Does ESP32 need Wi-Fi?
The ESP32 can act as a Wi-Fi station, as an access point, or both. This way, you don’t need to be connected to a router to control your ESP32. Because the ESP32 doesn’t connect further to a wired network (like your router), it is called soft-AP (soft Access Point).
How does ESP32 Wi-Fi work?
When you set your ESP32 board as an access point, you can be connected using any device with Wi-Fi capabilities without connecting to your router. When you set the ESP32 as an access point, you create its own Wi-Fi network, and nearby Wi-Fi devices (stations) can connect to it, like your smartphone or computer.
How do you upload a code to ESP32-Cam?
2) Go to Tools > Port and select the COM port the ESP32-CAM is connected to. 4) Then, click the Upload button in your Arduino IDE. 5) When you start to see some dots on the debugging window, press the ESP32-CAM on-board RST button. After a few seconds, the code should be successfully uploaded to your board.
How do I communicate with ESP32 over Wi-Fi?
TCP Servers let you send and receive data from wireless devices like the ESP32/ESP8266 in much the same way as you’d use a Serial connection on an Arduino Uno. You need to create a WiFiServer object and set the port it will listen for connections on.
Do you need router to access ESP32 Cam?
In this scenario, the router acts as an access point and the ESP32-CAM board is set as a station. So, you need to be connected to your router (local network) to control and access the ESP32-CAM web server. In some cases, this might not be the best configuration (when you don’t have a router nearby).
What does it mean to set ESP32 Cam as soft access point?
Basically, when you set the ESP32-CAM as an access point you create its own Wi-Fi network and nearby Wi-Fi devices (stations) can connect to it (like your smartphone or your computer). Because the ESP32-CAM doesn’t connect further to a wired network (like your router), it is called soft-AP (soft Access Point).
Do you need a FTDI adapter for the ESP32 Cam?
Using the ESP32-CAM is similar to using the ESP32 modules we looked at previously, with one major difference. The ESP32-CAM board has no USB port, so you can’t just connect it up to your computer and start loading programs. Instead you will need to add an external FTDI adapter.
Why is my ESP32 not connecting to my computer?
It means that you haven’t selected the COM port in the Tools menu. In your Arduino IDE, go to Tools > Port and select the COM port the ESP32 is connected to. It might also mean that the ESP32-CAM is not establishing a serial connection with your computer or it is not properly connected to the USB connector.
