Design, Measure, Optimize: Low-Power Bluetooth LE on the nRF54L Series
In this hands-on webinar, Ali Aljaani from Nordic Semiconductor covers the principles and design decisions that truly impact your power consumption, and how to build a realistic power budget for your product early in the design phase. Then, and most importantly, how to verify a measurement setup before you trust anything it tells you.
We will build a Bluetooth LE application together on the nRF54L Series and optimize it one change at a time, measuring after each step and comparing our measurements against our power budget predictions. By the end, you should be able to answer "how long will this run on a coin cell?" with a number, a method, and an honest margin.
