Project goals• Controlling Furby toy via

bluetooth

– Implement Free2Move F2M03AC2 bluetooth module

– Control Furby movements from PC

– Transmit audio signals between Furby and PC or other audio device.

What is Free2Move F2M03AC2 BlueTooth module ?

• High integrated BlueTooth module.– Main features:

Integrated antennaUART interface (serial port

communication)Analog and digital (PCM)

voice interface for up to 3 simultaneous voice channels

BT data stream divided into Wireless UART data and SCO channels (audio).

What I have already finished?

• BT (BlueTooth) communication board– implements Free2Move bluetooth module– Converts wired data paths to the wireless

bluetooth signal.– Provides data transfer - serial port (RS-232),

using the UART capability of Free2Move module.

– Provides audio transfer (LINE-IN, speaker, and microphone connectors)

– Supports configuration through Free2Move software.

BT communication board- alternative usage -

• 2 boards in the pair can be also used as wireless serial port (no virtual serial port like bluetooth dongles, can be used with any computer having COM port, independe)

• Benefits:– bluetooth boards are transparent for software– No driver needed, just connect to the COM port by a cable...

What needs to be done?

• Furby has been modified for wired control by previous project but unfortunately doesn’t support Bluetooth yet.

• Furby electronics must be reworked to support bluetooth.– Implement Free2Move BT module.– Place microcontroller with proper program into Furby to

control movements and drive communication with PC.– New electronic parts must fit in Furby’s body (problem

with physical size limitation).

• Software on the PC side which will provide user interface.

Conclusion

What is done:• BT communication board

What am I working on:• Testing two assembled BlueTooth boards.

What is to be done:• New electronic circuits for Furby to allow Furby to

communicate by the BlueTooth.
