I did but it only worked with v2.21 but not 2.31. I can’t find LIB file for 2.31.
If the APP file needs the LIB file, I suggest both files to be included in a folder.
As you can see, Paul’s 1.5 is also not accompanied by it’s LIB file. I tried upgrading
to that file too and nothing happened. In the firmware upgrade manual, there’s nothing
mentioning about the LIB file accompaniment. I think that is just misleading. Upgrading
the firmware is not as simple as I first thought it should be.
