Description

Bluetooth device and method for controlling Bluetooth device or wireless device

technical field

The present invention relates to a method for controlling a Bluetooth device, and more particularly, to a method for controlling power conservation of a Bluetooth device.

Background technique

A Bluetooth device can operate in two main states: standby state and connection state. In addition, during the transition from standby state to online state, there are 7 sub-states (used to search for Bluetooth devices or create connections), including: paging (page), page scanning (pagescan), query (inquiry), query scanning (inquiry scan), master response (master response), slave response (slave response), and query response (inquiry response). For example, in a paging scan, the slave listens for its own device access code (DAC) for the duration of the scan window; in an inquiry scan, the Bluetooth device listens for the duration of the scan window. Queries from other devices. In addition, the Bluetooth device can be in any one of the following four modes in the connection state: active mode, hold mode, sniff mode and park mode. For example, in active mode, the master device (master) and slave device actively participate in a channel by listening, transmitting or receiving data packets (packet); in sleep mode, the slave device does not ) to listen to the information sent by the master device to the slave device, but only listen to these information on specific time slots.

Generally, power can be saved when a Bluetooth device operates in a sleep mode. However, when a Bluetooth device leaves or re-enters this sleep mode, some preparations need to be performed. These preparations will consume a constant amount of power, and this will be a significant disadvantage if the Bluetooth device leaves and re-enters this sleep mode frequently (wasting the power of the Bluetooth device while performing these preparations). FIG. 1 is a timing diagram of operations performed by a prior art Bluetooth device. As shown in FIG. 1 , the Bluetooth device operates in sleep mode 107 . When a Bluetooth device leaves sleep mode 107, it first performs wakeup preparations 105, then it wakes up to perform some connection operations 101 or 103, such as checking connection status or exchanging information. Afterwards, before the Bluetooth device re-enters sleep mode 107, it will perform sleep preparations 106. Since the Bluetooth device frequently switches between the sleep mode and the wake-up mode, the preparation work performed during the switching process consumes a certain amount of power, which shortens the life of the battery in the Bluetooth device.

In order to make the above-mentioned objects, features and advantages of the present invention more comprehensible, the following specific examples are given together with the attached drawings for a detailed description as follows.

According to an embodiment of the present invention, FIG. 2 is a schematic diagram illustrating a Bluetooth system 200 . The Bluetooth system 200 includes a Bluetooth device 110 and a remote device (remote device) 180 . The Bluetooth device 110 can 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 with 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 120 , a radio frequency (radio frequency) module 130 and a baseband module (baseband module) 140 . In some embodiments, the Bluetooth device 110 may also include other components, such as a touch panel (touch panel), a touch module (touch module), a processor (processor), a speaker (speaker), a battery and a casing ( not shown in the figure). The present invention does not limit the type of the antenna 120 . For example, the antenna 120 may be a monopole antenna (monopole antenna), a dipole antenna (dipole antenna), a loop antenna (loop antenna), a planar inverted F antenna (planarinverted F antenna, PIFA), a patch antenna (patch antenna) Or chip type antenna (chipantenna). The radio frequency module 130 is coupled to the antenna 120 . The radio frequency module 130 includes a bluetooth module (not shown), which is used to process the bluetooth signal, and transmit (transmit) or receive (receive) the bluetooth signal through the antenna 120 . The baseband module 140 includes a controller 150 for controlling the radio frequency module 130 . In some embodiments, the controller 150 may be implemented using hardware (such as a processing device) or software (such as 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 embodiments will describe in detail how the controller 150 controls the operations of the Bluetooth device 110 and the radio frequency module 130 .

