For some reason the ESP32-CAM is no longer talking to my rover’s UNO board. I’ve pulled it and tried talking to it directly over serial but I’m not getting any answer. Is the firmware available so I can reflash mine to see if that might help?
When I watch serial for the rover itself I’m seeing this as the output.
---- Opened the serial port /dev/ttyUSB0 ----
GalaxyRVR version 1.1.0

Never mind, I found it at git@github.com:sunfounder/ai-camera-firmware.git
We recommend trying to update the firmware of your ESP32-CAM to see if it resolves the issue.
If you encounter any further problems, please feel free to contact us at service@sunfounder.com.
I’m having the same issue, would you mind explaining the process for how you reflashed the firmware of the esp32-cam with the files from the github?
We recommend that you follow our follow the steps to update the firmware:
https://docs.sunfounder.com/projects/galaxy-rvr/en/latest/faq.html#how-to-update-firmware-for-esp32-cam
If you are unable to connect to the GalaxyRVR’s WiFi to update the firmware, you will need to prepare an ESP32 CAM burner to burn the firmware to the ESP32 CAM module.
https://github.com/sunfounder/ai-camera-firmware/releases/download/1.4.1/burn.esp32-cam.bat.zip
After downloading the zip file, unzip the file.
ESP32 CAM connect to the ESP32 CAM burner, use the data cable to connect to the USB port of the computer, open the folder and double-click the install_ESP32.bat file, then you can carry out the sample firmware.
Dumb question, but can you verify that you have a COM4 that’s connected to an ESP32? You might need to hunt down a tool called usbview.exe (it’s been a very long time since I had to work in Windows so I’m guessing). You should also open Device Manager and make sure that the USB device is connected. Can you talk to any arduino or ESP32 or any other kind of device, or is this your first try at flashing a device?
michaeljon is correct.
If you normally use a cable to connect the ESP32 to your computer’s USB port and make sure the serial port is COM4.
Another possibility is that the serial driver is not compatible and you need to update the serial driver.
Go ahead and update the firmware again and see how it works. This is really quite a complicated thing, if you are not familiar with this area.
If this is not possible, we can send you a new ESP32 module.
I got it working! I was able to flash it using a ESP32-CAM-MB, however I had to downgrade to V 1.4.0 for it to work. When I used V 1.4.1 it would connect via Wifi but when I was in the app the moment I would press the “play” button to display the cameras view it would immediately disconnect. Not sure what could be causing that problem.
We have not reproduced your issue at this time. Can you tell us the version of the app you’re using and the platform.
