Page 32: Bandwidth
1. The higher rate of bandwidth setting will lead to the higher fluctuation in data waveform. Conversely, the lower rate of bandwidth, data will become more fluent. For example: Bandwidth as 20Hz, Output rate as 10Hz. The waveform is very steady. BWT901CL | manual v0707 | http://wiki.wit-motion.com/english - 32 -... - Page 33 For example, if the bandwidth setting is 20Hz, retrieval rate as 100Hz, there will be 5 repeating data. If you prefer there is no repeating data, it is required to increase the bandwidth more than 100Hz. BWT901CL | manual v0707 | http://wiki.wit-motion.com/english - 33 -...

Page 34: 6-Axis/ 9-Axis Algorithm
9-axis algorithm: Z-axis angle is mainly calculated and analyzed based on the magnetic field. Z-axis angle will have few drift. The default algorithm of BWT901CL is 9-axis. If there is magnetic field interference around installed environment, it is recommended to switch to 6-axis algorithm to detect the angle. -

I just bought a BWT901CL but we cannot discoverit by any phone or laptop.
To connect your WiT BWT901CL sensor to a phone:
1. Install the APK file and grant Location and Storage permissions.
2. Turn on the sensor.
3. Enable Bluetooth on your phone.
4. Search for the sensor; it will initially appear as a MAC address and later as "HC-06" after pairing.
5. Select the device and enter the password "1234."
6. Open the WITMOTION app, choose “9-axis Series,” scan, and select the sensor.
To connect to a laptop, follow similar steps using Bluetooth settings and appropriate software.
