pcm in gsm module

So many guys are advertising Simcom modules. I guess there is somebody from original monufactorer side. So my question directed to him if he is here:

I have asked Simcom for MOQ information and price but did not get the result. It is not a good way to make a business . If you would like to sale your product you have to be responsive to any equiries, as it is means of advertising of product in indirect way.

This is true for most of the China based companies i had a chance to have contact with. Except Honestar was helpfull enough , but still there is delay with Confirmance statement approval from them.
 

benq gsm module schematic

i was directed to Excelpoint Systems which is the distributor for SIMCOM modules when i was asking for quotations from simcom.

You may contact Mr. Chin from Excelpoint Systems Pte Ltd at chin.tuck.keong@excelpoint.com.sg

Added after 1 hours 56 minutes:

Hello...

I having problems of connecting the module to the Server Software.

It always replies with connect fail.

I think the problem lies on the Server software. IP address shown on the Server software is 10.10.1.83.

How does the Server software generate a IP address?

Is it related to the PC's IP address?

I am very confused. Pls. enlighten me.

Thanks in advance.

IP is assigned by network dynamically or can be provided static . Dependent on operator. Also many of operators do not allow incoming socket establishment from internet to mobile devices and put firewalls to discard such requests .
Ask your operator customer care tech people for details .
 

gsm to pstn schematic

Hi Artem,

i have tried to connect my computer to a Internet Server provider through a dial-up modem.

the Server software is able to run in the computer.

i think the computer must connected to the internet server provider directly through a internet modem. No router must be in between the computer and the internet modem.

but i still find it very weird.

Can you recommend me any web-server or server software to test?

Thanks in advance.
 

sony ericsson+gsm modem+gr47+datasheet

Thisw is very different - for dioal up you use circuit switched call type and your poerator charges you per every second regardless the traffic is there. For gprs based connection in our country they charge for traffic amount regardless of connection time.

I suppose there is no server software you can use for relaying directly. Anything should be adopted for your need. In internet there are examples of server source codes - you can start with them and use ethereal for packet sniffing .

Has anyone used the SIM300D module? It's a SMD module, so there no soldering of a connector. I'm going to design a board for it if anyone is interested. Mike
