Global functions are special functions that apply to all models on the Radio. They are configured exactly as model Special Functions and the same functions are available. For more information about configuring Global Functions, refer to the Special Functions section as they are essentially the same.

Pressing the [PAGE>] button will take you to the Trainer screen.

The Trainer screen in Radio Settings is used to configure how the radio in Master mode will handle the signals from the radio in Slave mode. It contains the below configuration options.

For each of the four main control inputs (Ail, Ele, Thr, Rud), the following options can be configured (for each row, from left to right).

Mode - How the radio in Master mode will handle the signals from the radio in Slave mode.

• OFF - Stick values from the radio in Master mode will be used - no input from the radio in Slave mode.

• += Adds the stick values from both the radios in Master and Slave modes.

• := Replaces the stick values from the radio in Master mode with the stick values from the radio in Slave mode. (Default)

• Weight - Percentage of stick travel to use of the radio in Slave mode. Use negative values to change the stick direction.

• Source channel - The channel from the radio in Slave mode that is mapped the control input.

Multiplier - This value changes the weight of all the sticks together.

Cal (calibrate)- Sets the center stick value of the radio in Slave mode.

Pressing the [PAGE>] button will take you to the Hardware screen.

The Hardware screen is where you configure hardware specific-settings for your radio. It shows all physical hardware objects (sticks, pots, switches) and allows for their modifications. It is also where you can calibrate your sticks and pots. It also contains additional configuration options.

Calibration

To calibrate your physical radio controls (sticks, pots, sliders, & 6-position switch), highlight the [Calibration] option and press the [Enter] button. The radio will prompt you through the calibration steps.

Inputs, Sticks, Pots, and Switches Buttons List

Selecting one of the Sticks, Pots, or Switches lines from the list will allow you to add a 3 character label to the control as well as change the type of control as needed.

Additional hardware configuration options

Batt. Calib (Battery Calibration) - Set this value to match the transmitter battery voltage. This ensures that the displayed battery voltage is accurate.

RTC Batt - The current voltage of the RTC battery. The RTC (real time clock) battery keeps the radio's date and time accurate even when no main radio battery is present.

Check RTC - When enabled, checks the RTC battery at startup and warns you if the battery voltage is low.

Audio Mute - When enabled, puts the transmitter in mute mode until a sound needs to be played. This prevents interference noise from high-powered TX modules from coming out of the transmitter speakers.

Internal RF Type - Select the module type for the internal module bay. Options are: Multi, XJT, ISRM, CRSF. When CRSF is selected, you can also select the baud rate. You can read more about baud rates here.

Sample Mode (External RF)- Options are Normal and OneBit. The default setting of Normal should be used by most users. Only users of X9D+ and X7 radios may want to use OneBit mode.

Bluetooth

Mode - mode that the bluetooth module will be used in. The options are:

• --- - Off

• Telemetry - used for sending telemtry data over bluetooth.

• Trainer - used for bluetooth trainer mode

One a mode is selected, you will see the following information:

• PIN Code - PIN code for bluetooth device in the radio (visible in Telemetry mode only)

• Local addr - Identifying address of the bluetooth device in the radio.

• Dist addr - Identifying address of bluetooth device that radio is connected to.

Name - the name the bluetooth device will be seen as.

Serial Port - Displays a list of available auxiliary serial ports that can be configured and used. The listed ports are based on the ports that are available in the particular radio hardware. The ports listed below are for example only and may not be present in your radio.

• AUX1 - First available auxiliary serial port can be configured with the below options:

  • OFF - Turned off.

  • Telem Mirror - The same telemetry data that goes to the external module bay is sent to the serial port.

  • Telemetry In - Receive telemetry data over the serial port.

  • SBUS Trainer - Connect the Instructor and Student radios over the serial port.

  • LUA - Send/receive data to/from Lua script.

  • GPS - Receive GPS telemetry data over the serial port.

  • CLI - Send commands to the radio via the command line.

