Hi, I'm working with several IRIS modules and Tinyos-2.1.1 and I have a problem with the Low Power Listenning and radio stack for the transceiver RF230. Specifically, my problem is that by using the LPL mode that offers TinyOS-2.1.1. I have seen with the use of an oscilloscope that does not turn off the radio oscillator, and the state does not really change to the radio SLEEP state (but the pin SLP_TR change between high and low state), and even using periods of duty cyle small enough to appreciate the changes of state of radio in the oscilloscope. To test this, I have been analyzing the component RF230DriverLayerP (tos/chips/rf2xx/230) which implements part of the internal state machine RF230 radio (here there is a function called changeState turn on/off the radio), and everything seems to be correct. Also, I have checked that in TinyOS-1.15 with Moteworks and the same iris modules, the Low Power Listening turn off the radio and the oscillator in order to the duty cycle configurated
I' don't know because the component RF230DriverLayerP does't switch off the oscillator, when the function changeState() is called.
