Hello, everyone. Sorry for my poor English!

SSD1: WD S750(windows10)
SSD2: TOSHIBA Q200(Big Sur oc0.6.3)
WIFI/BT: BCM943602CS(PCIEX1 with USB conector for Bluetooth)

keyboard： flico minila air (Bluetooth)
mouse: g603 (Bluetooth)
both os works well, (use pcie wifibt card)but after sleep, my keyborad and mouse can't awake up my macOS,so I bought a m2.key_e adapter from taobao instead the pcie adapter ,

after I installed, first power up in macOS ,it looks great ,keyboard and mouse both can wake up the sleep,handoff,airdrop,auto unlock all works great!Both keyboard and mouse in windows and bios works fine too.
but when I restart ,the windows and bios and oc also can use my bluetooth keyboard,
when the system in macOS, wifi always ok, but sometimes the bluetooth hung-up,like this

or this

sometimes it works, and I can't find the rule,
in system log, it shows

can somebody help me fix it?
I tried brcmbluetooth kext, usbports kext, unfortunately ,it don't useful.
