Command Line Interface (CLI)
AlphaFly has a command line interface (CLI) that can be used to change settings and configure the FC.
Accessing the CLI.
The CLI can be accessed via the AlphaFly App or via a terminal emulator connected to the CLI serial port.
AlphaFly has a command line interface (CLI) that can be used to change settings and configure the FC
Accessing The CLI with a Terminal Emulator
The CLI can be accessed via the CLI Tab in the AlphaFly App or via a terminal emulator connected to the CLI serial port.
- Connect your terminal emulator to the CLI serial port (which, by default, is the same as the MSP serial port)
- Use the baudrate specified by msp_baudrate (115200 by default).
- Send a
#character.
CLI Usage
To save your settings type in 'save', saving will reboot the flight controller.
To exit the CLI without saving power off the flight controller or type in 'exit'.
To see a list of other commands type in 'help' and press return.
To dump your configuration (including the current profile), use the 'dump' command.
See the other documentation sections for details of the cli commands and settings that are available.
Backup via CLI
info
Backup and Restore is now supported in the Presets Tab. This method is quicker and does not reqire CLI usage
Disconnect main power, connect to cli via USB/FTDI.
Diff Backup Using CLI
This method shows all user-modified settings but avoids saving values left as default or values that are part of the board targets
Note that diff only shows the current Rate and PID profiles, whereas diff all will show all profiles that have been
changed
diff all
This data should be sufficient to replicate the quad configuration on a new or erased flight controller board. Use the save to file function to create a backup
Dump Using CLI
Note that the dump command will output every setting and their current values. Many of these will be firmware
defaults and are not needed to backup quad configuration changes

copy screen output to a file and save it.
Restore via CLI
info
Backup and Restore is now supported in the Presets Tab. This method is quicker and does not reqire CLI usage
Use the cli defaults command first.
When restoring from a backup it is a good idea to do a dump of the latest defaults so you know what has changed - if you do this each time a firmware release is created you will be able to see the cli changes between firmware versions. For instance, in December 2014 the default GPS navigation PIDs changed. If you blindly restore your backup you would not benefit from these new defaults.
Use the CLI and send all the output from the saved backup commands.
Do not send the file too fast, if you do the FC might not be able to up when using USART adapters (including built in ones) since there is no hardware serial flow control.
You may find you have to copy/paste a few lines at a time.
Repeat the backup process again!
Compare the two backups to make sure you are happy with your restored settings.
Re-apply any new defaults as desired.

Variable
| Description/Units | Min | Max | Default | Type | Datatype |
|---|---|---|---|---|---|---|
mid_rc
| This is an important number to set in order to avoid trimming receiver/transmitter. Most standard receivers will have this at 1500, however Futaba transmitters will need this set to 1520. A way to find out if this needs to be changed, is to clear all trim/subtrim on transmitter, and connect to the AlphaFly App. Note the value most channels idle at - this should be the number to choose. Once midrc is set, use subtrim on transmitter to make sure all channels (except throttle of course) are centered at midrc value. | 1200 | 1700 | 1500 | Master | UINT16 |
min_check
| These are min/max values (in us) which, when a channel is smaller (min) or larger (max) than the value will activate various RC commands, such as arming, or stick configuration. Normally, every RC channel should be set so that min = 1000us, max = 2000us. On most transmitters this usually means 125% endpoints. Default check values are 100us above/below this value. | 0 | 2000 | 1100 | Master | UINT16 |
max_check
| These are min/max values (in us) which, when a channel is smaller (min) or larger (max) than the value will activate various RC commands, such as arming, or stick configuration. Normally, every RC channel should be set so that min = 1000us, max = 2000us. On most transmitters this usually means 125% endpoints. Default check values are 100us above/below this value. | 0 | 2000 | 1900 | Master | UINT16 |
rssi_channel
| RX channel containing the RSSI signal | 0 | 18 | 0 | Master | INT8 |
rssi_scale
| When using ADC RSSI, the raw ADC value will be divided by rssi_scale in order to get the RSSI percentage. RSSI scale is therefore the ADC raw value for 100% RSSI. | 1 | 255 | 30 | Master | UINT8 |
rssi_invert

rx_max_usec
| Defines the longest pulse width value used when ensuring the channel value is valid. If the receiver gives a pulse value higher than this value then the channel will be marked as bad and will default to the value of mid_rc. | 750 | 2250 | 2115 | Master | UINT16 |
serialrx_provider

max_throttle
| These are min/max values (in us) that are sent to ESC when armed. Defaults of 1150/1850 are OK for everyone, for use with AfroESC, they could be set to 1064/1864. If you have brushed motors, the value should be set to 2000. | 0 | 2000 | 1850 | Master | UINT16 |
