The invention provides a Bluetooth remote controller recovery system, which comprises display equipment, a Bluetooth remote controller and a smart phone, and is characterized in that the display equipment is connected with the Bluetooth remote controller;
the interactive process of the Bluetooth remote controller recovery system is as follows:
after the display equipment is started, a first Bluetooth module of the display equipment broadcasts a Bluetooth awakening broadcast packaged with an MAC address of the display equipment to the outside;
if the remote control instruction of the remote controller is not detected within the preset time of the display equipment, the display equipment displays a two-dimensional code, and the two-dimensional code contains the MAC address of the display equipment
The mobile phone scans the two-dimensional code to obtain the MAC address of the display equipment, establishes a virtual machine, simulates a first Bluetooth module of the display equipment by using hardware of the mobile phone, and broadcasts a Bluetooth awakening broadcast packaged with the MAC address to the outside; outputting prompt information for guiding a user to walk in an indoor space provided with display equipment in the process of broadcasting the Bluetooth awakening broadcast by the mobile phone;
after the Bluetooth remote controller enters a standby state, a second Bluetooth module of the Bluetooth remote controller enters a low power consumption mode, and the second Bluetooth module only receives Bluetooth awakening broadcast when in the low power consumption mode; when the Bluetooth remote controller receives the Bluetooth awakening broadcast, the second Bluetooth module awakens the Bluetooth remote controller to enter a working mode from a low power consumption mode, and the Bluetooth remote controller outputs preset positioning prompt information.
The invention also provides a Bluetooth remote controller retrieving method, which is applied to a Bluetooth remote controller retrieving system, wherein the Bluetooth remote controller retrieving system comprises display equipment, a Bluetooth remote controller and a smart phone; the display equipment can be an intelligent television or a projector, a Bluetooth module is arranged in the Bluetooth remote controller, the Bluetooth remote controller has a Bluetooth signal receiving and transmitting function, and the intelligent mobile phone is a touch screen mobile phone used by a user.
Referring to fig. 2, the bluetooth remote controller retrieving method includes the following steps:
step S10, after the display device is started, the first Bluetooth module of the display device broadcasts the Bluetooth awakening broadcast packaged with the MAC address of the display device;
after the display device is powered on, the display device obtains a Media Access Control Address (MAC Address) of the display device in advance, and encapsulates the MAC Address into a data packet of a bluetooth wakeup broadcast to be broadcasted, wherein a bluetooth wakeup broadcast user wakes up a bluetooth remote controller in a dormant or standby state, and the bluetooth wakeup broadcast is broadcasted outwards by a first bluetooth module of the display device.
And step S20, if the remote control instruction of the remote controller is not detected within the preset time length of the display equipment, the display equipment displays a two-dimensional code, and the two-dimensional code comprises the MAC address of the display equipment.
After a first Bluetooth module of the display device broadcasts a Bluetooth awakening broadcast with a self MAC address, the duration of a remote control instruction of a remote controller is synchronously started to be not detected by the display device, if the duration of the remote control instruction of the remote controller is not detected by the display device and is greater than preset duration, the fact that a user opens the display device for a long time is shown, the display device is not controlled by the Bluetooth remote controller matched with the display device all the time, the Bluetooth remote controller is likely to be lost, the user cannot find the display device, the display device displays a two-dimensional code at the moment, the user can scan the code based on the mobile phone of the user, and the MAC address of the display device is contained in the two-dimensional code.
Step S30, the mobile phone scans the two-dimensional code, obtains the MAC address of the display device, establishes a virtual machine, simulates the first Bluetooth module of the display device by using the hardware of the mobile phone, and broadcasts the Bluetooth awakening broadcast encapsulated with the MAC address to the outside; outputting prompt information for guiding a user to walk in an indoor space provided with display equipment in the process of broadcasting the Bluetooth awakening broadcast by the mobile phone;
after the user operates the mobile phone to scan the two-dimensional code, the mobile phone may enter a URL (uniform resource locator) address corresponding to the two-dimensional code, thereby obtaining the MAC address of the display device. Then the mobile phone establishes a virtual machine in a memory of the mobile phone, and utilizes hardware of the mobile phone to simulate a first Bluetooth module of the display device, namely, a hardware module of the first Bluetooth module is simulated in a virtual machine software mode, so that the first Bluetooth module based on virtual machine simulation of the mobile phone broadcasts a Bluetooth awakening broadcast encapsulated with an MAC address outwards, which is equivalent to that a user utilizes the mobile phone to simulate the Bluetooth awakening broadcast of the display device outwards. Because the display device broadcasts the Bluetooth awakening broadcast outwards and cannot awaken the Bluetooth remote controller, the Bluetooth remote controller is probably beyond the effective awakening function range of the Bluetooth awakening broadcast of the display device, a virtual machine of the mobile phone is activated to simulate the display device to broadcast the Bluetooth awakening broadcast outwards, and the mobile phone can be more easily close to the Bluetooth remote controller during moving to awaken the Bluetooth remote controller based on the Bluetooth awakening broadcast.
