[camolas]

Hi there.

For starters i will put the my way off connecting the nokia 6210 with the pic no max 232 need, later i will post the full code.

Hey dude, what is it used for exactly?

[camolas]

Hi,

This is for conecting a nokia phone and a pic, you will control the phone from the pic, later i will post a code where you can with a serial gps send a sms with the gps data.

Xau.

Try sending "numero" like you are for "lat" and "Lon", one piece at a time.

[aratti]

Camola, try the following:

Use a larger array in such a way that you can accomodate the calling string in the initial part of the array:

Arry[0]=65
Arry[1]=84
Arry[2]=43
Arry[3]=67
Arry[4]=77
Arry[5]=71
Arry[6]=83
ArrY[7]=43

The above sequence contains the string AT+CMGS=+

Than you tranfer the sender number (12 bytes) in Arry[8] to Arry[19]. Remember that last byte should always be Arry[20]=13
At this point you can make the call:


For A0=0 to 20
serout Mtx,T9600,[Arry[A0]]
Next A0

Immediatly after the call you have to wait the modem acknowledge ">". Here an example of code:

Flag=0
WSend:
Flag=Flag+1
if Flag>20 then NoSMS
Serin MRx,T9600,500,WSend,[ ">"] , A0
If A0=32 then SendTxt
serout Mtx,T9600,[27]
pause 5000
goto NoSMS

The code above will jump to label "SendTxt" if the modem answer corectly, otherwise it will abort the call with ascii 27 and jump to label "NoSMS"

At label "SendTxt" you will wite your code to send your string.

Naturally you should change Serin/Serout to fit your code

Hi,

Can you please explain this part i do not now how i will put the numbers that i get from the array "numero" to the "Arry" one in ascii.

Thanks,

Hi,

I will try it then i will post the results.

Thanks,

[mister_e]

Look the ASCII table

A=65
T=84
and so on

the above could also be written like...



Arry[0]="A"
Arry[1]="T"
// etc etc etc

[mackrackit]

Not sure if this will help you now or not, but it might.

[aratti]

Camolas, The array "numero" contain the string so:

For A0=8 to 19
arry[A0]=numero[A0-8]
next A0
Arry[20]=13

But you can put the value directly in arry[8] to arry[19] instead to put it in the array "numero"

Your code must hang if there is no enough deposit on the sim card, alternativelay u can see gsm network connectivity available for make more reliable the sms dispachting, i don't know how that cell phone works but if it has log for sms in areas without gsm coverage and the pic still in the Lo loop, once you are back on GSM coverage, simply alll your deposit can be wasted in several hundred SAME message !!

but . . . is just my point of view... :rolleyes:

Hi,

Thanks for the inputs, for the deposit there is no problem because in my code i delet the "REC UNREAD" sms

"APAGA:
HSerout ["AT+CMGD=1",13,10]' apaga sms 1
hserin 10000,APAGA,[WAIT("OK")]
HSerout ["AT+CMGD=2",13,10]
Pause 5000"

The gsm coverage is very good point that you have made it need to be changed in a futer update.


I have been in a wardware problem now this works very good in a QL200-A4 board but in my home made pcb not (some times works some not..) the pic cant get the phone Tx (i see it in hyperterminal that phone gets the pic Tx e reply but pic cant get it) i have put a 10K pulldown and up in phones Tx but no sucess.Need hellp on that if you mates can hellp me thanks.

Hi Al,

Hare you saying thar i sould conect the max pin 13 to Rx phone and max pin 14 to Tx phone or to nokia data cable 3,2 pins and gnd?
Thanks,

Xau.

[aratti]

Camola, modem connection should not be crossed (I don't know with nokia) but try, if it doesn't work invert Rx with Tx at the phone cable.

Before to connect the max232 to the phone, make sure that is a standard RS232. If the phone has a 3.3 volts system you will blowup the phone communication line. In this case you should use a different approch.

Remember that if you connect the max232 to the PC serial port then Rx and Tx should be crossed. The connection given in the schematic are for a PC serial connection.

Then try SERIN2 in inverted mode for a test. Could be an external hardware problem?

[aratti]

Camola, from your code it seems that you are using portC.6 and PortC.7 for communication with cellphone. If this is correct then:

Connect pic portC.6 to max232 pin 11 (TTL Tx)
Connect pic portC.7 to max232 pin 12 (TTL Rx)
Connect max232 pin 14 to phone serial cable pin 3 (Should be Rx ?)
Connect max232 pin 13 to phone serial cable pin 2 (should be Tx ?)
Connect circuit ground to phone serial cable pin 5

(If you connect it to the PC I assume you have a 9 pins DB female connector)

It should work. If it doesn't invert connections at the serial cable pins 2 & 3

Hi,

But is not need to give the nokia data cable any power?

