1. A communication apparatus comprising:
- a first interface that is connectable, via a first network, to an electronic device that stores software subject to update;
a second interface that is connectable, via a second network that is different from the first network, to a server apparatus that stores update data for updating the software stored in the electronic device to which the first interface is connectable;
a first acquisition unit that acquires information regarding the version of the software stored in the electronic device from the electronic device to which the first interface is connected and stores the information regarding the version in a memory;
a second acquisition unit that acquires the update data from the server apparatus to which the second interface is connected based on the information regarding the version stored in the memory even when the first interface is not connected to the electronic device and stores the update data in the memory; and
an update unit that outputs the update data stored in the memory to the electronic device to which the first interface is connected even when the second interface is not connected to the server apparatus.

Abstract
A narrow-area IF is connectable to an electronic device. A wide-area IF is connectable to a server apparatus. A version information acquisition unit acquires information regarding the version of software stored in the electronic device. An update data acquisition unit acquires update data from the server apparatus based on the information regarding the version. An update unit outputs the update data to the electronic device. After outputting the update data to the electronic device, the update data acquisition unit acquires the information regarding the version of the software stored in the electronic device.

7. An electronic device that stores software subject to update, comprising:
-
a communication unit that is connectable to a communication apparatus that is connectable to the electronic device via a first network and is also connectable, via a second network that is different from the first network, to a server apparatus that stores update data for updating the software stored in the electronic device; an output unit that outputs information regarding the version of the software stored in the electronic device to the communication apparatus to which the communication unit is connected; and an input unit that receives the update data from the communication apparatus to which the communication unit is connected even when the communication apparatus is not connected to the server apparatus, given that the update data is acquired from the server apparatus in the communication apparatus based on the information regarding the version that is stored even when the communication unit is not connected to the communication apparatus, wherein, when the software is updated by the update data received by the input unit, the output unit outputs the information regarding the version of the software stored in the electronic device to the communication apparatus to which the communication unit is connected.
