Description

Low-power bluetooth connection blocking method, device, computer equipment and storage medium

technical field

The present application relates to the technical field of wireless networks, in particular to a method, device, computer equipment, and storage medium for blocking a Bluetooth low-power connection connection.

Background technique

Bluetooth (Bluetooth) is the most widely used short-range wireless communication protocol today. From traditional personal computers, wireless peripherals to smartphones, to various emerging wearable devices, Bluetooth is everywhere. In addition, Bluetooth also plays a role in the development of the Internet of Things (IoT). vital role. Among them, Bluetooth Low Energy (Bluetooth Low Energy, referred to as BLE) is a new technology introduced by the Bluetooth SIG after Bluetooth 4.0. Compared with Bluetooth 3.0 and previous versions, BLE is more focused on maximizing the standby time and connection response speed of the device. , so BLE has been widely used in smart devices that are sensitive to power consumption. In order to be compatible with these smart devices of various shapes, the Bluetooth controllers currently used in personal computers or mobile phones generally support BLE as well as classic Bluetooth.

Compared with traditional Bluetooth technologies such as Basic Rate (BR for short) and Enhanced Data Rate (EDR for short), the Bluetooth SIG introduces a new frequency hopping technology for BLE. In the classic Bluetooth before Bluetooth 4.0, the adaptive frequency hopping technology is more complicated. It needs to measure the signal strength or quality in real time to find out the channel with greater interference, and then the devices at both ends of the Bluetooth connection update the frequency hopping channel sequence according to the measurement results. Ultimately, channels with greater interference are avoided, which leads to the problem of high performance requirements for the Bluetooth system chip (System on Chip, SoC) and high power consumption, which cannot meet the increasing battery life requirements of smart devices. Therefore, after Bluetooth 4.0, the previous adaptive frequency hopping technology was optimized. For example, only 37 optional frequency hopping channels were used, and connection parameters such as hop interval and hopincrement were introduced to control the speed of frequency hopping channel switching and achieve the goal of reducing frequency hopping. The purpose of small power consumption. Although these optimizations have significantly reduced the power consumption of Bluetooth devices, they have also resulted in weaker underlying security of BLE than classic Bluetooth.

However, since the number of frequency hopping channels used is reduced and the switching speed of frequency hopping signals is slowed down, it is easier to monitor BLE connection communication data than classic Bluetooth communication data.

For related technologies, BLE uses frequency hopping technology itself to have the characteristics of anti-interference. How to suppress the signal of BLE connection, that is, block BLE connection, has not yet proposed an effective solution.

In one embodiment, FIG. 2 is a flowchart of a method for blocking a Bluetooth low energy connection according to an embodiment of the present invention. As shown in FIG. 2 , a method for blocking a Bluetooth low energy BLE connection is provided, including the following steps :

Step S210, the Bluetooth low energy system chip monitors each data channel of BLE. According to the maximum number of data channels that BLE SoC can monitor at the same time, select the number of BLE SoC corresponding to the number of data channels, so that BLE SoC can cover all data communication channels of BLE.

In some embodiments, according to the existing BLE communication protocol, the BLE communication network has a total of 40 channels, among which channels numbered 0 to 36 are used for data communication. Each BLE connection will use BLE frequency hopping technology. After the BLE connection is established, the communication terminal will follow the protocol specification and jump to different channels at regular intervals for data transmission. Corresponding to the above 37 data channels, 37 BLE SoCs are used, so that the BLE SoCs correspond to the BLE communication channels one by one, that is, each Bluetooth low energy system chip monitors one channel. In this implementation manner, the channel monitoring is implemented through the BLE SoC having the same number of BLE data channels, which can further improve the accuracy and detection efficiency of the data channel monitoring.

Step S220, determine the channel mapping of the target BLE according to the target access address of the target BLE. According to the terminal that needs to be blocked, obtain the Access Address corresponding to the terminal, which can be determined according to the monitoring results of the BLE SoC. The set of frequency hopping channels used by the BLE connection is called the channel map of the target BLE. Let all BLE SoCs in sniffing mode search for the target Access Address on their respective responsible channels. Once the target Access Address is found on a certain channel, it means that the target BLE connection uses the channel, so the channel is in the channel map. The data channels in the channel map are called active channels.

Step S230, when the first active channel detects the target access address, the Bluetooth low energy system chip corresponding to the first active channel sends blocking data to the first active channel to block the connection of the target BLE. For the monitoring process of the active channel, once the target Access Address is found in the active channel, the BLE SoC in charge of the active channel will send blocking data on the active channel, causing data collisions, resulting in the communication of the target BLE on the active channel cannot proceed normally. Since all active channels are monitored by the BLE SoC, this will cause all data channels used by the target BLE connection to fail to communicate normally, and the target BLE connection will be blocked.

