Automatic power-off of bluetooth device from linked device

摘要

Methods and systems for powering-off a Bluetooth device from a linked device are provided. A device can transmit a Bluetooth signal to a linked device to instruct the linked device to power-off. In this manner, the user need only turn off one device manually which results in all linked devices being powered off. This process can be initiated by a user through a device directly linked with the device to be powered-off or through a device that is indirectly connected, through one or more Bluetooth networks, with the device to be powered-off. This process can also be automatically initiated by a device when a set of predetermined conditions exist. Once instructed to do so, a device can initiate a predetermined power-off process which can involve terminating any ongoing functions and turning off various subsystems. In accordance with the present invention, a user can initiate a power-off of all the devices on a Bluetooth network through a single device.

1. An electronic device, comprising:
a Bluetooth transceiver; and a processor configured to:
automatically initiate a power-off process of the electronic device if a battery level in the electronic device goes below a threshold; andtransmit a signal, in response to the initiating, to a second electronic device according to a Bluetooth communications protocol via the Bluetooth transceiver, wherein the signal includes an instruction to cause the second electronic device to initiate a power-off process of the second electronic device.
