1  Using Arduino / Programming Questions / Re: Arduino GPS Shield by iteadstudio.com on: March 16, 2014, 11:44:00 am
I'm new with Arduino. How do you check or set the RX and TX jumpers? I have an Arduino Mega. I can see a row of jumpers RX - TX (0 0,3 3,2 2,1 1) but the shield gets only to the TX0(1) and RX0(1) and I read here that you must set it to 3,4. How does it works?

I'm using the replay  #130 and a I get this message: "No GPS data received: check wiring". At some time I changed the voltage from 5 to 3.3. Now I have it at 5. Did I kill my GPS?  smiley-cry

Thanks for your help
2  Using Arduino / Installation & Troubleshooting / Error connecting an ITead Arduino GPS shield to an Arduino Mega on: March 15, 2014, 11:56:01 am
Hello

I have an Arduino Mega 2560 and the ITead GPS Shield http://imall.iteadstudio.com/im120417017.html (Am I breaking some rules here?) and when I load the blink sketch

avrdude: stk500v2_ReceiveMessage(): timeout
avrdude: stk500v2_ReceiveMessage(): timeout
avrdude: stk500v2_ReceiveMessage(): timeout
avrdude: stk500v2_ReceiveMessage(): timeout
avrdude: stk500v2_ReceiveMessage(): timeout
avrdude: stk500v2_ReceiveMessage(): timeout
avrdude: stk500v2_getsync(): timeout communicating with programmer


I tried the same Mega board with a Arduino WiFi shield and seems to work perfectly as the Mega itself.
What could be wrong?
Thanks!
3  International / Hardware / Ayuda en la seleccion de modulos para un proyecto de GPS+GSM on: April 03, 2013, 11:30:43 pm
Hola, soy nuevo con Arduino y estoy en un proyecto de rastreo de vehiculos con arduino. He seleccionado los siguientes articulos que creo que son los que necesitare.

-Arduino Uno
-Cellular shield con modulo SM5100B http://www.robodacta.mx/index.php?dispatch=products.view&product_id=29865
-Antena celular quad-band, SMAhttp://www.robodacta.mx/index.php?dispatch=products.view&product_id=30105
-GPS shield con el modulo  SiRF star III http://cosasdeingenieria.com/esp/index/item/459/43/shield-gps-compatible-con-arduino
-Antena GPS con conector SMA 3Vhttp://cosasdeingenieria.com/esp/index/item/238/antena-para-gps-montaje-magnetico-con-conector-sma-de-3v
-8-pin & 6-pin headers (x2)

Me faltara adquirir algo? habra algun problema de compatibilidad?. Sobre la antena celular, me hace falta un cable extra para conectarlo al shield celular?

Gracias por su ayuda

thank you, thats a lot I have to learn and this will help
5  Using Arduino / Project Guidance / [Arduino + GPS + GSM] Am I getting the appropiate modules? on: April 02, 2013, 11:45:43 pm
Helo, I'm new in the Arduino world and I have little knowledge. I haven't tried with anything yet and I need to do a project using arduino (about vehicle tracking in real time) so I have been looking for modules that I could need so I did this list:

-Arduino Uno
-Cellular shield with SM5100B module http://www.robodacta.mx/index.php?dispatch=products.view&product_id=29865
-Cellular antenna  quad-band, SMAhttp://www.robodacta.mx/index.php?dispatch=products.view&product_id=30105
-GPS shield with the  SiRF star III module http://cosasdeingenieria.com/esp/index/item/459/43/shield-gps-compatible-con-arduino
-GPS antenna with a SMA connector 3Vhttp://cosasdeingenieria.com/esp/index/item/238/antena-para-gps-montaje-magnetico-con-conector-sma-de-3v
-8-pin & 6-pin headers (x2)

This is what I think I have to buy, I'm looking for something cheap, what do you think? I have these questions:
Is there some compatibility issues I should know?
What if I found some projects and code that uses the same (gps+gsm) but it uses other kind of modules (different model or manufacturer), Will it be usefull or do I have to look for tutorials or examples that uses the same I have?

Thanks any help will be appreciated
6  Using Arduino / Networking, Protocols, and Devices / Send data to web service from a arduino+GPS+GSM on: March 02, 2013, 01:14:19 pm
Hello.

I'm developing a vehicle tracking system and one of the ways I can do this is with a arduino that gets the coordinates of the vehicle and sends it to a server through 3G with the GSM module.

I already have the server working with a SOAP web service, this was intended to work with a smartphone as gps tracker but now we want to try it with the arduino.
My question is: Based on your experience, which are the best ways to send coordinates to the server using GSM and web services? or I have to change something in the server?

I haven't decided which modules to get so you can suggest which are the appropiate

Thanks
