Flashing via WiFi¶

• Target:

  • RadioMaster_Ranger_2400_TX_via_WIFI
  • RadioMaster_Ranger_Micro_2400_TX_via_WIFI
  • RadioMaster_Ranger_Nano_2400_TX_via_WIFI

• Device Category: Radiomaster 2.4 GHz

• Device:

  • RadioMaster Ranger 2400 TX
  • RadioMaster Ranger Micro 2400 TX
  • RadioMaster Ranger Nano 2400 TX

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 RadioMaster_Ranger_2400_TX-<version>.bin, RadioMaster_Ranger_Micro_2400_TX-<version>.bin or RadioMaster_Ranger_Nano_2400_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. Insert/attach your module into your module bay and make sure it's not loose and there's a proper connection with the radio (see the [Radio Preparation] page). 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 or that your module is not well-connected to the module bay pins.

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 the Web UI. Navigate to the Update Tab and you should see a File Upload form. You can now drag-and-drop the RadioMaster_Ranger_2400_TX-<version>.bin, RadioMaster_Ranger_Micro_2400_TX-<version>.bin or RadioMaster_Ranger_Nano_2400_TX-<version>.bin file that the ExpressLRS Configurator created into the File Upload field. 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 screen 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 RadioMaster_Ranger_2400_TX-<version>.bin, RadioMaster_Ranger_Micro_2400_TX-<version>.bin or RadioMaster_Ranger_Nano_2400_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. Navigate to the Update Tab and you should see a File Upload form. You can now drag-and-drop the RadioMaster_Ranger_2400_TX-<version>.bin, RadioMaster_Ranger_Micro_2400_TX-<version>.bin or RadioMaster_Ranger_Nano_2400_TX-<version>.bin file that the ExpressLRS Configurator created 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.

Once the file is uploaded, a pop-up confirmation will show up. Wait for the Lua script screen 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.

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.
