Actually, you need to understand some points on server side. A server will run an instance that will listen to defined port (22 for ssh, 21 for ftp, 80 for http) like that and for socket based connection like TCP will establish a virtual link between the server and client, with a unique channel (which used to differentiate (...)
Hello Everyone ! I have experience in working with PIC Microcontrollers and I want to send data (simple text) from PIC to the internet on HTTP protocol. I will be interfacing SIM900D GSM/gprs modem with PIC for this purpose. Can anyone guide me about this interfacing and uploading the text using HTTP protocol ? What are the (...)
@Jayanth, Now i got a clear picture of what you are trying to do... There are many things you have to consider and also the necessary actions to be taken... 1. SMS handling 2. PDP DEACT - In case of IP lose 3. gprs activation handling --- if it fails then what to do next? 4. TCPIP connect and (...)
I have interfaced ATMEGA2560 Microncontroller with SIM900B modem. I have successfully Tested modem, registered to network, got good signal strength ( 25/31), connected to gprs connection, checked the IP address, saved the ftp server parameter and successfully uploaded file to ftp server. Everything is working smooth but (...)

Hey, did u attach your module to gprs using at+cgatt? and did u open bearer profile using at+sapbr before executing at+ftpget?
There are two problems involved with your attempt to talk to the ftp server: - you don't use legal ftp commands. Refer to RFC 959 or any other specification to learn the ftp syntax. - ftp uses separate command and data channels. Without connecting a second port for the (...)
No, i think you should have modem with rs232 support and a controller which is programmed to communicate with modem using AT commands. you can put files to ftp server using gprs facility. you could go for simcom 300 modules or wavecom modems which has good support......

Do you intend to use gprs at the server or the client side? The mobile internet provider possibly won't allow inbound connections.
- I guess, you'll need to login as anonymous - You need to open a second (sata) port for ftp transmission. Is this option supported by your gprs modem?
