How accessible for this chip is its application software? Is it possible and in what measure to modify its behavior? For example, "TX power level setting" has 15 values, and for "15" the TX power is set to 1 dBm. Is it possible to set the TX power to a lower value e.g. -20 dBm or -30 dBm? Can the power consumption be adjusted by having the chip transmit only under user program's control. The purpose of all this is to minimize the average power consumption of the chip by adjusting it duty cycle or some other way.
