Yes, it is what i'm doing now and all is OK, [wiimote] is created.

What i do with this Make.local now, where i put it ?
Now sending [reportMotionplus 1( to [wiimote] return :
angle_rate 8000 8050 7870
low_speed 1 1 1

The problem is i get always 1 1 1 with low_speed. Because of the
Make.local file ?