According to an embodiment of the present invention, FIG. 3 is a schematic diagram illustrating the operation of the Bluetooth device 110 (such as the radio frequency module 130 in the Bluetooth device 110 ) on the time axis. Please refer to Figure 2 and Figure 3 together. In a preferred embodiment, the controller 150 controls the radio frequency module 130 to establish a Bluetooth link between the Bluetooth device 110 and the remote device 180 . Remote device 180 may also include an antenna and radio frequency module (not shown) for wireless communication. Then, further control the Bluetooth device 110 to enter the sniff mode, and handle the sniff anchor point 210 . Here, the Bluetooth device 110 will first perform a wakeup operation 250 , then process the listening profile 210 and some connection operations (such as the first wakeup operation 230 ), and then perform a sleep preparation 260 . It should be noted that the above operations do not need to 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 point 210 and its subsequent listening attempt (during the short time period 220 after the listening trace point 210) can be viewed as another wakeup operation different from the first wakeup operation 230 . In some embodiments, during a short time period 220 after the listening point 210 , the Bluetooth device 110 (eg, the radio module 130 therein) exchanges packets with the remote device 180 . As shown in FIG. 3 , initially, the Bluetooth device 110 (such as the radio frequency module 130 therein) operates in a sleep mode 270 to save 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 clock settling count and/or clock compensation. A connection operation or wakeup operation may be a processing of the listening anchor 210, a listening attempt, a page scan and/or an inquiry scan. After performing the above operations, the radio frequency module 130 can prepare for sleep 260 and then enter the sleep mode 270 again to save power. However, Intercept Anchor 210 may be replaced by other operations. In other words, in an embodiment of the present invention, at least two wake-up operations may be performed between the wake-up preparation 250 and the sleep preparation 260 . In addition, since the at least two wake-up operations can occur simultaneously (coincide) or align with each other (align with each other), therefore, during the wake-up operation, it is not necessarily an operation of the wireless link (for example, an operation in a listening mode), it is possible All are non-link mode operations (for example, BT inquiry scan, BT page scan, BLE advertise, BLE scan or BLE initiate, etc.). In an embodiment of the present invention, the wireless device may include at least two wireless modules, wherein the at least two wake-up operations include at least one operation performed by each wireless module. 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 include at least one operation in each mode. In an embodiment, the two modes include Bluetooth mode and Bluetooth low energy mode. In a preferred embodiment of the present invention, the wireless device may include an arbiter to arrange operations from different wireless modules or different modes in the wireless device. For example, the arbiter processes the first operation from one of the at least two wireless modules and the second operation from the other wireless module.

In a preferred embodiment of the present invention, at least two wakeup operations including the processing of the listening trace 210 and the first wakeup operation 230 are collectively performed between the wakeup preparation 250 and the sleep preparation 260 . It should be noted that the Bluetooth device 110 (such as the RF module 130 therein) does not enter any sleep mode 270 between the wake-up preparation 250 and the sleep preparation 260 . Once the Bluetooth device 110 and the RF module 130 therein wake up, the at least two wake-up operations are intensively performed between the wake-up preparation 250 and the sleep preparation 260 . In this embodiment, the processing of the listening anchor 210 is close to the first wake-up operation 230 in time, and the execution sequence is not limited. That is, the processing of the listening anchor 210 may be located before or after the first wake-up operation 230 . The requirement is that the at least two wakeup operations are adjacent to each other when represented on the time axis. Therefore, the Bluetooth device 110 (such as the RF module 130 therein) can avoid switching between the sleep mode and the wake-up mode too frequently. In addition, multiple adjacent wakeup operations can share a wakeup/sleep preparation. For example, listening anchor 210 and first wakeup operation 230 may share wakeup preparation 250 and sleep preparation 260 . Therefore, the number of wake-up/sleep preparations can be reduced as much 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. This BLE operation can be performed by a different mode of the Bluetooth device or by co-located Bluetooth devices. For example, the BLE operation may include BLE advertisement (advertise), BLE scan (scan) and BLE initiate connection (initiate). BLE Advertisement, BLE Scan and BLE Initiate Connection can be performed sequentially. In some embodiments, the Wi-Fi operation includes Wi-Fi beacon transmission. In some embodiments, this Wi-Fi operation may be superseded by operation of other RF signal standards.

In some embodiments, wake-up operations may be performed periodically. In order to centrally arrange the wake-up operations and achieve the effect of power conservation, the interval of the wake-up operations should be adjusted appropriately. Please refer to the following examples.
