I believe it should be loading rtl_bt/rtl8821c_config.bin and rtl_bt/rtl8821c_fw.bin
The line:
| Code: | | [ 3.992721] Bluetooth: hci0: rtl: examining hci_ver=08 hci_rev=000c lmp_ver=08 lmp_subver=8821 |
I believe indicates the hardware needs rev c firmware.
This works correctly on Kubuntu 18.04. Kubuntu is using linux kernel 4.15.0-38
