What is GSM in microcontroller?
GSM is the acronym for Global System for Mobile Communication. GSM module is wireless modem that transmits data using radio waves. GSM architecture is similar to the mobile architecture. GSM modems are generally used in many electronic applications and they are required to interface with the microcontrollers.
How do you program a GSM module?
Booting the GSM Module!
- Insert the SIM card into the GSM module and lock it.
- Connect the adapter to the GSM module and turn it ON!
- Now wait for some time (say 1 minute) and see the blinking rate of ‘status LED’ or ‘network LED’ (GSM module will take some time to establish a connection with mobile network)
What is GSM modem and how it works?
A GSM modem is a wireless modem that works with a GSM wireless network. A wireless modem behaves like a dial-up modem. The main difference between them is that a dial-up modem sends and receives data through a fixed telephone line while a wireless modem sends and receives data through radio waves.
Which command instructions are used to control a GSM modem?
That’s why modem commands are called AT commands. Many of the commands that are used to control wired dial-up modems, such as ATD (Dial), ATA (Answer), ATH (Hook control) and ATO (Return to online data state), are also supported by GSM/GPRS modems and mobile phones.
Where do we connect the pin of GSM module to microcontroller 8051?
Here the GSM module and the microcontroller communicates in between using serial communication. Rx pin of the 8051 is connected to Tx pin of the GSM module and Tx pin of the 8051 is connected to the Rx pin of the GSM module.
What is GSM module in simple words?
A GSM modem or GSM module is a device that uses GSM mobile telephone technology to provide a wireless data link to a network. GSM modems are used in mobile telephones and other equipment that communicates with mobile telephone networks. They use SIMs to identify their device to the network.
What is GSM command?
These are supported by modems like mobile phones, GSM or GPRS. There are some commands which support GSM. These commands which are used for GSM mainly include SMS based commands like AT+CMGS, AT+CMSS, AT+CMGL & AT+CMGR. Here the prefix AT in these commands informs the modem regarding the begin of a command line.
