The method provided by the first embodiment of the present application may be executed in a mobile terminal, a computer terminal, or a similar computing device. Taking the example of the present invention running on a mobile terminal, fig. 1 is a block diagram of a hardware structure of the mobile terminal of a data connection processing method according to an embodiment of the present invention. As shown in fig. 1, the mobile terminal may include one or more (only one shown) processors 102 (the processors 102 may include, but are not limited to, a processing device such as a microprocessor MCU or a programmable logic device FPGA, etc.), a memory 104 for storing data, and a transmission device 106 for communication functions. It will be understood by those skilled in the art that the structure shown in fig. 1 is only an illustration and is not intended to limit the structure of the electronic device. For example, the mobile terminal may also include more or fewer components than shown in FIG. 1, or have a different configuration than shown in FIG. 1.

The memory 104 may be used to store computer programs, for example, software programs and modules of application software, such as computer programs corresponding to the data connection processing method in the embodiment of the present invention, and the processor 102 executes various functional applications and data processing by running the computer programs stored in the memory 104, so as to implement the above-mentioned method. The memory 104 may include high speed random access memory, and may also include non-volatile memory, such as one or more magnetic storage devices, flash memory, or other non-volatile solid-state memory. In some examples, the memory 104 may further include memory located remotely from the processor 102, which may be connected to the mobile terminal over a network. Examples of such networks include, but are not limited to, the internet, intranets, local area networks, mobile communication networks, and combinations thereof.

In one example, the transmission device 106 may be a Radio Frequency (RF) module, which is used for communicating with the internet in a wireless manner.

For a mobile terminal as shown in fig. 1, the method comprises: BLE slave device and BLE master device. The broadcast data of the BLE slave device (BLE intelligent household electrical appliance device) carries user-defined data and an RSSI value (signal strength). The BLE master device (such as a mobile phone terminal) searches for the connectable BLE slave device, when receiving the broadcast packet of the device, a connection request can be sent out, and after the connection is established, the connection can be controlled through the BLE.

BLE device discovery logic is as follows:

step one, BLE slave equipment actively broadcasts ADV _ IND;

step two, the BLE master equipment starts to receive a BLE broadcast packet;

step three, the BLE master equipment judges whether the received ADV _ IND data conforms to the protocol agreement of the BLE master equipment, if so, the BLE master equipment represents the equipment which needs to be connected; if not, it is discarded.

And step four, if the equipment is judged to be the equipment, sending the SCAN _ REQ, and the operation can save the sending of BLE data stream of the mobile phone end and save more electricity.

And step five, after receiving the request, the BLE device sends the SCAN _ RSP, which includes more user-defined data.

In this embodiment, a method for processing a data connection operating in the mobile terminal is provided, and fig. 2 is a flowchart of a method for processing a data connection according to an embodiment of the present invention, as shown in fig. 2, the flowchart includes the following steps:

step S202, a first broadcast packet is received.

The foregoing steps are performed in a first device, where the first device receives a first data packet, where the first data packet refers to a broadcast data packet carrying an RSSI value and sent by a second device, the first device is a BLE master device used for discovering a connectable device, and the second device is a BLE slave device used for connecting with the BLE master device;

it should be noted that there is an RSSI value in each broadcast packet received at the first device. The value range of the RSSI value is 0 to-127, and if the RSSI value is < -80, the signal is considered to represent a weak signal.

It should be noted that, before receiving the first data packet, the first device may determine whether the received data conforms to its protocol convention. If the device is matched, the device is the own device needing connection. In the broadcast data of the second device (such as a BLE intelligent household appliance device), the user-defined data and the RSSI (i.e. representing the signal strength) are carried, the first device (such as a mobile phone) searches for the connectable second device, and can send out a connection request when receiving a broadcast packet of the device, and can control through the BLE after the connection is established.

Step S204, determining connectable equipment according to the RSSI value in the first broadcast data packet;

in the case where the RSSI value in the first broadcast packet satisfies a threshold, the signal strength is considered to satisfy the condition of the connectable device. And the connectable devices may be displayed in a device list according to different RSSI values. It is noted that the connectable or deletable BLE slave devices may be visually displayed in the device list at the user interface. Including one or more BLE slave devices in the second device to which connectivity may be made.

A step S206 of receiving a second broadcast packet in a case where a connection is established with the connectable device;

that is, on the premise that the connection between the first device and the second device is already connected, the first device continues to receive the second packet, where the second packet includes a plurality of consecutive broadcast packets.

And step S208, determining non-connectable devices among the connectable devices according to the RSSI value in the second broadcast packet.

