Hello,
I don't know anything about coding. But I was trying to make a cable release board using the instructions found in this link on Youtube (click here for reference). It's an ESP32 board that's powering a servo motor via a battery and is being controlled by bluetooth. I used Arduino to do the coding. I got everything down execept bluetooth part. This ESP32 board is to be BATTERY OPERATED using the appropiate pins. When I hook it up to the pins, the ESP32 board turns on/works fine, but my phone can't find the board via bluetooth. HOWEVER, when the ESP32 board is powered through the USB port, it can be found using bluetooth. I'm wrecking my brain trying to find out how to fix this. I can't use the USB port to power the device because then I can't power the motor. Help please? Again, I'm not a coder, so PLEASE speak to me like I'm a 5 year old. I promise I won't be offended
