Abstract

The invention discloses a data transmission method based on low-power-consumption Bluetooth. The method comprises the following steps: receiving a low-power-consumption Bluetooth broadcast data packet sent by broadcaster equipment; and for the low-power-consumption Bluetooth broadcast data packet, sending scanning request data to the broadcaster equipment, wherein the scanning request data is used for indicating that the broadcaster equipment contains data required by the scanner equipment in a scanning response packet sent to the scanner equipment. By the adoption of the method, the problems that in the prior art, time expenditure and power consumption expenditure are large when broadcaster equipment and scanner equipment conduct two-way communication are solved.

Description

technical field [0001] This application relates to the field of computer technology, specifically two data transmission methods based on low-power Bluetooth. This application also relates to a data transmission device based on low-power Bluetooth, as well as an electronic device and a storage device. This application It also relates to two data transmission methods, and the present application also relates to a method for acquiring environmental data. Background technique [0002] As we all know, BLE (Bluetooth Low Energy) broadcasting is a one-way information publishing mode, that is, the advertiser device (Advertiser) places the information to be published in the broadcast data, and then sends the entire broadcast data packet. The scanner device (Scanner, that is, the device in scanning mode) can scan the broadcast data packet, if the broadcast type of the broadcast data packet is Connectable Undirected Advertising ADV_IND or Scannable Undirected Advertising (Scannable Und...
