# Set_bluetooth

#### 介绍

用于驱动安装了Armbian/CentOS/ArchLinux系统的cm311-1a/m401a/unt403a/b860av3.2m的蓝牙模块（rtl8761b）

#### 安装教程

终端输入

1.  git clone https://gitee.com/xiayang0521/set_bluetooth.git

2.  cd set_bluetooth

3.  
(1) Armbian下

 apt install bluez gpiod -y 

(2) CentOS下

 yum install bluez -y 

(3) Archlinux下

pacman -Sy bluez bluez-utils libgpiod 

systemctl enable bluetooth.service

systemctl start bluetooth.service

4.  bash set_bt.sh

5.  注意在启动项中使用/boot/dtb/amlogic/meson-g12a-s905l3a-cm311.dtb

6.  reboot

#### set_bt.sh文件说明
#### 在uart_A部分增加bluetooth内容 
cp meson-g12a-s905l3a-cm311.dtb /boot/dtb/amlogic/meson-g12a-s905l3a-cm311.dtb

#### service 增加 ExecStopPost=/usr/bin/env gpioset 0 82=0
cp /lib/systemd/system/bluetooth.service /lib/systemd/system/bluetooth.service_bak

cp bluetooth.service /lib/systemd/system/bluetooth.service

# archlinux下使用 cp bluetooth.service_arch /lib/systemd/system/bluetooth.service

#### 将2M波特率的config文件复制到/lib/firmware/rtl_bt/rtl8761b_config.bin。系统自带的config文件不能用，之前在用户空间操作也有这个问题
cp /lib/firmware/rtl_bt/rtl8761b_config.bin /lib/firmware/rtl_bt/rtl8761b_config.bin_bak
cp rtl8761b_config_2m /lib/firmware/rtl_bt/rtl8761b_config.bin
