Hi Slava. Any plans for 4.4/libnemotransferengine-qt5-2 compatibility? Thanks

slava's picture

Version 1.2.0 should work with Sailfish OS 4.4

slava's picture

Honestly speaking, I'm tired of chasing those API changes around. And since I'm not planning to upgrade my daily phone to 4.4 any time soon, I don't feel much of a pressure to do anything about it. If at some point I feel that I've got nothing better to do, I may give it a try. I created an issue on GitHub to track the progress (if there will be progress):

About sharing contacts. I have done it before using other means, so it may just be too long. Stripping the contact photo before generating the code could help.

slava's picture

Yeah, that's been sitting on my todo list for such a long time...

maier's picture

You could support both ways with a config setting a) skip imsge b) scale down so noboby can say something and all should be happy for a working solution. To transfer a ~5GB photo by QR is unpossible ;)

maier's picture

Thanks) ... If I share a contact with photo I always get a info it's to big. This is one of the best utils!

slava's picture

Yeah, it's a known issue, but I haven't gotten around to fixing it yet. The photo would have to be stripped. One could imagine scaling it down but IMO that wouldn't be worth the trouble.

Hi Slava. I'm missing sharing of calendar events via QR a lot. Issue 18 on github.

elkiaer's picture

It's ok now after the latest updates on the app.

Do not insall on it will break down the sharing function, incl. MMS.
If upgraded to, the app must be uninstalled.
For uninstalling, slava please inform.

slava's picture

Hmm... It works for me on 3.3.0 and beyond. But if you feel like uninstalling it, run

pkcon remove sailfish-qrshare

from the command line (as root)

Karry's picture

Well, I have the same problem on SFOS Sharing page is empty. When QR Share is uninstalled, at least system plugins are visible... With QR Share, I see these messages in log:

[W] 2020-04-30 0:01:24.628 10196 unknown:0 - void DeclarativeTransferMethodsModelPrivate::modelDataReceived(QDBusPendingCallWatcher*) "Did not receive a reply. Possible causes include: the remote application did not send a reply, the message bus security policy blocked the reply, the reply timeout expired, or the network connection was broken."
[W] 2020-04-30 0:01:24.630 10196 unknown:0 - void DeclarativeTransferMethodsModelPrivate::pluginMetaDataReceived(QDBusPendingCallWatcher*) "Did not receive a reply. Possible causes include: the remote application did not send a reply, the message bus security policy blocked the reply, the reply timeout expired, or the network connection was broken."

Where can I see more details? It has d-bus activation? How can I debug it?

slava's picture

Let's hope that version 1.0.12 fixes this problem, although it remains a mystery what's actually the problem, let alone what's causing it.

icon size too small on Xperia X SF qrshare-1.0.3-5.1 (people). Thanks!

slava's picture

The icon is supposed to be generated at install time to match Theme.iconSizeMedium (which depends on the screen resolution). That's what this app is for:


There was a problem with the very first version (1.0.0) - it was deleting the new icon during upgrade. So if you were upgrading from 1.0.0 - that would explain it. Try reinstalling the package.

amaretzek's picture

"pkcon remove sailfish-qrshare" and then "install" solved the problem. Thanks

As a github pull request like this: https://github.com/monich/sailfish-qrshare/pull/1

objectifnul's picture

Improved with Jolla-Browser, thx. However, saved QR's in the gallery are too blurred (less than 800 bytes) and unreadable.

slava's picture

Version 1.0.2 saves larger images to Gallery. Typically, every pixel gets converted  to 5x5 square (the actual number depends on the code size and the screen resolution - squares could be smaller but never larger than 5x5). Those images should be readable now.

slava's picture

The generated PNGs are perfect pixel-to-pixel copies of the QR code, black on white and with a 1-pixel white square around it. They are not blurred or anything. It's just that Gallery assumes photos and will blur and interpolate pictures no matter what you do. Of course, if I turn pixels into squares (2x2, 3x3, 4x4, whatever), the interpolation effects will become less noticeable, but that would essentially mean doing the resizing for the Gallery app.

It's really a problem with display, not with generation of images. And I was actually able to decode QR codes from the Gallery with CoreReader from Jolla Store, which convinced me that this is good enough. They don't look great in Gallery, I agree, but they should still be decodable.

Pohli's picture

Wouldn't a vector graphics file format like SVG be more appropriate?

slava's picture

Gallery doesn't seem to support SVGs. And to me, one pixel per bit seems to be quite adequate, if not perfect, format for this particular purpose.

slava's picture

Not really... With QR Clip you can convert arbitraty selectable text to a QR code, this one converts the whole thing (provided that sharing is supported by the application in the first place)

slava's picture

And another important thing - QR Clip is compatible with Jolla Store and this one isn't.

maier's picture

My special Thank you for your support ) It is working fine. Only the two points from the comment before are not working. As initial version super.

objectifnul's picture

Promising. For most of my contacts, I get an error: "Text too long for QR code".

I wish it working with Jolla Browser (currently: "Nothing to share").

slava's picture

I have to check what exactly browser is sharing. As for contacts, those most likely include the picture which makes them too big for a QR code. Some pre-processing might help there. I'll take a look when I have a chance.

martonmiklos's picture

FYI I have did some coding around shortening the contacts for sharing via SMS:
