Hi, Maybe it's useful for those who will use the Siemens A60 or A65 phones. These phones are moving to 'Airkraft mode' after switch on. In this state, not all AT-commands are available via serial port. AT-commands that relate to the SIM card does not work until you confirm the 'switch on' of the pho...

Hi,
Please ignore my questions in previous message. I already resolved the problem.
the problem was that sms message is not saved in the sim card (i dont know why) by the phone menu.
For resolving, I used command AT+CMGW for save sms message in pdu format to sim card.

Happy New Year, friends! eDo, thanks for the advice and suggestions. I also hope that in Ukraine will be peace. I wish peace to All in new year. Phone M35i I still could not find. But I found another phone - A65. As it is written in the article, it should work without problems also as M35i. Ok, the ...

I really do not know your language, sorry guys. I am from Ukraine.
Actually, I know English is not so good also.
But some of your words I know, because they are similar to my native language.

trax, thank you for help !
I do not lose a hope to connect A60. I will let you know If I find a solution.

I received following commands on 19200 baud rate: ATZ ATE0 ATV0 AT+CPIN=0000 AT+CLIP=1 AT+CPBS=”SM” AT+CPMS=”SM”,”SM”,”SM” The problem that i see: my modem does not support the AT+CLIP, AT+CPBS, AT+CPMS commands. When i send their to modem by hand, i received the ERROR. I will look similar commands ...

i have connected the PC-terminal to PIC instead a phone and receive following 3-byte portions:
d0 36 fe
d0 3a fe
d0 3e fe
d0 76 fe
...
and so on, at regular time intervals.
In the terminal window (i use minicom under Linux) it looks like here (please see attached picture)

Yes, I just wanted to connect the computer's serial port instead of the phone to the PIC via rs232-ttl cable. But you have a better solution - connect it in parallel for sniffing. You already sent the source code to me a week ago. Thank you for this. I will check the communications between phone and...

Check the connection. I never used A60... I hope it has AT modem inside :-) The problem was that I forgot to set the jumper on the common wire (Vss). :shock: I fixed it, and now i have the next issue :) Now, when I turn on the power, the LED blink once and several seconds off. After that, LED light...

What GSM phone did you connect? Also, make sure you connected TX->RX and RX->TX and GND->GND between phone<->alarm. I have connected Siemens A60. Also i tried to run without phone. Result the same. I thought that the device was supposed to blink once if the phone is absent. If the reason in the pho...

Hi
I did a dip version of 'Tiny gsm alarm' and use pic16f628a. I load the firmware file hex-firmware/firmware_22-11-2011/callalarmsys_PIC16F628A.HEX.
When I turn on the power to the circuit, LED lights up and does not go out.
What could be the problem? Tell me what to check.
Thanks.
