Low power adaptive power control

A wireless device, comprising:

• one or more processors;
• and
• a memory coupled to the one or more processors and storing processor-readable code that, when executed by the one or more processors, is configured to:
• transmit, at a transmit power level, a plurality of audio packets over a Bluetooth connection to a peripheral device paired with the wireless device;
• receive one or more NACK frames over the Bluetooth connection from the peripheral device, each NACK frame indicating a number of the transmitted audio packets that were not successfully decoded by the peripheral device;
• obtain a percentage of the plurality of transmitted audio packets that were not successfully decoded by the peripheral device;
• obtain signal strengths of one or more audio packets of the plurality of audio packets transmitted to the peripheral device;
• and
• selectively adjust the transmit power level based on the percentage and the signal strengths.

A wireless device, comprising:

• means for transmitting, at a transmit power level, a plurality of audio packets over a Bluetooth connection to a peripheral device paired with the wireless device;
• means for receiving one or more NACK frames over the Bluetooth connection from the peripheral device, each NACK frame indicating a number of the transmitted audio packets that were not successfully decoded by the peripheral device;
• means for obtaining a percentage of the plurality of transmitted audio packets that were not successfully decoded by the peripheral device;
• means for signal strengths of one or more audio packets of the plurality of audio packets transmitted to the peripheral device;
• and
• means for selectively adjusting the transmit power level based on the percentage and the signal strengths.

A non-transitory computer-readable storage medium storing instructions, that, when executed by one or more processors of a wireless device, cause the wireless device to perform operations including:

• transmitting, at a transmit power level, a plurality of audio packets over a Bluetooth connection to a peripheral device paired with the wireless device;
• receiving one or more NACK frames over the Bluetooth connection from the peripheral device, each NACK frame indicating a number of the transmitted audio packets that were not successfully decoded by the peripheral device;
• obtaining a percentage of the plurality of transmitted audio packets that were not successfully decoded by the peripheral device;
• obtaining signal strengths of one or more audio packets of the plurality of audio packets transmitted to the peripheral device;
• and
• selectively adjusting the transmit power level based on the percentage and the signal strengths.