From step S210 to step S230, a low power consumption connection blocking method is provided, and each data channel of BLE is covered and monitored by BLE SoC, and the channel map of the target BLE is determined according to the target Access Address, and the data channel in the channel map When the target Access Address is detected, the blocking data is sent in the data channel to realize the blocking of the BLE connection.

In one embodiment, FIG. 3 is a flowchart of a method for obtaining channel mapping in a Bluetooth low energy connection blocking method according to an embodiment of the present invention. As shown in FIG. 3 , the target is obtained according to the target access address of the target BLE. The process of BLE channel mapping includes the following steps:

Step S310, the Bluetooth low energy system chip searches for the target access address in the corresponding data channel according to the search duration;

In step S320, a channel map is obtained, and the channel map includes the data channel of the searched target access address.

In step S310 to step S320, the search duration is determined according to the BLE data connection interval and the frequency modulation sequence period. For example, according to the existing Bluetooth low-power transmission protocol, the two parties must switch channels every interval specified by connectioninterval, that is, frequency hopping once, where the value range of connectioninterval is between 7.5 milliseconds and 4 seconds, and the step is 1.25 milliseconds. At the same time, according to the BLE frequency hopping channel selection algorithm, it can be known that the frequency hopping sequence period of the BLE connection is 37. Therefore, if the BLE SoC has not received the data packet of the target Access Address after waiting for the time required for a frequency hopping cycle on a data channel, it can be considered that the current channel is not used by the target BLE connection. According to the value range of the connection interval and the period of the BLE frequency hopping sequence, the BLE SoC can calculate that the time required for the BLE connection to complete a frequency hopping sequence period is between 277.5 (7.5×37) milliseconds and 148 (4×37) seconds . If within 148 seconds, the data packet containing the target Access Address still does not appear in the channel, then the channel is not used by the target BLE connection, so it is not in the channel map. This embodiment provides a method of determining the search duration according to the BLE connection interval and the frequency modulation sequence cycle, and searching for the access address of the target BLE on each data channel according to the search duration to determine the channel map, which improves the channel map. The inference time is also improved, and the accuracy of the channel map is also improved, so that the BLE connection can be blocked more efficiently and accurately.

In one embodiment, FIG. 4 is a flowchart of a method for updating channel mapping in a Bluetooth low energy connection blocking method according to an embodiment of the present invention. As shown in FIG. 4, the target BLE address is obtained according to the target access address of the target BLE. After channel mapping, the method includes the following steps:

Step S410, in the case that the target access address is detected in the inactive channel, it is indicated that the channel mapping needs to be updated. After the Channel map is inferred, the monitored BLE SoC will be divided into two groups: one group is responsible for monitoring the data of the active channel; the other group is responsible for monitoring the data of the inactive channel, and the inactive channel refers to the data not in the channel map channel. For the data of the inactive channel, once the nRF51822 of the inactive channel group finds that the target Access Address appears in it, it means that the target BLE connection has updated the channel map, and the updated channel map needs to be obtained again.

In step S420, an updated channel mapping is obtained according to the target access address. Re-infer the updated channel map based on the target AccesAddress.

From step S410 to step S420, by monitoring the inactive channel, the change of the channel map of the target BLE can be obtained in time, which solves the problem that the target BLE detects interference, and then updates the used frequency hopping channel sequence to avoid interference, resulting in channel map Update, blocking issues that don't work correctly.

In one embodiment, FIG. 5 is a flow chart of a method for sending blocking data in a low-power Bluetooth connection blocking method according to an embodiment of the present invention. As shown in FIG. 5, the target access address is detected in the first active channel In the case of , sending the blocking data to the first active channel by the Bluetooth low energy system chip corresponding to the first active channel includes:

Step S510, when the target access address is detected by the first active channel, the Bluetooth low energy system chip corresponding to the first active channel sends blocking data to the first active channel;

Step S520, after the preset sending duration, the Bluetooth low energy system chip corresponding to the first active channel stops sending the blocking data.

From step S510 to step S520, for the data of the active channel, once the BLESoC responsible for monitoring the active channel group finds the target Access Address in the active channel it is responsible for monitoring, the BLE SoC will send a pre-request message to the target Access Address on the active channel Set the duration of blocking data, and re-enter the monitoring mode after sending. Wherein, the sending duration of the blocking data is determined according to the connection interval of the BLE. In some embodiments, the above sending duration is set by acquiring the value of the connection interval of the target BLE. Since the target BLE must hop every other connection interval, that is, replace the currently used data channel. At this time, it is also found that the time point of AccessAddress is start, then it can be calculated that subsequent normal BLE data packets of the current channel may arrive within the time period of start+connection interval seconds. Since the second blocking data sent by BLE SoC during this period occupies the channel currently used by the target BLE connection, if the target BLE connection sends data on this channel again, data collision will occur, resulting in communication failure. Moreover, since the sending of the blocking information lasts only for the target BLE to occupy the time of the data channel, the blocking data will not affect other BLE connections. The method provided in this embodiment blocks a specific one of the connections without interfering with the normal communication of other BLE connections, so that the blocking of the BLE connection is highly targeted and more precise.

