Embodiment Construction

[0017] 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.

[0018] refer to figure 1 A method for confirming the connection of fast small amount of data transmission based on BLE, comprising the following steps:

[0019] S1: The sending device is usually in a low power standby state. The passive receiving end is usually in the broadcast packet scanning state. When the active sender needs to send data, it first broadcasts the BLE broadcast data packet to the air. The broadcast data packet includes the address of the target device (passive receiver) or other identification data and a small amount of data to be transmitted; the target address and the data to be transmitted can be original text or cipher text, and if cipher tex...

Abstract

The invention discloses a connection and reverse broadcast confirmation method for rapid and small amount of data transmission based on BLE, and the method comprises the following steps: S1, carrying a small amount of data required to be transmitted in a BLE broadcast packet, and transmitting the data in a plaintext or ciphertext manner; S2, for a connection method and a data connection method, using a connection request as communication confirmation, and if data transmission is completed, cutting off connection immediately; and S3, for a two-way broadcast data connection method, carrying out communication confirmation by using a method of switching a state and broadcasting a BLE broadcast data packet reversely. Secondary development is carried out on the basis of a Bluetooth 4.0 BLE protocol, a connection transmission method and a reverse broadcast transmission method are designed, the connection transmission method and the reverse broadcast transmission method are in the same type of data transmission mode, but the data interaction modes of the connection transmission method and the reverse broadcast transmission method are slightly different, reliable transmission of a small amount of data between devices within extremely short time can be achieved, data transmission delay can be well controlled, and a relatively low occupancy rate of the air bandwidth is maintained.

Description

technical field [0001] The invention relates to the technical field of data communication, in particular to a connection and reverse broadcast confirmation method for fast small amount of data transmission based on BLE. Background technique [0002] With the development of Bluetooth technology today, it has spread to all smart phones. In smart home, Internet of Things and other fields, it is often necessary to transmit a small amount of data quickly, while data transmission needs to maintain high reliability. [0003] The conventional Bluetooth data communication method requires two Bluetooth devices to establish a connection and set a dedicated data channel. Then transmit data through the newly established data channel. This method requires a connection process with many steps, so the first communication delay is relatively large. Because there are many steps, the corresponding energy consumption will be relatively large. For a single Bluetooth device, the number of dev...
