Description
Technical Field
The present invention relates to a method of controlling a Bluetooth device, and more particularly, to a method of controlling power saving (power conservation) of a Bluetooth device.
Background
Bluetooth devices can operate in two main states: a standby state (standby state) and an online state (connection state). Furthermore, during the transition from the standby state to the online state, there are 7 sub-states (for searching for bluetooth devices or creating connections) including: page (page), page scan (page scan), inquiry (inquiry), inquiry scan (inquiry scan), master response (master response), slave response (slave response), and inquiry response (inquiry response). For example, in a page scan, a slave device (slave) listens for its own Device Access Code (DAC) for the duration of the scan window; in inquiry scans, a bluetooth device listens for inquiries from other devices for the duration of a scan window. Furthermore, the bluetooth device may be in any one of the following four modes in the online charging state: active mode (active mode), hold mode (hold mode), sniff mode (sniff mode) and park mode (park mode). For example, in active mode, a master (master) and a slave actively participate in a channel by listening, transmitting or receiving packets (packets); in the sleep mode, the slave does not listen on every slot (slot) for information that the master is sending to the slave, but only on specific slots.
In general, Power may be saved (Power) when a bluetooth device operates in a sleep mode. However, when the bluetooth device leaves or re-enters (re-enter) the sleep mode, some preparatory work needs to be performed. These preparations will consume a fixed power supply and this is a significant disadvantage if the bluetooth device frequently leaves or re-enters the sleep mode (wasting power supply to the bluetooth device when performing the preparations). Fig. 1 is a timing diagram of operations performed by a related art bluetooth device. As shown in fig. 1, the bluetooth device operates in a sleep mode 107. When the bluetooth device leaves the sleep mode 107, it first performs a wakeup (wakeup) preparation 105, and then it will wake up to perform some connection operations 101 or 103, such as checking the connection status or exchanging information. The bluetooth device will then perform sleep preparation 106 before it re-enters sleep mode 107. Since the bluetooth device frequently switches between the sleep mode and the awake mode, the preparation performed during the switching process consumes a certain amount of power, shortening the life of the battery in the bluetooth device.

