I would like to update ESP32-cam firmware on my Zeus car, I followed steps, download the 1.4.1 version, uploaded it with browser 192.168.4.1, reach 100% success. I just refresh the browser page to see actual version but get no connection error. I press rst button and now Zeus car won’t connect in AP mode, incorrect password. Even if I enter correctly 12345678. The only way to connect it is in STA mode. Is there a way to force update with ESP32-cam?

It could be caused by a bug in our SunFounder\_AI\_Camera library.
After you update and install SunFounder\_AI\_Camera to version 1.1.1, go back and re-upload the code and see how it works. (As shown in the picture)

It’s not into Arduino. I’ve follow this tuto to update firmware of ESP32-cam. [FAQ — SunFounder Zeus Robot Car Kit for Arduino documentation](https://docs.sunfounder.com/projects/zeus-car/en/latest/faq.html#how-to-update-firmware-for-esp32-cam) I’ve try once successful, then reconnect to ota to check if it’s the new version but still the old one : 1.4.0 . So I redo all steps and when it get at 100% success I refresh the browser page to see if current version change to 1.4.1 . But I got an error message like not connected. Since I can’t get connection by AP wifi with Zeus. I see Zeus wifi in my network list but 12345678 password doesn’t work. Is there another password for zeus\_car network?

Unfortunately, AP mode doesn’t accept the password 12345678.
Is that normal to get those error when I check files before sending to Zeus car?

If the wifi password is not correct, you can try to modify the zeus\_car/Zeus\_Car.ino file to change the password. Also note that you will need to install additional third party libraries when compiling (attached image)

It doesn’t work. Is there a way to force a firmware update of ESP32-cam without AP connection? By USB or with SD card insert into esp32 board? Or I have an ELEGOO UNO R3 kit, can I use it to update esp32 firmware?[ELEGOO UNO Project Super Starter Kit with Tutorial, 5V Relay, UNO R3, Power Supply Module, Servo Motor, 9V Battery with DC, Prototype Expansion Board, ect. for Arduino : Amazon.ca: Electronics](https://www.amazon.ca/tutoriel-dalimentation-servomoteur-dextension-prototype/dp/B01D8KOZF4/ref=mp_s_a_1_2_sspa?crid=1E8B7LQWRMX5U&dib=eyJ2IjoiMSJ9.MazmhFfn-DF8W5oyX_S-tDFAqLRDaMJSkroaZhdQMdjgp7pw-zFOOb8_l9DBkr96mGZxVAgpRmPvY2wrGhYYt54Y2Gi2nOBy_ji1D-AAWDH5fZ8O7Zch8HpqXcAtXcSIHnN5wnSWkwUVBl8Se3TkSVLj--StZmA6THVrjHINPnKze59OX_05vWy8enj9LVdP1LTH8BQvOATGj5iY0GVMUA.8Ih0sKP6rZtHvm3rPJQ1xPYbQkdg5bSTF8L0mh_3w3k&dib_tag=se&keywords=arduino+uno+r3&qid=1738543953&refinements=p_85%3A5690392011&rnid=5690384011&rps=1&sprefix=arduino+uno+r3%2Caps%2C119&sr=8-2-spons&sp_csd=d2lkZ2V0TmFtZT1zcF9waG9uZV9zZWFyY2hfYXRm&psc=1)

1. Is changing the wifi password in AP mode still connecting with an incorrect password? Or does it fail to compile?
2. Can you use STA mode to connect to ESP32-CAM, try to open the webpage to update ESP32-CAM in this mode.

Ok i found a way to connect with ESP32-cam firmware update page. after i set the STA connection, resetting Zeus car, i open sunfounder controller, scan for zeus car, then i see the IP of Zeus car. i enter it into the browser and then i can update it. It could be good to mention it into the tutorial. 192.168.4.1 is only good for AP connection.
