I'm also interested in. I have configured VU+solo2 remote and one IR command "CURSOR UP" does not work.
There is a way how to update buttons behavior with custom PRONTO codes -via export configuration (JSON file), modify code and import again.
Unfortunately I cannot find PRONTO code for CURSOR UP command.
code provided by Flirc team does not work.
Ok, I did it. Found correct code for CURSOR UP and updated exported raw JSON file - remote controller works fine.
To anyone who interested:
1. export Remote configuration from SkipApp
2.edit file and replace assigned code with your ones in PRONTO format
3.save and import new configuration
