DJI FPV System New Updates

06 Jan 2023

• New firmware are available for the following devices:

• DJI O3 Air Unit Firmware: V01.02.0000
• DJI FPV Goggles V2 Firmware: V01.06.0000
• DJI Goggles 2 Firmware: V01.04.0000
• Remote Controller Firmware: V02.00.0500

What’s New?

• Added support for the DJI O3 Air Unit to record video at 4K@30fps, 2.7K@30fps, and 1080p@30fps. When used with DJI Goggles 2, 4K@120fps, 2.7K@120fps, and 1080p@120fps are also supported.
• Added ability to set the sharpness and noise reduction value. Go to Settings, Camera, Advanced Camera Settings in the goggles menu to set the value (I tested these values here)
• The time for DJI O3 Air Unit to enter low-power state after stopping the aircraft motors has been changed from three seconds to six seconds.
• Improved D-Cinelike to 10bit, providing more possibilities for post-processing.
• Optimized the camera exposure in some backlighting scenarios to avoid over-dark in shadow areas.
• Optimized the remote controller signal in some scenarios.

Notes:

• Restart DJI O3 Air Unit, the remote controller, and goggles after the update is complete.
• If update fails, restart DJI O3 Air Unit and DJI Assistant 2 (Consumer Drones Series), then try again.

How to Update?

• For Goggles 2 and O3 AU, connect them to DJI Assistant 2 (Consumer Drones Series).
• For Goggles V2, if you previously rooted and installed WTFOS, you need to uninstall WTFOS first as shown here: https://oscarliang.com/fpv-wtf-root-hack-dji/#How-To-Update-DJI-Firmware-After-Rooting. Your goggles are still rooted (it’s permanently) so you can always roll back and install WTFOS again if you want. Don’t worry. If you previously installed updates to work with O3 AU, then you can go ahead and update in DJI Assistant 2 (Consumer Drones Series).
