Referring to fig. 4, based on the first embodiment of the method for upgrading software of a bluetooth speaker of the present invention, and the second embodiment of the method for upgrading software of a bluetooth speaker of the present invention, the step S30 of sending the upgrade software to the bluetooth speaker by using a bluetooth broadcast mode by the intelligent terminal includes:
step S31, the intelligent terminal stores the upgrade software into a plurality of broadcast packets with a preset sending sequence;
step S32, the intelligent terminal sends the broadcast packets to the Bluetooth loudspeaker in a Bluetooth broadcast mode according to a preset sending sequence;
and step S33, when the intelligent terminal receives the message which is sent by the Bluetooth loudspeaker and completes receiving, the intelligent terminal finishes sending the broadcast packet.
The files are transmitted based on the Bluetooth broadcast communication protocol, a form of broadcast packets needs to be adopted, and the size of each broadcast packet should be set according to the Bluetooth broadcast communication protocol to ensure that each broadcast packet can be transmitted smoothly.
In this embodiment, 10 bytes of data are taken from the upgrade software each time to form a broadcast packet, and of course, the data of the last broadcast packet may be less than 10 bytes. A transmission order is preset for each broadcast packet so that the respective broadcast packets are transmitted in order. Of course, the size of each broadcast packet may be arbitrarily set within the allowable range of the bluetooth broadcast communication protocol, and is not further limited herein.
And in order to identify the transmission end point of the upgrade software, adding an ending identifier which can be identified by the Bluetooth loudspeaker into the last broadcast packet, and when the Bluetooth loudspeaker receives the last broadcast packet, feeding back the message of completing reception to the intelligent terminal by identifying the ending identifier so that the intelligent terminal identifies that the transmission process of the upgrade software is ended. Meanwhile, the file receiving state of each Bluetooth loudspeaker can be displayed on the control interface, and/or the state of a broadcast packet sent to the Bluetooth loudspeaker by the intelligent terminal.
Based on the second embodiment of the software upgrading method for a bluetooth speaker of the present invention, the third embodiment of the software upgrading method for a bluetooth speaker of the present invention, between the step S31 and the step S32, further includes:
step S34 (not shown), the intelligent terminal adds a transmission sequence identifier to each broadcast packet;
referring to fig. 5, the step S32 includes:
step S32a, the intelligent terminal sends the broadcast packet of the current sending sequence to the Bluetooth loudspeaker in a Bluetooth broadcast mode according to a preset sending sequence, and detects a broadcast packet receiving identifier preset in the Bluetooth loudspeaker, wherein the receiving identifier has a preset initial value, and after the Bluetooth loudspeaker successfully stores the broadcast packet of the current sending sequence, the receiving identifier is correspondingly replaced by the sending sequence identifier of the broadcast packet of the current sending sequence;
step S32b, the intelligent terminal receives a first message that the receiving of the broadcast packets in the current sending sequence is finished and returns to the intelligent terminal after the broadcast packets in the current sending sequence are successfully stored when the receiving identification of the Bluetooth speaker is equal to the sending sequence identification of the broadcast packets in the previous sending sequence;
step S32c, after receiving the first message, the intelligent terminal sends the broadcast packets in the next sending sequence to the bluetooth speaker in a bluetooth broadcasting manner according to a preset sending sequence.
And adding a sending sequence identifier for each broadcast packet prestored in the intelligent terminal, and presetting a receiving identifier of the broadcast packet in the Bluetooth loudspeaker. In this embodiment, the transmission sequence identifier is marked by an index, for example, the index of the first transmission sequence broadcast packet is 1, the index of the second transmission sequence broadcast packet is 2, and the index of the nth transmission sequence broadcast packet is n, where n is a positive integer. The sending sequence identifier is not limited to this, as long as the sending sequence can be indicated.
The receiving identifier has a preset initial value, and the receiving identifier is also marked by an index. In this embodiment, the initial value of the receiving identifier is 0.
When the receiving identifier in the bluetooth speaker is equal to the transmitting sequence identifier of the broadcast packet in the previous transmitting sequence, indicating that the broadcast packet in the previous transmitting sequence is already stored in the bluetooth speaker, at this time, the broadcast packet in the current transmitting sequence may be stored in the bluetooth speaker.
For example, when a broadcast packet with a current transmission order of 5 is transmitted to the bluetooth speaker, if it is detected that the reception identifier index in the bluetooth speaker is 4, it indicates that a broadcast packet with a previous transmission order (i.e., a broadcast packet with a fourth transmission order) has been stored in the bluetooth speaker, at this time, the broadcast packet with the transmission order of 5 is stored in the bluetooth speaker, and after the bluetooth speaker successfully stores the broadcast packet with the current transmission order, the reception identifier is replaced with the transmission order identifier of the broadcast packet with the current transmission order, for example, when the bluetooth speaker successfully stores the broadcast packet with the current transmission order of 5 and the transmission order identifier of 5, the reception identifier index is replaced with 5.
