Turn on SDX-PocketScan and connect to Sodex Mobile App

Updated
TL;DR Turn on the SDX-PocketScan with the white magnet line, attach it to your MagSafe-compatible iPhone, and connect it in Sodex Mobile before you start scanning. Connect the antenna first so the SDX-PocketScan can get stable GNSS positioning.

Summary

The SDX-PocketScan is a compact mobile 3D scanning device for fast and accurate data capture with a compatible iPhone. Before you start scanning, turn on the SDX-PocketScan, connect it to Sodex Mobile, and verify that your setup is ready for GNSS positioning.

Prerequisites

Before you start, make sure you have:

  • An SDX-PocketScan device
  • The antenna correctly plugged into the SDX-PocketScan
  • A MagSafe-compatible iPhone (iPhone 12 Pro or newer except iPhone 17 Pro)
  • The Sodex Mobile App installed, updated, and accessible
  • Access credentials for your correction service provider

Device compatibility The iPhone 17 Pro is not supported because its LiDAR placement prevents correct alignment with the SDX-PocketScan. The iPhone 17 Pro Max is supported when you use the corresponding supported antenna configuration.

Tip Connect the antenna before turning the device on. A loose or missing antenna can reduce GNSS quality and prevent a stable fix.

Step-by-step instructions

Step 1: Check the antenna connection

Make sure the antenna is properly plugged into the SDX-PocketScan before you turn it on. A loose antenna can cause poor GNSS accuracy or connection issues.

Common issue If accuracy values stay high or you cannot reach RTK fix, re-check the antenna connection first.

Step 2: Turn on the SDX-PocketScan

  1. Press the white magnet line once briefly.
  2. Press and hold the white magnet line until the leftmost light at the bottom turns blue.
  3. Wait for the blue light to flash. This shows that the SDX-PocketScan is powered on and ready for pairing.

Tip Make sure the SDX-PocketScan sits flat and centered on the MagSafe area. A stable mounting reduces movement and improves scan consistency.

Step 3: Connect with the app

Optional If you scan frequently, enable automatic connection to the most recently used RTK receiver in Settings. This reduces setup time at the start of a scan session.
  1. Open Settings in Sodex Mobile.
  2. Enable automatic RTK receiver / GNSS connection.
  3. Return to the scan screen and confirm that the RTK receiver tile connects as expected.

Tips and troubleshooting

Reset the SDX-PocketScan

If the SDX-PocketScan is unresponsive or cannot be found reliably, reset it with the small reset hole on the left middle side of the device next to the magnet area.

  • If no device is found during scanning: Make sure Bluetooth is enabled and the SDX-PocketScan is within range.
  • Low accuracy values (>0.1 m): Check the antenna placement, confirm the correction service is connected, and make sure External GNSS is selected in the location settings. Also make sure you have a clear view of the sky and a cellular connection.
  • Device won't power on: Recharge the SDX-PocketScan or check whether you completed the button press sequence correctly.
  1. Locate the small reset hole.
  2. Use a thin tool such as a SIM-ejection pin, needle, or a straightened paper clip.
  3. Carefully press into the hole and hold for 5 seconds.
  4. Release, wait a few seconds, and then try connecting again in Sodex Mobile.
Tip After the reset, keep the SDX-PocketScan close to the phone and make sure Bluetooth is enabled before you reconnect.
