KDE connect with Raspberry Pi

Issues & Assistance Unsupported hardware | Dual boot

Hi,

I can connect to my phone using KDE connect, I can also connect the phone and the Raspi. But Garuda does not detect the Raspi.

I don’t think it’s related to my network. Anyone using KDE connect on the Raspi successfully?

This is NOT simply about “unsupported hardware”:

Phone — Raspi: Works.
Phone — Garuda: Works.
Garuda — Raspi: Doen’t work.

I don’t think that’s even supposed to work…? I thought kde connect was used to sync messages, notifications and other phone utilities from your phone to desktop, i.e., phone app transfer’s phone data over the internet to your computer. But I don’t think the computer transfers anything back to the phone except media control.

Raspberry being a desktop itself I don’t see how they would connect with each other unless you somehow manage to run android’s kde connect on it to transmit data from raspbi to anything else. Even if it does connect I don’t see what it could possibly transmit.

I moved this to unsupported hardware because Garuda does not officially support the Raspi.

Fascinating, how KDE Connect is still so underused, underdeveloped and not well known. It’s at least the best we have.

No, it’s also for file transfers. Why would a device not show up in the search just because it’s a PC or Raspi?

Anyways, I looked it up, and it was possible already six years ago, but other people report the same problems: Reddit - Dive into anything

Garuda is not on the Raspi, it’s on my PC. I want my PC to connect to the Raspi. It’s a problem of KDE Connect on my Garuda PC. The only thing that seems to work reliably on Linux to move files between systems.

All devices are on the same network, since the phone is the hotspot.

I know this is deviating from the topic but if it’s just for file transfers is it necessary to implement kde connect? Why bother with something that’s not working and not use something simpler instead? Files can be shared over bluetooth as well. → usb - Share files between 2 computers via bluetooth from terminal - Ask Ubuntu

or use something like megasync and it’s free 20gigs of storage to sync files between the two devices.

Bluetooth isn’t that great either and it can have issues. In regards to other solutions, I don’t want to go through the internet for my computers at home. KDE Connect is on the way to become the standard for this.

This is possible, but not necessarily true. It depends on the configuration of the mobile device. Some hotspots intentionally isolate connected devices with subnetting, preventing them from communicating directly. Check your phone for advanced hotspot settings or features like “AP Isolation”, which may be preventing the two computers from seeing each other.

If you aren’t sure if they are on the same subnet or not, post the IP addresses and subnet masks of the devices into the thread.