Non-connectable devices are determined among the connectable devices according to the strength of the RSSI values, and the non-connectable devices may be displayed in a device list according to different RSSI values. It is noted that the second disconnectable device may be visually displayed in the device list at the user interface, so that the user may directly view through the user interface. Including one or more BLE slave devices in the second device that may be disconnected.

Step S210, through the non-connectable devices, determining a device that can remain connected among the connectable devices.

Through the above steps, since connectable devices are determined according to the RSSI value in the first broadcast packet, and non-connectable devices among the connectable devices are determined according to the RSSI value in the received second broadcast packet in case the connectable devices establish a connection. Therefore, the problem that the power of the connection between the first device and the discoverable second device is not high can be solved, and the effect of updating the discoverable second device which can be stably connected as soon as possible by judging the strength change of the RSSI value in the broadcast data packet in the device while improving the success rate of the device connection when the second device is discovered is achieved.

Preferably, the method further comprises: a device that can maintain connection is determined among the connectable devices through the non-connectable devices, as shown in fig. 3, and the connection with the non-connectable device is disconnected at step S212. I.e. if a non-connectable device is determined, the connection to said non-connectable device is disconnected.

Due to the instability of the BLE broadcasting protocol, the availability of the equipment cannot be guaranteed after one broadcast is received, the success rate of equipment connection in equipment discovery can be improved by judging the RSSI value in the broadcast data packet, meanwhile, due to the characteristics of the BLE broadcasting protocol, the first equipment cannot know that the BLE equipment stops broadcasting, and the fact that the BLE equipment stops broadcasting can be judged as accurately as possible by judging the RSSI value in the broadcast data packet again.

In an embodiment of the present application, the determining connectable devices according to the RSSI value in the first broadcast packet includes: determining the connectable device in case the RSSI values in three consecutive packets of data in the first broadcast packet are all greater than a first threshold value. That is, if the RSSI values of three consecutive packets are all greater than-80, it indicates that it is a stably connectable device.

In an embodiment of the present application, said determining connectable devices according to RSSI values in said first broadcast packet previously comprises: discarding the three consecutive packets of data in the first broadcast packet if the RSSI value of any one of the three consecutive packets of data in the first broadcast packet is less than a first threshold value; discarding a first one of two consecutive packets of data in the first broadcast packet if the RSSI values of the two consecutive packets of data are both less than a first threshold value.

If any one of three consecutive packets in the first broadcast packet has RSSI < -80 before the connectable device is determined, the RSSI value comparison process is not performed for discarding. Meanwhile, if two consecutive packets RSSI < -80 in the first broadcast packet, the first packet data is also discarded and recalculated from the next packet.

In an embodiment of the present application, the determining, among the connectable devices, a non-connectable device according to the RSSI value in the second broadcast packet includes: determining a non-connectable device among the connectable devices in case the RSSI values in a plurality of consecutive data packets in the second broadcast data packet are all smaller than a second threshold value. Specifically, for the second broadcast packet, if the RSSI values in five consecutive broadcast packets are all less than-100, it is determined that a non-connectable device, i.e., a device, among the connectable devices can be deleted.

In an embodiment of the present application, the determining, among the connectable devices, a non-connectable device according to the RSSI value in the second broadcast packet includes: determining the number of devices in the connectable devices in case the RSSI values in a consecutive plurality of the second broadcast packets are each less than a second threshold; in the case where the number of devices among the connectable devices is greater than two, a non-connectable device is determined among the connectable devices. Specifically, in the case where the RSSI values of the second broadcast packet in three consecutive broadcast packets are all less than-100, it is necessary to determine the number of currently connectable devices, and in the case where the number of connectable devices is greater than two, it is determined that a non-connectable device, that is, a device indicating that the device can be deleted, is possible. For example, the device list searched in the first 5s and the device list searched in the last 5s may be compared, if there are more than 2 different devices, it indicates that the current bluetooth environment has changed, and the mobile phone may have moved the location, and at this time, it is considered that the distance between the mobile phone and the BLE device that can be stably connected is exceeded, it indicates that the devices may be deleted.

In an embodiment of the present application, the determining a non-connectable device among the connectable devices according to the RSSI value in the second broadcast packet includes: disconnecting the non-connectable device in case that a broadcast packet is not received within a preset time period; and disconnecting the non-connectable device when the RSSI value of the Nth packet in the plurality of consecutive packets in the second broadcast packet is less than the RSSI value of the N-1 th packet, the RSSI value of the N-1 th packet is less than the RSSI value of the N-2 th packet, and the RSSI value of the N-3 th packet is less than a second threshold value. Specifically, if a plurality of packets in the second broadcast packet are smaller and the minimum RSSI value is smaller than the second threshold value, it is determined that a non-connectable device among the connectable devices, i.e., a device may be deleted. For example, if the RSSI value in four consecutive broadcast packets is smaller and the RSSI value in the last broadcast packet is less than-100, it indicates that two devices are farther and farther away and beyond the distance that can be stably connected, and indicates that the devices can be disconnected after being deleted.

