The first embodiment of the application provides a classical bluetooth link construction method which is applied to a second bluetooth device which establishes a BLE link with a first bluetooth device. The step of constructing a classical bluetooth link for the second bluetooth device is shown in fig. 1, and includes:
step S101: a target data packet sent by a first bluetooth device is received via a BLE link.
In this step, the target packet includes a first transceiver window opening time, first clock information of the first bluetooth device, a classical bluetooth address of the first bluetooth device, and a logical address of classical bluetooth allocated to the second bluetooth device.
The first receiving and transmitting window opening time is determined by the first Bluetooth device based on the local clock signal of the first Bluetooth device, namely, when the local clock signal of the first Bluetooth device reaches the first receiving and transmitting window opening time in the first Bluetooth device, the first Bluetooth device can open the receiving and transmitting window.
For the first clock information of the first bluetooth device, when the first bluetooth device is a BLE link master device and the second bluetooth device is a BLE link slave device, the first clock information may be a time point of a local clock of the first bluetooth device when the target data packet is transmitted. For example, when the first bluetooth device sends the target data packet when the local clock time point is 2, the first clock signal in the target data packet is time point 2. When the first bluetooth device is a BLE link slave device and the second bluetooth device is a BLE link master device, the first clock information may be a clock difference between the first bluetooth device and the second bluetooth device. That is, the first bluetooth device has previously determined a clock difference between the first bluetooth device and the second bluetooth device, and then transmits the determined time difference as first clock information to the second bluetooth device.
Step S102: a clock difference between the first bluetooth device and the second bluetooth device is determined based on the first clock information.
In this step, as specifically described in the foregoing step S101, when the first bluetooth device is a BLE link master device and the second bluetooth device is a BLE link slave device, the first clock information may be a time point of a local clock of the first bluetooth device when the target data packet is transmitted. As shown in fig. 2, determining the clock difference between the first bluetooth device and the second bluetooth device according to the first clock information at this time may specifically include the following steps:
step S201: and acquiring second clock information of the second Bluetooth device when the target data packet is received.
In this step, when the second bluetooth device receives the target data packet, the second bluetooth device may record a time point of the local clock of the second bluetooth device at this time as the second clock signal. For example, when the second bluetooth device receives the target data packet, the local clock of the second bluetooth device may have a time point of 5, and the time point of 5 may be used as the second clock signal.
Step S202: and determining the clock difference according to the difference value between the second Bluetooth information and the first Bluetooth information.
In some embodiments of the present application, a difference between a time point of a local clock of the second bluetooth device corresponding to the second bluetooth information and a time point of a local clock of the first bluetooth device corresponding to the first bluetooth device may be directly used as a clock difference between the first bluetooth device and the second bluetooth device. Therefore, the clock difference acquisition difficulty between the first Bluetooth device and the second Bluetooth device can be effectively reduced, and the requirement on hardware devices is reduced.
Alternatively, in some other embodiments of the present application, a counter may be included in the second bluetooth device, where the counter continues to count in the second bluetooth device, starting from 0 when equal to the maximum value. The target data packet may further include a synchronization word, where the synchronization word is coding information pre-agreed by the first bluetooth device and the second bluetooth device, the first bluetooth device writes the synchronization word into a header of the target data packet when sending the target data packet, the second bluetooth device obtains a count value of the counter when receiving the synchronization word, and determines a clock phase difference between the second bluetooth device and the first bluetooth device according to the count value, where the clock phase difference is a phase difference existing between local clocks of the first bluetooth device and the second bluetooth device. Specifically, the error between the local clocks of the first bluetooth device and the second bluetooth device is not necessarily a complete period, for example, at the same time, the local clock in the first bluetooth device corresponds to a time point of 3, and at this time, the local clock in the second bluetooth device may correspond to a time point of 5.3. The difference between 5 and 3 is the time period difference between the first bluetooth device and the second bluetooth device, and 0.3 is the clock phase difference between the first bluetooth device and the second bluetooth device. After the clock phase difference between the first Bluetooth device and the second Bluetooth device is determined, taking the sum of the clock phase difference and the difference between the second Bluetooth information and the first Bluetooth information as the clock difference. Thus, the clock phase difference of the second Bluetooth device and the first Bluetooth device is determined by acquiring the count value of the counter.
Further, in various embodiments of the present application, the number of counters in the second bluetooth device may be plural. For example, in some embodiments of the present application, the second bluetooth device may include two counters, where the count time difference between the two counters may be different, for example, one large time difference counter with a count time difference of 312.5 or 625us may be included, counting at intervals of 312.5 or 625us, and the other count time difference may be a fine counter with a count time difference of less than 1us, such as 0.5us, 0.7us, etc. The fine counter can count in the counting interval of the large time difference counter, namely, each time the large time difference counter counts, the fine counter counts from zero until the large time difference counter counts next time, and the fine counter counts and clears again from zero. In this case, the count values of the acquisition counters may be the count values of the respective acquisition counters.
