Abstract:
A wireless communication apparatus includes a first control unit operating with power supplied from a secondary battery and operable in a case where a detected voltage of the secondary battery is greater than or equal to a second threshold voltage, a second control unit operating independent from the first control unit and with power supplied from the secondary battery, and a wireless communication unit controlled by the second control unit operating with power supplied from the secondary battery to communicate with a different wireless communication apparatus, wherein, in a case where a detected voltage of the secondary battery is lower than a first threshold voltage that is lower than the second threshold value, the second control unit ends transmission of a packet and communication connection.
