Device Compatibility Check

In this section

This section explains how to use the Check azimuth, elevation feature to see if your smartphone supports UWB-based direction detection (Azimuth and Elevation). In GrowSpace mobile app testing, angle detection support is directly related to RTLS accuracy. So it’s important to check this in advance.

Feature Overview

The Check azimuth, elevation menu is a diagnostic tool for Android devices. It helps you check whether your smartphone supports UWB-based angle measurement.

  • On iOS devices, angle detection is usually enabled by default.

  • It works automatically with the RTLS features, so no separate menu is needed.

  • This feature is only available on Android, and iPhone users do not need to check it manually.

Main Use Cases

  • Check if your Android device supports angle detection

  • Test detection performance under different distance and direction conditions

  • Evaluate if angle-based correction can improve RTLS positioning accuracy

How to Use

  1. Launch the GrowSpace mobile app.

  2. On the main screen, select Check azimuth, elevation.

  3. If a powered N1 Anchor is nearby, it will be detected and connected automatically.

  4. Once connected, the following information will be shown in real time:

    • Distance (m)

    • Azimuth (°)

    • Elevation (°)

Detection performance may vary depending on your smartphone model, sensor quality, UWB firmware, and indoor space layout.

Platform and Device Compatibility

Android Devices

  • On most Galaxy S series devices, only the Plus (+) or Ultra models support UWB-based angle detection.

  • Some models from the Google Pixel series also support this feature.

  • You should use the Check azimuth, elevation menu to verify if your device supports angle measurement.

Recommended Android models:

  • Galaxy Note20 Ultra

  • Galaxy S21+ / S21 Ultra

  • Galaxy S22+ / S22 Ultra

  • Galaxy S23+ / S23 Ultra

  • Galaxy S24+ / S24 Ultra

  • Galaxy S25+ (and future models)

  • Galaxy Z Fold2 ~ Z Fold5

  • Selected Pixel UWB models

⚠️ For Galaxy S24+, angle detection may be limited. We recommend testing in advance.

iOS Devices

  • Most iPhone models from iPhone 11 and up have built-in UWB angle detection.

  • This means azimuth and elevation data are used automatically during RTLS measurements, without the need for a Check azimuth, elevation menu.

  • As a result, this menu is not shown in the iOS app.

Recommended iPhone models

  • iPhone 11 / 11 Pro / 11 Pro Max

  • iPhone 12 ~ 16 series(including Pro models)

Notes

  • Whether angle detection works depends on three factors: the built-in UWB chipset, motion sensors, and OS-level permissions.

  • Results may vary depending on test conditions such as anchor spacing, signal reflection, and power stability.

  • To improve RTLS accuracy, a correction algorithm that considers both distance and angle information may be applied.
