Trimble Setup for iOS Devices

Unearth OnePlace integrates with Trimble R2 and DA2 devices, providing highly accurate data via a wireless Bluetooth connection. As of iOS Version 4.7.3 on the App Store, integrating with the Trimble R2 and DA2 is supported on both phone & tablet. Any other Trimble Devices are not supported.

You will need the Trimble Mobile Manager (TMM) app installed on your iOS device, as well as TMM login credentials in order to connect the Trimble R2 or DA2.

 

Configure and Connect Trimble Mobile Manager -

The first time you connect a Trimble device, you will need to configure your device and connect to the Trimble Mobile Manager. 

 

  • Ensure you have the Trimble Mobile Manager app installed on your phone and that you are logged in on the TMM app.
  • Open the Unearth App and select a project that you’d like to add assets in via Trimble.
  • Open the side menu by clicking the "U" in the top left corner.
  • Tap on “Connect GPS Device”

  • You will now see the “GPS Accuracy” header with the Trimble icon and another header showing “Finding Your Location.”
  • The “Finding Your Location” step can take some time (around 1 min - 5min), and it works best to be outside so the satellites can be found easier.

  • After Unearth finds your location based off the Trimble R2 or DA2, the header will show an accuracy based solely off the Trimble.
  • Tapping on the GPS Accuracy details header will show details from the Trimble R2 or DA2 that are being sent to the device and displayed to the user.

Adding Assets -

Now that the Trimble R2 or DA2 is connected to Unearth, you can begin adding assets.

 

  • Click the "+" button.
  • Select the tool you'd like to add.

  • Click the location arrow to center on location (see center screenshot below).
Since Trimble is based on where you are physically located on the map, you must tap the "Center on Location" button AFTER selecting a tool and BEFORE adding the point to the map to enable the point as a Trimble point. The order of steps is important when adding points from the Trimble's location.

  • Confirm your point was added with Trimble accuracy.
  • The added point should be marked as having been added via Trimble inside the “Geometry” tab on the asset panel. You can determine if a point was added from Trimble if the following are present:
    • Tab states “1/1 points connected with high-accuracy GPS."
    • Trimble icon is located to the left of the point #.
    • An “Accuracy” field is attached to each point.
