Hi Janos, Yes, I already did that according comments of another (older) thread. The consumption is above 10 mA when the radio is on, but when I turn off the radio and the UART, then the consumption drops to 0.4 mA. ActiveMessageC is included, but not wired. I've got my radio code wired to RF230ActiveMessageC instead.
I wonder whether there's a similar situation with the ADC and whether I need to include SomeADCComponentC to achieve the same result. Also, I know that at least one of the UART ports is off for sure, but I can't tell whether the USART port that I use to program the device via ISP is off as well.
