Prior to the arrival of my FLIRC and Xbox one media remote I'd been using the official XBMC Android remote application to control both XBMC on an Ubuntu / Win PC and also OpenElec on a Raspberry Pi and a Cubox-i.
I too had the endless repeat problem on the PC, Pi and Cubox-i. That was until I selected the 'Send Single Keypress' option in the application's settings. Thereafter everything has been smooth and error free. With only the slight inconvenience of thumb ache while navigating the occasional long list or large media library.
I had hoped that my new remote would seamlessly replace the smartphone - it's a pain having to boot up a phone every time you want to play a video / track - but I was disappointed to re-encounter the same problem with endless repeats. Though this time without an obvious solution: I've tried every inter key delay, and selecting and deselecting all the advanced options but find the remote is still almost completely unusable.
The application solution and the problems others have encountered suggest to me that perhaps the problem is with the Kodi/XBMC software and not the FLIRC firmware. And that until the root cause is remedied it might be an idea to circumvent the annoyance by adding a 'Send Single Keypress' option to FLIRC's settings. That's if it's technically possible. And not too much work.
Thanks for your time and hope this helps.
