Tested 20170301 on minix x8H (S802) and minix X8H Plus (S812)
Wifi works on S802 but signal is not optimal (but acceptable). Bluetooth works for me with an speaker.
wifi and bluetooth don't works on S812. At first it seems to works. The networks are listed and you can connect and appears a correct IP.
But when you try to access the net don't work.
I think minix x8h (s802) uses an AP6330 chip and minix x8h plus (s812) uses an Ap6335 chip. I don't know if this is useful for you...
