I have a program on the arduino side and a visual basic program on the computer. When we run the program excluding the wireless (xbee) then everything works fine. As soon as we add in the xbee it amost never works. Every great once and a while it'll correctly receive the data. The RSSI light goes green on the xbee explorer board every time we scan a card but our program doesn't register that it's been received. What information do you need from me to give me advice on this?
