The esp-idf framework includes the lwIP library to implement the TCP/IP stack protocol. This library is an asynchronous TCP library for the ESP32 and it is the base for the ESPAsyncWebServer library implementation [2]. To declare an async class method, just prepend it with async: class Waiter { async wait() { return await Promise. Async version of the Rust standard library. The MQTT library implements a subset of the MQTT 3. getFlashChipSize() returns the flash chip size, in bytes, as seen by the SDK (may be less than actual size). This is a fully asynchronous TCP library, aimed at enabling trouble-free, multi-connection network environment for Espressif’s ESP8266 MCUs. For ESP8266 it requires ESPAsyncTCP To use this library you might need to have the latest git versions of ESP8266 Arduino Core. --> ESP32 D1 R32 Affected component:
