As you might have figured it out from the list archives: you need to
measure the power consumption with some external equipment.

You can use SplitControl to turn the radio on and off. When the radio
is turned on, it will be receiving. Since the transceiver can't send
and receive at the same time, the radio won't be receiving while
sending a message. Once a transmission is over, it will be receiving
again. The radio won't go to sleep unless you explicitly call
SplitControl.stop().

It's a different story if you choose to use low power listening. You
can read about that at