Specifically, referring to fig. 3, the step of establishing a virtual machine by the mobile phone in step S30, and using the first bluetooth module of the hardware analog display device of the mobile phone to broadcast the bluetooth wakeup broadcast encapsulated with the MAC address to the outside includes:
step A1, the mobile phone starts a virtual machine process, establishes a virtual machine, and sets a virtual Bluetooth front end in the virtual machine; setting a virtual Bluetooth rear end for a third Bluetooth module of the mobile phone; the virtual Bluetooth front end of the virtual machine in the mobile phone and the virtual Bluetooth rear end of the third Bluetooth module perform cross-system communication in a shared memory mode;
step A2, the mobile phone assigns the hardware address of the virtual Bluetooth module in the virtual machine to the MAC address so as to simulate the first Bluetooth module of the display device; the mobile phone triggers the virtual Bluetooth module to send a control instruction of Bluetooth awakening broadcast so that the virtual Bluetooth front end can send the control instruction to the virtual Bluetooth rear end of the third Bluetooth module to control the third Bluetooth module to call a corresponding Bluetooth driving function in the kernel, and therefore the third Bluetooth module can broadcast the Bluetooth awakening broadcast packaged with the MAC address outwards.
By arranging the virtual Bluetooth front end in the virtual machine and the virtual Bluetooth rear end in the third Bluetooth module of the mobile phone, cross-system communication between the virtual machine in the mobile phone and the third Bluetooth module in the mobile phone is realized, and Bluetooth awakening broadcast of the MAC address of the display equipment packaged in the mobile phone analog broadcast is realized.
Step S40, after the Bluetooth remote controller enters a standby state, a second Bluetooth module of the Bluetooth remote controller enters a low power consumption mode, and the second Bluetooth module only receives Bluetooth awakening broadcast when in the low power consumption mode; when the Bluetooth remote controller receives the Bluetooth awakening broadcast, the second Bluetooth module awakens the Bluetooth remote controller to enter a working mode from a low power consumption mode, and the Bluetooth remote controller outputs preset positioning prompt information.
The Bluetooth remote controller is not completely powered off after entering the standby state, the main control chip of the Bluetooth remote controller is in a low-power consumption standby operation state, and meanwhile, the main control chip supplies power to the second Bluetooth module so that the second Bluetooth module is in the low-power consumption operation state, the second Bluetooth module is in the low-power consumption mode operation state, the second Bluetooth module can only receive Bluetooth awakening broadcast broadcasted by the matched display equipment at the moment, and other control instructions are not responded. When the Bluetooth remote controller receives the Bluetooth awakening broadcast, the second Bluetooth module awakens the Bluetooth remote controller, the Bluetooth remote controller enters a working mode from a low power consumption mode, the Bluetooth remote controller outputs preset positioning prompt information, the positioning prompt information can be one or more of sounding, lighting and vibration, the purpose is to prompt the position of the Bluetooth remote controller of a user, and the user can find the Bluetooth remote controller conveniently.
In this embodiment, when the display device cannot wake up the bluetooth remote controller through the bluetooth wake-up broadcast, the user is guided to scan the two-dimensional code output by the display device by using the own mobile phone, so as to establish a virtual machine for simulating the first bluetooth module of the display device through the mobile phone, and to broadcast the bluetooth wake-up broadcast encapsulated with the MAC address to the outside; for the bluetooth remote controller, no matter the bluetooth remote controller is a bluetooth wake-up broadcast broadcasted by the display device or a bluetooth wake-up broadcast sent by the mobile phone through the virtual machine, as long as the bluetooth remote controller receives the bluetooth wake-up broadcast, the second bluetooth module wakes up the bluetooth remote controller to enter a working mode from a low power consumption mode, and the bluetooth remote controller outputs preset positioning prompt information; furthermore, a user carrying the mobile phone walks around outdoors, the effective range of the Bluetooth awakening broadcast sent by the virtual machine of the mobile phone traverses all possible indoor areas of the Bluetooth remote controller, so that the mobile phone can awaken the Bluetooth remote controller conveniently based on the virtual machine, the Bluetooth remote controller is controlled to actively output preset positioning prompt information, the user is effectively guided to find the Bluetooth remote controller, the Bluetooth remote controller is not easy to lose, and the user can quickly find the Bluetooth remote controller.
