AsyncTCP, AsyncUDP, AsyncWebServer and AsyncHTTPRequest for Portenta_H7, supporting both Ethernet and WiFi now

Official Hardware Portenta Family Portenta H7

Portenta_H7_AsyncHTTPRequest Library

Features

  1. Asynchronous HTTP Request library for Portenta_H7 using Murata WiFi or Vision-shield Ethernet.
  2. Providing a subset of HTTP.
  3. Relying on on Khoi Hoang's Portenta_H7_AsyncTCP
  4. Methods similar in format and usage to XmlHTTPrequest in Javascript.

Supports

  1. GET, POST, PUT, PATCH, DELETE and HEAD
  2. Request and response headers
  3. Chunked response
  4. Single String response for short (<~5K) responses (heap permitting).
  5. Optional onData callback.
  6. Optional onReadyStatechange callback.

Principles of operation

This library adds a simple HTTP layer on top of the Portenta_H7_AsyncTCP 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.

Initial Releases v1.0.0

  1. Initial coding to support Portenta_H7 boards such as Portenta_H7 Rev2 ABX00042, etc., using ArduinoCore-mbed mbed_portenta core with Vision-shield Ethernet ot Murata WiFi
