Low polling rate via Bluetooth

[purplebar0]

I observed a significantly lower polling rate when using a DualShock 3 wirelessly through an OGX-Mini-flashed Pico W:

• 00:00: Via USB (tested on original Pico)
• 00:18: Via Bluetooth

From a short amount of testing, this does appear to make the controller feel significantly less responsive and introduce some delay, so where's the bottleneck?

Edit: The most apparent issue is lack of inputs while button mashing, likely caused by short inputs.

I think this may be some kind of bug with the pico w or pico sdk, I've been reading this thread on it: raspberrypi/pico-sdk#1342 It is on my radar and I've been working on an update that should improve responsiveness a bit, but I don't have a full on fix for this as of now

Does Pico 2 W make any difference here? I noticed that the wireless chip is the same (CYW43439), the difference being that the board supports BT 5.2, so I'm guessing the answer is no.

I also have the components to create a Pico/ESP32 hybrid, I'm guessing that would also be more stable?

Either way, I guess it's best to see what can be done here first, since I already made a pretty clean and sweet Pico W setup in a case.

Late response, but I just tested and Pico 2 W has the same kind of lag as Pico W.

I'm testing a Gamesir Cyclone 2 with a Pi Pico W and this controller has 3 bluetooth modes labeled "Android/HID", "PC/iOS/DS4" and "Switch/NS". In both android and pc modes the polling rate is very low, but in switch mode the controller has basically perfect input lag/responsiveness. But, in switch mode the triggers aren't recognized at all by the ogx mini for some reason.

Edit: i've tested a switch 1 pro controller and the trigger on it hasn't been recognized either, but it also has great responsiveness on the other buttons. Tested a dualsense on the other hand and all buttons work but it's very laggy.