Step S103: and determining the second receiving and transmitting window opening time and the frequency hopping frequency point according to the clock difference, the first receiving and transmitting window opening time, the classical Bluetooth address and the logic address.
In this step, the sum of the clock difference and the first transceiver window opening time may be used as the second transceiver window opening time. For example, if the time period difference in the clock difference is 3 and the time phase difference is 0.4, the clock difference is 3.4 and the first transceiver window opening time is 7, and the sum of the clock difference 3.4 and the first transceiver window opening time 7 is 10.4 at this time may be regarded as the second transceiver window opening time.
The frequency hopping point can be obtained through a frequency hopping algorithm according to a classical Bluetooth address of the first Bluetooth device, a logic address of classical Bluetooth distributed to the second Bluetooth device and first clock information of the first Bluetooth device, and the second Bluetooth device knows clock differences of the second Bluetooth device and the first Bluetooth device and the classical Bluetooth address of the second Bluetooth device, so that the second Bluetooth device can calculate the current clock of the first Bluetooth device at each moment, and further calculate the frequency hopping point.
Step S104: and opening the receiving and transmitting window when the self clock reaches the opening time of the second receiving and transmitting window.
In this step, after determining the second transceiver window opening time, the second bluetooth device opens the transceiver window when its own local clock reaches the second transceiver window opening time. Because the second receiving and transmitting window opening time is determined according to the clock difference and the first receiving and transmitting window opening time, when the local clock of the second Bluetooth device reaches the second receiving and transmitting window opening time, the local clock of the first Bluetooth device reaches the first receiving and transmitting window opening time, and at the moment, the receiving and transmitting windows of the first Bluetooth device are also opened simultaneously.
Step S105: and establishing a classical Bluetooth link with the first Bluetooth device through the receiving and transmitting window according to the frequency hopping frequency point.
In this step, the transceiver windows of the first bluetooth device and the second bluetooth device are opened simultaneously, so that the construction data of the classical bluetooth link can be exchanged through the transceiver windows according to the frequency hopping frequency points at this time, and the classical bluetooth link between the first bluetooth device and the second bluetooth device can be established according to the construction data.
Compared with the prior art, in the classical bluetooth link construction method provided by the first embodiment of the present application, under the condition that the first bluetooth device and the second bluetooth device have established a BLE link, the second bluetooth device directly receives a target data packet sent by the first bluetooth device through the BLE link, according to first clock information contained in the target data packet, and in combination with local clock information in the second bluetooth device, a clock difference between the first bluetooth device and the second bluetooth device can be determined, according to the clock difference and a first transceiver window opening time based on a clock of the first bluetooth device, the second bluetooth device can determine a second transceiver window opening time based on a clock of the second bluetooth device, when the clock of the second bluetooth device reaches a second transceiver window opening time, the second bluetooth device opens a transceiver window, and can exchange classical bluetooth link data packets with the first bluetooth device through the transceiver window, thereby establishing a classical bluetooth link, and the first bluetooth device and the second bluetooth device simultaneously open the transceiver window at the same time, thereby reducing delay in the classical bluetooth link construction process; in addition, the Page and Page Scan processes in the traditional technology are omitted, and the energy consumption can be effectively reduced.
The second embodiment of the application provides a classical bluetooth link construction method, which is applied to a first bluetooth device which has established a BLE link with a second bluetooth device. The step of constructing a classical bluetooth link for the first bluetooth device is shown in fig. 3, and includes:
step S301: the target data packet is sent to the second bluetooth device via the BLE link.
In this step, the target data packet includes a first transceiver window opening time, first clock information when the first bluetooth device transmits the target data packet, a classical bluetooth address of the first bluetooth device, and a logical address allocated to the second bluetooth device. The first receiving and transmitting window opening time is determined by the first Bluetooth device based on the local clock signal of the first Bluetooth device, namely, when the local clock signal of the first Bluetooth device reaches the first receiving and transmitting window opening time in the first Bluetooth device, the first Bluetooth device can open the receiving and transmitting window.
For the first clock information of the first bluetooth device, when the first bluetooth device is a BLE link master device and the second bluetooth device is a BLE link slave device, the first clock information may be a time point of a local clock of the first bluetooth device when the target data packet is transmitted. For example, when the first bluetooth device sends the target data packet when the local clock time point is 2, the first clock signal in the target data packet is time point 2. When the first bluetooth device is a BLE link slave device and the second bluetooth device is a BLE link master device, the first clock information may be a clock difference between the first bluetooth device and the second bluetooth device. That is, the first bluetooth device has previously determined a clock difference between the first bluetooth device and the second bluetooth device, and then transmits the determined time difference as first clock information to the second bluetooth device.
