Servo Communication Error With Latest Tracker GUI

[tonysdsmt]

With the latest tracker GUI release (AntennaTracker_withRFD), we are getting a communications error with our servos.  They will execute commands from the Pololu Maestro Control Center and they were working well with the previous tracker gui releases, but we're running into an issue with the latest release. On startup the gui correctly finds the Maestro Command COM port, but as soon as we hit 'Update Settings' the error light on the Maestro board lights up and the Control Center's error tab reads "serial protocol error" -- error 0x0010.  This error remains on/unchanged when we try manually manipulating the servos through the "manual control" tab, click "move antennas to center", or attempt auto-tracking.  If cleared from the PMMC, the error will return any time a movement command is issued.

Has anyone else had an error like this, or know of possible solutions?

Fixed, our problem was with serial and channel settings in the Maestro Control Center.

Just another note to this post: typically you can only have one program accessing a comm port at a time, no two programs or processes accessing the same comm port at once. You can get away with having the Maestro Control Center open at the same time as the tracker program but you have to have "USB dual port" selected in the serial and channel settings of the Maestro Control Center. On all other programs and comm ports, you can only have one process/program at a time access any com port.
Or...if you ever have a problem where the antenna tracker will not run the servos make sure "USB dual port" is selected.
