Breaking change to permit coexisting with AsyncHTTPRequest library. Now you can send HTTP / HTTPS requests to multiple addresses and receive responses from them.
Please have a look at HOWTO Fix Multiple Definitions
Linker Error
Why do we need this Async AsyncHTTPSRequest_Generic library
ESP32 Core v2.0.0+ introduces new enum breaking almost all WT32_ETH01
codes written for core v1.0.6-.
It's really strange to define a breaking enum arduino_event_id_t
in WiFiGeneric.h#L36-L78, compared to the old system_event_id_t
, now placed in esp_event_legacy.h#L29-L63
It's better to preserve the old enum order and just adding new items to do no harm to pre-2.0.0 codes
- WebServer_WT32_ETH01 Releases v1.2.0-** to be used for EP32 core v1.0.6- only
- WebServer_WT32_ETH01 Releases v1.3.0+** can be used for either EP32 core v2.0.0+ or v1.0.6-. Default is using core v2.0.0+
To use with core v1.0.6-, just define in your sketch
#define USING_CORE_ESP32_CORE_V200_PLUS false
- WebServer_WT32_ETH01 Releases v1.4.0+** can be used for either ESP32 core v2.0.0+ or v1.0.6-. Autodetect core
- Asynchronous HTTPS Request library for ESP32, ESP32_S2, ESP32_C3, ESP32_S3 using built-in WiFi, WT32_ETH01 using either WiFi of built-in LAN8720 Ethernet and ESP32 boards using
LwIP ENC28J60 Ethernet
- Providing a subset of HTTPS.
- Relying on
AsyncTCP_SSL
library for ESP32 - Methods similar in format and usage to
XmlHTTPrequest
in Javascript. - Coexist with
AsyncHTTPRequest
library to permit sendingHTTP / HTTPS
requests to multiple addresses and receive responses from them
- GET, POST, PUT, PATCH, DELETE and HEAD
- Request and response headers
- Chunked response
- Single String response for short (<~5K) responses (heap permitting).
- Optional onData callback.
- Optional onReadyStatechange callback.
This library adds a simple HTTPS layer on top of the AsyncTCP_SSL library to facilitate REST communication from a Client to a Server. The paradigm is similar to the XMLHttpRequest in Javascript, employing the notion of a ready-state progression through the transaction request.
Synchronization can be accomplished using callbacks on ready-state change, a callback on data receipt, or simply polling for ready-state change. Data retrieval can be incremental as received, or bulk retrieved when the transaction completes provided there is enough heap to buffer the entire response.
The underlying buffering uses a new xbuf class. It handles both character and binary data. Class xbuf uses a chain of small (64 byte) segments that are allocated and added to the tail as data is added and deallocated from the head as data is read, achieving the same result as a dynamic circular buffer limited only by the size of heap. The xbuf implements indexOf and readUntil functions.
For short transactions, buffer space should not be an issue. In fact, it can be more economical than other methods that use larger fixed length buffers. Data is acked when retrieved by the caller, so there is some limited flow control to limit heap usage for larger transfers.
Request and response headers are handled in the typical fashion.
Chunked responses are recognized and handled transparently.
This library is based on, modified from:
- ESP32-S2 (ESP32-S2 Saola, AI-Thinker ESP-12K, etc.) using EEPROM, SPIFFS or LittleFS.
- ESP32-C3 (ARDUINO_ESP32C3_DEV) using EEPROM, SPIFFS or LittleFS.
- ESP32-S3 (ESP32S3_DEV, ESP32_S3_BOX, UM TINYS3, UM PROS3, UM FEATHERS3, etc.) using EEPROM, SPIFFS or LittleFS.
- ESP8266 using either WiFi or W5x00/ENC28J60 Ethernet
- RP2040W using arduino-pico core
- STM32 using built-in LAN8742A
- Portenta_H7 using either Ethernet or built-in WiFi
- ESP32 using either LwIP W5x00, LAN83848, etc. Ethernet

