How to Turn On SIM900 with arduino.

We were getting some strange behavior out of the SIM900 module.
Some times the module was working ok, and others not so ok. :)

The main problem was in turning on method of the SIM900.

The solution:
Turn off and Then Turn on the SIM900.

The arduino code with the NewSoftSerial:


#define GSM_ON_PIN 8


int AvrHardwareHelper::TurnOffGsm()
{

mySerial.println("AT+CPOWD=1");

delay(3000);
digitalWrite(GSM_ON_PIN, LOW);
delay(2000);
digitalWrite(GSM_ON_PIN, HIGH);
delay(2500);

return atCommandResult;
}

int AvrHardwareHelper::TurnOnGsm(char* pin, int pinSize)
{
mySerial.println("AT+CFUN=1");
delay(600);
mySerial.flush();
mySerial.println("AT");
delay(600);

int numberOfBytesRead = 0;
while((mySerial.read()) > 0)
{
numberOfBytesRead++;
}

if(numberOfBytesRead==0)
{
digitalWrite(GSM_ON_PIN, HIGH);
delay(1200);
digitalWrite(GSM_ON_PIN, LOW);
delay(2500);
}

mySerial.flush();
delay(2000);

.... Do the rest here, at+cpin, etc....
}




pinMode(GSM_ON_PIN, OUTPUT); // sets pin 5 as output
mySerial.begin(9600);
TurnOffGsm();
TurnOnGsm("1234", 4);


This is the main difference with all the samples on the web.
If someone is searching for more info, please just leave a comment.

Arduino sprintf too big for AVR

I have learned the hard way that using the sprintf function on a program running on a AVR will add 2200 bytes into your program size.
The limit i had for my program was of 30000 bytes, so it's too much.

So, don't use it.

Import your contacts from excel to your nokia phone using ovi

Well, it's easy.

Use javascript.

Inject the script, using firebug or something with a javascript console.

The batch is something like this:
document.getElementById('firstName').value = 'me'; document.getElementById('mobile').value = '22222222'; javascript:com.ovi.contacts.quickAddContact();

You can add email and last name.


Step by step:
1.Logon on ovi.com.
2.Go to contacts tab.
3.Use the excel with your contacts
4.Use the following formulas to generate the right commands:
=CONCATENATE("document.getElementById('firstName').value = '";B2;"';")
=CONCATENATE("document.getElementById('mobile').value = '";C2;"';")
javascript:com.ovi.contacts.quickAddContact();

5.Then copy the generated cells, copy it and run it using firebug.
I will put the sample excel.

Cheers,
Moleiro

Carvoeiro Vila Nova

I'm developing a site making use of JQuery combine with asp.net:
Vila Nova - Praia do Carvoeiro

The goal is to create a nice site with some java script with nice menus, date picker and other stuff, but without forgetting the accessibility issue. Well, with JQuery, you can do it all.

It's very easy to do it, check the nice calendar, menu ( yes a asp:menu ) and the image gallery.

Developing the asp:menu was easy, you must make use of adapters, for further reading check the css friendly adapters project: http://www.asp.net/cssadapters/.

If you are looking for one date pickers, try the jquery samples. Check one nice project about using the jquery datepicker in asp.net: http://www.west-wind.com/weblog/posts/213015.aspx

There are still things to work out, like some issues with accessibility, and some other bugs :).

If you want detials, just post a comment a will reply ASAP.

By the way, if you ever came to Portugal, enjoy the wonderfull beach of Carvoeiro, and have a nice meel at the pool on Vila Nova.

Set a Property Value to Null given a tree of objects and the path

 

This code was developed by Snippet Compiler (once again).

These code could be used in other things. The original prupose was to set some properties to null, from a given path to the property as a string.

Email in dev

 

Cool config to save the emails on a folder without the need for a smtp server:

  <system.net>

Ajax Culture Sys.CultureInfo (Ajax em Português)

 

How to change the ajax culture to a new one?

