Hello Friends,

I'm looking for low cost GPRS Module to connect my server (listening tcp port 2256) written in Delphi over internet with PIC18LF4620.

- What kind of module do I need for this (or be enough)?
- What should I know at PIC side as software? I'm using hitech C and I can easily send and receive any data over its UART.
- Which gprs module do you advice me to start my project, it should be stabile and cheap.
- Where can I buy a module immediately?

Have you used this module before?
Will I need any software stacks implementation with this?
Is it working stable ?
What is the difference between GM862-PCS and GM862-GPRS?
What is E-GSM 900/1800 MHz and E-GSM 900/1800/1900 MHz?

What about SIM100S32-E?
It's only 35$ and has embedded TCP/IP stack.
Anyone used it before?
Is It wotking stable ?

They have written SIM100S had "An embedded powerful TCP/IP protocol stack"
But someone said It isn't so. Anyone test it? Do we need software implementation for PPP and TCP/IP stack?

Yes, SIM100S32E has got a TCP/IP stack. Also one dosent need to write a PPP stack. Iam using it it is working fine.

For example, How can I send my nick name "BasePointer" as string to a server that listens TCP port numbered 2256 with SIM100S32E after all communications procedure? Can you show us that with one line AT command?

You can to probe with MC56, Siemens module
It had two way to access to internet:
1- Using functions or commands GPRS with a external stack TCP/IP
or
2- Using functions or commands to access to Internet with internal stack TCP/IP

BasePointer wrote:

This cannot be done in a single AT command.
A series of steps have to be followed.

Step 1:AT+CGDCONT=1,"IP","<apn>"
<apn> - This is the apn given by your service provider
Step 2:AT+CSTT = "<apn>","<username>","<passwd>"
Step 3:AT+CIICR
Step 4:AT+CISFR
Step 5:AT+CIPSTART="TCP","<IP address of your server>","port No"
In your case port no will be 2256
Step 6: AT+CIPSEND=<data to send> CNTRLZ
In your case data to send will be BasePointer.

In the server there should be a server socket program listening in 2256 port .

Does the TC65 has a built in TCP/IP stack?

I can't seem to find a list of AT Commands for Nokia (6310i) for GPRS. Does anyone have them?

Best regards,

I dont think you will get a readymade solution for MC35. What is your application

TCP = you are sure all your data is received
UDP= you are not sure all data is received

TCP protocol is designed for reliability. It has several states (closed, open, listen). Several packets are sent in both ways in order to change the state. After a connection is established, for every data packet sent in one way, there is an acknowledge packet sent back. This is used to control the reliability of the transmission. If one side does not receive an acknowledge for a packet (packet was lost), it will retransmit it after a time. However, this has its costs, the traffic will be increased with the control data.
On the other side the UDP protocol is designed for speed. There are no connection states, and a packet is sent without expecting any kind of confirmation. The packet may or may not arrive at the destination, and the sender has no way to be aware of this. This is appropriate for data where you can afford some losses (ex. video streaming).

For PC side, you have to write an application using socket communications. Fortunately, a lot of languages provide a socket interface to send receive data via TCP /IP. And there are a lot of examples out there that do that.

It is quite easy in VB6. Many working examples out there. For an intro, have a look at the following. For additional, seatch for "VB6 sockets"
