Hi All,

I've tested this series on six (6) different Intel based devices which use
the RTL8723BS chip and Bluetooth worked without issue. I added the patch
series to the v4.17-rc7 kernel and used both an Ubuntu and Lubuntu 18.04
user space together with the firmware as referenced by Martin in the
original RFC ([0] https://github.com/lwfinger/rtl8723bs_bt in [RFC v1 0/8]
Realtek Bluetooth serdev support (H5 protocol)).

Besides the successful pairing of a Bluetooth mouse I ran some additional
confirmatory commands and include the output below.

I offer my

Best regards,