Through the above description of the embodiments, those skilled in the art can clearly understand that the method according to the above embodiments can be implemented by software plus a necessary general hardware platform, and certainly can also be implemented by hardware, but the former is a better implementation mode in many cases. Based on such understanding, the technical solutions of the present invention may be embodied in the form of a software product, which is stored in a storage medium (e.g., ROM/RAM, magnetic disk, optical disk) and includes instructions for enabling a terminal device (e.g., a mobile phone, a computer, a server, or a network device) to execute the method according to the embodiments of the present invention.

As used below, the term "module" may be a combination of software and/or hardware that implements a predetermined function. Although the means described in the embodiments below are preferably implemented in software, an implementation in hardware, or a combination of software and hardware is also possible and contemplated.

Including one or more BLE slave devices in the second device that may be disconnected.

Through the module, since the connectable device is determined according to the RSSI value in the first broadcast packet, and the non-connectable device in the connectable device is determined according to the RSSI value in the received second broadcast packet when the connectable device establishes the connection, the problem that the power of the connection between the first device and the discoverable second device is not high can be solved, and the effect of updating the discoverable second device stably by judging the strength change of the RSSI value in the broadcast packet in the device while improving the success rate of the device connection when the second device discovers is achieved.

In order to better understand the processing flow of the data connection, the following explains the technical solutions with reference to the preferred embodiments, but the technical solutions of the embodiments of the present invention are not limited.

The preferred embodiment of the present invention can improve the success rate of device connection in the device list when the device is found by judging the signal strength in a plurality of continuous broadcast data packets. And at the same time it can be determined as much as possible whether the device has stopped broadcasting. Therefore, the user is updated and prompted, and better user experience is achieved.

Fig. 5 is a flowchart illustrating a processing method of data connection according to a preferred embodiment of the present invention, as shown in fig. 5, including the following steps:

in step S502, a BLE device is discovered.

The discovery of BLE devices (that is, BLE devices in this application all refer to BLE slave devices, and a mobile phone terminal represents a BLE master device) mainly includes the following interaction processes: the BLE equipment actively broadcasts ADV _ IND, the mobile phone end starts to receive BLE broadcast packets, the mobile phone judges whether the received ADV _ IND data conforms to the protocol convention of the mobile phone or not, and if yes, the mobile phone indicates the equipment needing to be connected; if not, it is discarded. And if the device is judged to be the own device, the SCAN _ REQ is sent, so that the sending of BLE data streams at the mobile phone end can be saved, and more electricity can be saved. Upon receiving the request, the BLE device sends SCAN _ RSP, which includes more user-defined data.

Each packet of data received by the mobile phone end has an RSSI value, the RSSI value range is 0 to-127, if the RSSI < -80, a weak signal is represented, so the operation steps of step S506, step S508 and step S510 need to be performed.

In step S504, if the RSSI of three consecutive packets is greater than-80, it indicates that it is a device that can be stably connected.

In step S506, if any packet RSSI < -80 of the three continuous packets, the packet RSSI < -80 is discarded.

In step S508, if two consecutive packets of RSSI < -80, the first packet of data is also discarded and recalculated.

Since the BLE device may stop broadcasting data in the broadcasting process due to connection by other devices, broadcast stop of the BLE device itself, or power failure, and the BLE device is not known as a mobile phone terminal at this time, it is necessary to find that the device stops broadcasting in time, and it is necessary to continue to step S512.

Step S510, if any broadcast packet of the device is not received within 15S, it indicates that the device can delete the broadcast packet.

In step S512, if the RSSI in five consecutive broadcast packets is less than-100, it indicates that the device can be deleted.

After the RSSI in the three continuous broadcast packets is less than-100, the equipment list searched in the first 5s and the equipment list searched in the last 5s are judged to be compared; if there are more than 2 different devices, it indicates that the current bluetooth environment has changed, and the mobile phone end may have moved the position, and at this time, it is considered that the distance between the mobile phone end and the BLE device which can be stably connected has exceeded, and the device is deleted.

Step S514, if the RSSI value in the four consecutive broadcast packets is smaller and smaller, and the RSSI value in the last broadcast packet is smaller than-100, it indicates that the two devices are farther and farther away and exceed the distance that can be stably connected, and the devices are deleted.