In one embodiment, after the preset sending duration, the Bluetooth low energy system chip corresponding to the first active channel stops sending the blocking data comprising: after 4 seconds, the low power consumption corresponding to the first active channel The bluetooth system chip stops sending blocking data, and continues to monitor the first active channel. Since the existing Bluetooth protocol stipulates that the BLE connection is every 7.5 milliseconds to 4.0 seconds, then the maximum time that the BLE connection stays on the current channel is 4 seconds, and the duration of sending the blocked data is uniformly set to 4 seconds, 4 seconds Afterwards, the BLE SoC returns to the monitoring mode again, without the need to obtain different connection intervals according to different target BLEs each time, which can simplify the BLE connection blocking solution and make the blocking more efficient.

The embodiments of the present application are described and illustrated through preferred embodiments below.

FIG. 6 is a schematic diagram of a method for blocking a Bluetooth low energy connection according to a preferred embodiment of the present invention. According to the existing BLE protocol, BLE uses 37 data channels. In order to cover 37 data channels at the same time, 37 nRF51822 chips of Nordic Company are used, and their numbers are 0 to 36, corresponding to the data channels of BLE one by one.

When 37 pieces of nRF51822 are powered on and initialized, they will enter the sniffing mode and begin to identify the BLE connections that exist around them. These BLE connections may be more than one, and the present invention will block a specific one of them without interfering with the normal communication of other BLE connections, so as to realize directional blocking.

The premise of realizing directional blocking is to identify the target BLE connection. This invention will use all 37 pieces of nRF51822 to complete the connection identification. Because the established BLE connection will perform frequency hopping communication on 37 data channels, using 37 pieces of nRF51822 can cover all 37 data channels, so that the Access Address connection identifiers of all surrounding BLE connections can be sniffed.

After the BLE connection is identified, the present invention infers the frequency-hopping channel mapping used by the target BLE connection, that is, channelmap, and the set of frequency-hopping channels used by the target BLE connection is called a channel map. Let 37 pieces of nRF51822 in sniffing mode search for the target Access Address on their respective channels for 148 seconds. Once an AccessAddress is found on a channel, it means that the channel is used by the target BLE connection. So the channel is also in the channel map. If within 148 seconds, the data packet containing the target Access Address still does not appear in the channel, then the channel is not used by the target BLE connection, so it is not in the channel map.

After the Channel map is inferred, 37 nRF51822 blocks will be divided into two groups. One group is responsible for sniffing data of inactive channels not in the channel map; the other group is responsible for sniffing data of active channels included in the channel map.

For the data of the inactive channel, once the nRF51822 of the inactive channel group finds that the target Access Address appears in it, it means that the target BLE connection has updated the channel map. At this time, return to the step of inferring the channel map based on the Access Address, and re-infer the updated channel map.

For the data of the active channel, once the nRF51822 of the active channel group finds the target Access Address, it immediately changes from the sniffing mode to the sending mode, and continuously sends 4 seconds of blocking data to the target Access Address on the channel it is responsible for. After 4 seconds, nRF51822 returns to sniffing mode. So repeat.

The Bluetooth protocol stipulates that the BLE connection is every 7.5 milliseconds to 4.0 seconds, with a step of 1.25 milliseconds, and the frequency must be jumped once, that is, the currently used data channel is replaced. Then the maximum time that the BLE connection stays on the current channel is 4 seconds. At this time, it is also found that the time point of the Access Address is start, then it can be calculated that the subsequent normal BLE data packets of the current channel may arrive within the time period of start+4 seconds. Since the second blocking data sent by nRF51822 during these 4 seconds occupies the channel currently used by the target BLE connection, if the target BLE connection sends data on this channel again, data collision will occur, resulting in communication failure. Since all channels in the channel map are sniffed by nRF51822, this will cause all data channels used by the target BLE connection to be unable to communicate, and the BLE connection will be blocked.

The Bluetooth low energy connection blocking method in the above preferred embodiment is a full-channel directional blocking method. Full channel here refers to the 37 data channels used by BLE. Directional blocking means that the blocking method proposed in the present invention only blocks the specified BLE connection, and will not affect other BLE connections, and will not affect other non-channels under the same frequency band 2.4GHz. BLE communication protocol. And after covering and monitoring all BLE data channels, it is only necessary to deduce the channel map to achieve the purpose of blocking the BLE connection in the future, and the connection parameter update sent by the BLE connection will not be missed.
