Description

  The present invention relates to a wireless transmission device externally attached to an interface of a personal computer. In particular, a nonvolatile memory is built in the wireless transmission device, and when the wireless transmission device is externally attached to the interface of a personal computer, the nonvolatile memory A wireless transmission device that writes the setting items for setting the operation of the wireless transmission device, and then causes the personal computer to operate the wireless transmission device according to the setting items of the wireless transmission device when the wireless transmission device is externally attached to the interface of the personal computer. About.

  Generally, there is a type of wireless transmission device such as a Bluetooth device that is used by being externally attached to a personal computer interface. For example, a device that is externally attached to a USB interface is called a USB dongle, and is a UART interface. Those used externally are called UART dongles. And when these dongle type wireless transmission devices are externally attached to the interface of a personal computer, as an optional function, the wireless transmission device is set to a predetermined operation state, for example, transmission power control or Some have a function that can be set to a power-saving operation by controlling whether or not the LED is lit.

  In this case, in order to use this optional function in the wireless transmission device, the operation setting items of the wireless transmission device are installed in advance on the personal computer side, and the wireless transmission device is externally attached to the interface of the personal computer. The operation setting items of the wireless transmission device need to be read from the personal computer and written to the internal memory of the wireless transmission device. When the operation setting items are written to the wireless transmission device, The wireless transmission device is operated according to this setting item. The operation setting items written in the internal memory of the wireless transmission device are inevitably deleted when the wireless transmission device is removed from the interface of the personal computer or when the personal computer is turned off.

  By the way, since this type of wireless transmission device is used externally to the interface of a personal computer, the personal computer to which this wireless transmission device is externally attached is not always the same personal computer. A different personal computer may be used each time a device is used. If the same personal computer is externally attached to the wireless transmission device, when the wireless transmission device is externally attached to the interface of the personal computer, the operation setting items of the wireless transmission device are read from the personal computer and the wireless transmission device is connected. Since the data is written in the internal memory of the transmission device, the personal computer can operate the wireless transmission device according to the setting items.

  On the other hand, when the personal computer to which this wireless transmission device is externally attached is different from the personal computer previously attached, the operation setting items of the wireless transmission device are not necessarily installed in advance on the personal computer side. Therefore, unless the operation setting items of the wireless transmission device are installed in advance on the personal computer side, the wireless transmission device cannot be operated according to the setting items.

However, if the operation setting items of the wireless transmission device are not installed in advance on the personal computer side, if the operation setting items of the wireless transmission device are installed on the personal computer, the computer will connect the wireless transmission device in the same way. It is possible to operate according to the setting items, but every time the wireless transmission device is externally installed, installing the wireless transmission device operation setting items on the personal computer requires work time for the installation operation. As a result, work efficiency is reduced accordingly.
