This week was Thanksgiving, so time to work was limited.  We demonstrated that each individual module was working.  Our central Bluetooth chip also arrived and we began working with integrating that into our design.  The central unit was able to connect to all of the peripheral chips, but we are currently limited by the fact the central and peripheral chips have different baud rates.  We have ordered another set of Bluetooth chips as a backup in case we are unable to change the baud rate on either of the current chips.  They should arrive by the end of the week.  We no longer plan to create our own seven-segment display due to time and budget concerns, but we are still planning to solder the parts to a PCB and put it in a case. There are also a number of small things that need to be polished, such as cleaning up the LCD display.
