The PIC18F87J11 microcontroller issues the required ASCII commands for the demo application to configure and set up the wireless Bluetooth nodes. After successfully establishing a Bluetooth connection between two nodes, data in the form of strings/characters are transferred between these nodes, showcasing the SPP profile, which emulates the serial RS232 type of connection.
This application note provides the users with the following functionalities:
The following figure illustrates the PIC18 MCU interface with the RN4678 module. Get the user inputs through the switches available on the PIC18 Explorer Development board, and the on-board LCDs and LEDs monitor the status.