The first packet may be an acknowledgement packet whose index is a current sending sequence value, for example, when the current sending sequence is 1, the bluetooth speaker sends the acknowledgement packet whose index is 1 to the intelligent terminal after successfully receiving the broadcast packet in the first sending sequence.
Referring to fig. 6, based on the third embodiment of the software upgrading method for a bluetooth speaker of the present invention, the fourth embodiment of the software upgrading method for a bluetooth speaker of the present invention further includes, after step S32 a:
step S32d, the intelligent terminal receives a second message of an error sent by the Bluetooth speaker to the broadcast packet in the current sending sequence returned by the intelligent terminal when the receiving identifier is not equal to the sending sequence identifier of the broadcast packet in the previous sending sequence;
step S32e, after receiving the second message, the intelligent terminal sends the broadcast packets in the previous sending sequence to the bluetooth speaker in a bluetooth broadcasting manner.
When the receiving identifier in the bluetooth speaker is not equal to the transmitting sequence identifier of the broadcast packet in the previous transmitting sequence, it indicates that the broadcast packet in the previous transmitting sequence is not stored in the bluetooth speaker, that is, the broadcast packet in the previous transmitting sequence is lost in the transmitting process, at this time, it is necessary to return the broadcast packet in the current transmitting sequence to the intelligent terminal to transmit an erroneous second message, so that the intelligent terminal can re-transmit the broadcast packet in the previous transmitting sequence to the bluetooth speaker in a bluetooth broadcasting manner according to the second message.
For example, when a broadcast packet with a current transmission order of 5 is transmitted to the bluetooth speaker, if it is detected that the reception identifier index in the bluetooth speaker is 3, it indicates that a broadcast packet with a previous transmission order (i.e., a broadcast packet with a fourth transmission order) is not stored in the bluetooth speaker, and at this time, the bluetooth speaker may transmit a second packet to the smart terminal instead of receiving the broadcast packet with the current transmission order.
The second packet may be an error packet with a transmission sequence identifier of a previous transmission sequence value, for example, when the current transmission sequence is 2, and when the reception identifier in the bluetooth speaker is not equal to the transmission sequence identifier (index is 1) of the broadcast packet in the previous transmission sequence (broadcast packet in the first transmission sequence), the bluetooth speaker transmits the error packet with index being 1 to the smart terminal, so as to indicate that the first broadcast packet is not successfully received.
And the intelligent terminal sends a broadcast packet which is consistent with the sending sequence identifier in the second message to the Bluetooth loudspeaker based on the sending sequence identifier in the second message.
Based on the third embodiment or the fourth embodiment of the software upgrading method for a bluetooth speaker of the present invention, in the fifth embodiment of the software upgrading method for a bluetooth speaker of the present invention, between the step S32a and the step S32c, the method further includes:
step S32f (not shown), the intelligent terminal receives the first message that the receiving of the broadcast packet in the current sending sequence is completed, which is returned to the intelligent terminal after the broadcast packet in the current sending sequence is successfully stored when the receiving identifier of the bluetooth speaker is equal to the initial value.
Presetting an initial value for the receiving identifier, and when the receiving identifier is detected to be the initial value, the bluetooth speaker needs to receive a broadcast packet in a first sending sequence, wherein the index of the broadcast packet is 1. And storing the broadcast packets in the current transmission sequence (the broadcast packets in the first transmission sequence) in the bluetooth speaker, and correspondingly replacing the receiving identifier index with 1 to complete the reception of the first broadcast packet.
Further, when the receiving identifier in the bluetooth speaker is not equal to the transmitting sequence identifier of the broadcast packet in the previous transmitting sequence, it may be further determined whether the transmitting sequence of the broadcast packet in the current transmitting sequence is the first sequence;
when the sending sequence of the broadcast packets in the current sending sequence is a first sequence, storing the broadcast packets in the current sending sequence in the Bluetooth loudspeaker, and returning a first message that the receiving of the broadcast packets in the current sending sequence is finished to the intelligent terminal;
when the sending sequence of the broadcast packets in the current sending sequence is not the first sequence, returning a second message with an error in sending of the broadcast packets in the current sending sequence to the intelligent terminal;
and after receiving the second message, retransmitting the broadcast packets in the previous transmission sequence to the Bluetooth loudspeaker in a Bluetooth broadcast mode.

For example, when a broadcast packet with a current transmission order of 5 is transmitted to the bluetooth speaker, if it is detected that the reception identifier index in the bluetooth speaker is 4, it indicates that a broadcast packet with a previous transmission order (i.e., a broadcast packet with a fourth transmission order) has been stored in the bluetooth speaker, at this time, the broadcast packet with the transmission order of 5 is stored in the bluetooth speaker, and after the bluetooth speaker successfully stores the broadcast packet with the current transmission order, the reception identifier is replaced with the transmission order identifier of the broadcast packet with the current transmission order, for example, when the bluetooth speaker successfully stores the broadcast packet with the current transmission order of 5 and the transmission order identifier of 5, the reception identifier index is replaced with 5.