Specifically, the step of the first bluetooth device predetermining the clock difference between the first bluetooth device and the second bluetooth device may be receiving, via the BLE link, a sample data packet sent by the second bluetooth device, where the sample data packet includes second clock information of the second bluetooth device, and the second clock information may be a clock signal of a local clock of the second bluetooth device when the second bluetooth device sends the sample data packet, and determining the clock difference between the first bluetooth device and the second bluetooth device according to the second clock information.
Specifically, the clock difference between the first bluetooth device and the second bluetooth device determined according to the second clock information is substantially the same as the specific description of determining the clock difference between the first bluetooth device and the second bluetooth device according to the first clock information in the first embodiment, and the specific description of the foregoing embodiment may be referred to and will not be repeated herein.
Step S302: and opening the receiving and transmitting window when the self clock reaches the opening time of the first receiving and transmitting window.
In this step, when the local clock of the first bluetooth device reaches the first transceiver window opening time, the first bluetooth device opens the transceiver window. Since the target data packet is already sent to the second bluetooth device via the BLE link in step S301, as described in detail in the first embodiment, the second bluetooth device may obtain the second transmit-receive window opening time according to the target data packet, so that the transmit-receive windows of the first bluetooth device and the second bluetooth device are simultaneously opened.
Step S303: a classical bluetooth link is established with the second bluetooth device via the transceiving window.
In this step, the transceiver windows of the first bluetooth device and the second bluetooth device are opened simultaneously, so that the construction data of the classical bluetooth link can be exchanged through the transceiver windows at this time, and the classical bluetooth link between the first bluetooth device and the second bluetooth device can be established according to the construction data.
Compared with the prior art, in the classical bluetooth link construction method provided by the second embodiment of the present application, under the condition that the first bluetooth device and the second bluetooth device have established a BLE link, the first bluetooth device directly transmits a target data packet to the second bluetooth device through the BLE link, the second bluetooth device can determine the opening time of the transceiver window according to the first clock information and the opening time of the first transceiver window contained in the target data packet and in combination with the local clock information in the second bluetooth device, the first bluetooth device opens the transceiver window when the own clock reaches the opening time of the first transceiver window, and can exchange the classical bluetooth link data packet with the second bluetooth device through the transceiver window, so that the classical bluetooth link is established, and the first bluetooth device and the second bluetooth device simultaneously open the transceiver window at the same time, thereby reducing the delay of the classical bluetooth link construction process; in addition, the Page and Page Scan processes in the traditional technology are omitted, and the energy consumption can be effectively reduced.
An embodiment III of the present application relates to a Bluetooth device, as shown in FIG. 4, including: the signal transceiver module 401, where the signal transceiver module 401 is configured to receive, via a BLE link, a target data packet sent by another bluetooth device, where the target data packet includes a first transceiver window opening time, first clock information of the other bluetooth device, a classical bluetooth address of the current bluetooth device, and a logical address of a classical bluetooth allocated to the other bluetooth device;
the operation module 402 is configured to determine a clock difference between the first bluetooth device and the second bluetooth device according to the first clock information, and determine a second transceiver window opening time and a frequency hopping point according to the clock difference, the first transceiver window opening time, the classical bluetooth address, and the logical address;
the link construction module 403 is configured to open a transceiver window when the own clock reaches a second transceiver window opening time, and establish a classical bluetooth link with another bluetooth device through the transceiver window.
Compared with the prior art, in the bluetooth device provided in the third embodiment of the present application, under the condition that the current bluetooth device has established a BLE link with another bluetooth device, the current bluetooth device directly receives a target data packet sent by the other bluetooth device through the BLE link, according to first clock information included in the target data packet, in combination with local clock information in the current bluetooth device, a clock difference between the other bluetooth device and the current bluetooth device can be determined, according to the clock difference and a first transceiver window opening time based on a clock of the other bluetooth device, the current bluetooth device can determine a second transceiver window opening time based on the clock of the current bluetooth device, when the clock of the current bluetooth device reaches the second transceiver window opening time, the current bluetooth device can switch with the other bluetooth device through the transceiver window, thereby establishing a classical bluetooth link, and the current bluetooth device and the other bluetooth device can simultaneously open the transceiver window at the same time, so as to reduce delay of a classical bluetooth link construction process; in addition, the Page and Page Scan processes in the traditional technology are omitted, and the energy consumption can be effectively reduced.
