Supports wifi to connect to the Internet or LAN through a router, establish a TCP/UDP connection, access the user's designated server, support wired network access, and support user secondary development.
Supports serial port, wifi, Ethernet, and Bluetooth data ports in pairs. Transparent data transmission Supports firmware upgrade by connecting to the network over a wired network or wifi.
ESP32 series ICs are SOCs that integrate 2.4GHz Wi-Fi and Bluetooth dual-mode, with ultra-high stability, versatility, reliability, and ultra-low power consumption.
Here’s a rephrased version of each function with the same semantics:
1. **Socket Function**: The socket operation mode can be classified into four categories: TCP Client, TCP Server, UDP Client, and UDP Server, all of which can be configured using AT commands.
2. **Serial Communication Function**: This function allows for communication through a serial port.
3. **Bluetooth Functionality**: This enables connectivity via Bluetooth technology.
4. **Wi-Fi Functionality**: This function provides wireless network connectivity.
5. **Wired Network Access Function**: The development board can connect to the Internet or a local area network through a wired connection. The socket functionality can be adjusted via AT commands, enabling the establishment of TCP/UDP connections and accessing user-specified servers.
