Wireless device and operating method of wireless communication system
There is provided a wireless device including an earphone set and a charging cradle. The charging cradle is used as means for charging the earphone set. The charging cradle further records connection information of multiple external devices that have been BT connected to the charging cradle. The earphone set receives a connection command from the charging cradle to accordingly form an audio connection to one of the multiple external devices. The charging cradle is further used as a communication medium between the multiple external devices.
1. A wireless device, comprising:
a charging cradle, configured to record connection information of multiple external devices which respectively form a Bluetooth (BT) connection with the charging cradle, and to transmit a connection request command; and
an earphone, configured to be accommodated in the charging cradle for charging, and determine an audio play target according to the connection request command from the charging cradle so as to form an audio connection with one of the multiple external devices, wherein
when the charging cradle is BT connected with a first device and a second device, and the earphone forms a first audio connection with the first device,
the charging cradle is further configured to receive a switch command from the second device to control the earphone to disconnect the first audio connection with the first device and form a second audio connection with the second device.
2. A wireless device, comprising:
a charging cradle, configured to record connection information of multiple external devices which respectively form a Bluetooth (BT) connection with the charging cradle, and to transmit a connection request command; and
an earphone, configured to be accommodated in the charging cradle for charging, and determine an audio play target according to the connection request command from the charging cradle so as to form an audio connection with one of the multiple external devices, wherein
when the charging cradle is BT connected with a first device and a second device,
the charging cradle is further configured to provide current WiFi network information and an IP address of the first device or the second device via the BT connection to cause the first device and the second device to form a WiFi connection.
3. The wireless device as claimed in claim 2 , wherein when one of the first device and the second device is an iPhone, the charging cradle is further configured to receive keep-alive packets from the iPhone to keep the BT connection between the iPhone and the charging cradle alive.
4. The wireless device as claimed in claim 1 , wherein
the charging cradle is further configured to transmit a request signal to the second device to generate the switch command while detecting the BT connection with the first device is interrupted.
5. The wireless device as claimed in claim 1 , wherein
the charging cradle is further configured to transmit a request signal to the second device to generate the switch command while detecting the first audio connection is interrupted.
6. A wireless device, comprising:
a charging cradle, configured to record connection information of multiple external devices which respectively form a Bluetooth (BT) connection with the charging cradle, and to transmit a connection request command; and
an earphone, configured to be accommodated in the charging cradle for charging, and determine an audio play target according to the connection request command from the charging cradle so as to form an audio connection with one of the multiple external devices, wherein
the charging cradle and the earphone form another BT connection therebetween to transmit the connection request command.
7. The wireless device as claimed in claim 2 , wherein
one of the first device and the second device is an iPhone, and the charging cradle is further configured to receive keep-alive packets from the iPhone, and
when the Bluetooth (BT) connection between the iPhone and the charging cradle is interrupted, the WiFi connection between the first device and the second device is interrupted.
8. The wireless device as claimed in claim 2 , wherein the first device is a computer and the second device is a cellphone, and
the first device and the second device are configured to perform at least one of transmitting files, projecting a screen of the cellphone to the computer and controlling the cellphone by the computer via the WiFi connection.
