Flashing via WiFi¶

• Targets:

  • iFlight_2400_TX_via_WIFI
  • iFlight_900_TX_via_WIFI

• Device Categories:

  • iFlight 2.4 GHz
  • iFlight 900 MHz

• Devices:

  • iFlight 2400TX
  • iFlight 900TX

Method 1¶

With the correct target selected and Firmware Options set, Build your firmware using the ExpressLRS Configurator.

Once it's done, it should open the Target folder for you where the iFlight_2400_TX-<version>.bin or iFlight_900_TX-<version>.bin file is. Do not close this window so you can easily locate the correct file to upload to the module.

The next steps will require the ExpressLRS Lua script (right-click, save as). Download the ExpressLRS Lua script and save it to your Radio's /Scripts/Tools folder. Execute the ExpressLRS Lua script by pressing "System Menu" on your radio and then under Tools, select ExpressLRS.

If the script is stuck at Loading..., then there's a chance your Radio External RF module is not set to CRSF.

Select WiFi Connectivity from the Lua script and then select Enable WiFi. Press OK once more to activate the WiFi on the Tx Module. Connect to the Access Point the module will create called ExpressLRS TX, with the password being expresslrs.

Using your browser, navigate to the correct page (typically http://10.0.0.1/) and it should show an upload form (you will have to scroll down a bit). You can drag-and-drop the iFlight_2400_TX-<version>.bin or iFlight_900_TX-<version>.bin file that the ExpressLRS Configurator created. You can also click the Choose File button and navigate to the folder where the firmware was created. Ensure that you have selected the correct firmware file and click Update.

Once the file is uploaded, a pop-up confirmation will show up. Wait for the Lua script to close the "WiFi Running" screen and your module should be updated now.

Verify the version and hash in the main screen of the ExpressLRS Lua script.

Join Local Network

You can configure Home Network SSID and Password if you chose not to use ExpressLRS Configurator to set them. Once these are set, you can use the next two methods below.

Method 2¶

With the correct target selected and Firmware Options set, Build your firmware using the ExpressLRS Configurator.

Once it's done, it should open the Target folder for you where the iFlight_2400_TX-<version>.bin or iFlight_900_TX-<version>.bin file is. Do not close this window so you can easily locate the correct file to upload to the module.

Using the ExpressLRS Lua script (right-click, save as), select Wifi Connectivity then choose Enable WiFi and if you have flashed your Tx Module with your Home WiFi Network details or have set it in the Join Network section of the Update Page, it will connect to the local network automatically.

Using your browser, navigate to http://elrs_tx.local and the WiFi Update page should show up. Scroll down towards the Firmware Update section, as shown below:

Drag-and-drop the iFlight_2400_TX-<version>.bin or iFlight_900_TX-<version>.bin file created by the ExpressLRS Configurator into the Choose File field, or manually navigate to the Folder by clicking the Choose File button. Once the correct file is selected, click the Update. Wait for the process to complete, and the module will reboot (the "Wifi Running" window on the Lua Script will disappear once it has rebooted).

Verify the version and hash in the main screen of the ExpressLRS Lua script.

Method 3¶

Using the ExpressLRS Lua script (right-click, save as), select Wifi Connectivity then choose Enable WiFi and if you have flashed your Tx Module with your Home WiFi Network details or have set it in the Join Network section of the Update Page, it will connect to the network automatically.

Using the ExpressLRS Configurator, select the correct Target and set your Firmware Options. Click Build and Flash and wait for the compile process to complete. You should see a section as pictured below and the Success message marking the update process complete.

Verify the version and hash in the main screen of the ExpressLRS Lua script.

Flashing via USB/UART¶

• Targets:

  • iFlight_2400_TX_via_UART
  • iFlight_900_TX_via_UART

• Device Categories:

  • iFlight 2.4 GHz
  • iFlight 900 MHz

• Devices:

  • iFlight 2400TX
  • iFlight 900TX

Unscrew the two screws holding the Transmitter Module to the back of the radio handset. Carefully lift the Transmitter Module to get access to the USB-c port. Do not tug too much as there are wires connecting the Transmitter Module to the mainboard of the radio handset, along with the antenna cable of the module itself.

Attach a USB-C Data Cable to your module and Computer. Windows users might have to install CP210x Windows Drivers to ensure the device is properly detected and initialized. Check Device Manager to verify the TX Module appears as a CP210x USB to UART Bridge, under the Ports grouping.

Using the ExpressLRS Configurator with the correct Target selected and Firmware Options set, hit Build & Flash. Wait for the process to finish, and you should be greeted with the "Success" message.

Verify the version and hash in the main screen of the ExpressLRS Lua script.
