Ok, thank you for the clarification. > If the ActiveMessageC is included, then the radio is in the SLEEP > state which consumes 0.02 uA (not mA). Yes, I know, but the maximum accuracy of my multimeter is the mA. :( > So far so good. In both cases the MCU can enter sleep mode, so it > essentially does not consume energy.

In the NullC application I added a component at a time and the result was: - Without components: ~ 1.5 mA - With ActiveMessageC (1): ~ 0 mA (Rx sleep) - With (1) and SenderC/ReceiverC/SplitControl (2): ~ 18 mA (Rx on) - With (1), (2) and LPL (3): ~ 0 mA (Rx sleep) Unfortunately I can not see the awakening of transmission in the LPL because my multimeter is slow. First, in previous posts, I was totally confused because, with LPL, in the sleep period my multimeter showed 3 mA. This morning I discovered that this value is given by the PRINTF library. In fact if I compile the application with the flag: CFLAGS += -I$(TOSDIR)/lib/printf in the Makefile, then in the sleep period I have ~ 3 mA. Incredible! :) However, thank you very much for your time Miklos.
