For those who’re new to Betaflight Configurator, take a look at this tutorial: https://oscarliang.com/betaflight-firmware-setup/

Find out how to Use Betaflight CLI

You’ll be able to kind instructions within the textual content enter area on the backside of the display and press Enter to execute them.

Sometimes, a command follows this construction:

[command] [setting] = [value]

For instance, to disable RC smoothing:

set rc_smoothing = OFF

save

After altering a setting, you could kind save to use it. The flight controller will reboot instantly after saving.

For those who exit the CLI with out saving, your modifications shall be misplaced.

To exit the CLI with out saving settings, you’ll be able to

• Enter the command exit
• Or, click on on one other tab
• Or, click on the top-right “disconnect” button

CLI Syntax Fundamentals

The syntax in Betaflight CLI is easy and beginner-friendly.

Not Case Delicate

Instructions are case insensitive in CLI, you’ll be able to kind instructions in any case you need, massive letters, small letters, don’t matter, the entire following work the identical:

set serialrx_inverted = on
SET SERIALRX_INVERTED = ON
seT serialRX_inverTED = oN

Areas Don’t Matter

set serialrx_inverted = on
set serialrx_inverted=on
set serialrx_inverted =on
set serialrx_inverted =         on

Primary CLI Instructions You Should Know

assist – Listing All Instructions

assist

This exhibits each accessible CLI command.

Use this when:

• You don’t know what instructions exist
• You’re exploring new options

standing – Test FC System Data

standing

This is likely one of the most essential instructions.

It exhibits:

• CPU kind (F4, F7, H7, and so on.) and clock pace
• Accessible sensors (gyroscope, accelerometer, barometer, magnetometer, GPS, and so on.)
• Flash reminiscence
• Firmware construct key (helpful for checking construct choices)
• System data resembling CPU load, voltage, gyro fee, and so on.

Use this for fast diagnostics, particularly if one thing isn’t working (e.g., gyro lacking).

get – View Settings

get

You need to use this to seek for particular settings, which is particularly helpful for those who don’t have them memorized:

get gps

And if I wish to verify Turtle mode associated settings (Flip Over After Crash), I kind

get crashflip

set – Change Settings

set yaw_expo = 0

This modifies a parameter.

save – Apply Modifications

save

Modifications are NOT saved till you run the save command. This can reboot the flight controller.

exit – Go away With out Saving

exit

Use this for those who don’t wish to save modifications.

Tip: For backup and restore, there’s no want to make use of CLI these days, the method is now simplified by utilizing the Preset tab as defined right here: https://oscarliang.com/backup-restore-betaflight-config/

Ideas and Methods

Press TAB to Auto-Full

Begin typing a command and press TAB to auto-complete or see solutions.

Begin typing a command and press TAB to auto full. If there are a number of choices, the CLI will counsel all prospects. That is handy, particularly for lengthy instructions.

Don’t Neglect to SAVE!

At all times kind save earlier than exiting CLI if you wish to preserve the modifications.

Bootloader Mode (DFU)

As an alternative of urgent the boot button on the FC, you’ll be able to put the FC into bootloader mode (DFU mode) by coming into this command:

bl

To exit DFU mode, unplug (energy off FC) and reconnect the USB cable.

System Monitoring

The process command exhibits the CPU load of all processes operating on the flight controller. That is nice for troubleshooting in case your FC is experiencing CPU load points.

Instructions May Have Modified – Get Assist!

Some command title may change from model to model. When doubtful, you’ll be able to at all times verify the accessible instructions utilizing assist.
