Embodiment

[0027] The embodiment of the present invention realizes the method for AC power-on Bluetooth power-on, comprising the following steps:

[0028] Step 1. The uboot of the main chip is powered on and started. The uboot guides the main chip to complete the system initialization and the preset work of related interfaces. Among them, uboot refers to the usb port program of the main chip;

[0029] Step 2, the main chip loads the usb driver, and detects each usb port, and creates a device node after detecting the bluetooth device;

[0030] Step 3, communicate between the main chip and the Bluetooth device, and complete the matching of the usb transmission mode and the Bluetooth firmware data format;

[0031] Step 4. The uboot of the main chip loads the Bluetooth firmware into the Bluetooth device through the USB bus, and the Bluetooth device enters the BLE Scan mode;

[0032] Step 5. In the BLE Scan mode, the bluetooth device performs periodic air package retrieval in the common broa...

Abstract

The invention relates to a Bluetooth technology. The invention solves the problems that currently, in the alternating current power-on startup process, startup is carried out by means of an infrared remote controller, so an infrared receiving system and the infrared remote controller need to be configured, or importing is carried out by placing Bluetooth firmware into special flash, so that a system architecture is complex. The invention discloses a method for implementing alternating current power-on Bluetooth startup. The technical scheme of the invention can be summarized as that: the Bluetooth firmware is directly loaded to Bluetooth equipment by a main chip uboot, and then the Bluetooth equipment is controlled by Bluetooth remote controller to send a bootloader startup command to the main chip so as to enable the main chip to be in an active state, thereby implementing startup. The method has the beneficial effects that the system architecture is simple; and the method is convenient to start up and is applicable to a device with a Bluetooth function.

Description

technical field [0001] The invention relates to the bluetooth technology, in particular to the bluetooth start-up technology. Background technique [0002] The existing AC power-on methods are: 1. After AC power-on, use the infrared remote control to start up. This method needs to configure an infrared receiving system and an infrared remote control; 2. Put the Bluetooth firmware into a special flash for import. The way the system structure is complex. Contents of the invention [0003] The purpose of the present invention is to propose a method for realizing AC power-on Bluetooth startup, which solves the need to configure an infrared receiving system and an infrared remote controller with the help of an infrared remote controller during the current AC power-on startup process, or by placing the Bluetooth firmware in a dedicated Importing in flash, the problem of complex system architecture. [0004] The present invention solves its technical problem, adopts the technic...
