Building a tracker with Wi-Fi, Bluetooth, LoRa, and GPS doesn't have to mean living on a charger. This post walks through the exact moves that took our ESP32-S3 design from "dies by dinner" to "runs for weeks," from hunting down sneaky always-on leaks to
Eliminate server upload bottlenecks with presigned URLs, enable massive file uploads via multipart, and automate storage archival for significant ongoing savings. Building a media-heavy application means handling large files, video, images, documents, efficiently without bottlenecking your application servers. Whether you're processing video, managing user-generated media, or handling document
A guide to CAN controllers, transceivers, and bus configuration When our team began developing IoT devices for a pet environment platform, we faced a critical challenge: transmitting high-resolution sensor data between multiple ECUs with microsecond-level timing precision. We needed CAN FD. But CAN FD isn't just "CAN,
At Hoomanely, we move beyond theoretical limits to ensure our connected products deliver predictable, robust performance in the field. Our goal for the IoT sensor network was to maximize the potential range of LoRa. By establishing and rigorously enforcing three core RF design principles from the initial PCB layout, we
Bluetooth Low Energy links don't fail in the lab, they fail in the real world. Phones roam between rooms, radios get noisy, apps get backgrounded, and peripherals reboot at the worst possible moment. After shipping connected devices at scale, the lesson is that reliability isn't about
Introduction We're building technology that helps us understand pets better, not just visually but through sound. Dogs communicate through subtle cues: the rhythm of a chew, a quiet gulp, a bark that changes tone when they're anxious. At Hoomanely, our smart bowls and monitoring systems use
Automate Flutter deployments with Fastlane: reduce release time 70%, eliminate version errors, and achieve reproducible releases across your team.
Introduction In specialized fields, the goal is a smarter system, not just a bigger one. Scaling large language models gets a lot of attention, but real gains often come from fixing the backend, and in a Retrieval-Augmented Generation pipeline, that backend is largely chunking. At Hoomanely, we kept running into
How dual-bank architecture enables seamless, zero-downtime firmware updates via CAN Firmware updates are crucial for modern embedded systems, enabling remote device maintenance, feature additions, and security patches without physical access. This post covers a production implementation on the STM32H562, which features a dual-bank flash architecture enabling seamless firmware updates through
