Once you deploy your IoT device, you won’t have physical access to reprogram or update it. It is critical to plan ahead and to have a secure mechanism for updating your embedded system or IoT device. Sometimes you will have the requirement to update your IoT device because of a new feature update, security issues, bugs, you did not have enough time to finish something on time and you had to ship your device and etc. Since we want…

Everything in engineering is about utilizing your resources. In our case, we care about CPU or memory usage of our algorithms (at least in software engineering we do.) Yet, power consumption plays a vital role in the battery life of our IoT devices. You will want to examine and identify what part of your code, algorithm is draining your power source. Nothing provides better results than an experimental observation that is verifiable and repeatable. I will present you with…
This article is the continued investigation of the Texas Instruments BQ25570, the MPPT solar charging chip. In the following article, I will present my field tests as well as their results. I tested it with two types of solar panels, of various sizes. The tests were performed indoors as well as outdoors. The results are striking and much better than I anticipated. If your starting hypothesis was right and your lab test results were valid, then your field outcomes…
