What is KDE Connect ?

KDE connect is a collection of software to make your smartphone connect to your KDE desktop (it also works with Windows and probably Mac OS, but this is not the subject of this article).

With these software, you can:

• Receive notifications on your desktop
• Reply to SMS from your computer
• Send and receive files between your computer and your phone
• Use your phone as a (wireless) touchpad to control your computer or the opposite, etc.
• Execute remote command on your phone or your desktop
• Share clipboards
• And many more

The main issue with KDE connect

Although KDE connect is very good, it performs its magic via network packets, thus with WIFI (it would work with LAN I guess, but I don’t know any phone with a Ethernet port).
WIFI advantages are the ubiquity and the high transfer rate, but it’s also a huge battery consumer.
It also requires your phone to be connected to the same network as your computer which isn’t always possible (like if your computer does not use its WIFI connection or if you have a office network connection where your smartphone isn’t allowed to connect).

You can set a wireless access point on your phone (usually made to allow your computer to share your smartphone’s Internet connection) but that means powering up both WIFI and your LTE modem for a local (non internet communication).

Solution

If you don’t need utterly fast communication with your smartphone (understand, if you can stand that transferring a photo takes few seconds), using WIFI is not required and you can use Bluetooth instead.
KDE connect android and desktop source code have a «bluetooth» path, but they are disabled by default (you need to compile them to have them enabled). I did this but there was no config whatsoever to add the connection. Also, the Bluetooth path is not fully functional from what I understood from the developer’s comments.

If you need this build, just ask I can send you the APK.

The solution I’m describing below involves using BlueZ to start a network connection over Bluetooth. Once the network connection is set up, you simply need to tell KDE connect on your phone to connect to the computer’s assigned IP address, and you’re done.

Prerequisite

On the computer

• A computer with a working Bluetooth hardware and software
• BlueZ installed on the computer and also bluez-utils (required for debugging, you can remove it afterward)
• KDE desktop (sorry Windows and Mac user)
• Linux system (I’m using Manjaro here for the examples and screenshots)

On the smartphone

• KDE connect app (download version from F-Droid since it doesn’t have the Google’s Play store limitation of not dealing with SMS)
• Bluetooth (obviously)

Step 1: Prepare KDE connect on your phone

Install KDE connect from F-Droid (or step 0: Install F-Droid).
Before launching KDE connect, you’ll need to provide some authorizations (depending on your phone, it might ask you by itself, but it didn’t on mine).
So you’ll need to navigate to your Android’s Settings screen and type «Authorization» in the search box.
Then select the KDE connect application and allow it to access the phone (sorry no screenshot here)

Step 2: Allow bluetooth connection sharing

Go to your phone’s settings and type «share» in the search box. Then select «Via Bluetooth» page to allow sharing your connection via Bluetooth.

Step 3: Pair your phone to your computer

In your notification tray, click on the Bluetooth icon, and select «Connect»

Then accept the connection on the phone (you might need to go to the Bluetooth setting page first).

Step 4: Set up the network connection over bluetooth

In your notification tray, click on the network icon, then the Bluetooth icon and select «Connect»

Once it’s connected, use the right rectangle to display the details of the connection (you need the IPv4 address):

Step 4: Start KDE connect link on your phone

Start KDE connect on your phone, and click the submenu button on the top right, and «Add a device by IP». You’ll need to enter the IP address you’ve seen on the network page.

If all goes well, your computer name will appear on the device list on your phone. Click on the icon, and select «Associate». Click «Accept» on the computer and you’re done.

Step 5: Give all authorizations

In the smartphone, you’ll need to authorize all the features once it has correctly connected. Just follow the instructions displayed on your phone and you’re done!

Как настроить Bluetooth в Linux

В связи с растущим распространением периферийных устройств Bluetooth, таких как мыши, клавиатуры и гарнитуры, может быть трудно представить себе, что иногда можно использовать проводные версии этих устройств. В некоторых дистрибутивах Linux Bluetooth полностью настроен прямо из коробки. Такие дистрибутивы, как Ubuntu и Elementary, упрощают настройку и работу Bluetooth на вашем компьютере. Однако другие дистрибутивы, такие как Fedora и Arch Linux, требуют, чтобы вы выполнили некоторую настройку, прежде чем вы сможете в полной мере использовать преимущества Bluetooth на своем компьютере. Вот как вы можете настроить Bluetooth в Linux.

Как настроить Bluetooth на вашем компьютере с Linux

Шаги будут немного отличаться в зависимости от дистрибутива, но основные шаги одинаковы. Если в вашем дистрибутиве еще не настроен Bluetooth, вам сначала необходимо установить Bluez , который содержит стек драйверов для адаптеров Bluetooth, а также утилиты для администрирования Bluetooth через интерфейс командной строки.

После установки Bluez вам может потребоваться установить диспетчер Bluetooth. Некоторые среды рабочего стола имеют встроенные диспетчеры Bluetooth. Например, в KDE Plasma есть клиент KDE Bluetooth. Gnome также имеет встроенный клиент. Если вы используете среду рабочего стола, в которой нет встроенного клиента, вы можете установить клиент Blueman .

Как установить Bluez

Ниже приведены инструкции по установке Bluez в нескольких разных дистрибутивах.

В OpenSUSE вам нужно установить bluez с Open Build Service.

sudodnfinstall bluez bluez-tools

 sudo pacman - S bluez bluez-utils

Другие менеджеры пакетов

Bluez работает со всеми дистрибутивами Linux. Если у вас другой диспетчер пакетов, отличный от вышеперечисленных дистрибутивов, не бойтесь. Вам просто нужно будет найти bluez в вашем диспетчере пакетов, а затем установить все, что включает термин bluez.

Как установить Blueman

Узнайте, как установить Blueman в различных дистрибутивах Linux ниже.

 sudo apt- установить blueman

 sudo zypper установить blueman

Другие дистрибутивы

Чтобы установить Blueman в свои дистрибутивы Linux, вам следует выполнить поиск в диспетчере пакетов в дистрибутиве, используемом для Blueman, а затем установить все соответствующие пакеты.

Включение Bluetooth

После установки вам необходимо будет активировать и запустить службу Bluetooth. Если вы используете ключ Bluetooth, вам сначала нужно будет выполнить следующую команду:

Чтобы включить службу Bluetooth, выполните следующую команду:

 sudo systemctl включить bluetooth.service

Чтобы запустить службу Bluetooth, используйте эту команду:

 sudo systemctl start bluetooth.service

После этого вы сможете начать использовать Bluetooth в своей системе.

Подключение к устройствам с помощью Blueman

Процесс подключения зависит от используемого диспетчера рабочего стола. Тем не менее, мы покажем, как это делается с помощью Blueman, поскольку он достаточно широко отражает процесс.

Чтобы подключиться к устройству, откройте «Диспетчер Bluetooth» в своих приложениях и нажмите «Поиск». Убедитесь, что устройство, к которому вы хотите подключиться, доступно для обнаружения. Когда вы увидите его в списке устройств, щелкните его правой кнопкой мыши и выберите «Подключиться». Возможно, вам придется ввести пароль, но эта информация будет в руководстве пользователя вашего устройства.

Заключение

Теперь, когда вы настроили Bluetooth в своей системе Linux, вот некоторые исправления, если Bluetooth не подключается.
