/**************************************************************
|
|
*
|
|
* This sketch connects to a website and downloads a page.
|
|
* It can be used to perform HTTP/RESTful API calls.
|
|
*
|
|
* For this example, you need to install ArduinoHttpClient library:
|
|
* https://github.com/arduino-libraries/ArduinoHttpClient
|
|
* or from http://librarymanager/all#ArduinoHttpClient
|
|
*
|
|
* TinyGSM Getting Started guide:
|
|
* https://tiny.cc/tinygsm-readme
|
|
*
|
|
* SSL/TLS is not yet supported on the Quectel modems
|
|
* The A6/A7/A20 and M590 are not capable of SSL/TLS
|
|
*
|
|
* For more HTTP API examples, see ArduinoHttpClient library
|
|
*
|
|
* NOTE: This example may NOT work with the XBee because the
|
|
* HttpClient library does not empty to serial buffer fast enough
|
|
* and the buffer overflow causes the HttpClient library to stall.
|
|
* Boards with faster processors may work, 8MHz boards will not.
