To improve the spatial accuracy of data collected with MobileMap, it may be useful to use an external GPS receiver. There are a wide range of external GPS receivers that can be paired to your Android device to provide the GPS location information used by MobileMap. While the steps may vary with the particular GPS receiver and Android device, the general approach will typically be the same:
Download and install the Bluetooth GPS from the Google Play Store
Enable Mock GPS Provider in Android
Pair the Bluetooth GPS receiver with your Device
As an example of the more detailed procedure, the following steps can be used to pair a Garmin with the tablet, follow these steps:
Download and Install Bluetooth GPS from the Google Play Store (Bluetooth GPS is a third-party application and is not affiliated with Garmin or WSG
Make sure the GLO is turned on
On your Android device, select "Settings" (gear icon on tablet’s home screen), then select "Bluetooth" and enable (slide slider to on)
Under available devices, locate the GLO and select “pair”
Once the GLO is paired, locate the Bluetooth GPS app on the tablet’s home display and launch the application
Check the box to "Enable Mock GPS Provider" within the app
From within the Bluetooth GPS app, press menu (location may vary), then select "Settings"
Under "Service Settings", select the "Reconnect" check box
Under "Connection Problems Related", select the check box for "Use Insecure Connection"
Press the "Back" button on your Android device
From the home screen of the Bluetooth GPS app, select the "Connect" button to the right of the Garmin GLO. If you see data filling up the fields below, then everything is working properly
To test further and ensure that GPS data is being received, select the "Status" and "Map" tabs at the top of the application.
Status: Displays satellite information.
Map: Displays your location on a map.
At this point, the Bluetooth GPS application can be closed and location information should be obtained by MobileMap.

Validating Mock Location activation with your Arrow
In the “Map View” menu of Eos Tools Pro, you will be able to confirm that the Android Location Service is indeed being populated by the Arrow coordinates. But first, you will need to select and then connect to your Arrow receiver. Here is how to proceed:
After you have Bluetooth-paired your Arrow to your Android device, launch Eos Tools Pro. Tap on your Arrow receiver to start the Bluetooth connection (the Arrow Bluetooth LED state should change from blinking to solid at this point).
To validate that your Android device’s Location Service is being populated by the Arrow, navigate to the Map View menu from the Status menu. There you will see two sets of coordinates in two columns: “Device Location” and “Eos receiver”. When the mock location is operating properly with a valid position from your Arrow receiver, coordinate values in both columns will be identical.