• USB-VCP - Virtual COM Port. This is one of the options presented when connecting your radio to the PC with most radios. Is often set to 'CLI' for radios with internal ExpressLRS RF modules in order to do firmware updates.

ADC Filter - Enables or disables the ADC Filter. This filter can also be enabled/disabled per model in the model settings.

RAS - (Formerly SWR) Reflected antenna signal. Lower numbers are better, with a 1:1 ratio being theoretically the best. Not supported by all RF Protocols.

Debug

The debug section allows for testing and debugging of the analog controls and keys.

Debug Analogs - These screens will show you the data for your analog controls (Sticks, Sliders, Pots, 6-position switch). There are two views - Calibrated Analogs, Raw Analogs (5 Hz).

Pressing the [PAGE>] button will take you to the Global Functions screen.

Tools

Pressing the [SYS] button from the Main view will open the Tools screen.

The Tools page in Radio Settings is where you can select Lua script-based tools for execution. Lua scripts that are located on the SD card in the Tools folder will be listed here. Selecting a tool will execute it. By default, EdgeTX includes several tools. Other tools can be downloaded and added to the SD card as well. The following tools are included in the default EdgeTX SD card.

Wizard Loader

The Wizard Loader tool assists you in setting up a new model by running a setup wizard for a particular model type. Once the model type is selected, the wizard will take you through a series of prompts and then configure your selected model based on the information provided.

NOTE: The wizard does not create a new model, it only configures the currently selected model. You must manually create a new model first and then run the wizard. If you run this wizard on an already configured model, it will overwrite your model settings!

Pressing the [PAGE>] button will take you to the SD Card screen.

The SD Card screen shows you the contents of your SD card, allows you to navigate the folders and interact with the files in the folders. All folders contain a README.txt file that describes what type of files belong in this folder. After selecting a file in one of the folders, you will be presented with some of the options below, depending on the file type that was selected:

• Assign bitmap - Assigns the selected image file as the model image of the currently selected model.

• Copy - Copies the selected file.

• Delete - Deletes the selected file.

• Execute - Executes a Lua script. Used for files ending in .lua

• Flash [target]- Flashes the selected firmware file to the select target module. Examples: Flash Bootloader, Flast Internal Multi.

• Paste - Pastes the copied file.

• Play - Plays the selected sound file.

• Rename - Renames the file.

• View text - Views the selected .txt or .csv file.

The folders listed on the SD card screen are the same as what you will see when connecting your radio to your computer. Below are the folder names and explanations for all the folders that come with the default EdgeTX SD Card.

BACKUP

The backup folder contains model files for models that were backed up from the EEPROM. This folder will only be present on radios that store the model files in EEPROM.

FIRMWARE

Place the firmware files that you want to flash in this folder. This folder is empty by default (except for the readme.txt file). When selecting a .bin file you will be given the option to flash the firmware to a particular module. Also, only firmware files in this location will be visible from the bootloader menu.

IMAGES

NOTE: This folder is only used for radios with 212x64 displays.

Place your custom model image files in this folder. This folder is empty by default (except for the readme.txt file). Selecting an image file will give you the option to Assign Bitmap, which assigns the selected image file as the model image of the currently selected model.

The ideal image size for model images is 64x32 pixels. The picture format should be .bmp The image file name should not exceed 9 characters and the image formatting should be 4 bit indexed colored mode.

LOGS

MODELS

This is where the model files, label information, and preflight checklists are stored. Each model will have a model[#].yml file that contains all configured options.

Models that are deleted via the radio will be moved to the DELETED folder that is included in this folder. The remaining model files are what will be visible on the Model Select screen.

If you have configured the Display checklist option in model settings, the model notes file goes in this folder. The model notes file must be a .txt file and must have the EXACT same name as the model it is for, for example: Mobula6.txt. The text in the file is up to the user.

RADIO

This folder contains the radio.yml file. This file contains all the radio configuration data. If this file is corrupted or missing, the radio will go into Emergency Mode and will create a new radio.yml file with the default settings.
