Abstract

The invention provides a Bluetooth communication method and system based on a vehicle-mounted terminal, and the method comprises the steps: building Bluetooth communication connection with the vehicle-mounted terminal, and transmitting a data packet to the vehicle-mounted terminal, the data packet comprising a message header, a message body and a message serial number; determining whether the initial field length of the message serial number is greater than a preset standard field length or not through a MTU; if so, segmenting the initial field of the message serial number; and converting the field formats of the message header, the message body and the message serial number into preset standard field format through the MTU, and sending the message header, the message body and the message serial number with converted field formats to the vehicle-mounted terminal. Through the method, the formats of the message header, the message body and the message serial number can be subjected to standardized constraint, so that the message sending time is shortened, the message sending fluency is improved, the automobile response time is shortened, and the user experience is improved.

Description

technical field [0001] The invention relates to the technical field of automobiles, in particular to a Bluetooth communication method and system based on a vehicle-mounted terminal. Background technique [0002] With the advancement of science and technology and the rapid development of productivity, cars have been popularized in people's lives, and have also become one of the indispensable means of transportation for people to travel, which facilitates people's lives. [0003] Existing cars all have bluetooth function after leaving the factory, to increase the interaction between driver or occupant and car. [0004] However, the fluency of information interaction between the existing vehicle-mounted Bluetooth and the mobile terminal is relatively low, which increases the reaction time of the vehicle, thereby reducing user experience. Contents of the invention [0005] Based on this, the purpose of the present invention is to provide a Bluetooth communication method and s...
