@Isolved: the solution of the problem was throw away 2.4 dongle and connect gamepad through standard pi Bluetooth - work fine

I want to bring up this topic again!

As I have noticed from experience, at SWITCH mode sn30pro + retropie could has much delay! And it's awful :(

So, in 2024 year, could someone tell how to get work sn30 at XINPUT mode? ( with both working Triggers and "hotkey" buttons)