In addition, before the display device displays the two-dimensional code, the method for retrieving the bluetooth remote controller further comprises the following steps:
step B, the display equipment increases the power of the first Bluetooth module, and the display equipment controls the first Bluetooth module to broadcast the Bluetooth awakening broadcast packaged with the MAC address of the display equipment outwards with the increased power; the display device counts the time length of the remote control command of the remote controller is not detected.
After a first Bluetooth module of display equipment broadcasts a Bluetooth awakening broadcast with a self MAC address, during the period that the display equipment does not detect the duration of a remote control command of a remote controller and is less than or equal to the preset duration, the display equipment increases the power of the first Bluetooth module, enlarges the awakening effective range of the Bluetooth awakening broadcast which is encapsulated with the MAC address of the display equipment and broadcasts outwards, and tries to awaken the Bluetooth remote controller once after expanding the range before the display equipment outputs a two-dimensional code, so that the process that a user operates a mobile phone to establish a virtual machine and simulate to awaken the Bluetooth remote controller is avoided as much as possible.
Further, in another embodiment of the bluetooth remote controller retrieving method according to the present invention, the step of scanning the two-dimensional code by the mobile phone in step S30 and acquiring the MAC address of the display device includes:
step C1, the mobile phone scans the two-dimensional code to access the URL address pointed by the two-dimensional code, and the initial state of the MAC address in the URL address is a shielding state;
the mobile phone scans the two-dimensional code to access the URL address pointed by the two-dimensional code, the MAC address in the URL address cannot be obtained at first, the initial state of the MAC address is a shielding state, and the situation that the MAC address of the display device can be obtained by scanning the two-dimensional code or remotely scanning an image of the two-dimensional code by the mobile phone of any person is prevented.
Step C2, the display device detects that the URL address pointed by the two-dimensional code is accessed, the display device displays the preset random characters and starts a microphone of the display device, and the display device sends prompt information for prompting a user to read the preset random characters to the mobile phone;
the user scans the two-dimensional code based on the mobile phone to find back the Bluetooth remote controller, which may be false triggering of the user or illegal operation not of the user, so that in order to avoid the problems, before the mobile phone scans the two-dimensional code to obtain the MAC address of the display device, the display device performs field verification on the user of the mobile phone, the display device displays preset random characters and starts a microphone carried by the display device, and the display device sends prompt information for prompting the user to read the preset random characters aloud to the mobile phone; the preset random characters are not limited to Chinese, and can be one or more combinations of numbers, characters, symbols and letters, for example, the preset random characters are 'wind and sun beauty', the display device displays four characters of 'wind and sun beauty', and prompt information prompting a user to read the preset random characters is synchronously sent to the mobile phone.
Step C3, the display device collects the surrounding environment audio frequency, and carries on the voice recognition to the surrounding environment audio frequency to get the corresponding audio character; the display equipment compares the audio words with the preset random words, and if the audio words are matched with the preset random words, the display equipment adjusts the MAC address in the URL address to be in an accessible state so that the mobile phone can obtain the MAC address of the display equipment.
After the preset random characters are displayed on the display device, the microphone of the display device collects the surrounding environment audio to judge whether the user reads the preset random characters. The display device collects and identifies the surrounding environment audio based on the microphone to obtain audio words, when the audio words are matched with the preset random words, the content read aloud by the user is matched with the preset random words displayed by the display device, and the mobile phone scans the two-dimensional code at the site of the environment where the display device is located by the user, so that the user really intends and operates legally, the display device adjusts the MAC address in the URL address to be in an accessible state, and the mobile phone can obtain the MAC address of the display device. If the audio characters are not matched with the preset random characters, the user is not on site or is illegal operation, and the safety of the recovery function of the Bluetooth remote controller is improved in order to avoid the Bluetooth remote controller from being awakened by unnecessary Bluetooth awakening broadcast.
In addition, if the audio characters are matched with the preset random characters, the display equipment compares the surrounding environment audio frequency with the preset voiceprint, and if the surrounding environment audio frequency is matched with the preset voiceprint, the display equipment adjusts the MAC address in the URL address to be in an accessible state so that the mobile phone can obtain the MAC address of the display equipment.
