Why we can't stream data above the frequency of 120Hz with metawear? I 'm asking this because there is a new product in the market (I will not name it for obvious reasons) that can stream data (BLE 5.0) up to 5 sensors at 60Hz.
Bluetooth is not that fast. With all the packet overhead and sensor data, you typically get about 120Hz out.
If you "pack the data", which means less overhead and more data in a single packet, you can get around 200Hz.
