Hi, I’ve an issue with QR Codes. I already use them from a lot of time in order to share access to my projects with other people.
Now the problem is this: within the same login account I have realized three projects and have shared the relevant QR Codes. But only the first works, the other two doesn’t work both with iOS and Android. Of course the projects are running and there is plenty of energy.
The answer on iOS is: “Can’t load project” (in red)
The answer in Android is: “Couldn’t connect to the server. Please check the internet connection” and then “xxx app is no longer available, sorry”
Of course the internet connection is ok and the app is available.
I precise too that I have already realized many projects within the same login account each with its QR code and everything worked fine.
I work with the last version of Blynk both on iOS and Android and use a local server. Maybe the issue could be linked to the last update of Blynk app?
I use the last version of Blynk app but I’m forced to work with an old version of the server for the problem of raw files. Do u remember? But consider that the last working QR Codes was created no more than 2 weeks ago.
If you have need to stay with an older version of server, then you also need to avoid upgrading the App and Library as well, otherwise the current progress the developers are working on in newer components will eventually conflict with older components.
Backward compatibility can only go so far before it becomes an anchor.
I guess you can try Googling for an older version of the App APK to revert to and some of the older libraries are still available here:
Or just embrace the update and change how you use data in the newer Server.
I’m sharing my project (not clone) - running on my local server on RPI - and after a while is not working on the shared side: when I scan the code is loading…and loading and nothing is happening; first time when this happened I have regenerated the QR code and worked; then, when it didn’t work again, I checked and compared the 2 QR codes and observed the IP of servers was different (I’m using a DDNS to connect to master project). Is my assumption correct - the reason for shared project not working? if yes, is there a solution to this? for ex QR code to contain the DNS / DDNS and not the IP (numeric format eg: 86.127.186.xxx). thx
