Arduino Nano 33 BLE Sense and a Pulse Oximeter (MAX30102) sensor. The objective is to measure and transmit pulse and oxygen saturation data using Bluetooth Low Energy (BLE). The system is running on MicroPython. I have checked that the I2C connection and initialization for the MAX30102 sensor is okay, confirmed the BLE initialization and advertising settings, tested BLE connection with a mobile app to ensure proper pairing.
