Abstract:
1. A method, comprising: transmitting, by a polling device, short-range wireless polling signals via a near field communication (NFC) or radio frequency identification (RFID) communication short-range wireless interface according to a first poll interval, and receiving short-range wireless response signals from responding devices responding to the short-range wireless polling signals; determining, by the polling device, whether the polling device is in an active mode or in an inactive mode, wherein the inactive mode comprises at least one of a stand-by mode, low power mode, idle mode, or sleep mode state; when the polling device is determined to be in the inactive mode, causing the polling device to enter into a polling mode for transmitting short-range wireless polling signals via the short-range wireless interface according to a second poll interval that may be the same or different from the first poll interval, if the polling device is receptive to being charged by a wireless charger near to the polling device; and discarding, by the polling device, received short-range wireless response signals from responding devices responding to the short-range wireless polling signals having the second poll interval, so that polling response signals received from a nearby wireless charger, do not activate an operating system of the polling device.
