• 蓝牙的使用

  1. 如果使用 Radxa 无线 A8 模块，必须添加以下黑名单才能使 BT 正常工作

  root@rock-4se:/home/radxa# cat /etc/modprobe.d/blacklist.conf blacklist
  pgdrv blacklist btusb blacklist btrtl blacklist btbcm blacklist btintel
  root@rock-4se:~# reboot

  2. Radxa APT 包括用于Broadcom无线模块的broadcom-wifibt-firmware软件包和用于Intel无线模块的intel-wifibt-firmware软件包。需要下载相应的软件包

  root@rock-4se:/home/radxa# apt-get update -y root@rock-4se
  :/home/radxa# apt-get install -y broadcom-wifibt-firmware intel-wifibt-firmware

  3. 测试蓝牙模块的状态并检查蓝牙设备

  root@rock-4se:/home/radxa# systemctl status bluetooth

  4. 运行蓝牙设备

  root@rock-4se:/home/radxa# systemctl start bluetooth

  5. 检测蓝牙设备

  root@rock-4se:/home/radxa# hciconfig hci0: Type: Primary Bus: UART BD
  Address: 10:2C:6B:49:D5:53 ACL MTU: 1021:8 SCO MTU: 64:1 UP RUNNING RX
  bytes:850 acl:0 sco:0 events:58 errors:0 TX bytes:2814 acl:0 sco:0
  commands:58 errors:0

  6. 测试：连接蓝牙音箱，首先安装 pulseaudio

  root@rock-4se:/home/radxa# apt-get install -y
  pulseaudio-module-bluetooth pulseaudio

  7. 运行 pulseaudio

  root@rock-4se:/home/radxa# pulseaudio --start

  8. 使用 pulseaudio 连接

  root@rock-4se:/home/radxa# bluetoothctl [bluetooth]# default-agent
  [bluetooth]# power on [bluetooth]# scan on [bluetooth]# trust
  41:42:1A:8D:A9:65 #BT-280 [bluetooth]# pair 41:42:1A:8D:A9:65 [bluetooth]#
  connect 41:42:1A:8D:A9:65
