Hello

I am trying also to read data from raymarine instuments with seatalk. Can you post me the code that you say it is working?
2  Using Arduino / Installation & Troubleshooting / Error while burning bootloader on: January 02, 2012, 07:16:46 am
I was palying with the xbee. And the xbee shield jumpers was in the wrong place. After a some times uploading sketchs i got this error.
Done uploading
avrdude: stk500_getsync(): not in sync: resp=0x00

After googling i found out that my avr microcontroler needs to be re-burned.

So i choosed this way ->Minimal Circuit (Eliminating the External Clock)
from here
http://arduino.cc/en/Tutorial/ArduinoToBreadboard

and i got this error
avrdude: stk500_getsync(): not in sync: resp=0x00
avrdude: stk500_disable(): protocol error, expect=0x14, resp=0x51

Do i have any hopes to fix it?

thanks.

thank you for your interst. This days i didn't had so much time for it. I'll try it the next days, i will come up again with the results.

thank you again!

I have tried both solutions of the switch. smiley-sad

Not for sure. I haven't found anywhere. But what else can it be rather that what it does in the other gsm shields? I think is for when is connected...

I don't have experience with this shield but I do have a lot of experience with the SIM900 itself.  I tried searching around to find some decent schematics for this shield but could really find much. 

Are there any LED's on the board for power or network status?

Do you see any indication whatsoever that the unit is even turning on?

Yes there is one led. But it never light on.

I have done this diagram to find out what is happening in the shield, and if i can bypass it.

Also this pdf is better http://www.svtehs.com/simcom/docs/SIM900_HD_V101.pdf


No support still recieved from the future support email.. They haven't answered me...

Thanks for your interest..
As far as i understand what you are saying you need this schema that i have attached. The chip is a sim900 of simcom here is the referance->http://wm.sim.com/Sim/News/photo/2010222155735.pdf .

this is the product .

the between arduino and the shield with the sim900 is the shield that i have solder. You propose that i skip this one and connect my arduino directly to this pcb with the sim900?


thanks

First the soldering. I did it with someone who knew how to do it. And i can also show you a picture of it that it is ok. I double check it now that you told me show.
Second the code thing. I have tried so many times unpluging it and after plug it but still didn't work. Every time i changed something in the code. I had to unpluged the shield, so it can be uploaded. Otherwise it was stuck, an it could uploaded.

I also send them an email this moring and still i haven't got any answer....

thank for your interest, any other ideas?

11  Using Arduino / Networking, Protocols, and Devices / Gsm Shield doesn't response on: November 17, 2011, 05:15:55 am
Hello ,
i bought this Gsm Shield from "Futura Elettronica" and since then i have comed up only with problems. First in the website the mark the products that needs soldering, and that one wasn't marked. When i opened it the shield needed soldering. So first i had to learn how to do it. So when i finished this task i buyed a sim card from a network here in Greece and i put the gsm shield on my Arduino. I tryed the "GSM_Shield_Reg.pde" to see if i can register the module and i get "Gsm doesn't response". The only example that work is this that check the version.

Any help would be most welcome...

Here is the product.

12  Using Arduino / General Electronics / how read from 50 or maybe more inputs(50 pins) on: October 14, 2011, 05:51:24 am
I want to read from my arduino from 50 or maybe more pins. I have understand that i can do this with a Shift Register(ICs). I what's the bigest shift register i can find, and if this is the best practice to do it.


Thanks.
13  Using Arduino / Networking, Protocols, and Devices / Connect to uno with wifi shield through my smartphone on: July 22, 2011, 06:59:02 am
I bought CuHead WiFi Shield for Arduino http://www.linksprite.com/product/showproduct.php?id=73&lang=en. And i want to connect to it through my android phone(through http). So my arduino must act like a rooter. The android get ip and after show the page. Is this possible to be done? Any links will be very usefull.

thanks
ps 1. i tried the webserver example from the wishield and as far i understand, this is to connect to an existing router.(simple server, wasn't working)
ps 2. I am realy new in arduino so please give analytical answers.

thanks.

I just want to try make it myself...
15  Using Arduino / General Electronics / 4 relay homemade pcb on: May 23, 2011, 12:25:46 pm
hellow,
i want to create a 4 realy pcd with 3 pins screw terminals. i want to have a separate power supply from arduino, and maybe i will also put some leds on it. Even thow i have done this in my breadboard, i dont know how to start to make a pcb with this and how is the best way to put them in a pcb. Are any already done desings for this thing?


thanks in advance
