The choice of protocols depends on various factors such as the nature of devices, network constraints, and the specific requirements of the IoT application. Here's a contextual overview of how protocols fit into the IoT landscape: 1. Diverse Ecosystem: - IoT encompasses a diverse ecosystem of devices ranging from sensors and actuators to smart appliances and industrial machines. - Different devices may have distinct communication needs, influencing the selection of protocols. 2. Resource Constraints: - Many IoT devices operate under resource constraints, including limited processing power, memory, and energy. ...

This architecture ensures that firmware updates can be delivered seamlessly and securely to the devices in the field. Here's an outline of the architecture with explanations and examples: 1. Device Firmware: - The IoT devices (escalators, elevators) have embedded firmware that needs to be updated over the air. - Example: The firmware manages the operation of the device, and we want to update it to fix bugs or add new features. 2. Update Server: - A central server responsible for managing firmware updates and distributing them to the devices. - Example: A cloud-based server that hosts the latest firmware versions. 3. Updat...

Optimize Your Model: - Use a model that is optimized for edge devices. Some frameworks like TensorFlow and PyTorch offer quantization techniques and smaller model architectures suitable for resource-constrained devices. - Prune your model to reduce its size by removing less important weights or neurons. 2. Accelerated Hardware: - Utilize hardware accelerators if your Raspberry Pi has them. For example, Raspberry Pi 4 and later versions have a VideoCore VI GPU, which can be used for certain AI workloads. - Consider using a Neural Compute Stick (NCS) or a Coral USB Accelerator, which can significantly speed up inferencing f...

Addressing resource-heavy issues in a microservices application running in Dockerized containers on an ARM-based Toradex microcontroller requires a systematic approach. Here are steps to check, verify, and fix these issues: 1. Resource Monitoring:    - Use monitoring tools like `docker stats`, `docker-compose top`, or specialized monitoring tools like Prometheus and Grafana to monitor resource usage within Docker containers.    - Check CPU, memory, and disk utilization for each container to identify which service or container is causing resource bottlenecks. 2. Identify Resource-Hungry Containers:    - Look for containers that are consuming excessive CPU or memory resources.    - Pay attention to specific microservices that are consistently using high resources. 3. Optimize Microservices:    - Review the Docker container configurations for each microservice. Ensure that you have allocated the appropriate amount of CPU and memory resource...

  Photo by Markus Winkler on Unsplash Often you need to implement Machine Learning application into the EDGE devices. So IoT devices running your machine learning or other artificial intelligence application required updates time to time when you update ML models or back end application or some other part of the application running on IoT. Over-the-Air (OTA) updates for IoT devices running machine learning applications refer to the capability of remotely updating the software and machine learning models deployed on IoT devices. This enables device manufacturers and developers to deliver bug fixes, security patches, feature enhancements, and even model updates to deployed devices without physically accessing or manually updating each device. Implementing OTA for IoT devices running machine learning applications involves the following key steps: 1. Remote Software Management: OTA updates require a robust infrastructure to remotely manage and distribute software updates to IoT devices...
