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.
Agricultural irrigation is a perfect application for IoT. Golioth's latest reference design demonstrates how to report soil moisture sensor data to the cloud. Acting on this data, you can dial in the perfect balance of natural rainfall and irrigation for the best crop yield.
How do you ensure you achieve the lowest possible power with your Cellular IoT Devices? We held a webinar on January 18th, 2023 where we tackled this question.
