I am new to arduino and have recently been able to parse gps data from my android phone through bluetooth interface. My goal is to parse two different sets of gps data from two phones and compute bearings to track each device. Is there a method to establish a protocol based on each phone so that i only need to have 1 bluetooth receiver.
android app used to transfer nmea data : nmea bluetooth access

looks like i the other solution is to have another BT module for the second source
That is correct. This means Android would be master and makes connection with Arduino in the normal manner.
I'm far from sure what the point of all this is, but if you proceed, I rather feel that you will need a GPS on Arduino. This may mean yet another serial port. In that event, I hope you are using a Mega, as this has four hardware serial ports.
