Help: Some problems with AT command

[winning83]

I'm building a small app for PC like Nokia PC suit. I use 8210 and 6220 to test the app but there are some strange problems

1. Why Max of Name field in the response is difference from real phone? +CPBR: (1-250),20,8 -> is mean that Max of Name field is 8 characters but if I add an entry in phone, max of name field is 14 characters.

PC: AT
8210: OK
PC: AT+CPBS="SM" -> select SIM storage
8210: OK
PC: AT+CPBR=?
8210: +CPBR: (1-250),20,8
8210: OK

2. Why Nokia 6220 don't accept some AT commands (command related to phonebook?) -> is there AT command set for only NOKIA products ? because it is read by Nokia PC Suit in normal.

PC:AT
6220: OK
PC: AT+CMGI -> manufacturer
6220: Nokia
PC: AT+CMGF=1 -> set text mode
6220: OK
PC: AT+CPBS="SM"
6220: ERROR

3. With the same code to read phone book, ME first then SM later is okie but in opposite is not okie ??? In Vietnamese, there are 2 GSM network: Vinaphone and Mobiphone. I tested with Mobiphone SIM, it's okie whatever SM or ME read first, but if I test with Vinaphone SIM, it's only okie if I read ME first. -->> are there any different SIM types and its properties ?

oh, so you know what your doin...

[Jason Glass]

my 6630, doesnt even allow access, or doesnt reconize any of those commands, relating to pbook and storage, all i can do is send(not receive)sms.

bytes...and good luck!

I think my 6220 and your 6630 does not fully support AT command, so maybe Nokia products use Nokia's AT command like Sony Ericsson. I have an AT command set for Sony Ericsson, there are many commands are written for only Sony Ericsson. http://www.megaupload.com/?d=WN6XE65Q

I have a question:
Nokia 8250 can send/recive SMS through COM port?
Anybody, pls help me.
Thanks

[Jason Glass]

you just have to generally try to send the sms, follow the steps below, or search forums for other posts in relation to testing the sending of sms using com ports/hyperterminal

good luck

PS: if it does support it, you could always post back to hear, so we know the device supports it!