Since the voiceprint comparison is added even if the operator of the two-dimensional code scanning mobile phone is on the site of the installation environment of the display device, after the audio characters are matched with the preset random characters, namely, the peripheral environment audio of the operator of the scanning mobile phone containing the two-dimensional code is compared with the preset voiceprint, if the peripheral environment audio is matched with the preset voiceprint, the fact that the operator of the scanning mobile phone containing the two-dimensional code is the user is indicated, the related operation searched by the Bluetooth remote controller is not illegal, at the moment, the display device adjusts the MAC address in the URL address to be in an accessible state, so that the mobile phone can acquire the MAC address of the display device, the identity verification of the operator of the scanning mobile phone containing the two-dimensional code is completed based on the voiceprint, and the triggering accuracy and the safety of searching by the Bluetooth remote controller are further improved.
In addition, the positioning prompt message comprises one or more of sounding, lighting and vibration;
after the step of outputting the preset positioning prompt message by the bluetooth remote controller, the method further comprises the following steps:
and D, when the acceleration unit time variation of the Bluetooth remote controller is larger than a preset acceleration value, the Bluetooth remote controller stops outputting the positioning prompt information.
After the bluetooth remote controller outputs the positioning prompt information, the user starts to search the target remote controller, and after the user finds the bluetooth remote controller outputting the positioning prompt information, the bluetooth remote controller does not need to continuously output the positioning prompt information, so that after the user finds the bluetooth remote controller outputting the positioning prompt information, the bluetooth remote controller stops outputting the positioning prompt information. Specifically, bluetooth remote controller output location suggestion information, can real-time detection self acceleration change condition, if bluetooth remote controller's acceleration unit interval variation is greater than predetermineeing the acceleration value, show that bluetooth remote controller's motion state changes, it is likely that the user finds and takes up bluetooth remote controller, bluetooth remote controller can stop output location suggestion information this moment, and then in time control bluetooth remote controller stops output location suggestion information, save bluetooth remote controller electric quantity, also avoid the location suggestion information of bluetooth remote controller output to influence the normal sight shadow of user and bluetooth remote controller use.
Further, in another embodiment of the bluetooth remote controller retrieving method of the present invention, the bluetooth remote controller retrieving method further includes:
step E1, after the Bluetooth remote controller enters the standby state, the Bluetooth remote controller detects whether the pre-stored local wake-up file is empty; if the local awakening file is not empty, the Bluetooth remote controller acquires a local MAC address in the local awakening file, wherein the local MAC address is the MAC address of the display equipment successfully matched with the Bluetooth remote controller; at most one local MAC address is stored in a local awakening file of the Bluetooth remote controller;
what use between the first Bluetooth module of display device and the second Bluetooth module of Bluetooth remote controller is Bluetooth 4.0BLE communication protocol, and Bluetooth 4.0 is a trinity Bluetooth, fuses traditional Bluetooth, Bluetooth low energy and high-speed Bluetooth technique together, and the Bluetooth of this three specification also can the exclusive use. In the application, the technology mainly applied is Bluetooth 4.0 low-power consumption Bluetooth, and the Bluetooth low-power consumption does not need to occupy too much bandwidth and has extremely low power consumption. Bluetooth 4.0BLE is suitable for a remote controller which is a Bluetooth device with long time and small data transmission quantity.
If the bluetooth remote controller has the paired external display device, the bluetooth remote controller may create a local wake-up file named wake _ on.ble locally, where the local wake-up file is used to store a Media Access Control (MAC) Address of the display device that the bluetooth remote controller has been paired to work, that is, the local wake-up file is not empty at this time, and the main Control chip of the bluetooth remote controller may write the local MAC Address into the second bluetooth module, so that the second bluetooth module may match the local MAC Address when receiving the bluetooth wake-up broadcast.
In an embodiment of the present application, if the bluetooth remote controller does not have a matching record of the display device, that is, the local wake-up file is empty, after the bluetooth remote controller is in the standby state, when the master control chip cannot find the local wake-up file with the local MAC address, the second bluetooth module matches the bluetooth wake-up broadcast of any bluetooth module of the same type, that is, the bluetooth wake-up broadcast of the same manufacturer as the second bluetooth module, it is not necessary to determine whether the MAC addresses in the bluetooth wake-up broadcast of the same manufacturer are matched, and the MAC address in the bluetooth wake-up broadcast of the same manufacturer is directly used as the local MAC address of the local wake-up file.
