Connect to AWS IoT

On AWS Management Console

• Open the AWS IoT management console

https://eu-central-1.console.aws.amazon.com/iot/home?region=eu-central-1#/connectdevice/

Select Linux/OSX as Platform Node.js as SDK

• Create a thing e.g., "example"

• Download the connection kit for Linux/OSX

This will give you a file named "connect_device_package.zip" The package contains four files:

Content
example.cert.pem
example.private.key
example.public.key
start.sh

Execute the following command in your terminal (macOS, Linux, Git bash on Windows) to create a P12 file:

openssl pkcs12 -export -in example.cert.pem -inkey example.private.key -out example.p12

This will ask you for an export password. You have to specify this later in the MQTTAnalyzer app. So make sure to remember it.

Open the start.sh file. You will find the host-name in the last command. Example: 123456abcdefgh-ats.iot.eu-central-1.amazonaws.com

You can also find this endpoint on the AWS settings page.

Create an access policy

Without this, you will get a "Socket closed by remote peer" error after connecting to the broker.

Create a new policy: https://eu-central-1.console.aws.amazon.com/iot/home?region=eu-central-1#/create/policy

Setting	Value
Policy name	All
Policy effect	Allow
Policy action	*
Policy resource	*

Select create to create the policy.

Open the certificate page: https://eu-central-1.console.aws.amazon.com/iot/home?region=eu-central-1#/certificatehub

Select your certificate and attach the All policy to this certificate.

Open MQTTAnalyzer

• Create a new broker setting in MQTTAnalyzer
• Paste the hostname, select the option Use default settings for AWS IoT. This will update the port number to 8883 and activate SSL with certificate.
• Copy the P12 file you have previously created to the MQTTAnalyzer folder in iCloud or directly to your device.
• Select the certificate
• Enter the password that you have chosen for the P12 file
