Method and system of communicating via bluetooth serial port

Abstract

The invention is used in the source device and destination device having blue tooth series port. The source device has at least one source series port using module, and the destination device has a destination series port using module corresponding to the one in the source device. The method includes: firstly an identifier is allocated to each source series port using module, and a coincidence relation table is built between the identifier and the destination series port using module; when the destination device receives the information showing the local blue tooth series port is at connection state, it gets the identifier allocated by source series port using module; in term of the coincidence relation table, starting up the destination series port using module corresponding to the source series port using module; finally the blue tooth series port is opened to make communication.

Description

technical field [0001] The invention relates to the bluetooth wireless communication technology, in particular to the serial port communication technology in the bluetooth technology. Background technique [0002] SPP (Serial Port Profile, serial interface application framework,) is an important part of the Bluetooth technical specification. The source device and the target device at both ends of the Bluetooth serial port are connected wirelessly through Bluetooth signals. The Bluetooth software at the bottom of the SPP is responsible for the establishment and disconnection of the Bluetooth serial port connection, and the Bluetooth serial port monitoring unit inside the target device communicates with the bottom Bluetooth software to learn the current connection status of the Bluetooth serial port. [0003] At present, the method of communicating through the Bluetooth serial port is: the user starts the serial port use unit of the target device, and then the serial port use ...

AI Technical Summary

Problems solved by technology

[0004] As mentioned above, in the prior art, before the Bluetooth communication between the source device and the target device, the serial port usage unit of the target device must be started in advance, because the start-up process in the prior art must be realized by manual intervention by the user, causing the user's operation complicated process

Furthermore, since the same Bluetooth serial port only allows one serial port user unit to use the Bluetooth serial port at the same time, when multiple serial port use units share the same Bluetooth serial port, if you want to switch to another serial port use unit, you first need to close the Use the serial port usage unit of this serial port, and then start another serial port usage unit. At this time, the mode of manually starting the serial port usage unit in the prior art is more complicated, which reduces the user experience.
