Dear horece1,
i think the microcontroller baud rate is ok, i set it on 115200,
and i can use it for sms gateway sir, but for scan modem respond, it can not
Dear FvM
so how i know that the modem is in initially setup to the peer's baud rate or not, sir?
thanks

Dear horece1,
i had tried with your code, the result is same with output for my code
when i give AT+CSQ to modem wavecom, it replys owed
it should be reply the signal...
You'll think about suitable debugging means for your problem.
Hardware means:
- an oscilloscope to monitor the Rx and Tx data
- an UART spy adapter that taps Rx and Tx data and send it to a PC, at best two RS232 channels and Docklight software
Software means:
- AVR in system debugger
Regarding...
i use microcontroller ATmega 162, and i'm sure that the baud rate is correct, my sim900 is 115200 baud
your code is :
if(data[i]<'(space)'
break;
right ?
dear horece1
i had tried scan character from keyboard'input throught hyperterminal, my program is ok
but it doesn't ok when i tried it in wavecom modem
and please tell me about your code, i am a little confused sir
hai,
can you help me how to read responds from wavecom's modem ?
like as when i type "AT" in wavecom modem through hyperterminal, it will respond "ok"
but i use microcontroller in this case and display the respond in LCD
i had done make a program for this case, but it did not complete
the...

hi every one ,
i got problem with my sim 900,
when i try to using it for sms gateway in my sim 900, the respon was error, PS busy
when i check with AT+CSQ, the signal value was always 1 until 10
a few days ago, i can use it for sms gateway
why my sim 900 respon was error, PS busy?
help me...
Hi everyone,
i got problem with my sim 900,
my cable to antenna was broke, my cable was ufl to sma connector with female pin
i had tried in my country but i didn't find
then i tried to make it
and then when i try to using it for sms gateway in my sim 900, the respon was error, PS busy
when i...
hi sir, i had a antenna 900/1800 for sim900
but i didn't have this specification, about power transmit, loss cable, gain antenna etc
may be you can give me sir?
thanks
i had received "call ready" sir but when i try sending sms through hyperterminal
but, when i am sending sms through Microcontroller, how i know i get a "call ready" ?
every AT command i send, it didn't reply sir
hi sir,
before i setting hyperterminal with ATE1, sim900 can reply "something"
but in "Microcontroller", "Sim900 cann't reply anything", i using a interupt (ISR) on it, but my Microcontroller cann't detect reply from SIM900
i try using interupt (ISR) in hyperterminal, when i connect my...
may be you can teach me, how to scan character using array with getchar() sir, or anything else?
i will using it to know a reply from sim900 ?
thanks

my default baudrate from my sim900 is 115200 sir, i had done try with 9600 baudrate through HyperTerminal, but it can't work
i had done using your cide sir
printf("AT\r\n");
delay_ms(500);
printf("AT+CMGF=1\r\n");
delay_ms(500);
printf("AT+CMGS=\"083849852341\"\r\n");
delay_ms(2000);
printf("yes bisa");
delay_ms(2000);
putchar(26);
but still cann't sending sms
i had done connect my micro to PC, the data...
