Not sure if previous version of library is being installed

Development Tools IDE 2.x
1

Hi, would appreciate some clarification, I'm not sure if this is a bug, poor UI design or if I am doing something wrong

I'm troubleshooting the RF24 library and a suggestion was to roll back to a previous version, which I did in Manage Libraries

Click install, it says installing, updating list of libraries... etc.

But then it still says the latest version is still installed, I would expect it to say 1.1.7 INSTALLED

image

Granted, it's greyed out, so that's a change, but when I hover over the library again, we are back to square one, repeating the process gives the same result.

Have I rolled back the library? Or is the librarys manager telling me correct information

Have you restarted the IDE since installi8ng the earlier version of the library ?

I have tried it and no change

I clicked install on v1.1.7, closed down the manage libraries window, saved my sketch, reloaded my sketch, went back to the manage libraries window and it said the v1.4.7 was installed :thinking:

Delete the library and install ithe version that you need
What problem are you trying to solve that needs an old version ?

You can check the library.properties file (C:\Users\yourUserbname\Documents\Arduino\libraries\RF24\library.properties). I had to roll back twice, first time it went from 1.4.6 to 1.4.7 (maybe I clicked wrong) and next time I only had an install option (not an update option, possibly because you can't update if you are on the latest version).

I'm new to this, I can't find on the github page here a link to previous versions of the library

Can't you install it from the Library Manager ?

Done, I got 1.1.7 INSTALLED in the library manager

That seems to have done what I wanted it to, unfortunately the project still isn't working so it looks like that wasn't the issue. I will buy some new transmitters and see if that solves my problem
