GSM interfacing to MCU

[varsha]

hiiii,

Is it possible to interfaced GSM with the Microncontroller without using Rx/Tx…??

instead of this can we use I2c or SPI protocol  ??

kindly suggest me any information regarding this or else study data …

 

 

thanks

It depends on the GSM module you are using..Like sim900d supports spi. You can check the datasheet of the sim module.

But best suggestion is to use Tx/Rx.
