You asked: How do I use WiFi and Bluetooth on ESP32?

Can I use Bluetooth and WiFi at the same time in ESP32?

Bluetooth and WiFi work perfectly well together. There is no reason why they can’t share the antenna. They also share the 2.4GHz consumer band, but seem to co-exist quite happily in one or two of the applications I have written.

How do I enable WiFi on ESP32?

The ESP32 is a low cost micro made by Espressif, which supports Arduino libraries and can connect to WiFi networks. Connecting to a WiFi network is pretty easy. Just call: WiFi. begin(“SSID”, “Password”); with your network credentials: the network’s SSID and password.

What is the working frequency of WiFi and Bluetooth in the ESP32 Development Board?

Download certificates for Espressif products from www.espressif.com/en/certificates. ESP32 is a single 2.4 GHz Wi-Fi-and-Bluetooth combo chip designed with the TSMC ultra-low-power 40 nm technology.

How do I send data to ESP32 over WiFi?

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.

How do I transfer data from ESP32 to laptop?

1 Answer

  1. Create a local server on your PC, laptop whatever using an application like XAMPP (I have Windows 10 so WAMP would also work), download, install, open and start Apache.
  2. Make sure that the Firewall lets your requests pass through (for me it was open by default, but I had seen elsewhere Firewall being an issue)
