Hey you all, I have a question of the unit of RXThreshold. Is it in 'mW' or 'Watts' ? >From the manual, the unit should be in Watts. However, in my simulation, the communication range is too large when I use the RXThreshold value in Watts. (The receiver is too sensitive.)... Thanks in advance for any help.