Thus, if one device is coupled to another device, that connection may be through a direct electrical connection, or through an indirect electrical connection via other devices and connections.
In order to make the aforementioned objects, features and advantages of the present invention comprehensible, embodiments accompanied with figures are described in detail below.
Fig. 2 is a schematic diagram for explaining a bluetooth system 200 according to an embodiment of the present invention. The bluetooth system 200 includes a bluetooth device 110 and a remote device (remote device) 180. The bluetooth device 110 may be a mobile device such as a cellular phone, a tablet computer, or a notebook computer. The remote device 180 may be another electronic device having bluetooth functionality. In this embodiment, the bluetooth device and the remote device may be collectively referred to as a wireless device. As shown in fig. 2, the bluetooth device 110 includes at least an antenna (antenna)120, a radio frequency (radio frequency) module 130, and a baseband module (baseband module) 140. In some embodiments, the bluetooth device 110 may further include other components (components), such as a touch panel (touch panel), a touch module (touch module), a processor (processor), a speaker (speaker), a battery, and a housing (not shown in the figure). The present invention is not limited as to the type of antenna 120. For example, the antenna 120 may be a monopole antenna (monopole antenna), a dipole antenna (dipolatenna), a loop antenna (loop antenna), a Planar Inverted F Antenna (PIFA), a patch antenna (patch antenna), or a chip antenna (chip antenna). The rf module 130 is coupled to the antenna 120. The rf module 130 includes a bluetooth module (not shown) for processing bluetooth signals and transmitting (transmit) or receiving (receive) the bluetooth signals through the antenna 120. The baseband module 140 includes a controller 150 for controlling the rf module 130. In some embodiments, controller 150 may be implemented using hardware (e.g., a processing device) or software (e.g., program code stored in a non-transitory computer-readable medium and executed by a processing device). Generally, the controller 150 is configured to perform the method of the present invention. The following embodiment will describe in detail how the controller 150 controls the operations of the bluetooth device 110 and the rf module 130.
Fig. 3 is a diagram illustrating the operation of the bluetooth device 110 (e.g., the rf module 130 in the bluetooth device 110) on a time axis according to an embodiment of the present invention. Please refer to fig. 2 and fig. 3 together. In a preferred embodiment, controller 150 controls rf module 130 to establish a Bluetooth link between Bluetooth device 110 and remote device 180. Remote device 180 may also include an antenna and radio frequency module (not shown) for wireless communication. The bluetooth device 110 is then further controlled to enter a sniff mode and to process (handle) a sniff anchor point 210. Here, bluetooth device 110 will first perform a wakeup operation 250, then handle the listening trace 210 and some connection operations (e.g., first wakeup operation 230), and second perform sleep preparation 260. It should be noted that the above operations need not be performed in sequence. In some embodiments, the first wake-up operation 230 may be a page scan or an inquiry scan. The processing of the listening anchor 210 and its subsequent listening attempt (during a short period of time 220 after the listening trace 210) may be considered another wake-up operation that is different from the first wake-up operation 230. In some embodiments, bluetooth device 110 (e.g., rf module 130 therein) exchanges packets (packets) with remote device 180 during a short period of time 220 after listening for a dot 210. As shown in fig. 3, initially, bluetooth device 110 (e.g., rf module 130 therein) operates in sleep mode 270 to conserve power. During the sleep mode 270, the bluetooth device 110 may use a Low Power Oscillator (LPO) instead of the working oscillator. In some embodiments, wake up preparation 250 includes a clock settling count (clock settling count) and/or a clock compensation (clock compensation). The connection operation or the wake-up operation may be a process of listening to the anchor point 210, a listening attempt, a page scan, and/or an inquiry scan. After performing the above operations, the rf module 130 may perform sleep preparation 260 and then enter the sleep mode 270 again to save power. However, the intercept anchor 210 may be replaced by other operations. In other words, in one embodiment of the invention, at least two wake-up operations may be performed between wake-up preparation 250 and sleep preparation 260. Furthermore, since the at least two wake-up operations may occur simultaneously (coincide) or aligned with each other (align wireless other), it is not necessarily the operation of the wireless link (e.g., operation in listening mode) during the wake-up operation, and it is possible that all are the operation in non-link mode (e.g., BT inquiry scan, BT page scan, BLEadvertise, BLE scan or BLE initial, etc.). In an embodiment of the present invention, the wireless device may include at least two radios, wherein the at least two wake-up operations include at least one operation performed by each radio. In an embodiment, the at least two wireless modules include at least one of a bluetooth module, a bluetooth low energy module, and a Wi-Fi module. In another embodiment, the wireless device may have two different modes, in other words, the wireless device may operate in two modes, and the at least two wake-up operations comprise at least one operation in each mode. In one embodiment, the two modes include a Bluetooth mode and a Bluetooth low energy mode. In a preferred embodiment of the invention, the wireless device may include an arbiter (arbiter) to arrange (array) operation from different radios or different modes in the wireless device. For example, a first operation from one of the at least two wireless modules and a second operation from another wireless module are processed by the arbiter.
In a preferred embodiment of the present invention, at least two wake-up operations, including the processing of the listening dots 210 and the first wake-up operation 230, are performed centrally between the wake-up preparation 250 and the sleep preparation 260. It is noted that bluetooth device 110 (e.g., RF module 130 therein) does not enter any sleep mode 270 between wakeup prepare 250 and sleep prepare 260. Once the bluetooth device 110 and the RF module 130 therein wake up, the at least two wake-up operations are collectively performed between the wake-up preparation 250 and the sleep preparation 260. In this embodiment, the processing of the listening anchor 210 is close in time to the first wake-up operation 230, and the execution sequence is not limited. That is, the process of listening to the anchor point 210 may be located before or after the first wake-up operation 230. The requirements are as follows: the at least two wake-up operations are adjacent to each other when represented on a time axis. Thus, bluetooth device 110 (e.g., RF module 130 therein) may avoid switching (switch) between sleep mode and awake mode too frequently. Furthermore, multiple adjacent wake-up operations may share one wake/sleep preparation. For example, the listening anchor 210 and the first wake operation 230 may share wake up preparation 250 and sleep preparation 260. Therefore, the number of times of waking up/sleeping preparation can be made as small as possible, and the power consumption of the bluetooth device 110 in the present invention can be effectively reduced.
In some embodiments, the first wake-up operation 230 is a Bluetooth operation, a Bluetooth Low Energy (BLE) operation, or a Wi-Fi operation. The BLE operation may be performed by different modes of the bluetooth device or by a co-resident (co-located) bluetooth device. For example, the BLE operations may include BLE advertisement (advertisement), BLE scan (scan), and BLE initiated connection (initiate). The BLE advertisement, BLE scan, and BLE enable connection may be performed in sequence. In some embodiments, the Wi-Fi operation includes Wi-Fi beacon transmission (beacon transmission). In some embodiments, this Wi-Fi operation may be replaced by operation of other radio frequency signal standards.
In some embodiments, the wake-up operation may be performed periodically. In order to centrally arrange the wake-up operation and achieve a power saving (power saving) effect, the interval of the wake-up operation should be appropriately adjusted. Please refer to the following examples.
Fig. 4 is another diagram illustrating the operation of the bluetooth device 110 (e.g., the rf module 130 therein) on a time axis according to an embodiment of the present invention. To simplify the diagram, wake up preparation 250 and sleep preparation 260 are omitted in fig. 4. One skilled in the art will readily appreciate that wake preparation 250 is always performed during the transition of sleep mode 270 to any wake operation, and that sleep preparation 260 is always performed during the transition of any wake operation to the sleep mode 270. As shown in fig. 4, the listening anchor 210 is periodically processed at intervals of a first time period T1, and the first wake-up operation 230 is periodically performed at intervals of a second time period T2. In the present embodiment, the first time period T1 is substantially equal to the second time period T2. According to the arrangement of fig. 4, the listening anchor 210 is adjacent in time to the first wake-up operation 230 in each cycle of cycles. In the present embodiment, the number of times of wake-up/sleep preparation is performed is as small as possible, and power consumption of the bluetooth device 110 is effectively reduced.
Fig. 5 is another diagram illustrating the operation of the bluetooth device 110 (e.g., the rf module 130 therein) on a time axis according to an embodiment of the present invention. Fig. 5 is similar to fig. 4.

