# How to communicate with 2 devices with 1 UART MCU in AVR

I am currently looking to integrate GSM SIM900 and GPS Module with Atmega32. As atmega32 has 1 UART option, I was just wondering that can I connect these two devices with single UART. I am making a simple GPS tracker which will send a GPS Lats Longs to user mobile whenever a user ask for it.
