Update Firmwares

Your device may not have the latest firmware due to ongoing product improvements. To ensure optimal and stable performance, please follow the steps below to check and update the firmware on your ESP32 CAM and R3 board.

1. Check Whether an Update Is Needed

  1. Before using the GalaxyRVR for the first time, fully charge the battery with the supplied Type-C USB cable. After charging, turn the power on.

  2. To start the ESP32 CAM, switch the mode to Run and press the Reset button on the R3 board. The bottom light strip will begin flashing to indicate a successful startup.

    Note

    • If the bottom light strip shows a green flashing light, your ESP32 firmware is already up to date.

    • You may proceed to Quick Start.

  3. If the bottom light strip flashes other color, you will need to:

2. Updating the ESP32 CAM Firmware

The ESP32 CAM broadcasts the Wi-Fi hotspot and captures video for the GalaxyRVR. If the firmware is outdated, these functions may not work properly. Follow the steps below to update the firmware.

  1. Turn on the GalaxyRVR’s power switch. To start the ESP32 CAM, switch the mode to Run and press the Reset button on the R3 board.

  2. Download the firmware file.

  3. Extract the downloaded ZIP file. Locate the firmware file named ai-camera-firware.ino.x.x.x.bin and transfer it to your mobile device. You can use any file manager app, such as ES File Explorer or a file transfer utility.

  4. Connect your mobile device to the GalaxyRVR’s WiFi network.

    • The network name (SSID) is GalaxyRVR and the password is 12345678.

    • If you see a warning stating “No Internet access,” please choose the option to “Stay connected.”

  5. Open a web browser on your mobile device and go to the address http://192.168.4.1. This will take you to the ESP32-CAM firmware update portal.

  6. On the OTA page, check the current firmware version displayed on the webpage.

    • If your version number is higher than 1.5.1, an update is not required. You can skip the remaining steps and proceed directly to Quick Start.

    • If the version is 1.5.1 or lower, please continue with the update.

  10. Wait for the firmware upgrade to complete.

    • The upload process typically takes 1-2 minutes. Once finished, a success message will appear in a pop-up window.

    • You can then select CONFIRM to restart the GalaxyRVR or CLOSE to dismiss the window.

3. Updating the R3 Board Firmware

The R3 board includes built-in firmware that enables communication with the RoboPilot APP and Mammoth Coding.

You need to re-upload this firmware if:

  • Your device uses an older firmware version, or

  • You have flashed your own Arduino code and want to restore compatibility.

Follow the steps below to reinstall the communication firmware.

  1. Connect the Arduino and computer with a USB cable, and then turn the upload switch of the car to the upload end.

    _images/camera_upload.png

    Note

    It is the USB Type B port for connecting to Arduino, not the USB Type C port for charging.

  2. Check whether the firmware files have been downloaded.

  3. Run the update script

    • Open the galaxy-rvr-1.2.0 folder (downloaded and installed in the previous step).

    • Double-click the update-arduino-firmware.bat script.

    • A command prompt window will appear automatically.

  4. Select the serial port and upload

    • In the command prompt, a list of available serial ports will be displayed.

    • Enter the sequence number shown on the left to select the Arduino Uno’s serial port.

    • Press Enter to begin the automatic upload.

    • Example: If the list shows 1 USB-SERIALXXX (COMxx), enter 1 and press Enter.

Note

This code enables the GalaxyRVR to respond to APP commands. You won’t need to upload any additional code when using either the RoboPilot remote control APP or the Mammoth Coding software.
