Bluetooth service implementation for the Arduino Nano 33 BLE and Nano 33 BLE Sense.

What does this sketch do?

This sketch implements a Bluetooth Low Energy (BLE) service which makes it easy to listen to data from one or more sensors on a Arduino Nano 33 BLE and Nano 33 BLE Sense. The sketch utilizes the on-board sensors and Bluetooth Low Energy connectivity.

See the BLE Specification for service implementations details (services and characteristics).

Supported inertial measurement unit (IMU) sensors found on both the Nano 33 BLE and Nano 33 BLE Sense:

• Accelerometer (LSM9DS1)
• Gyroscope (LSM9DS1)
• Magnetometer (LSM9DS1)

Supported sensors found on the Nano 33 BLE Sense only:

• Digital microphone (MP34DT05)
• Temperature (HTS221)
• Relative humidity (HTS221)
• Pressure (LPS22HB)
• Gesture sensor (APDS9960)
• Ambient light (APDS9960)
• Color (APDS9960)
• Proximity (APDS9960)

The library uses the following filters and algorithms related to the IMU sensors:

• Arduino's Madgwick AHRS sensor fusion algorithm implementation for orientation (heading, pitch, and roll)

Libraries

The following libraries are compatible with the Bluetooth service implementation provided by this sketch:

• Node.js interface (npm module): @vliegwerk/arduino-nano-33-ble
