 一.蓝牙HC-05简介

(主要为AT模式介绍)

1.接线要点:

(六个引脚中左右两侧的两个不用连接)

        TX - RX          RX - TX         GND - GND       VCC - VCC(5V)

2.AT模式:

    进入方法:

使用CH340串口工具链接HC-05及电脑USB端(提前下好CH340驱动)

按下HC-05正面黑色小按键的同时插入电脑USB端,待上电后松开按键,观察到HC-05上灯不在快速闪烁,而是隔一到两秒秒闪烁一次时即为成功进入AT模式。

    使用串口工具:

如ATK_XCOM

(我将打包好放在文末的百度网盘中)

切记:设置波特率为38400(此波特率为AT模式必需的),

停止位:1       数据位:8       校验位:None(均为默认值),

随后点击打开串口

     AT常用指令:

查询蓝牙名字             AT+NAME?  

修改蓝牙名字             AT+NAME=你想修改成的名字

查询蓝牙密码             AT+PSWD?

修改蓝牙密码             AT+PSWD=你想修改成的密码

其余AT模式指令与本文最终目的无关,若想进一步学习,自行搜索即可

    关于串口的 CubeMX的配置:

                        

二.单片机与手机之间的蓝牙通信

     1.蓝牙APP

     见文末百度网盘链接中,下载在手机上即可

3.OLED屏幕显示函数

源代码自江科大0.96寸四针脚软件模拟I2C的屏幕显示,原本是标准库,我将其改写为HAL库函数

为了省去麻烦,你可以直接将连接OLED屏幕的SCL引脚,SDA引脚的单片机的两个IO口,在CubeMX中改名为SCL4,SDA4。(因为是模拟I2C,因此任意IO口均可)

分为四个部分OLED4.c         OLED4.h         OLED_Data4.c         OLED_Data4.h

三.两个单片机之间的蓝牙通信

特别注意:使用单片机之间蓝牙通信时,要关掉已经连过蓝牙的手机设备,防止手机抢主机或从机

    1.AT模式修改主从模式

查询主从状态             AT+ROLE?

修改主从状态             AT+ROLE=1设为主机,AT+ROLE=0设为从机

获取蓝牙地址码          AT+ADDR?

 查询绑定从机的地址  AT+BIND?

设置绑定从机的地址    AT+BIND=从机地址(由AT+ADDR?查出来的)

额外需要注意的是 绑定从机地址时,要把地址中的冒号均改为逗号

如   98D3:51:F6852F  改成   98D3,51,F6852F

另外主机与从机密码需一致

自此两个蓝牙就完成了绑定

绑定期间蓝牙不返回消息,上电按着按键重连即可

2.两个单片机之间通信代码部分

CubeMX配置主从机时,要保证两者波特率相同,一般均为9600,其他全部一致

1.主机(用于发送测试数据)

4.预期现象及检验

主机发送整型数字1,从机接收并返回接收到的数据1,

最终两个单片机OLED屏幕上应该都显示0001

经检验现象正确。
