# Internet connection using another device

This feature is not supported if the controller is running Android. To connect a controller running Android to the internet you must use a Wi-Fi or cellular connection on the controller, or use Bluetooth internet tethering. See Internet connection setup and Internet setup using a separate smartphone.

If you have another device such as a GNSS receiver or a mobile phone, you can connect the controller to the internet through that device. This is especially useful for an RTK internet data link if the SIM card you want to use is in the receiver or if you want to be able to use the internet on the controller for other functions during the RTK survey.

To connect to the internet through a receiver or a mobile phone:

- The modem in the device must support the Bluetooth DUN service.

- The receiver must be an older Trimble receiver, such as the R10-1 or R8s.

- Modems used with Trimble Access must support Hayes compatible AT commands.

To configure the connection:

1. In Trimble Access, tap and select Settings/ Survey styles.
2. In the Rover data link or Base data link screen of the survey style, select Internet connection from the Type field.
3. Tap next to the GNSS internet source field to open the GNSS internet source screen.
4. Tap Add. The Create new GNSS internet source screen appears.
   1. Enter a Name for the GNSS internet source.
   2. If you have not yet connected the controller to the device, you can do it now:
      1. Tap Config. The Windows Bluetooth settings screen opens.
      2. Make sure Bluetooth is set to On. and then tap Add Bluetooth or other device.
      3. Select Bluetooth as the device type. In the list of devices on the controller, select the name of your phone.

      4. When prompted, tap OK or Connect on each device to confirm the passkey is correct.

         If there is a long list of Bluetooth devices on the controller, swipe down (scroll) to see the passkey confirmation prompt and buttons. The prompt times out after a few seconds, so if you miss it, tap Cancel and repeat steps (c) and (d).

      5. On the controller, tap Done.
      6. Return to the Create new GNSS internet source screen and configure the connection settings for the connected modem.
   3. In the Bluetooth modem field, select the device the controller is connected to.

   4. In the APN field, tap to choose the method for selecting the Access Point Name (APN) for the internet service provider. This is the service provider that provided the SIM card in the device:

      - Choose SIM default to load the APN profile directly from the SIM card in the device.

      - Choose Select Access Point Name (APN) to select your Location and your Provider and plan from the APN wizard in Trimble Access. Tap Accept.

      - Choose Load from modem to connect to the receiver and load the APN information from the modem in the connected receiver. The Load from modem option is available only if the receiver has firmware version 5.50 or later installed.

   5. In the Number to dial field, enter *99***1#. The *99***1# is a standard access code for mobile internet. If you are unable to connect using *99***1#, contact your mobile internet provider.
   6. If required, enter a Username and Password. By default these fields are both set to guest

   7. Tap Accept.

      If a message appears warning that details of the Bluetooth DUN service for the connected device could not be resolved, then the device may not support Bluetooth DUN. Try connecting creating a connection to the phone using the steps for a smartphone.

5. In the GNSS internet source screen:
   1. Select the GNSS internet source you just created.
   2. If a PIN is required, enter the PIN in the Modem pin field.
   3. Tap Accept.

   The GNSS internet source you just created is shown in the GNSS internet source field in the Rover data link or Base data link screen of the survey style.

6. Configure the GNSS correction source settings in the survey style as required. See To configure a rover internet data link or To configure a base internet data link.
