  • Patent number: 10313866
    Abstract: A method for establishing and monitoring a Bluetooth low energy wireless network comprises the following steps. A first Bluetooth wireless device in the plurality of Bluetooth low energy wireless devices is controlled from a broadcast state into a detection state. In the detection state, the first Bluetooth wireless device receives a first connectable broadcast signal transmitted from a second Bluetooth wireless devices of the Bluetooth low energy wireless device. The first Bluetooth wireless device establishes a first Bluetooth connection with the second Bluetooth wireless device according to the first connection request. A trigger instruction is transmitted from the first Bluetooth wireless device to the second Bluetooth wireless device via the first Bluetooth connection, in order to control the second Bluetooth wireless device to enter into a detection state.

  • Publication number: 20190058739
    Abstract: A Bluetooth data access system comprises a Bluetooth device, a Bluetooth gateway, and an application server. The Bluetooth gateway receives a service code from the Bluetooth device and sends the service code to the application server for getting an application able to communicate with the Bluetooth device. Then, the Bluetooth gateway controls or accesses the Bluetooth device through the application. Compared with the prior art, a Bluetooth gateway of the prior art requires a built-in application of the Bluetooth device to control the Bluetooth device. The present invention utilizes the application server to provide a corresponding application to the Bluetooth gateway based on the different Bluetooth device, so that the gateway can dynamically control or access various Bluetooth devices without the built-in application.
