Ordered this wifi module with RTL8723bs. Driver is present in the factory rom. Arrived today. Pulled that sh.tty wifi module and soldered the realtek module instead. Now wifi working with factory android and with LE.
I have not tried this, but pulled the LE sdcard from my Mecool M8S Pro+ S905X, pushed to tanix box, LE started with reset button. Remote is different, did not work with mecool config of course. Wifi is the same crappy SCI board as the Mecool's, so no wifi. Lan works, mini wireless keyboard/touchpad works, videos play.
Ordered some RTL8723BS modules for both the mecool and tanix boxes like this: [link]
I will swap and try them, RTL8723BS driver modules are builtin both of the roms, and it is wifi+bluetooth chip!
