Gsm(sim300) and GPS(gtpa010) interfacing together using AVR microcontroller

[Pravin Poudel]

Anybody please  help me to interface sim300 and gps module using avr microcontroller.I want to send the date given by GPS module through sms and display that data to the 16×2 lcd.

Hi Pravin,

Which AVR microcontroller are you planning to use? Most of the microcontrollers have only one serial port and hence to connect two serial devices like SIM300 and GPS you have to use switching techniques on the modules, and as far as I know that is the only complexity in your project.

You can find seperate projects on interfacing SIM300 and GPS with AVR under the section 

EG LABS > MICROCONTROLLERS > AVR

Hope you find them helpful.

I’m going to use atmega 16 for this project.I hav tried it but it didnt work so would you please send me source code for this.

Hi Pravin,

I guess all the AVR projects in this site is build around ATMEGA16 itself.

sir,

would you please help me to check whether gps is providing the data or not whithout displaying it on lcd?If gps provides the data( ie lattitude and longitude)then we have to send sms through gsm module.How to modify the code of gps interfacing using avr  to solve this problem.I’m going to use atmega 16 and gtpa010 gps module.
