I have an Alfawise Z1 (2/16) and there was a problem under CE, the BT remote OK button cant working only when i switch to mouse mode. With this little mod i able to use as expected.
First, create /etc/udev/hwdb.d/10-btok.hwdb file and fill with:
Mute c00e2
Menu 70065
Ok c0041
Up c0042
Down c0043
Left c0044
Right c0045
Home c0223
Back c0224
Mic c0221
Vol+ c00e9
Vol- c00ea
Prev c00b4
Next c00b3
Mouse mode
Ok 90001
I have the same situation where the OK/Enter key does not work on BT, but everything else does. The remote is Tekasmi Q9. I am using it on a S905x3 X96Air. I tried to use keymapper app, but no luck, and tried the above. Do I need to change the file name etc to get this to work? Thank you.