The first packet may be an acknowledgement packet whose index is a current sending sequence value, for example, when the current sending sequence is 1, the bluetooth speaker sends the acknowledgement packet whose index is 1 to the intelligent terminal after successfully receiving the broadcast packet in the first sending sequence.
Referring to fig. 10, based on the third embodiment of the intelligent terminal of the present invention, in the fourth embodiment of the intelligent terminal of the present invention, the sending unit 32 further includes:
a fourth subunit 32d, configured to receive, when the receiving identifier is not equal to the sending sequence identifier of the broadcast packet in the previous sending sequence, the second packet that is returned by the bluetooth speaker and is in error in sending the broadcast packet in the current sending sequence to the intelligent terminal;
and a fifth sub-unit 32e, configured to send the broadcast packets in the previous sending sequence to the bluetooth speaker in a bluetooth broadcast manner after receiving the second message.
When the receiving identifier in the bluetooth speaker is not equal to the transmitting sequence identifier of the broadcast packet in the previous transmitting sequence, it indicates that the broadcast packet in the previous transmitting sequence is not stored in the bluetooth speaker, that is, the broadcast packet in the previous transmitting sequence is lost in the transmitting process, at this time, it is necessary to return the broadcast packet in the current transmitting sequence to the intelligent terminal to transmit an erroneous second message, so that the intelligent terminal can re-transmit the broadcast packet in the previous transmitting sequence to the bluetooth speaker in a bluetooth broadcasting manner according to the second message.
For example, when a broadcast packet with a current transmission order of 5 is transmitted to the bluetooth speaker, if it is detected that the reception identifier index in the bluetooth speaker is 3, it indicates that a broadcast packet with a previous transmission order (i.e., a broadcast packet with a fourth transmission order) is not stored in the bluetooth speaker, and at this time, the bluetooth speaker may transmit a second packet to the smart terminal instead of receiving the broadcast packet with the current transmission order.
The second packet may be an error packet with a transmission sequence identifier of a previous transmission sequence value, for example, when the current transmission sequence is 2, and when the reception identifier in the bluetooth speaker is not equal to the transmission sequence identifier (index is 1) of the broadcast packet in the previous transmission sequence (broadcast packet in the first transmission sequence), the bluetooth speaker transmits the error packet with index being 1 to the smart terminal, so as to indicate that the first broadcast packet is not successfully received.
And the intelligent terminal sends a broadcast packet which is consistent with the sending sequence identifier in the second message to the Bluetooth loudspeaker based on the sending sequence identifier in the second message.
Based on the third embodiment or the fourth embodiment of the intelligent terminal of the present invention, in a fifth embodiment of the intelligent terminal of the present invention, the sending unit 32 further includes:
a sixth subunit 32f (not shown), configured to receive the first packet that is returned to the intelligent terminal after the bluetooth speaker successfully stores the broadcast in the current sending sequence when the receiving identifier is equal to the initial value, and that is obtained after the receiving of the broadcast packet in the current sending sequence is completed.
Presetting an initial value for the receiving identifier, and when the receiving identifier is detected to be the initial value, the bluetooth speaker needs to receive a broadcast packet in a first sending sequence, wherein the index of the broadcast packet is 1. And storing the broadcast packets in the current transmission sequence (the broadcast packets in the first transmission sequence) in the bluetooth speaker, and correspondingly replacing the receiving identifier index with 1 to complete the reception of the first broadcast packet.
Further, when the receiving identifier in the bluetooth speaker is not equal to the transmitting sequence identifier of the broadcast packet in the previous transmitting sequence, it may be further determined whether the transmitting sequence of the broadcast packet in the current transmitting sequence is the first sequence;
when the sending sequence of the broadcast packets in the current sending sequence is a first sequence, storing the broadcast packets in the current sending sequence in the Bluetooth loudspeaker, and returning a first message that the receiving of the broadcast packets in the current sending sequence is finished to the intelligent terminal;
when the sending sequence of the broadcast packets in the current sending sequence is not the first sequence, returning a second message with an error in sending of the broadcast packets in the current sending sequence to the intelligent terminal;
and after receiving the second message, retransmitting the broadcast packets in the previous transmission sequence to the Bluetooth loudspeaker in a Bluetooth broadcast mode.
The above description is only a preferred embodiment of the present invention, and not intended to limit the scope of the present invention, and all modifications of equivalent structures and equivalent processes, which are made by using the contents of the present specification and the accompanying drawings, or directly or indirectly applied to other related technical fields, are included in the scope of the present invention.
