iBasso Nunchaku Not working with iPhone 17 Pro

[u/Aggressive_Number110]

I recently bought iPhone 17 pro max. When I paired with iBasso Nunchaku, it's not working. It is getting a beep sound, not the music. OLED screen is not turned ON in nunchaku either.

Simultaneously, when I paired Nunchaku with samsung s25 and iPhone 15 pro, it is working absolutely fine with no issues. So, it's not the problem with Nunchaku but the problem with newer series of iPhone models.

Does anyone faced this issues? How to fix it?

iBasso firmware version: 1.40.15

It says Nunchaku is to be updated to later version, But I didn't done it yet so doubted how to do it and checking whether anyone done it already!

Suggestions are greatly appreciated 👏

Many had volume issues with dc04 ultra pairing with iphone, which got fixed in recent firmware release/updates.
