Setup Trimble R1 On An Android Device

These instructions are applicable for most Trimble Bluetooth devices including the R1, R2, TDC 150, and Catalyst.  The word "phone" in the instructions below refers to any Android based phone or tablet.

First Time Setup
1. Power on your R1.

2. Open your Bluetooth settings on your phone.  Enable Bluetooth.  Select the R1 from the list of nearby devices to cause your phone to "pair" with the R1. It usually shows up as "GNSS" 

3. Download and install the Trimble Mobile Manager app (TMM) from the Google store.

4. When you first run TMM it will prompt you to login with your Trimble credentials.  If you don't already have a Trimble login, click the link to create a free account.

5. After logging in to TMM, click the menu button and choose "Position Source".  Change the GNSS receiver type to Bluetooth and click "List connected devices", Select your R1 from the list

6. Back to the TMM menu, click Application Settings, and turn on "Share Location"

7. On your phone's Settings screen select "Developer Options".  If you don't see Developer Options on your Settings menu then you may have to enable this option by doing the following: Go to Settings > About > Software Info.  Locate the "Build Number" and tap it 7 times. Now you should see "Developer Options" on your main Settings screen.  Select this new option.

8. On the Developer Options screen click on "Select mock location app".  Select the Trimble Mobile Manager app in the list.  Note: If using a Trimble TDC 150, this mock location app may be defaulted to an app called "Space".  You may need to completely uninstall the Space app before selecting TMM.

Each Time you start your day
9. Power on the R1

10. Launch the TMM app, and switch the slider next to the name of your R1 to ON.

11.  Log into Diamond Maps in your browser and click the GPS button on the right side of the screen.  If prompted, indicate that you allow Diamond Maps to access your location.
12.  To test your connection, go outside and place the R1 on the ground.  Walk about 20 feet in one direction with your phone while looking at the Diamond Maps display.  If you are successfully connected to the R1 then the location should not move.  As  a second test, hold you phone in one place while you move the R1 an arm's length to your left and then to the right while holding the phone stationary.  The point should move slightly on the map display

Offline App
The R1 can also be used with the Diamond Maps Offline app.  See here for setup instructions.  While the offline app is not as functional, it is a lot easier to setup for GPS and it records more information with each GPS point you mark.

Additional Notes
  • Older instructions referred to the "GNSS Status" app which has been replaced by the newer "Trimble Mobile Manager" app.
  • If you get an error indicating something like "user denied" or if it does nothing then read here for instructions on setting your device's permissions.
  • Click Here for more GPS setup instructions
  • Some phone and tablet operating systems will never report an accuracy better than 10 feet or more despite the fact that you are receiving a high accuracy position from the GPS.  If you have performed the test in step 7 above to confirm that you are in-fact tracking the R1 and not your phone/tablet's on-board GPS then you should ignore this mis-reported accuracy value.
