Finding the Bluetooth address on the instrument
To connect an LPS instrument to 3D-MC with LongLink, you will need to find the MAC address (BD ADDR) of the instrument. This 12-character ID is unique to each instrument and must be entered into the 3D-MC machine builder.
- To find the instrument's Bluetooth address, you will need to navigate to the Comms screen of the instrument.
- For this example, a GT total station is being used. To find the Comms menu on the GT, go to Config > 4. Comms > 4. Bluetooth

- In the Bluetooth menu, tap on the blue Info button at the bottom of the screen.
- This should give you the MAC address (BD ADDR). Make note of this code exactly as it appears on the instrument.

Entering the Bluetooth address in 3D-MC
- Once you have the BD ADDR, you will need to enter that address into the machine builder in 3D-MC.
- In 3D-MC, edit the machine builder for the LPS machine by going to Control > Machine Setup
- Highlight the machine builder and tap the Edit button.

- Navigate to the LPS Connection screen and enter the BD ADDR MAC address.
- No Passkey is typically required, so leave it at 0000.
- Hit Next until the machine builder is finished.

- The instrument should connect.
- If the instrument does not connect within 10-15 seconds, ensure Bluetooth comm settings of the instrument are correct and the MAC address was correctly entered in 3D-MC.
