Zeus car fresh out of box with no hotspot…help!

Learning kit for Raspberry Pi
1

Hi, just built Zeus car, checked wiring and downloaded app.
Followed the instructions but lights do not change to blue and stay orange when switched on. Assuming that blue means hotspot active? Cannot find it when scanning on app and remote won’t access either!
What can I do to make this work?
Help please!

  1. Have you pulled the slide switch on the expansion board to the “Run” position?
    Please see the tutorial link:

  2. Or you can re-upload the zeus-car.ino code and see how it works.

Thank you for your answer,
I have tried your tutorials already, it just won’t link up at all so I can’t access it on the app or even on the remote. Went through all the wiring and that is exactly as per instructions.
I am doing this as a project with a special needs student and really want it to work for them.

You can connect to your Zeus car in STA wifi mode, it works for me. FAQ — SunFounder Zeus Robot Car Kit for Arduino documentation

Weirdyguy said the method you can try to see.
Or you can follow our tutorial steps to re-upload the zeus-car.ino code:
https://docs.sunfounder.com/projects/zeus-car/en/latest/faq.html#how-to-upload-the-zeus-car-ino-code
Once you have uploaded the code, you will need to flip the smaller switch to the right to establish communication between the car and the ESP32 CAM.
Open the IDE’s serial monitor again, set the baud rate to 115200, check the serial port printout and provide us with a screenshot of the printout.

Seeing the same. Just built a zeus and the lights stay orange. No wifi.

Uploaded the latest Zeus_Car.ino to no avail.

13:04:45.007 → Arduino Car version 1.4.5
13:04:45.007 → Initialzing…
13:04:45.138 → SET+RESET
13:04:45.138 → …[FAIL]

The fail there is coming from the ai_camera.cpp.

Looks like the communication to the camera is hanging. The initial command to reset before grabbing the version fails FWIW:

void AiCamera::begin(const char* ssid, const char* password, const char* wifiMode, const char* wsPort) {
...
  this->get("RESET", version);

I’ve double checked all the camera cable connections and ensure the ribbon cable is properly seated etc.

I’ve also tried the STA wifi mode with no luck.

It’s working now. The small UPLOAD switch (not larger ON/OFF switch) on the shield needed to be set away from upload. Wifi and the car is now working. Hope this helps!
