) for developing application for pocket PC. I want to access sql server directly from my pocket PC which is mobiled means there is a internet facility in my pocket PC. I created one server VB application to which i send the SQL query from my pocket PC using winsock control and that server app sends back the result to pocket PC application. This is working fine if my pocket PC is connected to cradle, but if i disconnect my pocket PC from cradle it is not working. Can anybody tell me the solution for this or any other method for accessing SQL server from my Pocket PC .

ad-hoc simulation

Mon, 11 Dec 2006 04:40:14 -0700

Any bids?

----
Ad hoc Simulation Phase I

CSMA/ CA Simulation Problem

Assume that we have a grid of 1Km * 1Km with the following conditions:

Nodes are distributed randomly

Number of nodes = 100

Packet size = 1kB

Ack packet = 2b

Nodes are stationary

Maximum transmission Range = 250m

Propagation Speed = 2 * 108 m/s

Transmission delay is ignored

Simulation time = 2 hours

Calculate the max probability of sending.

-------------------

Ad hoc Simulation Phase II

Assume that we have a grid of 1Km * 1Km with the following conditions:

Nodes are distributed randomly

Packet size = 1kB

Ack packet = 2b

Nodes are mobilizing; the speed is between 0 to 5 m/s

Nodes schedule a new event between 10 to 60 seconds

Maximum transmission Range = 250m

Propagation Speed = 2 * 108 m/s

Nodes are allowed to send to any node in the grid

Assume that each node will have a sufficient battery power till the end of the simulation time

Select an ad hoc routing protocol as discussed in the class (on-demand or cluster-based)

Use the CSMA/CA model that you built in Phase I

Do the performance evaluation for 50, 100, and 200 nodes

Simulation time 2 hours

Calculate the following:

Average waiting time per packet that is the time from the packet is scheduled to be sent till it reaches the destination

Average contention time per packet

Average Throughput

Deadline is 01/01/2007

great idea.. need help

My colleague and I have an awesome idea that has to do with PDAs and wireless internet. We're both freshman in college and don't know much about programming so if anyone is interested in helping us that would be great. We went to a venture capital firm and they literally said that our idea was the shit but said that in order for them to invest in us we would need help from someone with a technical background to ensure that it could be done. if you're willing to help... khodges@ucsc.edu

intelligent system for wireless

Sat, 30 Sep 2006 08:28:22 -0700

I'm trying to find info on if it is possible to build an intelligent system for e-learning on a PDA. My knowledge of PDA's is basic, and all i know is that you can program applications for them in C/C++.

Is there any case based reasoning languages that I can use on a PDA??

Any tips will be much appreciated!
