Is the acceleration measured along the x, y, and z axes referenced to the device itself or to gravity?

The product measures acceleration along the axes indicated by its markings; the measured acceleration value corresponds to the acceleration along that specific axis. Accelerometer calibration establishes a reference coordinate system for the product; following horizontal calibration, the measured angles are referenced to the horizontal plane.

Connected four additional devices, but the 3D orientation keeps spinning erratically?

When multiple devices are connected, opening the 3D view displays the visualization for only one of them; you cannot have multiple 3D view windows open simultaneously.

You modified the data transmission rate and bandwidth in the app, but they reverted to the default 10Hz after a power cycle?

The modification was actually successful; however, the device does not read these specific rate and bandwidth settings upon restarting. Although the change took effect, the displayed values ​​do not match the modified parameters. You can verify whether the modification was successful using the PC software.

What do the different Bluetooth indicator light states mean?

Charging while powered on: The red light stays solid; it turns off once fully charged.
Operation while powered on: The blue light flashes rapidly during connection and flashes slowly once connected.
Powered off: The indicator light is off.
In the event of a malfunction: The red light turns on during charging, but the blue light fails to turn on when powered up, or no lights turn on at all.

Why is the Z-axis angle inaccurate?

*6-axis products or 6-axis algorithms:** With our Kalman filtering applied, the X and Y axes exhibit no angular drift. While the Z-axis shows no drift when stationary, cumulative errors occur during movement. Since the Z-axis angle is calculated by integrating angular velocity without an external reference for filtering, drift is inevitable; in contrast, the X and Y axes utilize gravity field filtering, preventing drift. Consequently, the Z-axis relies on relative measurements over short intervals—calculating the rotation angle based on the difference between consecutive readings. This requires periodically sending a Z-axis zeroing command; please refer to Point 5 or the communication protocol for specific command details.
2. **Inaccuracy with 9-axis algorithms:** In 9-axis mode, the Z-axis angle is derived from magnetic field analysis. The sensor is susceptible to magnetic interference from nearby objects containing iron, nickel, or cobalt, which can compromise accuracy. Installation should aim to avoid such interference. While magnetic field calibration can correct for minor interference, please note that products are factory-calibrated within magnetic shielding enclosures; generally, we do not recommend recalibrating for magnetic fields—simply avoiding interference sources allows for direct use.
*Note:* If long-term Z-axis angle tracking is required, a 9-axis sensor is recommended. If only the Z-axis angle is needed for use in a planar environment, the HWT101 is a suitable choice.
