I am doing a project where i need to get data from remote zigbee and process the data using zigbee at another end using fpga. I need to do serial communication with zigbee and fpga. I am confused how to start about it. Please if any one can help me in this, I would really appreciate it.
Thank you

P.S I have to use nb3000 board and zigbee is xbee s1 and i am using altium designer 10.
