galileo13 got a reaction from k0nrad in BrcmPatchRAM2 for 10.15 Catalina (Broadcom bluetooth firmware upload)
Can confirm that this works.
Had same problem, BT didn't work after boot, only on wake.
After following linked tutorial for custom SSDT problem was fixed.
Needed just to reinstall kexts (with Hackintool), reboot, sleep, wake (for firmware upload) and then all was working fine on every following boot.

Fixed my problem by using the "old" RehabMan method to create a custom SSDT for USBInjectAll.kext instead of the USBPorts.kext created by Hackintool. As a benefit several other problems and lags also disappeared. Nice! :-)