Thanks

[aratti]

Yes it have and there are nokia cables to conect it to pc rs232 i have one from nokia and works fine with hyperterminal.

Did you powered the cable working with hyperterminal? If not you don't need to do it with max232.

When i use it with the pc hyperterminal there is no need for external power the com port it gives the power that i need it.

Can i use in same code more the one Serout2/in2 on diferent ports to control phone and gps and others serial devices?

Thanks

[aratti]

Can i use in same code more the one Serout2/in2 on diferent ports to control phone and gps and others serial devices?

Yes you can. But when you service one device you don't see the others (If device A will send data while you are servicing device B, device A data will be lost"

Al.

[mackrackit]

Can i use in same code more the one Serout2/in2 on diferent ports to control phone and gps and others serial devices?

I have not done phones, but the others many times.

As long as the pin is set for digital SERIN/OUT/2 will work on any pin that is an I/O, You can have as many pins as you want taking turns doing serial.
You can mix and match SERIN, SERIN2, and HSERIN.
If you are slick, you can HSERIN on the hardware and SEROUT on another.

[camolas]

Hi Camolas,
about the signal coverage, what you think about to use:
AT+CSQ

it should tell you how good is the signal.
In the modem I have it say that
0 - 9 = very poor or not enough
10 - 15 = good
16 - 31 = very good

May this help you.
If you get your code even good for signal coverage, do you like to share it?

[linoko]

HI camolas,
I'm very like your project but i have some question.
Please send me if it is possible the schematic of device and post please the actual source code.
I try earlier version of the source code and i can't see device working.
I connect Siemens S35 the device send AT but cellphone did not answer with OK. Please help me with this project.

Best regards Konstantin
Sofia, Bulgaria

[aratti]

Mikebar, there is no need to waste pic memory space for checking the signal coverage.
The main reason is that the system will use "SMS" for answering and if signal is too poor than modem will not send the message till signal will return to an acceptable level.

---------------------------------------------------------------------------------------------------------------------------------

Linoko, very likely your siemens 35 use only "PDU mode" and you need "TEXT mode".

To check if your phone works in text mode, connect it to hyperteminal and Tx the following command:

AT+CMGF=1

press enter and check the answer.

If answer is "OK" then your phone works also in TEXT mode.

Thank you for the info.
But ALL the phones have the same behaviour you described or just some model? it is defined some standard for that behaviour or any producer think is "best solution"?

Thanks in advance.

[aratti]

Yes all phones behave in this way. Try to send a sms to your phone (switched off). You will receive it when your phone will be switched on again.

YEP, that's the reason why SMS messages are delayed for minutes hours (carrier dependant) BUT
U must have in mind that SIM card (were SMS are stored by default) has 20 memory location for only SMS if you try to send more, the answer becomes an "ERROR" instead and you wont know what exactly happen, if you really want to know what happen you should check GSM coverage !

please don't forget saving your phone settings using:
AT+CMGF=1 <CR><LF>

Al.

Yes, this is true.
But my guess was another.
Suppose the following scenario:
-I've a mobile phone connected to the PIC
- I wish to send an SMS from that phone
- now suppose that there is not enough rf power to send it.
It is not better to check first if the RF is enough before attempt to send the SMS?

You are talking about to send an SMS to a switched-off mobile. Of course it work because the SMS is sended to your carrier from yuor phone that have enough rf strenght in the moment it is sending the message. Then is your carrier that take care to deliver to the recipient phone as soon it is reachable.
As you can see, I'm talking about a different setup.

Hi Friends,
The project of Camolas is very interesting and i try to create my own device. This device /schematic is posted below/ is based on the source code of Camolas with little changes on the source code.
My GSM cellphone is Sony_ericsson T630. The phone supports AT+CMGF=1.

The USART settings are:
DEFINE OSC 20
DEFINE HSER_RCSTA 90h ' Enable serial port & continuous receive
DEFINE HSER_TXSTA 24h ' Enable transmit, BRGH = 1
DEFINE HSER_SPBRG 64 ' 19200 Baud @ 20MHz, 0.16%
DEFINE HSER_CLROERR 1 ' Clear overflow automatically

But i have a problem.
The problem is in Hserin command, i thing that the PIC don't recieve or understand the answer (ok) from cellphone.

for example:
TEST:

This is from Camolas' code


HSERIN 10000,UM,[WAIT("OK")]

Your code


HSERIN 10000,TEST,WAIT("OK"), the code hangs here

See the difference in the syntax.

The project of Camolas is very interesting and i try to create my own device. This device /schematic is posted below/ is based on the source code of Camolas with little changes on the source code.
I don't see where the original poster actually posted working code...so, I can only infer that any code you may have cut/pasted is also flawed.
