I'm trying to make a RC car (with a surveillance camera if possible, using the web-cam code that comes with the ESP library) using a ESP-32 CAM as a wifi module to control the car using my computer. Problem is that I keep getting the "invalid head of packet" error whenever I try uploading anything. I've tried holding the boot button as I upload and I cannot use the capacitor simply because I don't have it and don't want to buy it and spend time getting it. I also have the GPIO0 pin connected to GND during the uploading process. Any other ways to get it working? My car consists of 2 DC motors powering only the back two wheels and a servo that steers the front wheels, and I want to use the ESP32-CAM to connect to wifi to connect to a webserver from my pc to control the car.
