How can I get 2 XBee S1 modules to communicate with each other not using a laptop just using 2 FPGA boards through UART?
I can get them both talking with the Grove boards both attached to a computer.
However my task is to get 2 XBee modules transmitting data between 2 Digilent Nexys2 FPGA boards. I have setup all the UART vhdl code for transmitting just between the DOUT, DIN pins supplying 3.3V and ground to the appropriate pins. I am just trying to transmit a hex 55 from one module to the other. So I have put a scope on my DIN pin and I can see the transition showing hex 55, but I can’t get the other XBee S1 device that I currently have hooked up to my laptop to receive the hex 55 data using the XCTU software? I can search the remote devices and find the XBee attached to my FPGA board, but it just says “Could Not Initialize device” Any suggestions? I mean this seems like it should be straight forward I just need to transmit one byte from one board to the other board. Any suggestions?
Thanks!
