摘要： A wireless system includes a control device and a wireless communication device. The control device switches between a control-side access point mode and a control-side station mode. In the control-side access point mode, the control device receives a connection request from the wireless communication device to establish a connection and, in the control-side station mode sends a connection request to the wireless communication device to establish a connection. The control device sends a sleep command or a wake-up command to the wireless communication device with which the connection is established.
