====== Transmit (Tx) Power ======

Bluetooth power is expressed in Decibel-milliwatt (dBm), the unit used to measure radio frequency (RF) power level. For a Bluetooth device, 0dBm is the standard power level and +4dBm is just over a doubling of power. -3dBm will be half power, -6dBm will be a 1/4 power and -9dBm 1/8 power. Each change in ±3dBM is a doubling/halving of power.