1. Save a copy of MicrosoftAjax.js ( you can find it on System.Web.Extensions thru Reflector tool)

2. Put it in the web server, in my case “/scripts”

3. Duplicate the file and rename it to MicrosoftAjax.PT-pt.js

4. Edit the file MicrosoftAjax.PT-pt.js and do some replace of strings (ex: month names)

5. Edit the ScriptManager (The value “PT-pt” from the ResourcesUICultures attribute is used to get the MicrosoftAjax.PT-pt.js)

<asp:ScriptManager ID="ScriptManager" runat="server" EnableScriptLocalization="true" EnableScriptGlobalization="true">
<Scripts>
    <asp:ScriptReference Name="MicrosoftAjax.js" Path="~/Scripts/MicrosoftAjax.js" ResourceUICultures="PT-pt" />
</Scripts>
</asp:ScriptManager>

and http://msdn.microsoft.com/pt-br/magazine/cc135974.aspx

You are done.

Use Custom Objects in Project Settings

 

1.Add a new setting, set the name and one of displayed types.

2.Inside your VS.Net open the Settings with the Xml Editor.

3.Locate your new setting:

<Setting Name="ReplaceSomething" Type="System.String" Scope="Application">
        <Value Profile="(Default)">            
        </Value>
    </Setting>

 

4.Edit the Type attribute in my case, i changed to:

<Setting Name="ReplaceSomething" Type="RegExHttpModule.RegExReplaceRule" Scope="Application">
        <Value Profile="(Default)">            
        </Value>
    </Setting>

5.And now place the Xml Serialization version of the object:

<Setting Name="ReplaceSomething" Type="RegExHttpModule.RegExReplaceRule" Scope="Application">
        <Value Profile="(Default)">           
            &lt;RegExReplaceRule xmlns:xsi=&quot;http://www.w3.org/2001/XMLSchema-instance&quot; xmlns:xsd=&quot;http://www.w3.org/2001/XMLSchema&quot;&gt;
            &lt;UrlRegularEx&gt;1&lt;/UrlRegularEx&gt;
            &lt;FileContentRegularEx&gt;2&lt;/FileContentRegularEx&gt;
            &lt;FileContentReplace&gt;3&lt;/FileContentReplace&gt;
            &lt;/RegExReplaceRule&gt;
        </Value>
    </Setting>

6.Now you can close de Xml Editor and click over the Settings file.

Disable multiple postback

How to disable multiple postbacks from a asp.net page (  the easy way, not the best):

1. Use asp.net Button control, check for OnClick and OnClientClick Property

2.OnClientClick you should add a call to the function DisableButtonOnPostBack:

<asp:Button ID="Button1" runat="server" OnClientClick="return Navigate();" onclick="Button1_Click" Text="Button" />

3.And then add the javascript.

<script type="text/javascript">

function DisableButtonOnPostBack()  {

if (!this.disabled) {
              this.disabled = true;
              return true;
          }
          else {
              return false;
          }

}

</script>

Dll not found. Reflection.

Hi,

If you have a error something like this one:

Try this:
From the Vs.net command ptompt, run the tool Fuslogvw.exe.
On settings select the "log bind failures to disk" option, and choose a local path for the log, and click ok.
Run you app, and after the error, select the refresh button, the dll missing should appear. If you select it, with double click you sould have some info to help you.
WARNING: After you are done, disable the log.
Thanks Mister Daniel for this info.
Cheers.

Configure the S.O. proxy settings to all users

Use proxycfg to display the current proxy setting.

Use the option “proxycfg –d”, to disable the proxy setting.

Use the option “proxycfg -u” to copy the proxy settings from the Internet Explorer user current settings

Teste do Windows Live Writer

Parece que agora a coisa está a começar a mexer.

Na mesma aplicação (leve), temos RSS Reader, Mail, Contactos Newsgroups, Autor de Blog,  Messenger.

Aquilo que gosto (desta fase de teste) é o facto de ser uma aplicação sem leve. Pena é que a funcionalidade de descarregar mails de outras contas seja para pagantes.
