Send SMS with node js a Raspberry pi3 and a gsm module 900

GSM Module Communication Script

Description

This Node.js script communicates with a GSM module (GSM 900) using AT commands. The script is designed to send text messages to specified numbers at regular intervals.

Usage

1. Ensure that the required Node.js modules are installed. You can install them using npm install serialport.
2. Connect the GSM module to the Raspberry Pi's Serial Port 0 (/dev/ttyS0). Make sure the port is enabled on the Raspberry Pi.
3. Configure the baud rate in the script based on the requirements of your GSM module.
4. Update the numbers array with the desired phone numbers.
5. Adjust the message variable to contain the message you want to send.
6. Run the script using node your_script_name.js.

Script Structure

• The script uses the serialport module to communicate with the GSM module over the serial port.
• It sends a sequence of AT commands to the GSM module, including setting the text mode, specifying the recipient number, and sending the message.
• Each AT command is encapsulated in a promise to ensure proper sequencing, as AT commands require specific timing.
• The entire sequence is run every 60 seconds (setInterval).

Dependencies

• Node.js
• serialport module (npm install serialport)

Configuration

• Serial Port: /dev/ttyS0 (Make sure it's enabled on the Raspberry Pi)
• Baud Rate: 115200 (Adjust based on your GSM module requirements)

Notes

• Adjust the timing in the promises based on the response time of your GSM module.
• Ensure that the control character \032 (Ctrl+Z) is properly sent to submit the message.

##Things you need :

1.- raspberrypi3

2.- module gsm 900

3.- intall node in raspian or any OS you choose

4.- open Serial ports in my case in raspbian OS

4.- test it with minicom (google it)

5.- probably you will need to configure some docs in your raspberry (change baudrate)

6.- run the code
