NFC-ENABLED CONSTRAINED DEVICE, NFC-ENABLED CONTROL DEVICE, AND METHOD THEREOF

摘要

A Near-Field Communication (NFC)-enabled constrained device (100) is provided. The constrained device (100) comprises a processing circuit (111) operative to implement a functionality of the constrained device (100), an NFC-interface circuit (115) configured to harvest power transmitted by an NFC-enabled control device (200) and to enable exchange of data with the control device (200), when the devices are in proximity, and a restart circuit (121) configured to accumulate electrical charge using the harvested power received from the NFC-interface circuit (115), and to trigger restart of the processing circuit (111) when the accumulated electrical charge exceeds a threshold level. Further provided is an NFC-enabled control device (200) for restarting the NFC-enabled constrained device (100). The control device (200) comprises an NFC-interface circuit (215) configured to transmit power to the constrained device (100) and to enable exchange of data with the constrained device (100), when the devices are in proximity, and a processing circuit (211) operative to initiate the transmission of power to the constrained device (100), and to control the exchange of data with the constrained device (100).
