How do you make a call with GSM?

How do you make a call with GSM?

Follow following steps and AT commands to configure gsm module to make call:

1. ” AT+CHFA = 1″ This command is used to select Audio channel.
2. “AT+CMIC = 1” This command is used to select gain of Audio. Its value can be between 0-15.
3. “ATD092341434445” This command is used to make call to required number.

How do I connect my GSM module to my phone?

Booting the GSM Module!

1. Insert the SIM card to GSM module and lock it.
2. Connect the adapter to GSM module and turn it ON!
3. 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 connection with mobile network)

How does a GSM / GPRS module work on a cell phone?

Wireless MODEMS are also available for different cellular networks like CDMA, GSM, UMTS and LTE and different data services like GPRS, EDGE, HSDPA and LTE. A GSM/GPRS Module is an IC or chip that connects to the GSM Network using a SIM (Subscriber Identity Module) and Radio Waves.

What do GSM and GPRS stand for in a microprocessor?

A GSM GPRS Module is used to enable communication between a microcontroller (or a microprocessor) and the GSM / GPSR Network. Here, GSM stands for Global System for Mobile Communication and GPRS stands for General Packet Radio Service.

What are the radio frequencies of a GSM module?

The common radio frequencies in which a typical GSM Module operates are 850MHz, 900MHz, 1800MHz and 1900MHz. Since it is not possible to interface a GSM/GPRS Module directly to an external device like a microcontroller, we need a setup like shown in the following image.
