Pencil surface Pro 4

Good morning, I have a surface pro 4 with its touch pen, but I am testing on my Chuwi MiniBook 8 ", and it does not work for me, the fact is that it synchronizes correctly and when pressing the upper button it performs the assigned function, but it does not write or does the mouse function.
It may not be compatible ?.

Thanks for your help, and sorry for the English I use a translator.

A greeting.
