Power Optimization Recommendations using Zephyr
In this post, we look at the absolute minimum current drawn by the nRF9160 SOC when peripherals and modems are turned off, using the Power Profiler Kit 2 (PPK2) to measure the current consumption.

Measuring Current Consumption with Power Profiler Kit II
IoT devices are usually battery-operated and, more often than not, need to run on a single battery charge for multiple years. Before we know it, MCU power consumption becomes a huge deal when developing a product. Measuring power consumption of an MCU can be challenging since it does not depend on just one thing. It […]
Troubleshooting IoT Cellular Connections with Nordic nRF9160
Cellular connected IoT can be intimidating, especially when the cellular connection doesn’t work, or only works intermittently. Today we will explore Nordic’s LTE Link Monitor and Cellular Monitor applications to show how you can troubleshoot cellular connection using the nRF9160 DK as the development board. Programming the modem firmware The modem allows applications to send […]
How To Manually Send Data to LightDB State and LightDB Stream
We always recommend connecting ESP32 devices to the Golioth Cloud with the Golioth Firmware SDK. We believe that is the lowest friction way of connecting a device to the internet. But sometimes I want to get under the hood and tinker, and I thought you might like to see how that works as well. We […]
Switching Between LTE-M and NB-IoT Cellular Standards in Zephyr
It’s a tale as old as IoT. You get a project with a cellular connection working, but when you move to a different physical location, all of a sudden you cannot connect to the internet. You know your network provider has cellular coverage in the area, and your SIM card is paid up. So why […]
