Embodiment Construction

[0022] The present invention will be further described below in conjunction with the accompanying drawings.

[0023] Such as figure 1 As shown, the Bluetooth car hands-free device adopts CSR Bluetooth single chip, and its parameter download is realized through SPI, and the function of parallel port to SPI is completed through the Bluetooth SPI programmer. The connection signals between the Bluetooth SPI programmer and the Bluetooth car hands-free device include: GND, MOSI, MISO, CSB, CLK, VCC-3.3. Among them, GND and VCC-3.3 are power lines, GND is "ground", and VCC-3.3 is 3.3V voltage. CLK is the serial clock line, MISO is the master input / slave output data line, MOSI is the master output / slave input data line, and CSB is an active low slave select line.

[0024] When in use, connect the Bluetooth SPI programmer to the Bluetooth car hands-free device, the Bluetooth car hands-free device supplies power to the Bluetooth SPI programmer, connect the Bluetooth SPI programmer to ...

Abstract

The invention relates to a downloading method of key parameter of a bluetooth vehicle-mounted hand free device, comprising the following steps: connecting a bluetooth SPI HT-writer with a bluetooth vehicle-mounted hand free device; setting an echo cancellation algorithm serial number, i.e. a CVC serial number; inputting a substrate number ID; inputting a bluetooth address; building SPI connection; successively programming the bluetooth address, the CVC serial number and the substrate number; carrying out warm reset; reading back and checking the substrate number and the bluetooth address. After succeeding in programming, the invention automatically records the substrate number, the bluetooth address, the CVC serial number, write time and the like on programming in the programming log, which is favourable for production line managers to effectively and quickly master the production situation of the bluetooth vehicle-mounted hand free device every day. In addition, the adjustment is conducted whether the parameter of the programming before carrying out programming appears in the programming log; if yes, the parameter is downloaded again to ensure that the product has the unique bluetooth address in the world.

Description

technical field [0001] The invention relates to a bluetooth technology, in particular to a method for downloading key parameters of a bluetooth vehicle-mounted hands-free device. Background technique [0002] At present, as more and more car owners begin to pay attention to the safety and convenience of driving calls, the Bluetooth hands-free devices in the car are gradually becoming popular. With the Bluetooth car hands-free device, you can use the Bluetooth hands-free function to answer the call when you are talking in the car, so that the safety of driving is guaranteed, and it can avoid irreversible damage to the ear caused by the earphone, and the radiation damage of the mobile phone will be greatly reduced at the same time. reduce. [0003] As a Bluetooth product, the Bluetooth car hands-free device must have a one-to-one correspondence with the product and a globally unique Bluetooth address. Each product also has a unique board number, and the board number and the B...
