Description
Technical Field
The present invention relates to the field of consumer electronics technologies, and in particular, to a data transmission method, an electronic device, and a storage medium.
Background
With the development of consumer electronics technology, the functions of consumer electronics products are more and more, and some set top boxes on the market support the Findme function. The Findme function means that after the bluetooth remote controller and the set top box are paired, the set top box detects whether a key value signal output by the bluetooth remote controller is received after being powered on, and if not, the Findme function indicates that a user may not find the bluetooth remote controller, and if the user may fall in a certain corner (such as a sofa gap). At this moment, the set top box can be connected with the Bluetooth remote controller through the Bluetooth, then is connected through the Bluetooth, sends a buzzing instruction to the Bluetooth remote controller, and the Bluetooth remote controller will begin buzzing after receiving the buzzing instruction, so as to prompt the user that the user is 'I here'.
However, if the set-top box implements the Findme function, it is required that the bluetooth remote controller cannot be in the deep sleep state, and since the set-top box cannot be connected back to the bluetooth remote controller in the deep sleep state, the set-top box cannot send a buzzer instruction to the bluetooth remote controller, so that the Findme function cannot be implemented.
As shown in fig. 1, in the prior art, a is a broadcast duration for the bluetooth remote controller to transmit an a broadcast packet, and B is a broadcast duration for the bluetooth remote controller to transmit a B broadcast packet. According to the convention bluetooth protocol stack, the bluetooth remote controller must repeatedly send out a broadcast packet every 3.75ms within a complete broadcast duration (for example, a or b), which makes the set-top box only need to scan 3.75ms to receive the broadcast packet sent by the bluetooth remote controller, but at the same time, this also makes one broadcast become a continuous broadcast as a whole, because 3.75ms is almost negligible for one broadcast duration, one broadcast duration is hundreds of milliseconds or seconds, and 30 seconds or even 1 minute, so according to the convention bluetooth protocol stack, the broadcast packet sent out by the bluetooth remote controller can be regarded as a continuous broadcast packet.
For a set top box with a Findme function in a common user home, once the set top box is powered off, in order to realize the Findme function after the set top box is powered on, the bluetooth remote controller is switched from a working mode to a shallow sleep mode, and repeatedly sends a broadcast packet outwards once every 3.75ms, namely sends a continuous broadcast packet outwards, and the bluetooth remote controller consumes power consumption when sending the broadcast packet, namely in a period a and a period b. Since the bluetooth remote controller is in the shallow sleep mode most of the day, the power consumption of the bluetooth remote controller during the shallow sleep mode is often large.

and sending a broadcast packet outwards every other first set time within the set packet sending time, wherein the duration of sending the broadcast packet once is a second set time, and the first set time and the second set time are both smaller than the set packet sending time.

All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.
Referring to fig. 2 and fig. 3, the data transmission method provided in this embodiment is applicable to a first electronic device with a bluetooth communication function in a shallow sleep mode, where the first electronic device has successfully bluetooth paired with a second electronic device with a bluetooth communication function.
As shown in fig. 2, the data transmission method of the present embodiment is applicable to an application scenario, and specifically includes: a first electronic device left in a certain corner by a user is in a shallow sleep mode and continuously sends a broadcast packet outwards; when the second electronic equipment is powered on, the key value signal of the first electronic equipment is not detected, Bluetooth connection is established with the first electronic equipment according to a broadcast packet sent by the first electronic equipment, and a buzzing instruction is sent to the first electronic equipment based on a Bluetooth protocol; and the first electronic equipment starts buzzing vibration according to the buzzing instruction so as to prompt the user that the first electronic equipment is located.
As shown in fig. 3, the data transmission method provided in this embodiment is suitable for a first electronic device with a bluetooth communication function in a shallow sleep mode, where the first electronic device has successfully bluetooth paired with a second electronic device with a bluetooth communication function, and the method specifically includes the following steps:
s110, acquiring the set packet sending time length.
Preferably, the first electronic device is a bluetooth remote controller.
Preferably, the second electronic device is a set-top box with Findme functionality.
Preferably, the second electronic device is a television with Findme function.
