This repository provides a step by step guide on creating your first Wi-Fi Simple Setup enabled device

Introduction

This repository provides a step by step guide to creating your first device compatible with Wifi Simple Setup from Amazon. Wifi Simple Setup (WSS) is a part of the Frustration Free Setup program from Amazon which focuses on simplifying the smart home setup experience for customers. For more on the program, please visit https://developer.amazon.com/frustration-free-setup

WSS Sample Device Setup with ZTS

The following are the tasks to run the demo:

1. Request a New Device Identifier and Attestation Keys

2. C SDK Prerequisites

3. Download and Run WSS C SDK

4. Build WSS SDK with AWS IoT for embedded Linux.

5. Partner Cloud Prerequisites

Request for BearerToken returns a 400

Hi @ramezab!
So I have been trying to run the WSS sample, but I am facing an issue with getting the bearer token.
Here's a minimum working example to obtain a bearer token that the SDAE request must have:

import http.client
import json

clientId='amzn1.application-oa2-client.xxxx..'
clientSecret='secrethashgoeshere'

lwa_uri = 'api.amazon.com'
connection = http.client.HTTPSConnection(lwa_uri)
lwa_headers = {
    'Content-Type': "application/json;charset=UTF-8",
    'Cache-Control': "no-cache"
}
lwa_payload = {
    "grant_type": "client_credentials",
    "client_id": clientId,
    "client_secret":clientSecret,
    "scope": "alexa::device_association_report:write"
}
connection.request('POST', '/auth/o2/token', json.dumps(lwa_payload), lwa_headers)
response = connection.getresponse()

lwa_result = json.loads(response.read())
print('[LOG] HTTP Status code: ' + str(response.getcode()))
print('[LOG] LWA returned: ' + json.dumps(lwa_result))

I have tried running this with the Id-Secret pair obtained from my Alexa Smart Home Skill config page, but I get a:

[LOG] HTTP Status code: 400
[LOG] LWA returned: {"error_description": "The request has an invalid parameter : scope", "error": "invalid_scope"}

I also tried creating a LwA Security Profile from this page and got another Id-Secret pair from there, that had the same format, but even that gives me the same result.

Any idea what might be going wrong?

the device keys can't pass verification during the PROVISIONING stage

after Request a New Device Identifier and Attestation Keys step, we replace the keys we get from Amazon, during the Execute Wi-Fi provisionee state START_PROVISIONING stage, device post the nonce:

POST /api/v1/startProvisioningSession HTTP/1.1
Content-Length: 43
Host: dp-sps-na.amazon.com
Content-type: application/json

{"nonce":"iUryyB6ecF5BPC6FTJfOUuhIxhhP32m"}

then server response body is :

{"canProceed":false,"waitTime":"PT30S"}

which cause the WSS C SDK can't continue to next step anymore, Can anyone help to fix this problem?
