Bluetooth 蓝牙5.0 ubuntu 18.04

目前，ubuntn对蓝牙5.0支持的比较差。

市面上暂时没有免驱动的蓝牙5.0适配器。

我用的蓝牙适配器是 ORICO BTA608，官网上支持win7-win10。

因为，ORICO BTA608使用的是TRL8761B芯片，所以我手动安装驱动。

我的内核做了一次升级（后来发现有可能不用升级）

参考这篇博客即可

ubuntu 更新内核HWE_billbliss的专栏-CSDN博客Ubuntu 20.04 LTS - Focalsudo apt-get install --install-recommends linux-generic-hwe-20.04Ubuntu 18.04 LTS - Bionic# DESKTOPsudo apt-get install --install-recommends linux-generic-hwe-18.04 xserver-xorg-hwe-18.04 # SERVERsudo apt-get install --ihttps://blog.csdn.net/billbliss/article/details/121953950查看下linux版本

插入蓝牙设配器bluetooth adaptor，

查看下HCI信息

$ hciconfig -a

这边发现信息不全，于是可以下载最新的驱动

https://mpow.s3-us-west-1.amazonaws.com/mpow_BH519A_driver+for+Linux.7z

cd ~/Downloads/ && wget https://mpow.s3-us-west-1.amazonaws.com/mpow_BH519A_driver+for+Linux.7z

解压之后，进入文件夹内部

 可以打开readme.txt

开头内容如下：

===============
  TITLE
===============

The document describes how to support Realtek Bluetooth UART and USB driver in Linux system.

===============
  REQUIREMENT
===============

The supported kernel version is 2.6.32 - 5.7.1

=============================
  QUICKLY INSTALL AUTOMATICALLY
=============================

  $ sudo make install INTERFACE=all
or
  $ sudo make install INTERFACE=usb
or
  $ sudo make install INTERFACE=uart

用全部安装即可

sudo make install INTERFACE=all

现在再看一下HCI信息

$ hciconfig -a

打开蓝牙设置界面，蓝牙已可用。