In one embodiment, as shown in fig. 1, when the bluetooth remote controller is transmitting a broadcast packet a, the set packet transmission duration is taken as a, where a is the broadcast duration of the bluetooth remote controller transmitting a broadcast packet according to the specification of the bluetooth protocol stack, and similarly, when the bluetooth remote controller is transmitting a broadcast packet B, the set packet transmission duration is taken as B. Therefore, the set packet sending time is a priori information, and the set packet sending times corresponding to different broadcast packets sent by the Bluetooth remote controller according to the Bluetooth protocol stack are all stored in the storage device of the Bluetooth remote controller.
And S120, sending a broadcast packet outwards every other first set time within the set packet sending time, wherein the duration of sending the broadcast packet once is a second set time, and the first set time and the second set time are both smaller than the set packet sending time.
Preferably, the set packet sending time length a is approximately equal to x, x is (n-1) x m + n x p, and n is greater than or equal to 8 and less than or equal to a/8, where a is the set packet sending time length, n is the total number of broadcast packets sent within the set packet sending time length, p is a single packet sending time length for sending one broadcast packet, m is a packet sending interval time length for sending two adjacent broadcast packets, the actual packet sending time length x is the sum of the accumulated packet sending interval time length n x p and the accumulated single packet sending time length (n-1) x m, and the units of a, x, m, and p are milliseconds.
Preferably, the packet sending time length a is set to 300 ms.
In this embodiment, to ensure that the first electronic device and the second electronic device can be connected back to each other with high probability, it is preferable that the actual packet sending time length x is less than r, and r is t/2, where t is a scanning interval of the second electronic device when performing bluetooth scanning, r is a scanning time length of the second electronic device when performing bluetooth scanning, and both the units of r and t are milliseconds.
In one embodiment, the first electronic device is a bluetooth remote controller, the second electronic device is a set top box, and the broadcast packet sent by the first electronic device carries device information of the first electronic device. As shown in fig. 4, when the bluetooth remote controller sends an a broadcast packet, a set packet sending time length a is 300ms, n times of the a broadcast packets are sent outwards within 300ms, the a broadcast packets are sent outwards once every time length m, the single packet sending time length for sending one broadcast packet is p, the accumulated packet sending interval time length is n × p, the accumulated single packet sending time length is (n-1) × m, the actual packet sending time length x is (n-1) × m + n × p, and n is greater than or equal to 8 and less than or equal to a/8, wherein p is generally tens to hundreds of microseconds for a single packet sending time length, that is, p is generally less than 1ms, and the specific value of p is determined by hardware factors such as a main chip, a crystal oscillator, a circuit and the like of the bluetooth remote controller. On one hand, because the Bluetooth remote controller mainly consumes power when sending the broadcast packet in a shallow sleep mode, if the value of n is too large, the frequency of sending the broadcast packet by the Bluetooth remote controller is too high, and the purpose of reducing the power consumption cannot be achieved; on the other hand, the set-top box needs to scan 38 times in 300ms at least according to the minimum scanning frequency specified by the bluetooth protocol, and if the value of n is too small, the frequency of the broadcast packet sent by the bluetooth remote controller is too low, so that the set-top box is difficult to scan the broadcast packet sent by the bluetooth remote controller, and the reconnection speed is slow.
In this embodiment, the set packet sending time length a is 300ms, the single packet sending time length p is preferably 0.1ms, and n is greater than or equal to 8 and less than or equal to 38 because n is an integer. The Bluetooth remote controller sends an A broadcast packet within 300ms, when n is 8, m is (300-0.8)/7 is approximately equal to 42.74ms, namely the Bluetooth remote controller sends the A broadcast packet outwards every 42.74ms within 300ms of the A broadcast packet for 8 times, the actual packet sending time length x of the A broadcast packet is (8-1) x 42.74+8 x 0.1 is 299.98ms, namely a is approximately equal to x, the difference between the packet sending time length a and the actual packet sending time length x is set to be only 0.02ms, and the scanning result of the set top box is not influenced basically; when n is 38, m is (300-0.38)/37 is approximately 8.10ms, namely the bluetooth remote controller sends an a broadcast packet outwards every 8.10ms within 300ms of sending the a broadcast packet for 38 times, the actual packet sending time length x for sending the a broadcast packet is (38-1) × 8.10+38 × 0.1 is 300.08ms, namely a is approximately x, the difference between the set packet sending time length a and the actual packet sending time length x is only 0.08ms, and the scanning result of the set-top box is not influenced basically.
