sms pic

Hi chenoi

First, you must search by "pdu" or "sms" in this forum.

To start, nokia have a propietary protocolos, known by MBUS/FBUS. To comunicate your PIC to cell phone you have to use this protocol.

But, you can use another way. Using AT command, this ist work for each cell phone that support AT command.

This AT command are characters in 8 bits, which you can send from PIC to cell phone in serial mode. The phone receive this string sequence and run the instrucction to send the SMS to desired destination.

Cell phone send SMS in PDU and Text mode. no all cell phone suport text mode.

to test the operation sms mode:

at+cmgf? enter

0 => pdu mode
1 => text mode

To create a sms in pdu mode, you can use the "pduspy" software, which creates the pdu frame with "data information". This pdu is a string of ASCII character, and take it, insert it in the PIC , and send it to the phone, after send AT command

example: send mesagge in text mode using

AT+CMGf= 1 ==> set phone to text mode sms
AT+cmgs="+4594567890" , enter key ==> cell phone number destination of message
>Text to send + ctrl+z => to finish the text to send.

the phone answers with following:

+cmgs: 0 => 0 is the message reference , how much sms has been send by cell phone, it should be other numbers


Now, you must investigate the text or pdu mode of sms, and how create the code for PIC



sorry to all for my bad english


bye

pic sms control

OK

you have to search in google for:

"nokia pin out" or "nokia cable schematic"

This for see the circuit to make, the input voltage for nokia phones is 2,7 volt. The pic send 5 volt for a logic 1. You can use a resistor in serie with a zener diode, and conect de input pin of nokia to cathode of zener diode to obtanin 2,7 volts. Idem for RX system.

view the attached circuit.

The 16F84´s software must have a rs232 protocol implemented in software.

nokia fbus pic

You can find some code samples at www.usbdeveloper.com.

They are using a Microchip to send SMS via an external mobile phone.
So, I think you can work further from there.

nokia 3310 sms controller

Hi,

Im sorry to say but there is no why easy or a hex file to solve your problems. you will need to write some code on the PIC. you best way is this:
Buy a Data cable for you mobile phone, its much more easy then to build one. Be sure that the data cable can work with AT command, FBUS and MBUS are very hard to use and debug protocoles.
Then on the PIC write the code to receive and trasmit with your UART.
When the pic will load it sould program the phone to use TEXT mode and not PDU.
Then use the attached files that i send to read and delte the received SMS.
The easy way to turn things on and off is buy sending simple Text sms to the phone. for example, send 31 to turn output 3 on, and 30 to turn output 3 off.

The attached files will help you to understand the AT command structure, And the Original Nokia file will show you how to read the SMS.
Good luck.

FBUS and MBUS cannot and will not understand AT Commands using an FBUS/MBUS cable alone.

FROM https://www.zfone.com/mobiles.php/phoneid/10245

I found that you G530 does not have a MODEM built in, perhaps it does not have a AT command set implemented.....sorry, you must buy a new cell phone