The best and easiest way is to use Arduino Library Manager
. Search for AsyncHTTPSRequest_Generic
, then select / install the latest version. You can also use this link for more detailed instructions.
- Navigate to AsyncHTTPSRequest_Generic page.
- Download the latest release
AsyncHTTPSRequest_Generic-main.zip
. - Extract the zip file to
AsyncHTTPSRequest_Generic-main
directory - Copy the whole
AsyncHTTPSRequest_Generic-main
folder to Arduino libraries' directory such as~/Arduino/libraries/
.
- Install VS Code
- Install PlatformIO
- Install AsyncHTTPSRequest_Generic library by using Library Manager. Search for AsyncHTTPSRequest_Generic in Platform.io Author's Libraries
- Use included platformio.ini file from examples to ensure that all dependent libraries will installed automatically. Please visit documentation for the other options and examples at Project Configuration File
In Platform IO, to fix the error when using LittleFS_esp32 v1.0
for ESP32-based boards with ESP32 core v1.0.4- (ESP-IDF v3.2-), uncomment the following line
from
//#define CONFIG_LITTLEFS_FOR_IDF_3_2 /* For old IDF - like in release 1.0.4 */
to
#define CONFIG_LITTLEFS_FOR_IDF_3_2 /* For old IDF - like in release 1.0.4 */
It's advisable to use the latest LittleFS_esp32 v1.0.5+
to avoid the issue.
Thanks to Roshan to report the issue in Error esp_littlefs.c 'utime_p'
The current library implementation, using xyz-Impl.h
instead of standard xyz.cpp
, possibly creates certain Multiple Definitions
Linker error in certain use cases.
You can include this .hpp
file
// Can be included as many times as necessary, without `Multiple Definitions` Linker Error
#include "AsyncHTTPSRequest_Generic.hpp" //https://github.com/khoih-prog/AsyncHTTPSRequest_Generic
in many files. But be sure to use the following .h
file in just 1 .h
, .cpp
or .ino
file, which must not be included in any other file, to avoid Multiple Definitions
Linker Error
// To be included only in main(), .ino with setup() to avoid `Multiple Definitions` Linker Error
#include "AsyncHTTPSRequest_Generic.h" //https://github.com/khoih-prog/AsyncHTTPSRequest_Generic
Check the new multiFileProject example for a HOWTO
demo.

Please have a look at ESP_WiFiManager Issue 39: Not able to read analog port when using the autoconnect example to have more detailed description and solution of the issue.
ADC1
controls ADC function for pins GPIO32-GPIO39ADC2
controls ADC function for pins GPIO0, 2, 4, 12-15, 25-27
Look in file adc_common.c
In ADC2, there're two locks used for different cases:
lock shared with app and Wi-Fi: ESP32: When Wi-Fi using the ADC2, we assume it will never stop, so app checks the lock and returns immediately if failed. ESP32S2: The controller's control over the ADC is determined by the arbiter. There is no need to control by lock.
lock shared between tasks: when several tasks sharing the ADC2, we want to guarantee all the requests will be handled. Since conversions are short (about 31us), app returns the lock very soon, we use a spinlock to stand there waiting to do conversions one by one.
adc2_spinlock should be acquired first, then adc2_wifi_lock or rtc_spinlock.
- In order to use
ADC2
for other functions, we have to acquire complicated firmware locks and very difficult to do - So, it's not advisable to use
ADC2
with WiFi/BlueTooth (BT/BLE). - Use
ADC1
, and pins GPIO32-GPIO39 - If somehow it's a must to use those pins serviced by
ADC2
(GPIO0, 2, 4, 12, 13, 14, 15, 25, 26 and 27), use the fix mentioned at the end of ESP_WiFiManager Issue 39: Not able to read analog port when using the autoconnect example to work with ESP32 WiFi/BlueTooth (BT/BLE).

Debug is enabled by default on Serial.
You can also change the debugging level from 0 to 4
#define ASYNC_HTTP_DEBUG_PORT Serial
// Use from 0 to 4. Higher number, more debugging messages and memory usage.
#define _ASYNC_TCP_SSL_LOGLEVEL_ 1
#define _ASYNC_HTTPS_LOGLEVEL_ 2
If you get compilation errors, more often than not, you may need to install a newer version of the ESP32 / ESP8266 / STM32
core for Arduino.
Sometimes, the library will only work if you update the ESP32 / ESP8266 / STM32
core to the latest version because I am using newly added functions.
Submit issues to: AsyncHTTPSRequest_Generic issues
- Fix bug. Add enhancement
- Add support to more Ethernet / WiFi shields
- Add support to
