PRESET_PLAYBACK
 
Hello,

if the device does not support PRESET_PLAYBACK_ALL (table A-7)
should it NACK with DATA_OUT_OF_RANGE or ACK and ignore?

Likewise, if the device dioes not support the level setting of this PID, should it NACK with DATA_OUT_OF _RANGE for value other than 0sFF or ACK and ignore?

Kind regards
Bernt

I'd vote for a NACK, then the controller knows it was received and explicitly rejected.

For most dimmers, I'd probably ACK the request and ignore the level (treat it like 0xFF). I think either behavior is acceptable though.
