First, on Android, make sure you’re running 1.23.6.3. There was an update that came out immediately following 1.23.6.
There is a free program that will let you copy that long long code easily from Linux to Android or the reverse. It’s called KDE Connect. On Linux I’m pretty sure it’s in app stores and on windows it is in the Microsoft store and on Android it is in Google Play. Does not require KDE desktop.
Once you connect your cell to your Linux machine you’ll be able to transfer the clipboard from cell to Android. That way you’re not sending your private code out by a email and text messaging doesn’t work without help on Linux.
With KDE connect you can also send and receive SMS text messages from your Linux machine when connected to your Android phone. On Linux simply open the KDE connect sms app and send a text message to your cell phone number and the long code in the text message will arrive on your cell phone where you can then paste it into syncthing.
Or, on Linux, save the long code to a simple text file. KDE Connect can then send that file to the downloads folder on your cell phone. Then open with text editor.
with yet another fresh install the barcode is detected.
however I am unable to add any devices.
see my bug report, and pardon me for the weird screenshots
BTW: installing KDE connect would bring in 163 packages, I dislike KDE and don’t want any of it on my system.
Ah, OK. I had no idea it would want to load so many packages. It didn’t do that to me. It does not have any relation to the KDE desktop so no worry that it loads the KDE desktop software. You’d probably prefer the option in the next paragraph.
For future reference, there is another option that requires No software to be installed. It’s called sharedrop.io. It can transfer one file like a text file from Linux to Android by simply going to that site while both devices are on the same local network subnet. The site uses WebRTC to enable peer to peer transfer much link Syncthing. Send-anywhere.com can also transfer a file any device to any other. It requires an Android app from Google Play. It operates only in a browser tab on two or more devices. That’s why sharedrop is such a neat option to simply move one file.
It’s a neat tool to keep in your bag of tricks.
Best of all there’s nothing to install. (And Free)
