How do I send an Arduino GSM Shield command?

Sending a text message (SMS) –AT COMMAND

  1. Install GSM shield in Arduino board and connect power cord.
  2. Open your serial monitor program (I use SSCOM)
  3. Through your serial terminal software, send AT+CMGF=1 and press the Enter key.
  4. Send AT+CMGS=”+966XX6541231″ and press the Enter key (include the quotes).

What are AT commands in Arduino?

The following AT commands should be written in the Arduino’s serial monitor (in order) to program the ESP8266:

  • “AT” This will check if the module is connected properly and its functioning, the module will reply with an acknowledgment.
  • “AT+RST” This will reset the wifi module.

How do you power a GSM module?

Both 1.8 volts and 3.0 volts SIM Cards are supported by SIM900A – the SIM card voltage type is automatically detected.

  1. Assemble GSM Antenna to the modem.
  2. Connect serial cable to the modem.
  3. Give power supply in between 4.5V to 12V through the power jack provided.
  4. Default factory Baudrate is 9600.

What is GSM module for Arduino?

The Arduino GSM shield allows an Arduino board to connect to the internet, send and receive SMS, and make voice calls using the GSM library. The shield will work with the Arduino Uno out of the box. The GSM library is included with Arduino IDE 1.0. 4 and later.

How do I run an Arduino command?

Open up your Arduino IDE, choose the correct serial port (if needed), open the serial terminal, choose the baud-rate that the other device operating on, send your AT commands by just writing them and hit enter.

What is at command in Bluetooth?

AT Command Mode. AT command mode allows you to interrogate the Bluetooth module and to change some of the settings; things like the name, the baud rate, whether or not it operates in slave mode or master mode. When used as a master device AT commands allow you to connect to other Bluetooth slave devices.

How do I connect my Arduino to my SIM card?

Push the SIM to the board and slide the metal bracket towards the edge of the shield to lock it in place. Once the SIM is inserted, mount it on top of an Arduino board. To upload sketches to the board, connect it to your computer with a USB cable and upload your sketch with the Arduino IDE.
