• Maintain a stable power source during the linking process.

• Goggle and Betaflight protocols must match (e.g., SBUS_FAST on both ends).

Preparation

1. Fully charge all devices.

2. Power on the DJI Goggles, DJI Air Unit, and DJI FPV Remote Controller.

3. Wait about 10 seconds for all systems to initialize.

Step 1 – Bind Goggles with Air Unit

1. On the DJI Goggles, open:
   Status > Switch > Select your Air Unit

2. Press the Link button on your DJI Goggles

3. Press the Link button on the DJI Air Unit (small button next to the status LED).

4. The LED will blink and turn solid once the link is complete.
   The camera image will appear in the Goggles.

Step 2 – Bind Remote Controller

1. Press and hold the Link button on the DJI FPV Remote Controller until the LEDs start blinking.

2. After a few seconds, the connection is established.

Step 3 – Betaflight Configuration

1. Open the Betaflight Configurator → CLI tab.

2. Enter the following commands:

   1set sbus_baud_fast = on
   2save
   3
   

3. Make sure the Goggles protocol is also set to FAST.
   (Default: sbus_baud_fast = off, Goggles protocol = NORMAL)

Final Check

• The camera image should now be visible in the Goggles.

• The controller should control the aircraft correctly.

• If not, verify that both protocol settings match.
