Abstract

The invention discloses a Bluetooth transmission device, and the device comprises a slave module which is connected with a first host, wherein the first host transmits first data to the slave module; a broadcasting module which is used for sending second data to a working group in a broadcasting mode, wherein the working group comprises a first host, and the second data is obtained through detection of the detection module; a single chip microcomputer which is connected with the detection module, the slave module and the broadcasting module and used for storing the third data collected by the detection module and transmitting the fourth data to the slave module according to the first data, and transmitting the second data to a broadcasting module, wherein the third data comprises the second data and the fourth data. And the technical effects of continuously sending the broadcast packet to the outside while being connected with the host and improving the data transmission efficiency are achieved.

Description

technical field [0001] The invention relates to the technical field of bluetooth, in particular to a bluetooth transmission device. Background technique [0002] The working mode of a Bluetooth BLE device is usually broadcast mode or slave mode, and the device cannot be connected in broadcast mode. In the slave mode, after the device is connected, broadcast packets cannot be sent. In one-to-many (one slave connected to multiple hosts) scenarios, time-division multiplexing is mostly used, and data access efficiency and timeliness requirements are high. The scene performance is not ideal. Its shortcomings are mainly manifested in: [0003] After the Bluetooth device in the slave mode is connected, only one-to-one data transmission can be realized. In the scene of one-to-many devices, it must be time-division multiplexed, and the real-time performance and device bandwidth are limited. [0004] The broadcast mode Bluetooth device has a fixed beacon packet when it broadcasts d...
