· User configurable switch (SW2)
In the Idle state, the level of the reset switch is pulled high using external pull up resistor and, when the switch is pressed, it drives the level of the switch to low.
User configurable switch is also pulled high using external pull up resistor and when the switch is pressed it drives pin low.

3.7 LEDs
One user-programmable blue indicator LED (D5) is available on the WBZ451 Curiosity Board and this LED can be turned ON or OFF using the connected GPIO pin PB7. Drive the pin to high level to turn OFF the LED and drive the pin to low level to turn ON the LED.
Important: PB7 is also SWO pin on the WBZ451 module. During a programming/debug session with MPLABx IDE this pin is always driven low from the WBZ451 module, thus making the user LED turned ON entire DEBUG session. When DEBUG session is exited, this pin operates normally.

3.8 Temperature Sensor
Analog output from the temperature sensor (2.3V-5.5V Microchip MCP9700A, U3) is connected to one of the analog pins (PB6, AN2) of the module's ADC channel.

3.9 QSPI Serial Flash
The WBZ451 Curiosity Board has an on-board 64-Mb, 2.3-3.6V Serial Quad I/O (SQI) Flash ( SST26VF064B, U6) memory for storage of data. SST26VF064B default at power-up is with WP# and HOLD pins enabled and SIO2 and SIO3 pins disabled allowing for SPI protocol operations without register configuration. Register configuration is required to switch to Quad I/O operation with QSPI.

4. Getting Started
4.1 Introduction
The BLE sensor application is an excellent demonstration of one of the many real-world Bluetooth Low Energy (BLE) applications involving monitor and control of sensor, lights and so on, wirelessly. This application brings BLE concepts like advertisements and connection establishment to practice. The demo consists of the WBZ451 Curiosity Board with accompanying BLE firmware, the Microchip Bluetooth Data (MBD) smartphone application. The MBD application has the capability to scan for BLE advertisements from WBZ451 module and to establish a connection. Scan operation monitors temperature sensor and status of RGB LED (ON or OFF). Establishing a BLE connection with WBZ451 module enables users to control the RGB status (ON or OFF) as well as intensity and color of the RGB LED using slide controls.
4.2 BLE Sensor Application Demo

3.2. The user programmable blue LED starts blinking on Curiosity Board when the board is in advertisement mode.
4. Monitoring RGB LED state and temperature as follows: 4.1. WBZ451 Curiosity Board starts in advertisement mode to advertise its presence to a smartphone and to allow access to RGB LED ON or OFF state and temperature sensor data. 4.2. Navigate through the smartphone application as shown in the following figure to access the advertisement information. Figure 4-1.MBD Smartphone Application

5. Controlling RGB LED state ON or OFF as well as intensity and color as follows: 5.1. Click the device that shows up after initiating a scan to establish a connection with WBZ451 module.
