The MAXREFDES100# Health Sensor Platform board features a Bluetooth Low Energy (BLE) radio, not Classic Bluetooth. With this board, the ECG and accelerometer generate a significant amount of data. The intended use case is to collect data from the multiple sensors, then process onboard with an algorithm and then transmit a short message such as heart rate through BLE. However, during algorithm development large datasets from the sensors are needed. This is best done via a wired connection (USB). It is obviously a hassle being tethered, but you can collect so much more data. Many people process this data in a program such as MatLab. This is the best approach for development. Our recommendation is to read the ECG, filter/process the data locally, then only transmit one screen worth of the waveform. Then repeat this process as needed.
