Problems solved by technology

[0002] As a global short-distance wireless communication technology, Bluetooth technology provides short-distance data transmission means, and has great advantages in low cost, low power consumption, relatively high speed, etc., so it is widely used in various short-distance Data transmission, such as short-distance transmission of pictures, text, audio and video, etc.; but because Bluetooth uses frequency hopping technology, it usually takes about 10 seconds to have the same scanning frequency and search frequency. Therefore, the device is found The process is time-consuming, resulting in a longer time required to complete the connection

Abstract

The invention discloses a data transmission method comprising the steps that sound wave signals are received and the sound wave signals are demodulated so that demodulation information is acquired, and the demodulation information includes the bluetooth address of target bluetooth equipment; a bluetooth transmission link with the target bluetooth equipment is established according to the bluetooth address; and target data transmitted by the target bluetooth equipment are received through the bluetooth transmission link. Correspondingly, the invention also discloses a data transmission device. With application of the data transmission method and device, discovery time of the bluetooth equipment can be shortened so that time required for bluetooth connection can be shortened.
