How to Update iFlight Commando Receiver Firmware

CoreWingAbout 5 minRemote controlELRS固件更新iFlightCommando高频头WiFi

Important

Ensure you have selected the correct device category for your hardware (2.4GHz or 900MHz). You cannot use firmware from a 900MHz module to flash a 2.4GHz module, nor can you use firmware from a 2.4GHz module to flash a 900MHz module, because they use different hardware.

I. Via WiFi

On your computer, start ExpressLRS Configurator, and select WiFi in the Flashing Method option

Method 1: Manual Upload via Local WiFi

Important

This method is only available if you have previously flashed or configured your TX module to use your home WiFi SSID and password, and the module can successfully connect to that WiFi network.

  1. On your computer, start ExpressLRS Configurator, ensure the Official Releases tab is active, and select the Released version to flash to the TX module.

  2. Select the Device Category and Device target that match your hardware.
  • Device Category: iFlight 2.4 GHz, Flight 900 MHz
  • Device: iFlight 2.4GHz TX or iFlight 2.4GHz TX V2, iFlight 900MHz TX or iFlight 900MHz TX V2

  2. Set the firmware options for the device.
  • Regulatory Domain (required, select the domain appropriate for your location or country/region where you will be flying)
  • Binding Phrase (optional but highly recommended. Note this phrase as it should be the same on your other devices, otherwise they won't bind or sync)
  • Local WiFi Network Credentials (optional. Will be used when the device next enters WiFi mode).

  1. Click the Build button.

  2. After the build process is complete, a Temp folder window should pop up.
  • Do not close this Temp folder as this is where you will get the firmware file for the next steps.
  • If you plan to use a phone or tablet to upload the firmware file later, copy the firmware file to your device.

Important

With the release of ExpressLRS 3.3.0 and ExpressLRS Configurator 1.6.0, only one file firmware.bin will be displayed, use this file for the subsequent steps.

7. Press the SYS key on your transmitter, the radio will display the tools menu where you can find the Lua script.

  • Older radios or radios with only one menu button must long-press the Menu key to access the System Menu.
  • Refer to your Radio user manual for instructions on how to access the system menu.
  1. Scroll down and select ExpressLRS. If you can't find the script, download the ExpressLRS Lua script and save it to your Radio's SD Card Scripts/Tools/ folder.

    This method is only available if you have previously flashed your TX module to use your home WiFi SSID and password, and the module can successfully connect to that WiFi network.
    Additionally, MDNS must be working properly for your browser to resolve the address http://elrs_tx.local and load the ExpressLRS Web UI from that address.
  9. Press the SYS key on your transmitter, the radio will display the tools menu where you can find the Lua script.
  • Older radios or radios with only one menu button must long-press the Menu key to access the System Menu.
  • Refer to your Radio user manual for instructions on how to access the system menu.
  1. Scroll down and select ExpressLRS. If you can't find the script, download the ExpressLRS Lua script and save it to your Radio's SD Card Scripts/Tools/ folder.

II. External TX Module via UART

Start ExpressLRS Configurator on your computer and select UART in the Flashing Method option.

  1. Unscrew the two screws securing the TX module to the back of the transmitter. Carefully lift the TX module and connect its USB-C port to your computer. Do not apply excessive force as there is a connecting cable between the TX module and the transmitter's main board.

  2. Confirm that your TX module is properly detected as a USB to UART device. Windows users can check this in the Ports (COM & LPT) section of Device Manager.
    If the TX module is not properly detected, you will need drivers. Common USB to UART chips used in ExpressLRS modules include: CP210x, CH340, and CH9102 (link to driver download page).
