The present invention relates to a Bluetooth data access system, more particularly, to a Bluetooth data access system searching application automatically.
With the development of science and technology, the function of the sensing instrument is also progressing. Conventional sensing instruments, such as weight meters or blood sugar machines, usually have only the sensing function. The user must record the sensed value himself, which is cumbersome and the record is easily lost. Nowadays, a sensing instrument with sensing function is often integrated with the internet of things. The sensed value is smartly recorded in the instrument or uploaded to the cloud. Moreover, the instrument or the cloud correspondingly recommends the user according to the sensed value.
A smart sensing instrument is convenience, but the corresponding application is required to operate or access the instrument. However, each manufacturer or instrument has its own application. That also means if the user has five smart sensing instruments at home, five applications should be installed to operate the instruments. Therefore, it causes the user's inconvenience.
In response to the above-mentioned problems, an object of the present invention is to provide a Bluetooth data access system comprising a Bluetooth device, a Bluetooth gateway, and an application server. The Bluetooth device is for sending a broadcast message. The Bluetooth gateway is coupled to the Bluetooth device to receive the broadcast message, and then the Bluetooth gateway sends a gateway message containing the broadcast message. The application server is connected to the Bluetooth gateway to receive the gateway message, and the application server generates and sends an application message according to the gateway message. Wherein, the Bluetooth gateway receives the application message, generates a control message, and then sends the control message to access or operate the Bluetooth device.
In an embodiment, the broadcast message comprises a device identified code, a universally unique identifier, or a combination thereof. The device identified code is a unique identified code of the Bluetooth device, and the universally unique identifier is an identified code of service contents for the Bluetooth device. The gateway message contains the broadcast message and a gateway identified code. The gateway identified code is a unique identified code of the Bluetooth gateway.
In an embodiment, the application server comprises a data collection module; the data collection module prestores an application able to communicate with Bluetooth device, the device identified code of the Bluetooth device, the universally unique identifier of the Bluetooth device, and the gateway identified code of the Bluetooth gateway. The application server selects the application and generates the application message containing the application according to the gateway message and the related data in the data collection module.
In an embodiment, the Bluetooth gateway comprises a computing unit. After the Bluetooth gateway receives the application message, the computing unit translates the application message to the control message, and then the control message is used to access or operate the Bluetooth device.
In practice, the Bluetooth gateway accesses or operates the Bluetooth device to obtain a service message content, and the Bluetooth gateway sends the service message content to the application server to integrate or analyze the data.
Compare with the prior art, the Bluetooth data access system of the present invention provides the corresponding application to the Bluetooth gateway according to different Bluetooth devices from the application server, so that the Bluetooth gateway can dynamically access or operate various Bluetooth devices without the inherent application, unlike the normal Bluetooth gateway requires the inherent application for various Bluetooth devices to access or operate the Bluetooth devices. Therefore, compared with the normal Bluetooth gateway, the Bluetooth gateway of the present invention can save the storage capacity for various applications. Moreover, the user could operate the different Bluetooth devices conveniently without installing on user's own.