In the present embodiment, the time point of processing the listening anchor 210 is synchronized with the time point of executing the first wake-up operation 230, in other words, the first wake-up operation 230 and the listening anchor 210 are aligned with each other, so that the number of times of wake-up/sleep preparation is performed is as small as possible, and the power consumption of the bluetooth device 110 is effectively reduced. Other features of the embodiment shown in fig. 5 are the same as in fig. 4. Accordingly, both embodiments can achieve similar effects.

In the present embodiment, the time point of processing the listening anchor 210 is synchronized with the time point of executing the first wake-up operation 230, in other words, the first wake-up operation 230 and the listening anchor 210 are aligned with each other, so that the number of times of wake-up/sleep preparation is performed is as small as possible, and the power consumption of the bluetooth device 110 is effectively reduced. Other features of the embodiment shown in fig. 6 are the same as those of fig. 4. Accordingly, both embodiments can achieve similar effects.
In some embodiments, when the time interval of the first wake-up operation 230 and the time interval of the listening anchor 210 are equal to or have a multiple relationship with each other, the first wake-up operation 230 is synchronized with the time point adjustment of the listening anchor 210 and then the first wake-up operation 230 and the listening anchor 210 are performed, in other words, the first wake-up operation 230 and the listening anchor 210 are aligned with each other to reduce the number of sleep preparations and wake preparations.
Fig. 7 is another diagram illustrating the operation of the bluetooth device 110 (e.g., the rf module 130 therein) on a time axis according to an embodiment of the present invention. Fig. 7 is similar to fig. 3.

