Hi again, I am running Oscilloscope on the Invent. Actually, I modified it days ago to get temperature readings.
In the configuration of OscilloscopeAppC, I put new SensirionSht11C() as TSensor in and take new DemoSensorC() as Sensorout. I also changed OscilloscopeC.Read -> Sensor to OscilloscopeC.Read -> TSensor.Temperature The other things were kept unchanged. When I ran the SerialForwarder, I always got 65535 for the readings. After being through the code in OscilloscopeC.nc, I found that 65535 is set by the Read.readDone() event in case of unsuccessful data read. Moreover, LEDs were not working. Two motes gave me the same results. My current guess in that I might not activate the temp sensor correctly. I have one reply saying that Invent may not be supported by TinyOS 2.x. I'm using TinyOS 2.x, Tmote Invent (as sensor), Tmote Sky (as base station), Windows XP & cygwin.
