Severe Bug: N73 AT command support broken

N73 (and several other nokia phones, too including E51) understands only parts of the command set.

Example dialogs:

AT+CPMS?                                                                        
+CPMS: ,,,,,,,,                                                                                                                                                 
OK                                                                               
AT+CPMS=?                                                                       
+CPMS: (),(),()                                                                                                                                                 
OK                                                                              

Many other commands (e.g. in contact management) don't work either. I found no documentation regarding this behaviour.

I feel that Nokia should release information about how this phone is to be used. I wouldn't recommend anyone to pay in excess of 200€ for a phone that doesn't do what it's supposed to.

use lower speed in USB COM port

Hi,

i had the same problem above, and all i had to do was, search for the USB COM port that the phone was using, and lower the speed (i used 9600). because i only need to send a few SMS messages, i left the speed that low. after changing the speed, SMS and other commands work OK.

regards,

Oscar.

Oscar,

Thanks for the advice I am using the E51, I have cranked back the bit rate to 9600 and I still have the same issue. It seems to be more of an issue of storage of where the SMSs are stored. Does Nokia have any suggestion of where we should be accessing via AT commands to get to the SMSs?

command set differs from phone to phone

e.g. on some phones some commands are missing and not all commands are listed here and on referenced links...

Image Updated

-I (Mahbub_s60) added couple of images and related text in the article. It makes easier now (those pictures were hidden :-) ) to send AT command from PC

Wheateus - Hyper-Terminal to ASCII

I'm using the commands to send a text message:

AT+CSCA=+61418706700 The SMS message centre number for Telstra AT+CMGF=1 Format the modem for text mode AT+CMGS=XXXXXXXXXXX Mobile number for where you want the message to go to "Insert your message here" (Control-Z) Hold control z together at the same time Then do not push any other number then the message will be sent


This is what I have done in HyperTerminal but I wish to convert it to ASCII so that I can program an IC to send this command, can anyone help me with this for my school project

Thanks,

Wheateus

>Parakrama , I suggest you raise this on the discussion boards.

If you actually want an answer then go ask on the discussion boards. That is where you will find the most people who might know the answer to your question. This is an article on AT commands - it is unlikely the small number of people who might be viewing it will know the answer to your question.

Md. Kayesh - Windows does show E7 handset as modem

I attached E7-00 in Windows 7 and Windows XP. I found it as modem in Windows 7 but as Windows 7 doesn't have hyper Terminal i could not follow this page any more there. The i tried in Windows XP and there i could not find it as a modem. What should i do now. I need to check AT command response.

Gmedici - @Md. Kayesh - Windows does show E7 handset as modem+AT support incomplete for E52???

I was able to talk to my E52 over Bluetooth, Win7 and I see it as COM4. I used putty which is a good Hyperterminal free replacement. My problem is that it seems that not all AT commands work-- I can dial (ATD) I can answer a call (ATA) but I can't hangup (ATH=ERROR) and, worse, I can't figure a way of getting the Caller Line Identification. Anybody can give an advice? Thanks,

Gmedici - Re: AT support incomplete for E52???

OK solved (I think!...)

It turns out that (i don't know why) after issuing this command:

AT+CLIP=1

the modem reports the CLI after RING

and that after issuing

AT+CVHU=0

the command ATH does what it is expected to, ie it hangs up the call

Kingsonprisonic - E-Recharge AT Commands

Dear sir,

Currently i am developing an application in vb.net. Which will able to send sms through a nokia mobile phone and Airtel Sim card.

Now I know the AT commands for sending and receiving SMS's .

How can i send e-recharge through LAPO SIM (MASTER SIM) using AT commands.

In LAPO SIM(also known as Demo SIM/Master SIM), an application called "Refill Amount" already installed.

1. The retailer open this app and put my number 2. Now he put the amount to send 3. Now he enter his PIN 4. Now he send the amount

And at last My account is successfully recharged...

I think this application also use the GSM modem to send commands. I just want to know the commands for sending recharge to other phones....

Someone from this community say that i should ask this info from my operator...

But as you can see that the application just recharge other mobile by just sending sms then i think there is a way to do same thing manually by AT commands....


If any other method available please let me know.


Thanks in advance....
