[Tinyos-help] Hi about the Battery monitor function in RF230

2008-08-20 Thread
Hi, there For my experiment, the RF transmission power control is important. And the battery voltage may drop all the way as the time elapses, I'm wondering whether the transmission power can be inflected by the battery drop? or it doesn't matter in a certain voltage range. I know there is a
