Asus Rog Strix Z370-I Gaming Sleep issue in Mojave 10.14.4

Hi,

I'm having some issues making sleep work on this system.
This are the spec of the system:
Asus Rog Strix Z370-I Gaming
Intel Core i7 8700
Sapphire Radeon RX 570 4GB Mini
GSkill TridentZ 3200Mhz 2x8GB
DW1560 WiFi+Bluetooth

Everything works on this system BUT sleep.
The system tries to go into sleep mode BUT it BOUNCES back immediately.
Being this a Z370 I thought the usual UEFI drivers would be enough.
I have created a UBB SSDT. Such SSDT assigns port type Internal 255 to the Bluetooth Device.
I have also disabled the Asus Aura Synch USB device present on HS13 just in case.
Tried with Clover r4920 and r4934 with updated UEFI drivers but it makes no difference.
Once in a while the system goes into sleep IF I give the sleep command by hand.
Automatic sleep always produces a bounce.

I attach the EFI folder.

Thanks anyone for their help.

Ok found what it is.
It's bluetooth. If I disable bluetooth sleep works.
I'm using a DW1560.
In the USB SSDT I've specified HS14 to be 255 (internal)
This module requires these two kexts in L/E to work:
BrcmPatchRAM2.kext
BrcmFirmwareRepo.kext

I've installed the exact same type of module on different motherboards and sleep was never an issue.
Could it be the one inserted is faulty?
Thanks
