Which WiFi protocol does ESP32 support?
ESP32 implements TCP/IP, full 802.11 b/g/n/e/i WLAN MAC protocol, and Wi-Fi Direct specification. This means ESP 32 can speak to most of the WiFi Routers out there when used in station(client) mode. Also it is able to create an Access point with full 802.11 b/g/n/e/i. ESP32 also supports the Wi-Fi Direct .
What can ESP32 do?
ESP32 can perform as a complete standalone system or as a slave device to a host MCU, reducing communication stack overhead on the main application processor. ESP32 can interface with other systems to provide Wi-Fi and Bluetooth functionality through its SPI / SDIO or I2C / UART interfaces.
Why ESP32 does not connect to Wi-Fi?
messages, press the RESET button of your board (or unplug and re-plug its power to reset) and and try again.
What are the Wi-Fi key features of ESP32?

How does ESP32 Wi-Fi work?
The ESP32 server creates its own wireless network (ESP32 Soft-Access Point). So, other Wi-Fi devices can connect to that network (SSID: ESP32-Access-Point, Password: 123456789). The ESP32 client is set as a station. So, it can connect to the ESP32 server wireless network.
How to connect an ESP32 to a WiFi network?
Select the number for your network SSID: Enter the password for this network: When the ESP32 connects to the Wi-Fi network, the ESP32 IP address is shown and the Bluetooth is disconnected: If the ESP32 already has the correct connection credentials then just the IP address of the ESP32 will be displayed:
What does ESP32 stand for in packet radio?
Wireless packet radio interface for HF/VHF/UHF transceivers, using ESP32 as KISS TNC or audio relay for use with soft modems This ESP32-based device provides Wifi, Bluetooth, and USB serial connections between a host computer and an HF, VHF, or UHF transceiver to facilitate digital data transmission.
What does ESP32 do for a HF transceiver?
This ESP32-based device provides Wifi, Bluetooth, and USB serial connections between a host computer and an HF, VHF, or UHF transceiver to facilitate digital data transmission. The device offers two operating modes and an html user interface for mode selection, configuration, and signal analysis.
Can you use Bluetooth Classic on the ESP32?
In summary, the ESP32 supports BLE and Bluetooth Classic. Using Bluetooth Classic is as simple as using serial communication and its functions. If you want to learn how to use BLE with the ESP32, you can read our guide: Getting Started with ESP32 Bluetooth Low Energy (BLE) on Arduino IDE.
