The Force Feedback configuration is sent continuously over the wireless link, which takes the form of a 31 byte payload. The wheel is capable of supporting 4 simultaneous effects, plus an additional auto-center effect. The various effects are upload into 'slots', the format is as follows:
−: Bytes .. - Unknown
+: Bytes 1..4 - Unknown
−: Bytes - Effect Slot 1
+: Bytes 5..10 - Effect Slot 1
−: Bytes - Effect Slot 2
+: Bytes 11..16 - Effect Slot 2
−: Bytes - Effect Slot 3
+: Bytes 17..22 - Effect Slot 3
−: Bytes - Effect Slot 4
+: Bytes 23..28 - Effect Slot 4
−: Bytes - Auto Center
+: Bytes 29..30 - Auto Center
−: Bytes .. - Unknown
+: Bytes 31.. - Unknown
The selected slot for an effect is encoded into the 1st byte of the OUT-Endpoint write. Multiple effects can be active at any time, but it is unknown how multiple forces are rationalized by the wheel.
