Setup your AWS account and Permissions
Users do NOT need to setup AWS account, user will be using Dexatek's cloud infrastructure. After user purchases
Dexatek's device, the user only needs to download the APP and sign up via APP. All the required permissions will
be granted to the user, due to the integration between AWS Cognito User Pool and Identity Pool. If the User
wants/needs to setup their own environment, user will need to send an email to Dexatek
([email protected]), Dexatek's engineer will contact and support them.

Create Resources in AWS IoT
Resources are created when pairing, these are the steps
a. User presses the reset button for 3 seconds on the device, the device becomes "pairing mode"
b. User turns on the "Bluetooth" of their phone,
c. User opens our APP and follows the pairing wizard
d. Once APP receives all the information it needs, then APP sends the payload to a Lambda API called
"AddDevice", developed by Dexatek, by making this HTTP POST call("AddDevice"), Lambda API returns an
OTP(One-Time Password). Noted: Most of the IoT Resources are created in this step, "AddDevice" API helps to
create "IoT Things", "IoT Device Shadow", "Map to the correct thing type" and "create IoT Policy", and users don't
need to create manually. Device Certificate has not yet been generated and Device has no IoT Core permission or
