Hi,
Is it possible to use on Edison 2 devices that uses UART tx rx? I know on Edison we have 1 TX 1 RX. But what if i want to use GROVE GPS and GROVE GPRS at the same time, is it possible to 'emulate' GPIO pins as TX RX pins?
And if yes, is it difficult?
Thanks!

The Edison has 2 Serial ports.
If you disconnect the USB-to-Serial FTDI chip, you can connect 2 Serial devices.
Otherwise, an UART-to-I2C adapter could be easier to use. It's essentially Arduino with two ports. I don't know if it needs programming and I'm not sure about the voltage level. The Atmel microcontroller should work on 1.8V.
