Video Transmitter Tab

Configure the video transmitter (VTX) using this tab. It allows setting of the power, band, channels, etc.

note

When using a DJI or Walksnail video transmitters, this tab can be ignored. This is only used for analog and HDZero video transmitters.

VTX tab

It is important to have VTX Telemetry (SmartAudio or Tramp) enabled in the Ports tab to use this feature.

Selected Mode

OptionDescription
Enter frequency directlyWhen enabled, the Configurator will send a frequency value in place of the habitual band/channel. For this to work the VTX must support this feature.
BandSelect the band to use.
ChannelSelect the channel to use.
PowerSelect the power level to use.
Pit ModeWhen enabled, the VTX enters in a very low power mode to let the quad be on at the bench without disturbing other pilots. Usually the range of this mode is less than 5m.
NOTE: Some protocols, like SmartAudio, can't enable Pit Mode via software after power-up.
Pit Mode frequencySelect the frequency to use in Pit Mode.
Low Power DisarmWhen enabled, the VTX uses the lowest available power when disarmed (except if a failsafe has occurred).
  • On - Go to lowest power possible when disarmed
  • Off - Always on the set power level
  • On until first arm - Stay on the lowest power possible until the first time the quad is armed, then go to the set power and stay there indefinitely
  • Current Values

    OptionDescription
    Device readyIndicates if the Flight Controller is talking to the VTX.
    VTX TypeThe type of telemetry that is used to communicate with the VTX.
    BandThe current band that the VTX is set to.
    ChannelThe current channel that the VTX is set to.
    FrequencyThe current frequency that the VTX is set to.
    PowerThe current power level that the VTX is set to.
    Pit ModeIndicates if the VTX is in Pit Mode.
    Pit Mode frequencyThe frequency that the VTX is set to when in Pit Mode.
    Low Power DisarmIndicates if the VTX is in Low Power Disarm mode.

    VTX Table

    OptionDescription
    Number of bandsThe number of bands that the VTX supports.
    Number of channels by bandThe number of channels that the VTX supports.
    Name, Letter, FrequenciesThis table represents all the frequencies that can be used for the craft's VTX. It's possible to have several bands and for each band it is required to configure:
  • Name - The name of the band, like BOSCAM_A, FATSHARK or RACEBAND.
  • Letter - Short letter that references the band.
  • Factory - This indicates if it is a factory band. If enabled Betaflight sends to the VTX a band and channel number. The VTX will then use its built-in frequency table and the frequencies configured here are only to show the value in the OSD and other places. If it is not enabled, then Betaflight will send to the VTX the real frequency configured here.
  • Frequencies - Frequencies for this band.
  • Remember that not all frequencies are legal in all regions.
    Number of power levelsThe number of power levels that the VTX supports.
    Power levelsThis table represents the different values of power that can be used for the VTX. They are divided into two:
  • Value - each power level requires a value that is defined by the hardware manufacturer. Ask the manufacturer for the correct value or consult the Betaflight wiki of VTX Tables to grab some samples.
  • Label - put here the label for each power level value. It can be numbers (25, 200, 600, 1.2), letters (OFF, MIN, MAX) or a mix of them.
  • Bottom Bar

    OptionDescription
    SaveSave the changes to the Flight Controller
    Save to fileSave the VTX settings to a JSON File
    Load from fileLoad the VTX settings from a JSON File
    Load from clipboardLoad the VTX settings from the clipboard. Has to be a valid JSON.
    Save Lua ScriptThe 'Save Lua Script' button will allow to save a mcuid.lua file containing the VTX table configuration that can be used with the Betaflight TX Lua Scripts. Version 1.6.0 and above can use the file as is, but for older versions of the scripts it should be renamed to match the model name on the TX.
