The
Simple Wireless Bluetooth Mobile Phone Headset was built
using a Bluetooth module and PSoC CY8C26443 microcontroller.
Few other components are needed because of the PSoC microcontroller's
beneficial internal peripherals. The other components
used include: a 3.3-V power supply; 16-V, 47-µF electrolytic
capacitor; two 300-W resistors; two SPST push-button switches;
and two LEDs.
The
device consists of two units. One unit is worn by the
user as the headset; the other unit is connected to the
mobile phone via its handset interface connections. The
Bluetooth module provides the wireless interface between
the mobile phone and headset. The CY8C26443 controls this
module via a UART interface running at 57.6 Kbps, 8 bits,
1 stop bit, and no parity. Another interface, from the
Bluetooth module to the CY8C26443, enables voice data
to be transmitted.
