IR CODE can’t learn by the dock

I have a sharp tv from Asia that’s the code can’t learn by the dock, but can learn by the Apple TV. And if I choose those code provided by remote2, those code won’t work if I only push once, like I have to turn volume up of my tv by push twice very shortly or hold the volume up button to make it work. Any suggestions? Thank you so much.

Have you tried looking at the Global Cache IR codesets? There are about 7 different Sharp ones that are probably worth a try for you.

Try all the set from global cache and all working set show same behaviour, need double click or long press to work….
