sim508 gprs

Hi _Demon

To get the TCP packet that is transmitted from the SIM508 GPRS modem, you need a public IP address and a socket server program (writen in winsock for example, there are many examples on the internet).

I suggest the following steps:

_ Setup the ADSL modem to open a port, and forward it to the PC that running the socket server application (setup the NAT option or Virtual Server option).

_ Turn off any security program (Bit Defender, Kasperski Internet Securyty, ...)

sim508 application notes

I am also thinking of using SIM508 in a project. Does the GPS and GPRS perform well? Is it easy enough to learn and most important, how is availability and cost?

Thanks for much....

sim508 gprs connection

Good morning

My name is Moraali. I am having a problem for a year. It is simple, but I am not sure how to rectify it.
In brief, when I connect my chip (Xilinx FPGA) with SIM508, SIM508 does not send any SMS. When I tested the chip and the SIM508 separately, it work fine. But when I connect them together , it fails.

For more details, please refer(click on it) to this, it will give a detail explanation of my problem. At first you might have difficulities, but in the end you will understand. Please read, it simple.

http://forums.xilinx.com/xlnx/board...&thread.id=8677&view=by_date_ascending&page=1

Please reply to me as soon as possible.

Thank you.

OK, your other post is VERY LONG and convoluted, so I didn't take the time to read through the entire thing. However, one question - Are you sending a CTL-Z after your message? You need to send this to indicate the end-of-message.
 

send data from sim508

Hi

I used SIM508 Eval board long time ago about 3 years
Now I can't find the cables and the power supply.
My Question are:
Is any cross serial cable can work?
What should be the settings for flow control and budrate is 115200,8,N,1 with HW flow control OK?
what's the requirements for power supply is 5V@100mA enough?

I am using simcom 300 module with an eval board.

I am able to connect to a tcp server on a public IP but not able to send or receive data to/from TCP server.

After i connect to the server my module just "hangs" and does not take any further inputs.

I am using a USB to serial converter and running AT commands on hyperterminal.

What can be the reason.
