Golioth Hardware at Sensors Converge Conference
Golioth is showcasing at the Sensors Converge Booth as part of Digikey’s booth. Stop by to see how Golioth can connect a wide range of hardware using one codebase in Zephyr.
How to Get Network Information from a Nordic nRF9160 Cellular Modem
Cellular-enabled devices are often deployed into far-flung locations. They are quite likely to be out of reach from physical access once deployed. Having a way to verify the network status for a device is really important to maintaining a fleet. Nordic Semiconductors (makers of the nRF9160) built tools for returning cellular connection info into the […]
CBOR Serialization in the Golioth Zephyr SDK: 20% Data Savings!
Golioth provides a lot of different services for your IoT fleet. Under the hood they all boil down to one thing: transferring some type of data to or from a constrained device. Whether it’s your microcontroller-based sensors sending back readings, or the new settings from the cloud being pushed to a device via Remote Procedure […]
Using the Nordic nRF7002-DK for Zephyr Training
Golioth is building a new training using Nordic Semiconductor’s nRF7002-DK board. We think this is an affordable, flexible platform for getting started learning Golioth, Zephyr, and Nordic components.
Cold Chain Asset Tracker: A Golioth Reference Design
How do you ship something over large distances and ensure it stays cold? Logistics and medical companies need to ensure proper storage throughout the life of the product, from frozen food to vaccines. This reference design shows you how.
Upcoming Webinar: How to collect data from IoT sensors using Golioth and Modus Toolbox™
Please join us on Wednesday, April 19th 2023 for a webinar about using Golioth to collect IoT sensor data. The session will detail how to use the Infineon ModusToolbox™ to add Golioth device management. This webinar will include Golioth team members alongside Clark Jarvis, a Senior Staff Technical Marketer at Infineon Technologies. He will present […]
How to Use JSONata in Grafana to Validate Data
JSONata is language to parse information coming back from the Golioth REST API. This article showcases how to use the language to pull data out of complex query return strings.
How Golioth Built a User Interface with ePaper and Back-lit LEDs for Our IoT Hardware
Golioth’s new custom hardware is an ePaper-based user interface that works with all of our reference designs. All it takes is Qwiic cable to connect to the i2c bus, and sensor readings and other information begins streaming to the face plate. Let’s take a look!
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.
