Chess station portable -- 2

Hi

I need to work with someone who has knowledge of Raspberry Pi hardware.
I am building a human vs human chess station, where 2 Raspberry Pi w 0 are used.
Each Pi will have a 3.5 inch lcd touch panel for inputting the moves with a stylus.

Now the 2 Pis have to send and receive moves to eachother and this will be done over bluetooth.

We will be using Qt creator for the gui.

Thanks