In step S40, when the bluetooth remote controller receives the bluetooth wakeup broadcast, the step of waking up the bluetooth remote controller by the second bluetooth module to enter the operating mode from the low power consumption mode includes:
step F1, when the Bluetooth remote controller receives the Bluetooth awakening broadcast, analyzing the Bluetooth awakening broadcast to obtain a broadcast MAC address in the Bluetooth awakening broadcast;
when the Bluetooth remote controller detects that the local awakening file is not empty, after the local MAC address in the local awakening file is acquired, when a second Bluetooth module of the Bluetooth remote controller receives a Bluetooth awakening broadcast sent by a display device or a mobile phone virtual machine simulating a first Bluetooth module, a main control chip of the Bluetooth remote controller analyzes the Bluetooth awakening broadcast. Specifically, the message format of the bluetooth wakeup broadcast is that a series of message contents sequentially include a header file field, a message length field, a manufacturer field and an MAC address field, wherein the header file field is 0x (hexadecimal), the message length field is 8 bits (binary), the manufacturer field is 24 bits (binary), the MAC address field is 56 bits (binary), and the key instruction field is 32 bits (binary). The analysis of the bluetooth wakeup broadcast by the main control chip of the bluetooth remote controller specifically includes sequentially extracting and identifying each field content in the message according to the message format, so that the main control chip of the bluetooth remote controller acquires the MAC address (namely, broadcast MAC address) in the bluetooth wakeup broadcast received by the second bluetooth module. For example, if the content of a message in a bluetooth wakeup broadcast is 0x0EFF004601F8DD97353AC4FFFFFFFF (hexadecimal), 0x is a header field, 0E is a message length field, FF0046 is a manufacturer field, 01F8DD97353AC4 is a MAC address field, and FFFFFFFF is a key instruction field.
Step F2, the Bluetooth remote controller compares the local MAC address with the broadcast MAC address, if the local MAC address is matched with the broadcast MAC address, the broadcast key instruction of the Bluetooth wake-up broadcast is obtained and identified;
only one local MAC address is stored in the local awakening file of the Bluetooth remote controller, namely the local MAC address in the local awakening file is the MAC address of the display device which is successfully paired recently by the second Bluetooth module of the Bluetooth remote controller. For example, the MAC address of the display device a is stored in the local wake-up file of the bluetooth remote controller, which indicates that the second bluetooth module of the bluetooth remote controller and the display device a are successfully paired, and if the second bluetooth module receives the MAC address of the new bluetooth wake-up broadcast in the standby state of the current bluetooth remote controller, the MAC address of the new bluetooth wake-up broadcast and the local MAC address of the display device a are compared, and if the local MAC address is matched with (if identical to) the MAC address of the new bluetooth wake-up broadcast, it indicates that the MAC address of the new bluetooth wake-up broadcast is sent by the display device a, and the main control chip of the bluetooth remote controller further analyzes the bluetooth wake-up broadcast sent by the display device a, so as to obtain and identify the broadcast key command in the bluetooth wake-up broadcast.
Step F3, if the broadcast key instruction is a preset power on/off instruction, the second Bluetooth module of the Bluetooth remote controller wakes up the Bluetooth remote controller to enter a working mode from a low power consumption mode.
In connection with the above example, if the broadcast key instruction is a preset power on/off instruction, indicating that the user has triggered the power on/off key of the display device a, the main control chip of the bluetooth remote controller controls the wakeup pin of the second bluetooth module to output a pull-down low level signal to the trigger pin, so as to trigger the power on/off key in the key board of the bluetooth remote controller, and achieve the same effect as that of the power on/off key output low level power on by the key board.
In addition, if the bluetooth wakeup broadcast is not the preset power on/off instruction, it indicates that although the bluetooth wakeup broadcast is sent by the display device a, the broadcast key instruction carried in the bluetooth wakeup broadcast is not the power on/off instruction for waking up the bluetooth remote controller.
