I am trying to build a device that makes automatic order in Amazon when the quantity of the product in the device runs low using Amazon DRS. I had obtained the authorization code, but I am stucked in getting refresh token and access token. I am using this AmazonDRS library for my project. When I run this code the esp8266 getting reset. Please help me to get out of this.
#ifdef ESP8266
#include <ESP8266WiFi.h>
#include <WiFiClientSecure.h>
#else
#include <WiFi101.h>
#endif
#include "AmazonDRS.h"
AmazonDRS DRS = AmazonDRS();
//WiFi creds ----------------------------------------------------------------------------------
char ssid[] = ""; // your network SSID (name)
char pass[] = ""; // your network password (use for WPA, or use as key for WEP)
//------------------------------------------------------------------------------------------------------
//Extract the code from the response during the LWA process, example response below
//https://app.getpostman.com/oauth2/callback?code=ANQEgiAOjkQWjKvhNWIN&scope=dash%3Areplenish
//------------------------------------------------^^^^^^^^^^^^^^^^^^^^-----------------------
#define auth_code "ANqbDAujrtMgtplRkYgx" //ex: ANQEgiAOjkQWjKvhNWIN
int status = WL_IDLE_STATUS;
void setup() {
Serial.begin(115200);
while (!Serial) {
; // wait for serial port to connect. Needed for native USB port only
}
#ifdef ESP8266
WiFiClientSecure client;
#else
WiFiSSLClient client;
#endif
//Start up DRS
DRS.begin(&client);
//connect to WiFi
Serial.println("Initializing DRS... connecting to WiFi");
while (status != WL_CONNECTED) {
// Connect to WPA/WPA2 network. Change this line if using open or WEP network:
status = WiFi.begin(ssid, pass);
Serial.println(".");
delay(3000);
status = WiFi.status();
}
Serial.print("Connected to ");
Serial.println(WiFi.SSID());
DRS.setAuthCode(auth_code);
DRS.requestBearerAndRefreshTokens(); //only call this on initial setup - once user has authorized
//LWA for the device just use the refresh_token
delay(3000); //wait a moment for the authorization code grant to complete the exchange
DRS.retrieveSubscriptionInfo(); //test if the tokens are valid by checking slot statuses
Serial.println("Copy everything below...");
Serial.println(DRS.getRefreshToken()); //Print the refresh_token to the screen
/*copy this to AmazonTokens.h and set refresh_token equal to what's printed to the terminal
Should look like this (~460 characters)...
refresh token = "Atzr|IwEBILdfysz66E9sRHsUobHgfh1X_h-esnBfcCdYjdcCfhGRkZqXujzXSN_3a8yqj5btX1B6NgbrmEX6wax_wmJ7Sgaaa39GbR-6hjDt_tHpKsFXPGwnIhy-14CWuE4oeYDWG4pCvQ4JEMKk2DiAsuwlUtoOVwaEOif1gWErh5rswCJ8mRhaXQ7SJhZB0CWYHm_ZA_PY8xTTVTUcZFqP7iz8kBw5QGDePyOb8NvJvSuBYYkwRQTj-qrytfdcHwMWOJc5QdoyPFpmchSfsMUpMqjDmwVPBfFzb0xZWYKxdUerSeKV1VVlS4Bwl2j-4gHnjHGohUsxau4Bn9SfG9McP-7RqD9Vmk3g--rsfACQ-uVLCJSJ29sBEMNkA5sxh9E9fpTwEw166WY-xBfYa_XB9aAU3n6Fn2yFM0I7ZpPIY1fy0gkdYkFOFD0uAOdoTFDxGXwbBWE";
From now on you can use the refresh_token to authorize API calls for as long as you keep your app
authrozied for LWA in "Your Account > Manage Login with Amazon"*/
}
void loop() {
}
