ESP 8266 & Google OAuth
Posted: Sun Feb 20, 2022 4:04 pmLooking for some help in implementing a version of this project. I'm using an ESP8266 as a webserver for the simple page to generate a code for OAuth to approve the device and generate a Refresh Token and Access Token.
Everything works until I get to the actual point of connecting with Google servers. I'm using <WiFiClientSecure.h> but this always fails and I don't know why.
I have seen examples using client.connect, httpsClient.connect, and client_tcp.connect. none of those work. I have also tried all these connection methods with all the different URLs in the documentation given the various methods/devices including
Hoping there is someone who has been able to connect an ESP (orArduino) to Google OAuth and can help. Do I need another library for a an https connection (BearSSL)? Once I connect, do I need a certificate (google documentation doesn't indicate a certificate but not sure if that's just part of an https connection)? The aim is to connect to the Google Drive scope (https://www.googleapis.com/auth/drive.file) to upload pictures to a dedicated folder.

Code: Select all
if(!client.connect("https://accounts.google.com/o/oauth2/v2/auth", 443)){
Serial.println(F("Connection to google server failed"));
} else{
Serial.println("connected to google");
