Gsm/Gps Tracker

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...

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.

Xau.

Camola, remove the resistors from the serial line and use a Max232.

Camola, I don't see the pinout in your diagram so I don't know if you have wired it correctly. See the attached schematic for a correct wiring.

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?

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.
