Re: [WheelCommander] Bug with new Wizard Mode setting

[plskeggs@xxxxxxxxxxxxxxxx]

Milton,

Thank you for your patience.  I've fixed the bugs related to interactions
between Short Cmd Mode, Slow Comms Mode, and the Wizard.  The bottom line
is that once you set either or both of these modes, when you leave and
reenter the Wizard, it didn't know how to communicate with the WC-132
because the responses it was getting back were not what it expected -- it
didn't know that these modes were on.

Another bug caused the Wizard to unintentionally corrupt the mode byte,
which is what caused the motor spinning issues you saw.

Anyway, if you can wait, I'll get it into the next release at the end of
this month.  I will also issue an update to the firmware to address the
red LED issue you mentioned separately.
