How is the shield powered (external 9V)?
It is powered from USB only. Havent had any problems so far
Nope but it should be possibleHave you tried to command the shield from a PC with something like Hyper Terminal as well (do you know if it is possible)?
I looked around a bit, but couldnt find any that had been tested with Netduino. This was the cheapest alternative.Did you look at other GPRS shields as well (why did you decide on this shield)?

UPDATE : The attachment is outdatet. Go to the project codeplexpage here instead:

The driver has lots of new functionality like HTTP POST and other improvements.
Hi dcypher,
I use your library but I've an issue...
When I open seedStudioGSM.cs, VS2010 don't find "RegularExpressions;" in "using System.Text.RegularExpressions;"
Why?
Thanks!

Hello everyone. Can someone suggest me where to buy this other than seedstudio since they have none in stock?
Is it possible to integrate an ultrasonic sensor (say this: http://www.sparkfun.com/products/8501) with the netduino and send sms when the sensors reads a specified threshold??
Could someone help me out? I need to be sure this can be done before buying stuff!

I tried to get the GPRS shield (v1.2) working, and for calling someone I was successfull, but sending a text message does not work.
- With the request/response (see below) it ends up with "+CS EROR: PSbusy"
- Additionally what I think is confusing as you can see with the number of the sms/text central in the response the '7' is missing. Same happens with the receiver number...always the 6th number is missing in the response - Why?
- As you also can see in the message, following characters in the response are missing: B, E, I, O, W, 7 - Why?
The source code I used is this one, with the respective commands called.
//Switch to sms mode Input: AT+CMGF=1 Response: AT+CMGF=1 Response: OK //Set message for sms central of provider Input: AT+CSCA="+491710760000" Response: A+CCA=+49170760000" //Set phone number of receiver Input: AT+CMGS=" +49160123456789" Response: OKA+CGS=+4916123456789" //Set text from the sms Input: ABCDEFGHIJKLMNOPQRSTUVWXYZ0123456789 Response: >ACDFGHJKLMNPQRSTUVXYZ012345689 ----No for about 5 seconds nothing happens--- Response: > Response: +CS EROR: PSbusy

ok, the lost characters problem is now fixed...was a bug in my program ;-(
But still when trying to send text messages I get the response "+CMS ERROR: PS busy"
Anyone had the same problem?
Thanks

Hi Kentuch,
> I use the Arduino 1.0 software
You know you're on the Netduino forums, right? That's a completely different piece of hardware. If you need the arduino forums, you can find them here:http://arduino.cc/forum/

Hi.
I've been working with Seeduino GSM shield also, and have been getting +CMS ERROR: PS busy error as well. I have a TMobile sim card and just refilled it, but it had run out. TMobile says it is active. Can anyone shed some light on the meaning of PS busy? I'd love to get this shield working.
code is from seedStudioGSM class:
public void SendSMS(string msisdn, string message)
{
PrintLine("");
PrintLine("AT+CSCS="GSM"");
Thread.Sleep(1000);
PrintLine("AT+CMGF=1");
Thread.Sleep(500);
PrintLine("AT+CMGS="" + msisdn + "",145");
PrintLine(message,
true, 10000);
Thread.Sleep(500);
PrintEnd();
}

This code worked for me with the GPRS Shield V2.0:
public void SendSMS(string msisdn, string message)
{
PrintLine("AT+CMGF=1r", true);
Thread.Sleep(100);
PrintLine("AT+CMGS="" + msisdn + ""r", false);
Thread.Sleep(100);
PrintLine(message + (char)(26));
Thread.Sleep(100);
PrintLine("");
Thread.Sleep(500);
}
You also have to remove the r in the PrintLine function with this version:
//Print(line + "r");
Print(line);