Similarly, bluetooth device 110 (e.g., RF module 130 therein) does not enter any sleep mode 270 between wakeup prepare 250 and sleep prepare 260. In some embodiments, the first wake-up operation 230 is a page scan and the second wake-up operation 240 is an inquiry scan. The processing of the listening anchor 210, the first wake-up operation 230, and the second wake-up operation 240 are adjacent to each other on the time axis, and the execution order is not limited by the present invention. In the present embodiment, the number of times of waking up/sleeping preparation is performed is as small as possible, and power consumption of the bluetooth device 110 is effectively reduced. Similarly, 4 or more wake-up operations may be performed between wake-up preparation 250 and sleep preparation 260, and in particular, embodiments of the present invention are not limited. Other features of the embodiment shown in fig. 7 are the same as in fig. 3. Accordingly, both embodiments can achieve similar effects.
Fig. 8 is another diagram illustrating the operation of the bluetooth device 110 (e.g., the rf module 130 therein) on a time axis according to an embodiment of the present invention.

Fig. 8 differs from the embodiment shown in fig. 4 in that the embodiment shown in fig. 8 includes a second wake-up operation 240, and the second wake-up operation 240 is performed periodically at intervals of a third time period T3. In some embodiments, the first time period T1 is substantially equal to the third time period T3. In some embodiments, the first time period T1 is approximately a multiple of the third time period T3. In other embodiments, the third time period T3 is approximately a multiple of the first time period T1. Wherein the multiple can be any positive integer greater than 1, such as 2, 3, 4, or 5, etc. In the present embodiment, the time point of the listening anchor 210, the time point of the first wake-up operation 230, and the time point of the second wake-up operation 240 are synchronized, so that the number of times of wake-up/sleep preparation is performed is as small as possible, and the power consumption of the bluetooth device 110 is effectively reduced. Similarly, the present invention may also include 4 or more wake-up operations, and the wake-up operations are periodically performed at intervals, and each interval may be appropriately adjusted as described above. Other features of the embodiment shown in fig. 8 are the same as in fig. 4. Accordingly, both embodiments can achieve similar effects.
Fig. 9 is a flowchart illustrating a method of controlling a bluetooth device according to an embodiment of the present invention. Initially, in step S910, a bluetooth link is established. In step S920, the bluetooth device is controlled to enter a listening mode. In step S930, the listening anchor is processed after wake-up preparation and before sleep preparation. Finally, in step S940, the wakeup operation is processed between wakeup preparation and sleep preparation. In some embodiments, the wake-up operation is a bluetooth operation, a Bluetooth Low Energy (BLE) operation, or a Wi-Fi operation. The BLE operation may be performed by different modes of the bluetooth device or by a co-resident (co-located) bluetooth device. For example, the BLE operations may include BLE advertising, BLE scanning, and BLE enabled connections. The BLE advertisement, BLE scan, and BLE enable connection may be performed sequentially.

In some embodiments, the inventive method further comprises the step of handling a further wake-up operation between wake-up preparation and sleep preparation. It should be noted that the above steps need not be performed in the above order. In addition, each of the details of the embodiments shown in fig. 2-8 may be applied to the method shown in fig. 9.

When the program code is loaded into and executed by a machine, such as a computer, the machine becomes an apparatus for practicing the methods. The methods of the present invention may also be practiced via program code transmitted over transmission media such as wire or cable, fiber optics, or any other form of transmission.
