Need help! Airdrop has a problem with my Hackintosh after wake up every time

[lamar8]

Hello everyone, I bought a WiFi card BCM94360CD (including BT4.0) in recent days. It works well basically, both airdrop and handoff. But an annoying issue came.
Problem is that airdrop doesn't work every time after wake up from sleep. If I reboot the machine, it works again. Then I try to find out the reasons.
Finally, It seems I found the reason, but can't solve it. I find that the "airdrop channel" changes from 149 to 6 when it wakes up. My other MBP2018 never has no such issue because it always channel 149.View attachment 439849


Does anyone have any advice about solving this problem? Many Thanks.

My machine:
CPU: E3 1270v3
GPU: RX 480
Motherboard: H81M-K
WIFI CARD: FV-T919 (BCM94360CD)
OS: 10.15.1

Same issue, not idea how to solve this

I know about this issue a little more now. I install a Mojave today and find it has no issue at all in 10.14.6
So this must be a small bug only for Hackintosh. I don't think this will be fixed in 10.15.x later by Apple, because it just happens on Hackintosh.
I also tried to replace IO80211Family.kext from 10.14.6, but it doesn't have any effect although it also works well for other functions. It should have bugs in other kext files or something kernel files
Is there any superman who could solve it? I keep waiting ...

Interesting. Let's see if others face the same issue.
I wonder if your card uses a USB port for the Bluetooth ? Mine yes, and I have a doubt regarding SSDT for USB. I need a true USB-C in order to do a final check.

Yes, My wifi card is on the PCIEx1 slot, and it has a cable connection to the USB port for the Bluetooth.
