Dynamic memory allocation in C is a powerful tool but also a potential source of hard to replicate bugs. This post goes over tools that are built into Zephyr that monitor consumption over time.
Creating a filesystem separates your everyday firmware from other data like machine learning models, images, and binaries. In this post we discuss how you can set up the filesystem to speed up your production and create a flexible system that can be updated on-demand using Golioth's OTA service.
Bluetooth HCI enables any chipset to act as a peripheral to a processor running a Bluetooth stack. We pair the ESP32-C3 HCI with a processor running Zephyr to turn Golioth's development platform--the Aludel Elixir--into a Bluetooth gateway.
Fuel gauge ICs offload effort when it comes to taking reliable battery readings and estimating charge and drain times. Zephyr's support for these components makes using them even easier.
Sniffing network packets from a cellular modem is actually pretty easy. It only seems daunting because at first glance you're left wondering how to acquire the packets. Nordic's nRF91 modems have a trace capability that can be used to pipe packets from the device into Wireshark over a USB connection. Here's how to use it.
The Zephyr shell subsystem will help you directly interact with and troubleshoot your IoT hardware. This post details our most commonly used commands, as well as a listing of all Zephyr shell modules that we could extract from a recent project.
