    Bump for this video in 2021 - at around the 8 minute mark setting the SBUS rate to FAST saved me from buying a new Air Unit, I didn't know what to search for before but if your DJI Tx is not 'talking' to BetaFlight, double check that Tx is set to FAST (using goggles) and Rx is set to FAST using BetaFlight CLI shown at about 8 minutes in this video. Thank you Joshua!

    Thank you so much ! My Geprc Rocket Plus dropped 100" upside down onto the asphalt and dented the air unit (doa), broke all props, and destroyed the prop guards. I had accidentally bumped it from acro to angle mode and it always drops to the ground. Wrote dji to ask if that normally happens. They did not say and had my send them an export file for them to analys. Waiting to hear back. Well, I bought a new air unit and installed it. It would bind, but no controlling to the FC. Did the get abus_baud_fast = ON and it works now !!! :-)

    I saw another video that indicated the DJI protocol would be in the pull down menus for 4.1, but that does not seem to be the case. The iFlight controller came preconfigure, maybe I need to flash it again to make sure it really has the latest 4.1 ?

    Hi Joshua, I'd like to use the Kakute F7 FC for my DJI build (not the HDV as I already have the original F7). I will only be using 3s and 4s Batteries. My understanding from the manual (it's rumored that you helped to create it), is the I will need to use the GND and B+ pads to power the air unit to get the correct voltage. Also, looks like the yellow DJI HDL (S-Bus) wire will go to R6. The UART RX (OSD) and UART TX (OSD) wires will need to go to an open UART on the board (RX to TX and TX to RX). My question here is can I use the same UART, or do I need separate ones? Also, are my assumptions above correct for the power and SBUS connections? Thanks in advance.

    • @JoshuaBardwell
      @JoshuaBardwell  5 лет назад

      All correct.

    Hi Joshua, you said in this video that your jb f4 fc with 9v voltage regulator is not good enough to power up the air unit. But your fc manual states that it can deal 9v * max 1.2A equals 10.8W. the specs on the dji website of the air unit states that input power varies between 7.4-17.6V and 4-9W. Wouldn't your JB f4 fc voltage regulator suffice after all to power up both the air unit and camera? Love your videos. Keep up good work!

    Hi Josh, thanks for your informative build tutorial. I have sort of related/unrelated query about the DJI system. I realize it's a 'proprietary/close end system but am wondering if it were possible to hack the transmitter (probably would be illegal to say the least) and send the signal to a third-party receiver/monitor....completely by-passing the goggles? I know the goggles have a usb-c but as far as I understand, it's not a A/V output. I'm hoping DJI will allow something like this in the future firmware updates but for the moment I don't think it's possible. Someone mentioned you can rent a box for viewing the live feed but know any details on that. The reason I'm asking this question is because I'd like to mount the 'air unit/camera' on an older Inspire 1 to be used as a high quality HD FPV viewing source. thanks.

    • @JoshuaBardwell

    @RCOverKill 5 лет назад

    I got a totally off question, but dont know who else to ask. Can I use another uart for sbus, rather can another uart be inverted through the cli?

    • @JoshuaBardwell
      @JoshuaBardwell  5 лет назад +1

      On an F4-based flight controller, UARTs cannot be inverted through the CLI. There must be a hardware inverter installed on the board, which is why there is a dedicated SBUS pad on the FC (that's the pad with the hardware inverter). On an F7-based flight controller, all UARTS support inversion and you can connect SBUS to any UART you prefer, although the manufacturer may have placed the pads with the intent of a certain UART being used for receiver.
      If you need to put SBUS to a different UART (like because you lifted the SBUS pad) then the workaround is to do the "uninvert hack" on the receiver. This gets un-inverted SBUS from the receiver and you can connect it to any UART RX pad you want. If you do the "uninvert hack" then you must go to the CLI and type:
      set serialrx_inverted=on
      save

    that write on the description of the FC "Filtered voltage output for clean, noise-free video. 2 On-board regulators output 5V and 8V. 5V output up to 1.5A to power peripherals such as receiver, FPV camera, or LED strip. 8V output up to 2A to DJI FPV VTx."

      The air unit takes between 2s and 4s voltage, so you'll have to get a voltage regulator to step down your 6s voltage to somewhere between 2 and 4s. At that point, you should be able to use whatever battery you want. I built mine using the Hobbywing G3 stack which has a built-in 12v pad.

    Chose Sbus / speksat receiver.
    TX is green ( conn) and Goggles have video. Also battery info.
    Can control the motors. With sliders
    BUT no TX toRX controls.
    Have heard about CLI set Sbus fast. Tried both. Of normal.
    Also changed in Goggles.
    BUT maybe i do something wrong in this procedure.

      @@JoshuaBardwell hi Joshua, maybe do u know now I can not use dshot1200 it isn't listed, but my FC is Mamba F722s (does support 1200), how to fix that? Thank you.
      UPD: I found
      Update (Sep 2019): DShot1200 is officially removed from Betaflight 4.1 as it no longer supports 32K looptime and the developers believe it brings no benefit under 8K looptime compared to DShot600.
