前言

开发板集成了 wifi&bt 模块（AP6275S），测试该模块的 bluetooth 蓝牙功能。

原理图wifi&bt模块

软件平台：Ubuntu 20.04.4 LTS
硬件平台： NXP 公司的 i.MX6ULL

一、bluez5.47编译

编译之前需要交叉编译工具链，及环境配置，路径根据自己环境配置

mkdir pkgconfig
cp -r /home/cyzhangep/workspace/6ull_41/dbus_zzy1/dbus-1.6.16/install_us/lib/pkgconfig/dbus-1.pc ./pkgconfig
cp -r /home/cyzhangep/workspace/6ull_41/dbus_zzy1/expat-2.2.7/install_us/lib/pkgconfig/expat.pc ./pkgconfig

make LIBS=-lncurses
make install DESTDIR=/home/cyzhangep/workspace/6ull_41/dbus_zzy1/bluez-5.47/install_us

编译结束，工具及库在相应的install_us目录下，拷贝到板卡

二、使用步骤

1.测试脚本

如下：

#!/bin/sh
echo "statr config bt......"

export PATH=/sbin/:$PATH
export DBUS_SESSION_BUS_ADDRESS=unix:path=/var/run/dbus/system_bus_socket
brcm_patchram_plus -d --enable_hci --no2bytes --tosleep 115200 --baudrate 115200 --patchram /lib/firmware/BCM4362A2_001.003.006.1100.1189.hcd --bd_addr 11:22:33:44:55:66 /dev/ttymxc2 &

groupadd -g 3065 messagebus -p x
useradd  -d '/var/lib/dbus/' -g messagebus  -s /bin/false messagebus -p x
groupadd lp -p x
useradd  -d '/var/spool/lpd' -g lp  -s /bin/sh lp -p x
dbus-uuidgen --ensure
dbus-daemon --system --print-pid --print-address
mkdir -p  /home/
# eval dbus-launch --sh-syntax
export $(dbus-launch)
/libexec/bluetooth/bluetoothd -n -d &

2.bluetoothctl工具

bluetoothctl  //打开 bluez 蓝牙工具

power on  //启动蓝牙设备

pairable on //设置为配对模式

discoverable on  //设置为可发现模式

agent on  //启动代理

default-agent  //设置当前代理为默认
//打开手机配对
