Detailed Description
In the prior art, each B L E equipment manufacturer has self-defined B L E services, but the self-defined services cannot be directly displayed on a setting-Bluetooth interface of a mobile phone, an iPad or a computer, when a user needs to connect the mobile phone, the iPad or the computer with the B L E equipment, an APP must be installed on the mobile phone, the iPad or the computer and opened to search, and then the B L E equipment is connected, HOGP is a protocol specified by a Bluetooth official party, the B L E equipment with the protocol can be displayed on the setting-Bluetooth interface of the mobile phone, the iPad or the computer, and the APP does not need to be downloaded by the mobile phone, the iPad or the computer.
In order to make the aforementioned features and advantages of the present invention comprehensible, embodiments accompanied with figures are described in detail below. The detailed description is merely intended to facilitate an understanding of the invention, and the scope of the invention is not limited to the specific description in the specific embodiments.
Fig. 1 shows an embodiment of a method for automatically connecting and controlling a bluetooth low energy device according to the present invention, in which the method comprises the following steps:
step S101: a hop protocol step is added.
In one embodiment of the invention, the HOGP protocol is added to the B L E device.
The Bluetooth low power consumption (B L E) technology is a low-cost, short-distance, interoperable and robust wireless technology, and works in an unlicensed 2.4GHz ISM radio frequency band, which utilizes an intelligent means to reduce power consumption to the maximum extent.A B L E technology adopts a variable connection time interval, which can be set to be from several milliseconds to several seconds according to specific applications, and meanwhile, a B L E technology adopts a quick connection mode, so that the technology is in a 'non-connection' state in idle, and at the moment, two ends of a link only know each other, a link is opened only when working is necessary, and then the link is closed in the shortest possible time.
In one embodiment of the present invention, the B L E device may be a bluetooth headset, a bluetooth mouse, a bluetooth speaker, a bluetooth MP3, a bluetooth flash drive, a bluetooth adapter, a bluetooth CF card, a bluetooth bracelet, a sports watch, a weight scale, a pedometer, a smart bracelet, a sphygmomanometer, a printer, a bluetooth work card, or the like.
The Bluetooth center device can display B L E devices supporting a Bluetooth technology alliance SIG organization standard protocol in a setup-Bluetooth interface, and the HOGP protocol is one of the standard protocols, so that automatic connection of the Bluetooth center device and the B L E devices is achieved.
Step S102: and (5) automatically connecting.
In the specific embodiment, B L E equipment added with HOGP protocol broadcasts first, namely B L E equipment added with HOGP protocol continuously sends broadcast signals, the broadcast interval is t, each time a broadcast packet is sent, the broadcast packet can be called a broadcast event, B L E equipment added with HOGP protocol continuously sends the broadcast signals to Bluetooth center equipment, at the moment, the Bluetooth center equipment opens Bluetooth in a system-Bluetooth interface, namely opens a radio frequency receiving window and waits for a system search result, if the radio frequency receiving window of the Bluetooth center equipment is successfully matched with a transmitting window sent by broadcasting, the Bluetooth center equipment receives the broadcast signals, and at the moment, B L E equipment added with HOGP protocol appears in a list of the search result.
Since the pairing or binding success is a probabilistic event, the bluetooth center device scanning the B L E device added with the hopp protocol is also a probabilistic event, that is, the bluetooth center device may only need one broadcast event to scan the B L E device added with the hopp protocol, or the bluetooth center device may need several broadcast events or even more to scan the B L E device added with the hopp protocol.
The two devices are paired or bound within a certain time, at the moment, the Bluetooth center device sends a connection request, namely, the B L E device added with the HOGP protocol is clicked in a system-Bluetooth interface, and the Bluetooth center device receives a data packet sent by the B L E device added with the HOGP protocol, which indicates that the two devices are successfully connected.
Step S103: and (5) controlling.
The RSSI is too low, indicating that the signal received by the B L E device is too weak and that the two bluetooth devices may be disconnected at any time.
In the prior art, when a bluetooth center device scans a B L E device added with a hopp protocol, a bottom protocol stack will report an event to an upper layer, and parameters carried by the bottom protocol stack include an RSSI, because the RSSI changes during each connection event, after the two devices are connected, a data link layer LL C of the bluetooth center device sends an RSSI query request, LL C starts a received power integrating circuit (physical layer), and when the circuit finishes working and prepares data, a completion event is sent to the upper layer, and the RSSI can be obtained through the carried parameters.
In the prior art, the estimated distance between two bluetooth devices can be obtained by the following formula: d = 10^ (abs (RSSI) -A)/(10 × n)), wherein: d represents the calculated distance, RSSI represents the received signal strength (negative), a represents the signal strength at 1 meter separation between the transmitting and receiving ends, and n represents the ambient attenuation factor. The A value and the n value can be obtained only by field testing continuously, the environmental attenuation factors of different fields are different, and even the environmental attenuation factors are influenced to a great extent by the obstruction of objects in the same field. However, the default values of the parameters A and n are set at the same site, so that the relative distance between two Bluetooth devices can be roughly calculated.
In the specific embodiment, after the connection is successful, the B L E device with the HOGP protocol detects the bluetooth signal intensity of the bluetooth center device in real time, if the bluetooth signal intensity is greater than or equal to a preset threshold, that is, the distance between the B L E device with the HOGP protocol and the bluetooth center device is less than a preset distance, the B L E device with the HOGP protocol is turned on through parallel input and output PIO level hopping, and if the bluetooth signal intensity is less than the preset threshold, that is, the distance between the B L E device with the HOGP protocol and the bluetooth center device is greater than the preset distance, the B L E device with the HOGP protocol is turned off through parallel input and output PIO level hopping.
By utilizing the step, the automatic switch of the B L E equipment can be controlled by judging the distance between the Bluetooth center equipment and the B L E equipment with the HOGP protocol, the condition that a user forgets to close the B L E equipment is avoided, resources are saved, and meanwhile, the user can timely master the running condition of the B L E equipment.
As shown in FIG. 2, in the prior art, B L E equipment can automatically initiate broadcasting, but the broadcasting cannot be displayed on a Bluetooth interface of a mobile phone, an iPad or a computer, and APP installation and searching are required for the mobile phone, the iPad or the computer.
