Mike is a Firmware Engineer at Golioth. His deep love of microcontrollers began in the early 2000s, growing from the desire to make more of the BEAM robotics he was building. During his 12 years at Hackaday (eight of them as Editor in Chief), he had a front-row seat for the growth of the industry, and was active in developing a number of custom electronic conference badges. When he's not reading data sheets he's busy as an orchestra musician in Madison, Wisconsin.

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.
