I have a set of DJI FPV goggles but cannot change the Max Power option. It shows on the menu under the device section but I cannot select it.

  • I am in the USA
  • updated to latest firmware: V01.00.0500
  • 2S 3000mAh battery
  • .txt file on sd card narco_pwr.txt with pwr_2 attribute in txt file

  • I have not powered or setup my Caddx Vista.

Max Power is set to 25mW and I cannot change it.

    Have you tried putting a text file called naco.txt in the SD root, containing only the number 1 (to set to US mode?) – Kralc May 24 at 22:30

    I see you state that you have not powered on or setup your Caddx Vista. Is it possible that you can't change these settings unless the goggles are bound to a powered up vista or air unit? I have not personally tested that yet, but that might be your issue. – 5zero7rc May 25 at 4:19
  • @5zero7rc, yes it is possible that the goggles need to bound with the Vista or air unit. But right now I do not have the supplies to test that, and am trying to get verification if this is so. – DroneDome May 25 at 5:26

    @Kralc, I'm in the US, and it has 8ch, so I believe its already in US mode. But yes, I did add the naco.txt file with 1 within the txt file. – DroneDome May 25 at 5:33

You won't know if the "hack" has worked until you also have a Vista or Air unit bound to the goggles.

As a quick test, I powered up my goggles and left everything else off. If I go to where you can adjust the power output it only shows 25mw and is grayed out.

As soon as I power up the rest of the system and the goggles connect to my air unit, I can change power output and other settings. There are a number of options that require the air unit or vista to be powered on before you can change them. I assume that information must be stored on the air unit side, not in the goggles.
