A method and device for improving Bluetooth compatibility between POS machine and mobile terminal

Abstract

The invention discloses a method for improving the compatibility between a POS machine and a mobile terminal Bluetooth part. The method includes the steps that an address type of a Bluetooth part 4.0 of the POS machine is set to be a public type, and the address of the Bluetooth part 4.0 accordingly follows an address of a Bluetooth part 2.1; an inquiring scanning type of the Bluetooth part 2.1 of the POS machine is set to be interlaced, the interval of an inquiring scanning window of the Bluetooth part 2.1 of the POS machine for inquiring scanning operation is accordingly shortened; calling scanning operation is carried out by shortening the interval of a calling scanning window of the POS machine; the discoverability of the POS machine and the connecting performance between the mobile terminal and the POS machine are improved. The invention further discloses a device for improving the compatibility between the POS machine and the mobile terminal Bluetooth part.

Description

technical field [0001] The invention relates to the field of bluetooth communication, in particular to a method and a device for improving the bluetooth compatibility between a POS machine and a mobile terminal. Background technique [0002] In the traditional electronic financial payment industry, financial POS (point of sale) machines play a pivotal role. However, with the development of mobile e-commerce, mobile phone consumption has gradually become an important means of payment for people's current consumption. More and more POS machines Use Bluetooth to communicate with the user's mobile phone. However, the ensuing problem is the compatibility of Bluetooth communication between POS machines and mobile phones. The development of Bluetooth protocol has gradually transitioned from Bluetooth 2.1 used by most devices to low-power Bluetooth 4.0. The two camps: android and ios mainly use the Bluetooth of these two protocols as their own Bluetooth tools, so the Bluetooth of t...

AI Technical Summary

Problems solved by technology

[0006] 1) The discoverability is poor. The query scan type of the Bluetooth 2.1 device of the dual-mode module defaults to standard, and the query scan performance of this type is poor.

At the same time, the Bluetooth 4.0 device address of the dual-mode module is set to the random type. In this case, the Bluetooth 2.1 address is separated from the Bluetooth 4.0 address. The device found by the user using the mobile phone is two devices. If the user uses the Bluetooth 2.1 function of the mobile phone, then search You can only wait for Bluetooth 2.1 devices to be found, and the discoverability of Bluetooth 2.1 devices is weaker than the broadcast mode of Bluetooth 4.0 devices, so this solution will also cause Bluetooth 2.1 discoverability of dual-mode devices to be very poor

[0007] 2) Poor connectivity. The connection of dual-mode devices is divided into RFCOMM connection of Bluetooth 2.1 and GATT connection of Bluetooth 4.0. Unable to connect to the upper layer
