How to Control LTE with the Nordic nRF9160 and Golioth

Here’s how to control the nRF9160 cellular modem, and what to do about your connection to Golioth when the modem is turned off. When building cellular IoT devices, the modem is often the most costly component in terms of power budget. Connecting to an LTE network also takes time. In both cases, manual control of the LTE connection means you make all the decision on when and how the radio is used.

Change Logging Levels From Afar with Golioth

Golioth includes remote logging as a core feature. However, for devices operating on a cellular network, you don’t want to use bandwidth for logging messages unless they are really needed. This post discusses how to use Golioth and Zephyr RTOS to set device logging levels remotely.

Nordic’s brand new nRF7002 Wi-Fi chip already works with Golioth

The nRF7002 is a brand new WiFi chip from Nordic Semiconductor released earlier this month. Getting it up and running with Golioth is easy. Update NCS to the tip of main to pull in the newest driver work from Nordic, and make a configuration file for this board. Eli Hughes shows us how in this guest post.

Why calibrate? IoT systems work with raw data

One of my first engineering jobs was in the Test and Measurement space. Tracing everything back to standards and calibration is a key part of the process. It takes a long time and is taken very seriously. I had many learning experiences that reinforced the importance of calibration (despite my tongue-in-cheek article title). IoT devices […]

IoT Greenhouse Controller: A Golioth Reference Design

The Internet of Things (IoT) can make existing infrastructure more useful and easier to operate, with the added benefit that you don’t need to be on-site to make changes. This is the case with Golioth’s latest reference design: a greenhouse controller that adjusts ventilation and grow lighting based on sensor readings. It also provides manual […]
