Please read the documentation carefully before using the kext or submitting an issue report.
How it works¶
On Realtek combo cards the Wi-Fi may be PCIe while the Bluetooth radio is an internal USB device. This kext matches that USB Bluetooth device and uploads its patch firmware. The actual chip is identified at runtime from its HCI version, so a board only needs its USB ID present to be picked up.
Both Realtek firmware formats are supported — v1 (Realtech) and v2
(RTBTCore).
