1 Application Overview

The Cubicle Doorbell utilizes the micorocontrollers’s EUSART peripherals to establish a connection between two MikroElektronika RN4678 Bluetooth® Click™ modules (based on Microchip’s RN4678 Dual Mode Bluetooth module). These modules facilitate the transfer of data which occurs when the doorbell button is pressed. When the button is pressed, the door module sends a signal via a Bluetooth connection to the desk module to alert the person inside the cubicle that someone is at the door and trying to get their attention.
