Systems and methods for managing power consumption of a transceiver

A Bluetooth device comprising:

• an antenna that receives analog radio frequency (RF) signals;
• a RF analog circuitry that receives and processes the analog RF signals from the antenna;
• an analog-to-digital converter (ADC) that receives and converts the processed analog RF signals to digital RF signals;
• a digital circuitry that includes a RF power detector that receives the digital RF signals and determines a RF power of the analog RF signals from the antenna based on the digital RF signals;
• and
• a computing device that instructs the RF analog circuitry to operate during page scanning and/or inquiry scanning, the computing device being designed to receives the RF power of the received analog RF signals and manages the power consumption of the Bluetooth device based on the RF power, wherein the computing device is designed to reduce current to at least some or all electrical components in the RF analog circuitry to their respective minimal current limits during the page scanning and/or the inquiry scanning based on the RF power.

A method that is implemented by a processing device, memory having a power manager that includes instructions executed by the processing device, the instructions comprising the following steps:

• performing inquiry and/or page scanning at a transceiver;
• instructing a radio frequency (RF) analog circuitry to operate in during the page scanning and/or inquiry scanning;
• determining whether a RF power in the analog RF signals was detected;
• managing the power consumption of the transceiver based on the RF power;
• and
• reducing current to at least some or all electrical components in the RF analog circuitry to their respective minimal current limits during the page scanning and/or the inquiry scanning based on the RF power.
