A client repeatedly transmits a firmware request including an obtaining start address and an obtaining data length. The obtaining start address indicates the first address of firmware data to be obtained from the server by the client. The obtaining data length indicates the length of the firmware data to be obtained from the server by the client with respect to each firmware request. The server receives the firmware request from the client repeatedly and returns the firmware data for the obtaining data length from the obtaining start address with respect to each firmware request. The client further obtains the firmware data returned from the server repeatedly and updates the firmware by using the firmware data obtained from the server.
