Would it be feasible to implement Bluetooth in KDE Connect? I do not have a Wifi network at my house and therefore cannot use KDE Connect. If Bluetooth was added you could also be connected anywhere, even if you didn't have Wifi access.

Erm, KDE Connect IS using bluetooth to connect...


Currently running Kubuntu 20.04, Plasma 5.18.5, Frameworks 5.68.0, Qt 5.12.8, kernel 5.4.0-46
FWIW: it is always useful to state the exact Plasma version and distribution when asking questions in this forum, makes it easier for us to help ...

Is it? I couldn't get Bluetooth to work... It wanted a Wifi network and wouldn't do anything with Bluetooth.

My bad...

I also couldn't get connections over Bluetooth to work :(

Bluetooth is up and running. My android smartphone and the PC are paired. The BT interface on the PC is set to be visible. I can transfer files over BT between PC/dolphin and my smatphone. But i can't pair the both devices in KDE Connect. They can't see eachother. If it's really work over BT, what a'm doing wrong ? Must KDE Connect be separatly compiled with BT support ?

KDE Connect version is:
Code: Select all
kdeconnect            1.4-0xneon+18.04+bionic+build24
kdeconnect-plasma      1.3.3-0ubuntu0.18.04.1
Android App: 1.13.7


Neon: 5.19, Plasma: 5.19.4, Frameworks: 5.72.0, Qt 5.14.2, Kernel 5.4.0-47-generic (64bit)

pairing devices is independent of applications like KDE Connect, either you can pair your PC with your phone or not, the app is just a layer on top of it. My installation is very much vanilla Kubuntu with the bluetooth stack that comes with it, my laptop bluetooth controller is equally standard Qualcom on an old Lenovo Yoga 510:
Code: Select all
hciconfig --all

Are you sure you have bluetooth enabled on your PC?

In other words: do you have bluetooth enabled on both your devices and did you pair them?

I see, your USB Dongle support BT 4.1. Do you know, if this is a requirement for KDE Connect ?

Yes, BT is enabled and set to visible on both devices. As i already said, transfer files from/to PC with other tools (dolphin) works fine.

Nothing to see, if i press the Refresh button

And also nothing to see in Android (in german):

The both items [email protected] are my WI-FI connected PC's at home

I don't know about the requirements for the Bluetooth protocol version, but could well be that 4.0 is too old.
Maybe try looking up specifics for the Bluetooth protocol versions, phones nowadays support version 5 as a standard, so yes, 4.0 looks quite outdated to me. Even 4.1 on my laptop is rather old, as this laptop is not the newest model either.
Not my speciality, fact is this is the wrong thread for this kind of problems, as it is in no way related to what KDE Connect offers, and I am not even sure this is in any ways Plasma or KDE related, but a hardware issue.

I found out that the bluetooth link provider is optional and must be enabled (BLUETOOTH_ENABLED) when compiling KDE Connect.
How can i check, which flags/options were used on building KDE Connect for Neon ? Is this stored somewhere in .deb packages ?

Or in other words, is someone here, that successfully paired Android with KDE Connect on Neon (using packages from repo)?

Please make a new post in KDE Neon, this does definitely not belong in Brainstorm
