Install any required dependencies and test the setup by running a simple script to send and receive messages. This step ensures that your Raspberry Pi is ready to connect to AWS VPC and start transmitting data securely.
Configuring AWS VPC for IoT
Before connecting your Raspberry Pi to AWS VPC, you need to configure the VPC environment. This involves creating subnets, setting up security groups, and configuring routing tables. Follow these steps to prepare your AWS VPC for IoT:
Creating a VPC
Log in to the AWS Management Console and navigate to the VPC dashboard. Click on "Create VPC" and specify the IPv4 CIDR block for your network. Choose a block size that accommodates the number of devices you plan to connect. Once the VPC is created, note down the VPC ID, as you will need it for subsequent configurations.
Setting Up Subnets
Subnets divide your VPC into smaller, isolated networks. Create public and private subnets to separate internet-facing resources from internal ones. Public subnets are used for devices that require internet access, while private subnets are ideal for IoT devices that need to remain isolated. Assign appropriate CIDR blocks to each subnet and associate them with the VPC.
Configuring Security Groups
Security groups act as virtual firewalls for your VPC resources. Create a security group for your IoT devices and define inbound and outbound rules to control traffic. For example, allow inbound traffic on specific ports for MQTT communication and restrict access to trusted IP addresses.
