Flashing NamimnoRC Flash

Setup-Banner

2nd Gen, OLED-equipped

These newer devices are now using an ESP-based MCU compared to the first version. With this in mind, the Flashing method will differ slightly, and should now be the same as with other ESP-based Tx Modules.

Flashing via WiFi

Target: NamimnoRC_FLASH_2400_OLED_TX_via_WIFI

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 NamimnoRC_FLASH_2400_OLED_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 ExpressRLS 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 proper connection with the radio (see the Radio Preparation page). Execute the ExpressLRS lua script by pressing "System Menu" in your radio and then under Tools, select ExpressLRS.

Lua Script Lua Script T16

If the script is stuck at Loading..., then there's a chance your module is still in v1.x firmware, your External RF module is not set to CRSF or that your module is not well-connected to the module bay pins.

Lua3

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 Module, 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 NamimnoRC_FLASH_2400_OLED_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 screen to close the "WiFi Running" screen and your module should be updated now.

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

Update for version 2.0

Once you have updated to firmware version 2.0 or newer, the Web Update page on the Hotspot will get a few updates of its own. It will get the Update progress bar, and a Popup will be shown for Success or Error messages. Additionally, 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 two methods below.

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 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:

Firmware Update

Drag-and-drop the NamimnoRC_FLASH_2400_OLED_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 (~1min).

Verify the version and hash in the main screen of 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 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.

Flashing via USB/UART

Target: NamimnoRC_FLASH_2400_OLED_TX_via_UART

Attach your USB cable into the module and your computer. CH340 Drivers will have to be downloaded (Right-click, Save-as) and installed (Unzip the contents of the file; Run the executable installer) for this to work properly (Windows). Make sure your computer recognizes the module as a USB-SERIAL CH340 device, otherwise, this method will not work.

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.

Verification can be done using the ExpressLRS lua script. It should show the Version Number and Hash at the bottom, as well as the options you can set. If it's showing "Loading" at the top, check if External Module is set to CRSF for the selected model in your radio, and that internal RF module is set to off. See General Troubleshooting section for other ways to determine your module is flashed and ready for flying.