After the bluetooth remote controller finishes sending the a broadcast packet, if the bluetooth remote controller does not successfully reconnect with the set top box, the bluetooth remote controller starts to send the B broadcast packet after a time length z until the bluetooth remote controller reconnects with the set top box, and the process of sending the B broadcast packet can refer to the process of sending the a broadcast packet, which is not described herein again.
In the prior art, the bluetooth remote controller transmits the a broadcast packet according to the bluetooth protocol, and the a broadcast packet needs to be transmitted 80 times within 300ms, that is, the bluetooth remote controller nearly transmits the continuous broadcast packet. In the technical scheme of the embodiment, the Bluetooth remote controller does not comply with the regulation of a Bluetooth protocol, but intermittently sends the A broadcast packet, and only needs to send the A broadcast packet 8-38 times within 300 ms.
It should be noted that, in the technical solution of this embodiment, after the set-top box is connected back, the bluetooth remote controller performs bluetooth communication with the set-top box according to the bluetooth protocol.
In summary, in this embodiment, when the first electronic device is in the shallow sleep mode, the broadcast packet is sent out every first set duration within the set packet sending duration, so that the second electronic device that has been successfully paired can quickly scan the broadcast packet, and the bluetooth connection is quickly reestablished according to the broadcast packet and the first electronic device, thereby realizing the quick reconnection. Because the first electronic device in the shallow sleep mode generates power consumption only when the broadcast packet is sent outwards, the first electronic device intermittently sends the broadcast packet outwards within the set packet sending time, compared with the prior art that the continuous broadcast packet is sent, the frequency of sending the broadcast packet outwards is greatly reduced, and the power consumption of the first electronic device in the shallow sleep mode is effectively reduced on the premise that the first electronic device and the second electronic device can be quickly connected back.
Referring to fig. 5, on the basis of the foregoing embodiment, in this embodiment, preferably, before the step of obtaining the set packet sending duration, the method further includes:
and carrying out Bluetooth pairing with the second electronic equipment.
Therefore, the second electronic equipment can record the equipment information of the first electronic equipment, and the first electronic equipment can be identified to send out the broadcast packet without being interfered by other Bluetooth equipment.
Based on the above optimization, the data sending method provided in this embodiment may specifically include the following steps:
and S210, carrying out Bluetooth pairing with the second electronic equipment.
In one embodiment, the first electronic device is a bluetooth remote control and the second electronic device is a set-top box. Before the set top box is controlled for the first time, the Bluetooth remote controller needs to send a Bluetooth pairing signal to the set top box, and exchanges equipment information with the set top box and stores the equipment information.
S220, acquiring the set packet sending time length.
And S230, sending the broadcast packet outwards every other first set time within the set packet sending time, wherein the duration of sending the broadcast packet is a second set time, and the first set time and the second set time are both smaller than the set packet sending time.
In summary, in this embodiment, the first electronic device and the second electronic device successfully perform bluetooth pairing, and when the first electronic device is in the shallow sleep mode, the broadcast packet is sent out every first set time interval within the set packet sending time interval, so that the second electronic device that has been successfully paired can quickly scan the broadcast packet, and quickly reestablish bluetooth connection with the first electronic device according to the broadcast packet, thereby implementing quick reconnection. Because the first electronic device in the shallow sleep mode generates power consumption only when the broadcast packet is sent outwards, the first electronic device intermittently sends the broadcast packet outwards within the set packet sending time, compared with the prior art that the continuous broadcast packet is sent, the frequency of sending the broadcast packet outwards is greatly reduced, and the power consumption of the first electronic device in the shallow sleep mode is effectively reduced on the premise that the first electronic device and the second electronic device can be quickly connected back.
