Connecting to the DA2

On an Android device, you can connect directly to the DA2 receiver from any supported Trimble field software. Refer to the documentation for your field software.

If you are using the DA2 with a third-party app, then connect to the DA2 receiver from the Trimble Mobile Manager app:

1. Make sure Bluetooth is enabled on your Android device.

2. Press the power button on the DA2 until the LED starts blinking blue. This indicates it can be discovered by a nearby Bluetooth device.

3. In Trimble Mobile Manager, tap and tap Position Source. In the GNSS receiver type field, select Bluetooth Receiver and then tap List Connected Devices.

4. The device scans for nearby devices. Receivers are listed by model name and serial number. If you are not sure which receiver is yours, check the serial number label on the underside of the receiver.

5. If the receiver is not listed, tap the Refresh icon to rescan. If there are a number of Bluetooth devices in the vicinity you may need to refresh the list a couple of times.

6. Select the receiver to connect to.

   In the Trimble Mobile Manager Home screen, enable the Position Source switch to connect the software to the receiver. The Home screen shows the name and serial number of the connected receiver.

On an iOS device, you must first connect the device to the DA2 from the iOS Bluetooth settings screen, and then connect to the DA2 from the field software.

1. Make sure Bluetooth is enabled on your iOS device.

2. Press the power button on the DA2 until the LED starts blinking blue. This indicates it can be discovered by a nearby Bluetooth device.

3. Go to the iOS Bluetooth settings screen on your device.

4. Search for your DA2 in the MY DEVICES or OTHER DEVICES section. It will be recognizable with the string DA2 [61XXXXXXXX]: Trimble. If you are not sure which receiver is yours, check the serial number label on the underside of the receiver.

5. If the receiver is not listed, tap the Refresh icon to rescan. If there are a number of Bluetooth devices in the vicinity you may need to refresh the list a couple of times.

6. Tap on the device name to connect. DA2 will connect with your device.

   Once connected, the DA2 will appear in your MY DEVICES list, and will flagged as connected. The LED will change from blinking blue to solid blue to confirm that you are connected to your iOS device.

7. In Trimble Mobile Manager, tap and tap Position Source. Select the receiver your device is connected to.

8. In the Trimble Mobile Manager Home screen, enable the Position Source switch to connect the software to the receiver. The Home screen shows the name and serial number of the connected receiver.

In the event of a Bluetooth connection issue, you may need to remove an existing pairing between your DA2 and your Android or iOS device. This is called “forgetting a device”.

To forget a Bluetooth device:

1. Open the Bluetooth settings on your Android or iOS device.

2. Search for the DA2 receiver serial number.

3. Tap Forget this device (or similar, depending on your device type)

   Your device will remove any previous pairing/connection data.

For more information on removing existing Bluetooth connections, refer to the documentation for your Android or iOS device.

You can also make DA2 forget any previously paired Android or iOS devices by resetting it.

To reset the DA2:

1. Make sure the DA2 is powered on.

2. Press-hold the Power button for approximately ten (10) seconds.

   The LED will flash quickly then the DA2 will turn off. It will forget any previously paired devices.

3. Press the Power button again to power on the receiver.
