I am very new to GSM/GPRS modules. I am trying to make a project where a SMS/CALL needs to be sent to a mobile number.

My questions are very basic, would be really grateful if someone could deal that.

1. Can the SIMCOM GSM/GPRS modules be programmed as we program MCUs like AVR or PIC? or they can only controlled by AT commands or LUA?
2. Can I use such module without any controller if I have the chip? I went through the H/W design of SIM900, I found there are GPIOs, ADC, Communication port like UART, I2C etc -- as we have in general MCUs.
3. I have been searching the SimDevIDE, is it for programming the chip?
4. How to start with this module/chip? Any simple tutorial for a beginner like me?

Regards
 

SIMCOM modules are not programmable like MCUs(AVRs , PICs etc).
AT commands are the basic form of communication to these modules.
Some SIMCOMs can use HTTP HTTPs also.

Though they have GPIOs, ADC etc , you can access through AT commands only.

SIMCOM GSM/GPRS Modules are peripheral modules only.

They are not usable like MCUs. Given the proper commands , they can be used a standalone unit.

(As a sidenote , these SIMCOM peripheral modules have ARM controllers inside for controlling the communication network and interfacing...)
 
Thanks srzibf, last one query for now, for what the SimDevIde stands for then? I can go on programming SIMCOM chips without this IDE?

Regards
 

SimDevIDE is an integrated pgmming environment for all SIMCOM modules .
you can download the commands to the specific modules usin SIMDEvIDE.

You can start programming SIMCOM chips without SIMDevIDE.
 

You can use a simple arduino board to communicate with simcom module. You can use sim900 if you only need call/sms. Or you can go for sim908 if you want to use gps too. The module can be interfaced through the serial port of arduino/mcu and communicate via AT commands
