How to Get SmartAudio Tramp VTX Control Working in Betaflight 4.1 with VTXTables

Smart Audio and Tramp VTX control are no longer working out of the box in Betaflight 4.1. You now have to configure VTX tables first for your particular video transmitter depending on the protocol it uses.

Why? And What are “VTXTables”?

In the past, everything was pre-configured so you didn’t have to do anything. But starting from Betaflight 4.1, channels and power levels have to be setup manually. You do so by entering a “VTXTable” into the CLI.

Yes, it is annoying and confusing. If you can’t be bothered, just use one of the older BF versions.

You have to know what channels and power levels your VTX supports in order to set it up correctly. And you also have to beware of what frequency and power levels you are allowed to use according to your local regulations. If you break the laws, Betaflight is not responsible as you set it up yourself, I guess it’s one of the reasons for VTXTables.

But looking at the bright side, you do get to keep only your favourite channels, and disabling all the ones you don’t want, making it very customizable.

Copy and Paste into CLI

It would (probably) work for most VTX to just copy and paste one of these VTXTables snippets to the Betaflight CLI. Note that these tables contain all the channels (including the illegal ones in the US).

All you need to know is which VTX control protocol your VTX is using, e.g. Tramp, SmartAudio V1.0, V2.0 or V2.1. Here is a quick guide on how to tell which SmartAudio version you have.

All snippets are copied from this GitHub document, you should read it anyway to learn more about VTXTables: https://github.com/betaflight/betaflight/blob/master/docs/VTX.md#vtx-table

Customize VTXTables for Specific VTX

You can, and you should customize VTXTables for your particular VTX in order for Betaflight VTX control to work properly.

Setting a frequency to 0 will remove that channel – this ensure you don’t accidentally transmit on an illegal frequency, or channels that you don’t want to use.

You can change the powerlevelsnumber (the number of power levels), powervalues (the values of power levels in dB) and powerlabels (the values of power levels in mW) as those are VTX specific values.

I have not tested all of these VTXTables, try it anyway.

I will try to add other popular VTX’s here. Let me know in the comments if we are missing any.

This link has many other VTX too, but they are in JSON file format that you need to download and load in the Video Transmitter tab: https://github.com/Jackjan4/betaflight-vtx-tables

    Yo man some of the Nano vtx’s from eachine have an issue with timing and don’t work with any vtx table. There is a thread on it on the github but yeah figure you or anyone else reading this should know!

    I have a question regarding AKK VTX’s.
    I understand how to set up VTX Tables and such, my question is;
    Do some or all AKK boards that use SmartAudio 2.0 and the power level selection process using 0, 1, 2, 3 as the values to select from four power levels, for instance, use the value 0 (zero) to select Pit Mode?
    I ask this because my AKK board has four power output levels, I set it up expecting 0 (zero) to select 25mW. When 25mW was extremely under powered, I thought that I had received a faulty VTX. Recently a person mentioned to me, whilst taking about somebody else’s VTX setup, that 0 (zero) selects Pit Mode in Race VTX’s… I didn’t get to discuss anymore. It opened up the question in my mind of whether AKK use the values 0, 1, 2, 3, 4 for a four power output VTX?
    0 (zero) for Pit Mode and 1, 2, 3, 4 for the four power levels?

    I notice some people question the AKK power labels.
    Asking if 120 should be 1200 or 1.2
    The Power Labels are just that, Labels.
    More precisely; three character labels.
    That’s why 120 probably cropped up. 1200 will of been input somewhere, maybe a CLI paste and one off the zeros got clipped because that label can only hold three characters.
    So; 1.2 is the best way to label 1200mW.

    Hey Oscar.
    I also noticed that for AKK vtx power you providing this values: 25, 200, 600, 120 .. is that correct? As far I understand betaflight description it shouldn’t be 1.2 for 1200mw.. I set my as 1.2 and it feels like it’s not as strong signal as before on BF4.0.. I’m flying the same quad in the same park but noticed weaker video signal.. am I wrong with setting my value as 1.2 ? Should I put 120?

    Thanks Oscar alway provide an usefull information.
    i have Iflight succes Mini VTX set all good.
    I’ll be able to change channel and frequency,butvthe powet output is not the coreect 1,even we chosoo 500mw on BF when check on osd in th Tramp Protocol only show 25MW and can’t be change through OSD.
    Only manage to get it work that change manually by Button.
    Any 1 experience this before.

    TAKE CARE, I Thing there is a Bug with eachine VTX. Yes, you can change the channel, but in differentes models , the power output change at the same time to the 25mw.

    With tx805 and TD600 only with beta 4.1

    Any sugerencias suggestion?

    Great source of information as always. I wish to point out AKK code “vtxtable powerlabels 25 200 600 120”. Should not be “1200” instead of “120” ?

    For the life of me, I can’t get my 5.8G SucceX Mini 500mW VTX set up on 4.1. I used a VTX table that I made and it seems to work in the configurator. I can change settings and they seem to take effect, but though the OSD it’s all dashes, and nothing saves. Any idea what I’m doing wrong?

    Great resource – thanks. Any intel on how pit mode works? I have a TBS Nano and when I move the slider in the confi page, it does not ‘stick’ and turn off.
