How to send data from GPRS to GSM module?

How to send data from GPRS to GSM module?

Process of Sending Data from GPRS of GSM Module is easy. Here in this project, we are sending some string or words to the server by typing using keypad. Same string or word will appear over the LCD, then press D/OK to send the input string to the server.

How to send data to web server using Arduino?

Check the full code at the end of the article. For Sending Data to SparkFun Server, we need to interface Keypad and GSM module to Arduino. In this project we have used Arduino to taking input string from the keypad and sending commands to GSM/GPRS module. GSM/GPRS is used to communicate with the Internet for sending data to the Sparkfun server.

How is the GSM module connected to Arduino?

GSM Module’s Rx and Tx pin is directly connected with Arduino’s pin D3 and D2 respectively (Ground of Arduino and GSM must be connected with each other). A 16×2 LCD is used for displaying input strings and showing welcome message and data sending status as well.

How to send data to web server using sim900a?

This is an IoT based project in which we will use GPRS, present on the GSM Module SIM900A board, to send some data to the web service on the internet.

How to interface GSM sim900a with Arduino D9?

You have to connect GSM’s 5VT to Arduino D9 and GSM’s 5VR to Arduino’s D10 for serial communication between arduino and sim900a module. 1. To change sms sending mode : AT+CMGF=1 2. To read SMS in text mode : AT+CNMI=2,2,0,0,0 3. To make a call : ATD+60XXXXXXXXX; //replace X with number you want to call, change +60 to your country code 4.

Where is the TTL pin on Arduino sim900a?

If you hear a ring back, the gsm module has successfully established network connection. You can see a TTL pin with 3VR, 3VT, 5Vr, 5VT, VCC and GND on your sim900a near your power supply pin. You have to connect GSM’s 5VT to Arduino D9 and GSM’s 5VR to Arduino’s D10 for serial communication between arduino and sim900a module.
