hello to all,
I'm trying to order a printer via SMS such a way that the printer prints the SMS received by the GSM. Indeed, I used GL865 Telit GSM module, a PIC16F877, a thermal printer. the communication between GL865 is via serial port. If the GSM received a message, the microcontroller will transfer the message to the printer via serial port. My problem is the program of the PIC.
I am looking for a full program or for example used in this application.
Help me please.
Thank you in advance

| I just want a code of the connection between PIC and GSM module. Receiving and sending messages between the two. |

Please I need code for PIC. Just the first part ie how to communicate between GSM and PIC such a way that I receive only SMS and save them.
I use PICC compiler |

I don't have that GSM module and when I go to download the hardware PDF, IE8 doesn't unblock it but goes to new Google.....arrgh ,so I can't get the PDF!
In general though you'll need some 'MAX232' chips and some simple serial software.There are several examples on this forum,just use the 'search' option on the top of the screen.
Be sure that all hardware is compatible, especially voltage levels! You MUST have level translators if GSM is 3.3v and the PIC is 5v. |

I made a kind of sms's control remote with a gsm module and 16F886 pic. Before to start the pic program I've used hyperterminal in order to understand how works the incomming sms. In my case only I've used phone number and the text message in my program.
Here a little part if you send the sms On you turn on Led_out and if you send Off you turn off Led Out (pin_B4).

Thank you very much for your help.
May you explain how this code and the connecting pins of Port.
I want to understand your code because it validated by the compiler for that I'll change it to suit my application. My application is to make communication between the PIC and the mobile phone as follows:
- The PIC enters a wait loop by sending the command "AT + CMGS" to the GSM receives an SMS in the PIC responds to a Command "+ CMGS"
-The PIC sends a command to receive the message and displays it on an LCD screen.
-Each SMS received by the PIC, it sends a confirmation message to the GSM.
May you help me please. |

In this driver, I found the problem:
1 - Normally this program must receive a sms, on, or off to on or off an LED.
2 - What is the exact role of input input (IN_ONOFF), this button is used for what reason? ,
3-printf("Inputs - Outputs\n\r"); ????why?
4-printf("1 / 1\n"); ????
5-printf("%c / %c\n",in_state,out_state);// ??????????
6-ptr=strstr(buffer,r2_on) What is it? « ptr » , "strstr" ?
7-strncmp(ptr,r2_on,2)? what is it strncmp.
8-what is its role of fonction void demora() ,and , void verifica_ok (void)
9-I found that in all the GSM program, it is used this table (buffer[BUFFER_SIZE]) , this table buffer it is used for what reason
I found no clear explanation on the topics of GSM, I ask all programmers helped me on this subject, especially who applied this driver, I want to understand the operating principle, normally when the Module gsm receive sms, in this case it affects 1 in B4, but why the programmer used the routine send sms, in logic, I use another mobile for the word is sent to my mobile phone unit, so in this case we use in our program that the driver for read sms, what is right? ...... |

Hi kamillas,
You are asking such basic 'C' questions, that it's hard not to conclude that this project is well beyond your (demonstrated) abilities with PIC processors and the CCS 'C' compiler. Seriously, at least half of your questions are readily answerable using Google or the forum search. If you consistently show an unwillingness to do any work, no one is going to bother to help you! There is at least one complete program in the forum archives that shows you how to switch LEDs On/Off under SMS control, authored by user 'Gabriel'. Did you find it?
Fundamentally, this is not a difficult task, but you've got to have a good handle on serial communications first, then string parsing, and then string manipulation. So far, you seem to be seriously lacking in the skills for all three tasks.
I don't offer these observations in a mean-spirited way, but rather as a friendly suggestion that you fundamentally change the way you go about your problem solving.
Good Luck!
John |

@hadipic: This post makes no sense. Why did you post it?
- You are posting in a thread that was silent for 3 years.
- There is no question or remark for why you posted the code.
- The code is incomplete.
- The code is difficult to read because you didn't use the 'code' buttons. |
