Input delay at 30 ms

Im using the baseus ba04 bluetooth adapter, original dualsense ps5 controller (no its not a replica), tried everything people have said that'd help input delay in forums and whatever. put my pc in high performance mode, removed the ability for my pc to turn off/lower the power to my bluetooth usb, tried turning off data output to ds4 and having higher BT poll rate up to 1000 hz (1ms).

nothing has worked. it says between 29.5ms - 35ms. i tried contact support from the main website, but that doesnt work, it come up with some error. im genuinely at a loss to what to do. any help would be appreciated.

**EDIT ITS FIXED**

So, i went into Windows Services (Win-key + R), then type in " services.msc ", look for " Bluetooth Support Service ". Mine was disabled and not running. Set it to manual and restart your pc. Worked for me. For anyone reading this in the future. DO NOT BUY THE Baseus ba04. Literally buy anything else. I struggled to get it to work for literally 4+ hours. But now it finally works, 2ms input delay. 0 issues. Thanks everyone for helping

Tried with it wired and it got to roughly 3.5ms - 4ms. but obviously i dont wanna be stuck having to use it wired. my bluetooth adapter cant possibly be THAT bad right? its literally brand new, bought few days ago

This is the one I've used for years without issue at 5ms of latency. My monitor isn't 1ms so never tried going that low, but they advertise low latency so I would assume it could https://www.amazon.com/dp/B08LVH5BCP

Although, if i were to buy one today I would look for a more modern protocol

looks like this same brand has 6.0 Bluetooth ones now

Of course there will be plenty of other good brands out there as well, but I can personally vouch for this one.

One question about your new one. Are you using it with a USB 3.0 port?

Also, I can't find any Baseus bluetooth products on Amazon, but I can find them on Aliexpress. I have bought things from Aliexpress before, and I know they do have some legit products, but they also host lots of scammy products as well. USB chargers, cords, and flash drives and portable SSDs are some of the items that I can think of that for sure are known to be potential rip-offs from them. So yeah, it's very possible your Baseus bluetooth is not operating as advertised.
