Description

I try to setup a sharp tv, I use the included ir set, those ir command have strange behaviour, they all correct as I test but I have to hold the button or click the button on screen a few times continuously to make the tv receive the command. I already put the dock close to the TV but nothing change.

How to Reproduce

1. Click the volume up or down
2. No respond if only press once
3. Hold the button continuously for 2 second the tv will response finally.

Expected behavior

Click once and get response immediately.

System version

V1.4.5

What part of the system affected by the problem?

Integration

Additional context

No response

It’s like all button need to be double click to make it work, don’t know it’s about the speed or length of sending out the IR. Need to fix that to make the remote work.

And when I try to record the IR code from the original tv remote, the dock can’t read the IR code from it, but the tv can receive the IR command, so maybe the tv and the remote have some odd IR behaviour?

And the Apple TV 4K can learn the TV remote without problem while the remote two can’t.

I find in the GitHub for other irremote, someone mention a protocol about some of the sharp tv that’s “Protocol demands that the data be sent twice; once normally, then will all but the address bits inverted” that’s quite match the situation I have, my TV will react to remote2 when I double click the button, and it can explain why the dock can’t record the ir code it receive. But I don’t know what I can do to achieve that….

So when will the dock learn more IR code format to help me to control my sharp TV. Really need it too make the setup work. Apple TV and a IR blaster for Tuya call learn it without problem but the remote2 can’t.
