I have this shield(http://www.sparkfun.com/commerce/product_info.php?products_id=9607).I new to this...all I want to do is send a simple text message...any help?Also if possible, turn the module on when I text it the number "1" or anything.

[Reply #1 on:]

This sequence sends a text message;

Serial.println("at+cmgf=1");
Serial.println("at+cmgs=\"214244****\"");
Serial.print("This is my message");
Serial.write(26); // this is ctrl-z

[Reply #2 on:]

I get an error for this with NewSoftserial "Serial.write(26); // this is ctrl-z"
how do i send it instead

really noob here

I get an error for this

My crystal ball is covered with fingerprints, and I'm out of Windex.

What error are you getting?

[Reply #4 on:]

sorry dude
When i compile i get following error

C:\Program Files (x86)\arduino-0018\libraries\NewSoftSerial/NewSoftSerial.h:71: error: 'virtual void NewSoftSerial::write(uint8_t)' is private

error: within this context


and it indicates on this row
cell.write(26); // this is ctrl-z

Your code snippet indicates that you are using the hardware serial instance Serial, but the error message says you are using a NewSoftSerial instance.

If you have a NewSoftSerial instance named mySerial, you can send ctrl-z this way:

Code:

byte ctrlz = 26;
mySerial.print(ctrlz);

Thx worked great

found this just
cell.print(0x1A, BYTE);
also worked to send the ctrlz

Hi I've got a problem, Im using a Mega2560 and it s not working.
Does anyone knows how to solve this problem.
I'm testing the code below , but the problem is the pin, cause I've read somewhere that i can not use the pin D0 to d9 as  serial. And I don t know how to solve it.

You've got 4 hardware serial ports on the Mega. Why do you need a software serial port, too?

Are you using the version of NewSoftSerial that was recently modified for the Mega? The "official" version does not work on the Mega.

Thank you PaulS. Now its working. Now i can sand sms and make calls.

[Reply #10 on:]

But now I have another problem.
I'm trying to send email using this shield but i don t know how.
Thanks

[Reply #11 on:]

please pals one urgent request, is this module alone is enough ( anything else to be bought along with it? ) and can it be interfaced to arduino uno!

please reply guys.


thanks

[Reply #12 on:]

what code to use if we want to use this shield to send email?? thanks. :o

Mine simply repeats SIND 1 and SIND 10 about every 10 seconds with about 5 characters of jibberish in between.  Does anyone know what could cause this?  If I'm lucky I may get a SIND 3 after 10 minutes and once got a SIND 4 and SIND 7.  I'm using the development board connected directly to a computer and have change BR to 9600 and band to 7.

Help would be hugely appreciated.

Thanks
