This is an ESP32 / ESP8266 WiFi Connection Manager with fallback web configuration portal. Use this library for configuring ESP32, ESP8266 modules' WiFi, etc. Credentials at runtime. You can also specify static DNS servers, personalized HostName, fixed or random AP WiFi channel. With examples supporting ArduinoJson 6.0.0+ as well as 5.13.5- .

Simple way to control your IOT development boards like ESP8226, ESP32, Arduino SAMD21, Adafruit SAMD21, SAMD51, nRF52, STM32, Teensy, SAM DUE with Amazon Alexa or Google Home

This is simple yet complete WebServer library for AVR, Portenta_H7, Teensy, SAM DUE, SAMD21/SAMD51, nRF52, STM32, RP2040-based, etc. boards running Ethernet shields. The functions are similar and compatible to ESP8266/ESP32 WebServer libraries to make life much easier to port sketches from ESP8266/ESP32. Coexisting now with `ESP32 WebServer` and…

This MySQL_MariaDB_Generic library helps you connect your boards directly to a MySQL / MariaDB server, either local or cloud-based, so that you can store / retrieve data to / from the server. Supported boards are ESP8266/ESP32, WT32_ETH01 (ESP32 + LAN8720A), nRF52, SAMD21/SAMD51, STM32F/L/H/G/WB/MP1, Teensy, SAM DUE, Mega, RP2040-based boards, P…

mDNS Library for nRF52, SAMD21, SAMD51, SAM DUE, STM32F/L/H/G/WB/MP1, AVR Mega, RP2040-based boards, etc. using Ethernet W5x00. Supports mDNS (Registering Services) and DNS-SD (Service Discovery). Ethernet_Generic library is used as default for W5x00

ESP_DoubleResetDetector is a library for the ESP32/ESP8266 Arduino platform to enable trigger configure mode by resetting twice.

Simple GSM shield Manager for Blynk and ESP32 / ESP8266 boards, with or without SSL, configuration data saved in SPIFFS / EEPROM. This library enables user to include both Blynk GSM/GPRS and WiFi libraries in one sketch, run both WiFi and GSM/GPRS simultaneously, or select one to use at runtime after reboot.

A simple library that implements port mappings to router using UPnP SSDP for Arduino boards, running on nRF52, SAMD21/SAMD51, STM32F/L/H/G/WB/MP1, Teensy, RP2040-based boards, WT32_ETH01, Portenta_H7, etc. besides ESP8266/ESP32, using ESP WiFi, WiFiNINA, Ethernet W5x00, ESP8266/ESP32 AT-command WiFi, Portenta_H7 Murata WiFi or Vision-shield Ethe…

This library enables you to use Interrupt from Hardware Timers on an SAMD-based board. These SAMD Hardware Timers, using Interrupt, still work even if other functions are blocking. Moreover, they are much more precise (certainly depending on clock frequency accuracy) than other software timers using millis() or micros(). That's mandatory if you …

This library enables you to use Interrupt from Hardware Timers on an Arduino, such as Nano, UNO, Mega, etc. It now supports 16 ISR-based timers, while consuming only 1 hardware Timer. Timers' interval is very long (ulong millisecs). The most important feature is they're ISR-based timers. Therefore, their executions are not blocked by bad-behavin…

Enables WiFiNINA network connection (local and Internet) for SAM DUE, SAMD21, SAMD51, Teensy, AVR Mega, STM32, RP2040-based boards, etc. in addition to Arduino MKR WiFi 1010, Arduino MKR VIDOR 4000, Arduino UNO WiFi Rev.2 , Nano 33 IoT, Nano_RP2040_Connect. Now with fix of severe limitation to permit sending much larger data than total 4K

This is an ESP32 (including ESP32-S2 and ESP32-C3) / ESP8266 WiFi Connection Manager, using ESPAsyncWebServer, with fallback web configuration portal. Use this library for configuring ESP32, ESP8266 modules' WiFi, etc. Credentials at runtime. You can also specify static DNS servers, personalized HostName, fixed or random AP WiFi channel. With ex…

Library using AsyncWebServer to configure MultiWiFi/Credentials at runtime for ESP32 (including ESP32-S2 and ESP32-C3) and ESP8266 boards. You can also specify DHCP HostName, static AP and STA IP. Use much less memory compared to full-fledge WiFiManager. Config Portal will be auto-adjusted to match the number of dynamic custom parameters. Option…

Simple TLS/SSL Ethernet WebServer, HTTP Client and WebSocket Client library for for AVR, Portenta_H7, Teensy, SAM DUE, SAMD21, SAMD51, STM32F/L/H/G/WB/MP1, nRF52 and RASPBERRY_PI_PICO boards using Ethernet shields W5100, W5200, W5500, ENC28J60 or Teensy 4.1 NativeEthernet/QNEthernet. It now supports Ethernet TLS/SSL Client. The library supports …

This library enables you to use Interrupt from Hardware Timers on an STM32F/L/H/G/WB/MP1-based board. These STM32F/L/H/G/WB/MP1 Hardware Timers, using Interrupt, still work even if other functions are blocking.
