SAMPLING RATE (USB)*
▶ Inertial sensors ≤ 100 Hz
Accelerometer, Gyroscope, Magnetometer
▶ Environmental sensors ≤ 1 Hz
Temperature sensor, Humidity sensor, Air pressure sensor, Light sensor, Microphone
* Inertial sensor special mode: 2kHz streaming Accelerometer (without Gyroscope,
Magnetometer and environmental data)
Hints: BLE sampling rate depends on the quality of the BLE connection; Microphone data can only be
transferred via BLE.
INTERFACE
▶ USB communication protocol
▶ Bluetooth Low Energy communication protocol
