Abstract
Communication apparatus having first communication device conformed to a first communication standard and second communication device conformed to a second communication standard different from the first communication standard. A control unit is coupled to the first and second communication device. The first communication device is capable of detecting whether or not another apparatus is disconnected from the first communication device. The control unit is capable of setting the second communication device in an active state if the first communication device detects that another apparatus is disconnected from the first communication device when the second communication device is in an inactive state. The second communication device is capable of being used to communicate with another apparatus when the second communication device is set in an active state, and is not capable of being used to communicate with another apparatus when the second communication device is set in an inactive state.
