Problems solved by technology

However, in the prior art, the smart terminal sends all the data to the smart bracelet through the Bluetooth module, and the smart bracelet saves the data once. The data is still saved, which makes the subsequent upgrade of the smart bracelet according to the received updated firmware fail because the data saved in the smart bracelet is incorrect.

Embodiment Construction

[0064] The following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only some, not all, embodiments of the present invention. Based on the embodiments of the present invention, all other embodiments obtained by persons of ordinary skill in the art without creative efforts fall within the protection scope of the present invention.

[0065] see figure 1 , figure 1 It is a flow chart of Embodiment 1 of a Bluetooth-based data transmission method of the present invention. The method can be applied to an intelligent terminal with a bluetooth module, and the method includes:

[0066] Step S101: the sender divides the data segment to be transmitted into multiple data strips.

[0067] Specifically, when the sender transmits data to the receiver via bluetooth, generally, the receiver receives the tr...

Abstract

A Bluetooth-based data transmission method and device is disclosed. The method comprises the following steps: a sender divides a data segment to be transmitted into a plurality of data bars, sequence numbers are respectively added to the plurality of data bars, and therefore a plurality of data bars having the sequence numbers are obtained.A sequence number M is added to a Nth data bar, the sequence number M is used for signifying ranking of the Nth data bar in k neighboring data bars including the Nth data bar, the sender sends the data bars having the sequence numbers to a receiver, the receivers receives the data bars having the sequence numbers, and whether the sequence of the plurality of data bars having the sequence numbers is consistent with the sequence numbers added to the data bars having the sequence numbers is determined; if yes, the receiver requests the sender to resend the data segment with errors. Through the above method, correctness of the data sequence can be ensured when data is transmitted via Bluetooth.

Description

technical field [0001] The present invention relates to the field of terminals, in particular to a Bluetooth-based data transmission method and device. Background technique [0002] The firmware of the smart bracelet has been fixed in the smart bracelet by the manufacturer when it leaves the factory. After leaving the factory, due to reasons such as bug fixes and firmware upgrades, users need to upgrade the firmware in the smartphone. When the user needs to upgrade the firmware in the smart bracelet, the user can transmit the updated firmware to the smart bracelet through the Bluetooth module in the smart terminal, so that the firmware in the smart bracelet can be upgraded. However, in the prior art, the smart terminal sends all the data to the smart bracelet through the Bluetooth module, and the smart bracelet saves the data once. The data is still saved, which makes the subsequent smart bracelet upgrade according to the received updated firmware, because the data stored ...
