I'm using the sources given in the virtual machine image provided by Shimmer, and according to the dates, it seems up-to-date.
Actually, I'm not 100% sure the problem comes from BaseStation. When I write on /dev/ttyUSB3 (the span is ttyUSB2 for programming and ttyUSB3 for data), the blue led blinks, but I put a *call Leds.led0Toggle()* that is supposed to toggle the green one (the orange/maroon only blinks while programming) in the uartReceive event. Did you ever use C for sending to the mote through BaseStation on span ? Coz' maybe something is going wrong before the BaseStation and make everything not work properly ... Any hints are welcome ... Thanks for your answer, Mike.