In this embodiment, after the bluetooth remote controller enters the standby state, the main control chip of the bluetooth remote controller controls the second bluetooth module to enter the low power consumption mode, and the second bluetooth module only receives the bluetooth wakeup broadcast of the external display device when in the low power consumption mode; and a local wake-up file is creatively added in the Bluetooth remote controller, at most one local MAC address successfully matched with the Bluetooth of the display device is stored, only when the MAC address of the new Bluetooth wake-up broadcast is matched with the local MAC address, a broadcast key instruction in the Bluetooth wake-up broadcast is further acquired and identified, and finally, the broadcast key instruction is a preset power-on and power-off instruction, the main control chip of the Bluetooth remote controller controls the wake-up pin of the second Bluetooth module to output a pull-down low-level signal to the trigger pin so as to trigger the power-on and power-off keys in the key board, so that the display device wakes up the Bluetooth remote controller instrument in a low-power-consumption Bluetooth communication mode, and a user can effectively and reliably wake up the Bluetooth remote controller by scanning two-dimensional codes based on the display device or a mobile phone. Furthermore, the local awakening file is creatively arranged in the Bluetooth remote controller, and only one local MAC address successfully matched with the Bluetooth of the Bluetooth remote controller is stored in the local awakening file, so that the user is limited to awaken the Bluetooth remote controller only through the MAC address of the display equipment successfully matched with the Bluetooth remote controller at present, the Bluetooth remote controller is prevented from being awakened by display equipment with other MAC addresses or other key points by mistake, and the uniqueness and reliability of remote awakening of the Bluetooth remote controller by matching the display equipment are ensured.
In addition, the step of analyzing the bluetooth wakeup broadcast and acquiring the broadcast MAC address in the bluetooth wakeup broadcast includes:
g1, the Bluetooth remote controller analyzes the message of the Bluetooth awakening broadcast and extracts the broadcast manufacturer information of the manufacturer field in the Bluetooth awakening broadcast; the message content of the broadcast information is a message length field, a manufacturer field, an MAC address field and a key instruction field in sequence;
g2, comparing the broadcast manufacturer information with local manufacturer information prestored in the Bluetooth remote controller; if the broadcast manufacturer information is not matched with the local manufacturer information, the Bluetooth remote controller discards the Bluetooth awakening broadcast; and if the broadcast manufacturer information is matched with the local manufacturer information, the Bluetooth awakening broadcast extracts the broadcast MAC address in the Bluetooth awakening broadcast.
Before comparing the broadcast MAC address with the local MAC address, the broadcast manufacturer information and the local manufacturer information in the broadcast information can be compared, if the broadcast manufacturer information is not matched with the local manufacturer information, the master control chip of the Bluetooth remote controller directly discards the Bluetooth awakening broadcast. The broadcast MAC address in the broadcast information is further extracted only when the broadcast manufacturer information is matched with the local manufacturer information, the condition that excessive computing resources of the main control chip are wasted to extract and compare the broadcast MAC address is avoided, when the manufacturer information is not matched, the Bluetooth awakening broadcast received by the second Bluetooth module of the Bluetooth remote controller is directly abandoned, and the MAC address comparison efficiency is improved.
After the step of detecting whether the pre-stored local wake-up file is empty by the bluetooth remote controller, the method further includes:
step H1, if the local wake-up file is empty, when the second Bluetooth module of the Bluetooth remote controller receives the Bluetooth wake-up broadcast, the Bluetooth remote controller judges whether the signal intensity of the Bluetooth wake-up broadcast is greater than a preset intensity threshold value;
step H2, if the signal intensity of the Bluetooth awakening broadcast is greater than the preset intensity threshold value, when the broadcast manufacturer information and the local manufacturer information in the Bluetooth awakening broadcast are matched, the Bluetooth remote controller stores the broadcast MAC address in the Bluetooth awakening broadcast into a local awakening file to be used as a local MAC address, and Bluetooth pairing between the second Bluetooth module and the display device sending the Bluetooth awakening broadcast is achieved; and the Bluetooth remote controller executes the step of acquiring and identifying the broadcast key instruction of the Bluetooth wakeup broadcast.
When the master control chip of the bluetooth remote controller judges that the local wake-up file is empty, the bluetooth remote controller does not complete bluetooth pairing with any display device currently, and the bluetooth remote controller can perform bluetooth pairing with the display device of the same manufacturer, for example, if the manufacturer of the bluetooth remote controller is a current subscriber, the bluetooth remote controller only needs to perform bluetooth pairing with the display device of the manufacturer of the current subscriber based on comparison between the broadcast manufacturer information and the local manufacturer information.
In addition, after the step of obtaining and identifying the broadcast key command of the bluetooth wakeup broadcast, the method further includes: and if the broadcast key instruction is not a preset startup and shutdown instruction, discarding the broadcast information by the Bluetooth remote controller.
The present application also provides a computer readable storage medium having stored thereon a computer program which, when executed by a processor, implements the steps of the bluetooth remote controller retrieval method as described above.
