Exciting Challenges
Day-to-day problems when working with IoT
Energy Efficiency
Not all devices can be attached to a socket. How can we
be sure the battery life is long enough to perform tasks?
Connectivity
How to connect thousand of devices that use different
protocols on all layers, starting from the physical layer?
Security
How to exchange data in a secure way? Can we trust other
parties? How do we protect from impostors?
Economic Feasibility
Technological progress allows creating amazing things. The
only problem is… the price!

Connectivity
Problem one
Application Layer
MQTT is the most popular and was specifically designed for
IoT applications. Vendors also have proprietary protocols.
Challenges
Unstable connection, high latency, frequency usage
regulations and interference.
Physical Layer
Wired connection, LTE, Lo-Ra, Wi-Fi, BLE, ZigBee, others.

Security
Problem two
Data Transfer
Encryption at rest and in-transit
Performance
Dedication encryption/security chips, efficient algorithms
Device Modification
Fuse flags, tamper detection

Economic Feasibility
Problem four
Maintenance Costs
Once the solution is “in the field”, the support should be
affordable
Profitability
The device or a combination of device and the service should
be profitable in order to make the business sustainable
Production Costs
Make sure the resulting solution can be implemented within
available budget

Approaches to Solving
Exciting Challenges
Check Other Areas
Are there any similar problems in other areas, not connected
with my product? Are there any desired effects in nature?
Check Standards and Existing Protocols
Maybe the problem can be solved using existing standards or
protocols. Don’t reinvent the wheel without a need!
Find Inspiration in Existing Solutions
How do other solve these problems? To be better you need to
match existing solutions first.
Invent or Reinvent!
Sometimes you just have to invent new things, maybe even
break existing standards and approaches!

Get an AWS Account and The Button
Step 1
Get AWS IoT Button or AWS IoT Enterprise 1-Click IoT Button
You can buy both on Amazon. No need to wait for delivery -
events can be simulated from AWS Management Console!
Visit AWS Website
You can find it here: https://aws.amazon.com/
Register for a Free Tier Account
You will have 12 mont of Free Tier access. The Free Tier is a
certain amount of AWS services you can use for free.
Proceed to the configuration
It’s time to connect the real world and the cloud

15. © 2019 AgileVision sp. z o.o. 15
Configure the Button
Step 2
Troubleshoot error codes
If there is an issue, the button blinks with red or orange. All
error codes can be found here: https://docs.aws.amazon.com/
iot-1-click/latest/developerguide/button-guide.html
Download the provisioning application
You can find it here: https://docs.aws.amazon.com/iot-1-click/
latest/developerguide/1click-mobile-app.html
Open the app and follow instructions on the screen
You will need to perform several simple steps to finish the
configuration

Evolve!
Step 6
Use ML-based prediction of cookies utilization
How many packs should we order? ML can help with that!
Connect AWS DeepLens to recognize the person who took the last cookie
Last cookie dilemma is among Top-10 mysteries unsolved by the humanity. People
say the last cookie disintegrates and turns into a quantum dust.
Use Food Delivery API
It’s possible to further automate the process by reordering cookies via a food delivery
service API.
Announce cookies arrival with a voice!
You can use Amazon Polly and make an audio announcement
each time cookies arrive.
