Feed: The Internet of Things on AWS – Official Blog. Author: Chris Azer. In industrial automation, you will find dozens of protocols used by devices and PLC vendors: OPC-UA, Modbus TCP, serial, and more. In fact, often in just one facility, it is common to find two similar processes performing the same function with different equipment.AWS Greengrass reduces the operational overhead for businesses to change protocols as needed through remote deployments. AWS Greengrass uses AWS Lambda, a service that makes it possible to program devices in the cloud. For example, a business can deploy AWS Lambda functions to field devices ... Read More

Feed: The Internet of Things on AWS – Official Blog. Author: Gus Liu. X.509 certificates are used to ensure secure communication between IoT devices and AWS IoT Core. Devices use these certificates to connect to AWS IoT Core using TLS mutual authentication. AWS IoT Core uses TLS mutual authentication to encrypt data as it moves between AWS IoT Core and other devices or other AWS services. A X.509 certificate installed on devices must meet either of the following conditions: It must be issued by AWS IoT Core. The CA certificate used to sign an IoT device certificate must have already been ... Read More

Feed: The Internet of Things on AWS – Official Blog. Author: Kevin Oleniczak. The interest in machine learning for industrial and manufacturing use cases on the edge is growing. Manufacturers need to know when a machine is about to fail so they can better plan for maintenance. For example, as a manufacturer, you might have a machine that is sensitive to various temperature, velocity, or pressure changes. When these changes occur, they might indicate a failure.Prediction, sometimes referred to as inference, requires machine-learning (ML) models based on large amounts of data for each component of the system. The model is ... Read More

Feed: The Internet of Things on AWS – Official Blog. Author: Amanda Le. In an earlier Using Over-the-Air Updates with AWS IoT Device Management blog post, we showed you how to create a simple AWS IoT snapshot job and track its progress. In this post, we will show you step-by-step how to configure and create an AWS IoT continuous job. A continuous job is a long running job that reacts to changes to your deployment targets by automatically deploy job executions. For example, a continuous job can be deployed to an initial group of 100 devices. When new devices are ... Read More

Starting today, Greengrass ML inference includes a pre-built Chainer package for all devices powered by Intel Atom, NVIDIA Jetson TX2, and Raspberry Pi. So, you don’t have to build and configure the ML framework for your devices from scratch. With this launch, we now provide pre-built packages for three popular machine learning frameworks including TensorFlow, Apache MXNet, and Chainer. This blog post shows how to use Chainer with AWS Greengrass ML.As a deep learning framework, Chainer Neural Network has been added to Greengrass MLI for several reasons. Empowers ... Read More

Feed: The Internet of Things on AWS – Official Blog. Author: David Weinstein. AWS IoT Analytics is a fully managed service that you can use to query and generate insights about your IoT data. You might want to use AWS IoT Analytics on data that is not being sent to the AWS IoT Core message broker. By using the AWS IoT Analytics BatchPutMessage API, you can ingest data directly into AWS IoT Analytics from other data sources. This blog post demonstrates how to use the BatchPutMessage API to upload data stored in Amazon S3 to AWS IoT Analytics. We’ll first walk through some ... Read More

Feed: The Internet of Things on AWS – Official Blog. Author: Rahul Sareen. Application Layer Protocol Negotiation (ALPN) is an extension to TLS that enables clients connecting to a TLS server to pass an extra parameter, known as a ProtocolNameList. The ProtocolNameList is a preference-ordered list of the application protocols that the client would like to use to communicate. AWS IoT Core now allows you to connect devices over MQTT with TLS client authentication on port 443 using the ALPN TLS extension. For background about why this is useful, see this blog post.In this blog post, I will walk you ... Read More

Feed: The Internet of Things on AWS – Official Blog. Author: Steve Harris. Whether it’s a firmware update or security patch, an update to a config file on a device, or a factory reset, all products need maintenance after they are in your customers’ hands. And to manage your fleet, you need to know which devices in your fleet have received and processed, either successfully or unsuccessfully, any of your updates. AWS IoT Device Management facilitates the deployment and tracking of management tasks to your fleet of devices with the Jobs service, whether you manage hundreds, thousands, or even millions ...

Feed: The Internet of Things on AWS – Official Blog. Author: Richard Elberger. Last month, Texas Instruments (TI) launched Code Composer Studio (CCS) version 8, which includes the TI MCU compiler version 18.1.1. The Amazon FreeRTOS project for Code Composer Studio is configured for the TI MCU compiler version 16.9.3. Amazon FreeRTOS includes the open source Concise Binary Object Representation (CBOR) Library (tinycbor), which does not compile with version 18.1.1. Amazon FreeRTOS does not build when there is no preexisting 16.9.3 compiler (or compatible compiler) on the system. In this blog post, I’ll show you how to add the TI MCU compiler ... Read More
