2476  Using Arduino / Networking, Protocols, and Devices / Re: W5100/Ethernet cannot use socket as UDP after using it as TCP on: April 28, 2013, 12:12:04 pm
Maybe you are right. Maybe the delay waiting for the response from the dns server is not long enough. That could cause the dns fail.

edit: Your test is still running on my Arduino. It has not missed a beat since I started it.
Just so you know...

I'm not firing at you.  smiley  I'm just stating a fact. I am not fond of UDP either as a reliable transfer, but we are subjected to it through theses services.

@sonnyyu: That is a good thought, but NTP, DNS, and DHCP use UDP. You really can't avoid it.

I am concerned about DoS when publishing my public ip, and not because of this code. Here is my serial monitor display for a short run. It will go on for hours like this.

Give me a bit to setup the test again. I am testing the ethernet shield's dhcp client function. I think my router has a bug in the dhcp server service. I will replace my public ip with a phoney. I don't need any DoS attacks. I get enough, thanks.

Check back in a bit... smiley

My updateDB2.php are working when execute from my Browser (http://localhost/updatedb2.php)
That is a browser on the server. That is not a good test. Try that from another computer on the localnet.

I was involved in another thread like this, but I can't find it right now. There was a setting in the php extensions that allowed only localhost access only. If I find it, I'll post again.
2482  Using Arduino / Storage / Re: spi trouble when adding second device on: April 28, 2013, 09:43:58 am
Now disable the SD and try accessing the KTA.
Code:
void setup() {
  Serial.begin(9600);

  // disable the SD
  pinMode(10, OUTPUT);
  digitalWrite(10, HIGH);

  // now try accessing your KTA here
}
I think you are catching on to this.  smiley
2483  Using Arduino / Storage / Re: spi trouble when adding second device on: April 28, 2013, 06:16:01 am
Try the SD first. Disable the KTA259 SPI first, then see if the SD works ok alone.
Code:
void setup() {
  Serial.begin(9600);

  // disable the KTA259 SPI
  pinMode(9, OUTPUT);
  digitalWrite(9, HIGH);

  Serial.print(F("Starting SD..."));
  if(!SD.begin(10)) Serial.println(F("failed"));
  else Serial.println(F("ok"));
Does the SD start ok?
2484  Using Arduino / Networking, Protocols, and Devices / Re: Inserting graph javascript into sample web server code? on: April 28, 2013, 06:08:14 am
And it works ok when you tested it in a web server like IIS or Apache? Get the script working first, then import it to the Arduino.
2485  Using Arduino / Networking, Protocols, and Devices / Re: Inserting graph javascript into sample web server code? on: April 27, 2013, 11:12:17 pm
There is already an example of JavaScript in that server code. Here it is:
Code:
         client.println(F("<head><script type=\"text/javascript\">"));
          client.println(F("function show_alert() {alert(\"This is an alert\");}"));
          client.println(F("</script></head>"));

You can split the lines like this if you wish.
Code:
         client.println(F("<head><script type=\"text/javascript\">"));
          client.println(F("function show_alert() {"));
          client.println(F("  alert(\"This is an alert\");"));
          client.println(F("}"));
          client.println(F("</script></head>"));

It will look like this if you view the page source:
Quote
<head><script type="text/javascript">
function show_alert() {
  alert("This is an alert");
}
</script></head>

edit: Missed some double quotes. Got 'em.
2486  Using Arduino / Project Guidance / Re: Arduino Uno+Ethernet Shield+DHT 11 project on: April 27, 2013, 10:36:28 am
That would be a delay out of your control. It is the time it takes to establish the connection, verify your account stuff, insert/retrieve the data into the database, then send a response.

I have used the following code and it works, i can see the grapichs and the temp and humidity level on the cosm portal but ive got a big delay between measurements..  
Big delay? Like 15 to 20 seconds? Or a couple hours?

edit: Is that big delay between measurements?
Or from the time the measurement is sent to the time it is displayed on the webpage?

2489  Using Arduino / Project Guidance / Re: Arduino Uno+Ethernet Shield+DHT 11 project on: April 27, 2013, 07:03:47 am
I use my own stuff. I have 3 servers online all the time, and all have php/mysql extensions enabled on the web servers. However, that would be harder to demonstrate from a remote location.
2490  Using Arduino / Project Guidance / Re: Arduino Uno+Ethernet Shield+DHT 11 project on: April 27, 2013, 06:52:10 am
Ok, so after I share the connection the feed from arduino to cosm should work?
I won't guarantee that, but you should be able to connect to the internet with the Arduino/shield. I don't use Cosm.
