hi how get sim card balance by gsm/gprs A6 module? I used the following AT, but does not work and result in unreadable characters or numeric code. note : my sim card language is English. I used all four AT+CSCS that is supported by A6.but I can not get +CUSD: "English-message". why? AT commands: AT+CMGF=1 AND/OR 0 AT+C
Hi, What code do you need? gprs modules often communicate via UART, but it could be any other interface, too. code for sending and receiving data with a UART? Or do you need to know the gprs commands? How do you want to process the gprs data? Storing in memory, showing on a display, transmitting to a PC? (...)
hey we have an ongoing project and that need to have an important application that is firmware upgrade over the air. we are using Atmega 128 which having two UARTS. two options to get connected with internet are (RN171)WiFi and SIM900A(gprs). i saw a website on which the user upgrade the Arduino firmware using ESP8266(Wifi module). [U

SIM900 command runs without any problems on a network with apn, a number of directives not implemented on SIM900 and it is impossible to connect to the network. Of course, if a sim900 previous code was not performed previously on the new rules apply at work without any problems. Because of the large number sim900 I use so I can not change all of ou
Hi guys, I have setup a TCPIP connection between my ITEAD SIM908 development board and a server on my PC(SocketTest v3) using the following code: AT+CIPSHUT AT+CIPMUX=0 AT+CIPSTATUS AT+CSTT="internet","","" AT+CIPSTATUS AT+CIICR AT+CIPSTATUS AT+CIFSR AT+CIPSTATUS AT+CIPSTART="TCP","","
Hi all, I am using HTTP GET method to transfer few bytes of data to a web page, Now it takes 10-12sec for the modem to transfer data to webpage. Is it possible to upload data within 1-2sec ?, so that i could send more samples to webpage. The commands which i am using: // for initializing AT+SAPBR=3,1,"Contype", "gprs" AT+SAPBR
I have an Arduino in a remote location and would like to upload new code via gprs (a SIM900 is connected to the Arduino via TX/RX serial interface with hardware handshaking (DTR, CTS, RTS connected)). I was thinking about putting the .hex file (or some format) on a webserver and Arduino will automatically check once a day if there is a new sketch a
How can I reset SIM900 ? I am making a library for SIM900 GSM/gprs communication. I want to implement reset function in the code. One function will be to send AT Commands. I need to implement reset function inside this function. It sends AT Commands 3 times to SIM900 and if SIM900 responds with ERROR or if it doesn't respond for 3 times then the

never attempted FTP using a SIM908 but have a look at there appears to be code for connecting to FTP using a SIM908 it may give you some ideas
I use SIM900D module and interface it use software. I write that software code use VB 6.0. But I face a problem. If a incoming call in my gprs module that time my module send ?RING? string. I see it a text box. But I want to do that when my RS232 receive ?RING? that time does something like as Beep. My software work normally but when my module send
The first thing to do is to know the gprs module and its management commands, you already did that? Then u need to choose a microcontroller to manage the gprs module and then choose a language to the development of the code. Do you know any? Have an idea in mind about what to use microcontroller (I usually use PIC). Please answer these (...)

I think that 100% sending data at 1s isn't possible over gprs and not over HSDPA ...... Yes speed is high but not allways! You must search for AT commands in user manual for permenently gprs connection! If you attach code maybe someone can help you!
Unfortunately, I am not familiar enough with BASCOM or any other variant of Embedded BASIC to be of much help in composing the required code. However, I would suggest attaching your GSM/gprs module to your PC's serial port and using a terminal emulation software like Putty to test and troubleshoot the required AT Command sequences. Once y
