The HC05 Bluetooth Module is another possible candidate for the radio system.

It has a potential of 1.3Mb/s transfer rate.  It is priced at US$5 in singles.  It uses bluetooth serial port profile. It doesn’t appear to have FCC certification. It would come programmed from manufacturer.

Advantages to the design:

• Easy to use
• Low Cost
• good speed

Disadvantages to the design:

• Lack of FCC certification could force a redesign.

The FCC problem is too big, this radio is removed from the possibilities.
